The Nature and Classification of Transmission Chain

    First, the Transmission Chain drive the machine, the commonly used transmission member has pulleys, gears, worm turbine, gear rack and screw nut. Through these sources of power transmission parts, right and implementing agency, or the link between the two agencies, known as transmission links. Forming a series of drive link order of transmission parts called transmission chain.
  Second, the Transmission Chain generally contains two types of transmission: one is the direction of transmission and the transmission ratio of the transmission mechanism are fixed, such as fixed-ratio gears, worm turbine vice, etc., known as fixed-ratio drive mechanism; another is based on the processing requirements can change the direction of the transmission ratio and the drive transmission mechanism, such as hanging wheel gear mechanism, the sliding gear transmission mechanism, etc., known displacement mechanism.

Transmission chain

   Third, according to the nature of the transmission link, transmission chain can be divided into two categories:
  （1）The inner Transmission chain link it to contact the movement of the actuator itself (for rotary and linear movement) based on the motion analysis, the same part of a separate trip movement, and thus the implementation of relative motion between the components to stringent requirements. Contact with the nature of such transmission chain, drive chain, drive chain called inner contact. So contact within the instantaneous transmission chain in uncertain or changing the transmission ratio of the transmission mechanism, such as the belt drive, chain drive, friction drive and so on. For example, in horizontal lathe threaded connection between the threaded spindle and turret drive gear ratio is a contact within the strict requirements of the transmission chain, it can ensure the desired pitch and get the thread.
  （2）The outer contact contact sport Transmission chain which is the source and the machine actuator between the drive chain. It enables the actuator to obtain a predetermined speed of movement, and a power drive, but does not require the original motion between the source and perform a strict relationship between the transmission ratio. Contact transmission chain outside the transmission ratio changes are only affect productivity and surface roughness, the surface does not affect the formation of the shape.

About Tyre Coupling classification and characteristics

   Definition
   Tyre Coupling is divided into two major categories of convex and concave, convex with a skeleton is divided into integral, integral and radial boneless cuts three. Ring inside the tire vulcanization bonding method and integrated steel skeleton, the skeleton of the bolt hole welded nuts. When mounting the coupling halves with bolts and a flange connection, tighten the screws of the tire depend on the flange end face of the frictional force generated between the torque transmission, the tire ring at the work place torsional shear deformation, the Tyre Coupling With its high flexibility, the relative displacement of two-axis compensation capacity is large, and has good damping, and the structure is simple, without lubrication, disassembly and maintenance more convenient.
   The disadvantage is not high carrying capacity, larger dimensions, with the two axes relative twist angle increases twisted shape of the tire, the axial dimension decreases slightly greater in the two axes of the additional axial force, the bearing load increase and decrease life. Coupling high speed tires, the tire outer outward expansion of the centrifugal force, will further increase the additional axial force. To this end, measures should be taken in installing the coupling, so that the stress in the direction of the tire and the stress generated when the work in the opposite direction, to offset part of the additional axial force, to improve the work of couplings and two bearings and conditions.
   Classification and Characteristics
    Tyre Coupling main models: UL Tyre Coupling, LLB Tyre Coupling, LLA Tyre Coupling, DL polygonal rubber coupling, LAK saddle-shaped blocks and other types of flexible coupling, UL type, LLB type, LLA type is more commonly used in several models.

How maintenance and repair Bearings

   In order to give full play to the bearing and long maintained its proper performance, you must do a good job of regular maintenance (periodic inspection).
By appropriate periodic inspection, so that early detection of failure to prevent accidents in the first place, to improve the productivity and economic importance.
    Custody
    Bearing at the factory are coated with anti-rust oil and use the right amount of rust-proof paper packaging, as long as the packaging is not damaged, the quality will be guaranteed.
However, long-term storage, to be less than 65% humidity, the temperature is about 20 ℃ under the conditions stored in the shelf 30cm above the ground is appropriate. In addition, the storage place should avoid direct sunlight or contact with the cold wall.
    Clean
    Remove the bearing inspection, photography and other methods to do first with the appearance of records. In addition, to confirm the remaining amount of lubricant and lubricant samples, and then cleaning bearings.
    a, bearing cleaning of rough wash and sperm washing and can be placed in the bottom of the container used metal grid.
    b, coarse wash, brush, etc. used in the oil or grease removal adhesive material. At this point if rotating bearings in oil, attention and other damage due to foreign objects rolling surface.
    c, sperm washing, in the oil slowly rotating bearings should be carried out carefully.
   

Linear Bearing

    Commonly used cleaning agents for the neutral water diesel or kerosene, is sometimes necessary to use warm lye. Regardless of what kind of cleaning agent filter should always be kept clean.
    Cleaned immediately after anti-rust coating on the bearing grease oil or rust.
    Inspection and judgment
    In order to determine whether the re-use of the removed bearing should focus on checking the accuracy of its size, rotation accuracy, internal clearance and with the surface, raceway, cage and ring.
    Large bearings rotated by hand because they can not pay attention to check the rolling body raceway, cage, ribs and other exterior surfaces, bearing the importance of checking the more it must be taken seriously.
    On the inspection results, may be used to bearing or bearings were judged proficient.
Determine the mechanical properties and the criteria according to the degree of importance and checking cycles vary. If the following injury, the bearings must not be reused and must be replaced.
   1) bearing parts breakage and defects.
   2) rolling surface raceway material peeling.
   Linear Bearings
   Linear bearings divided into metal and plastic linear bearings linear bearings
Metal Linear bearing is a low-cost production of linear motion system for unlimited travel in conjunction with the cylinder axis. Since carrying the ball point contact with the shaft, so the use of small loads. With minimal friction ball rotation, which can obtain high-precision smooth movement.
  Chinabase Machinery is a group of manufacturing facilities, offering one-stop solution for mechanical power transmission products in China. We can supply a full-range of power transmission products, such as chains, engineering chain，cast iron chain ，sprockets and plate wheels, pulleys, gearboxes, motors, couplings, gears and racks.

How to better remove the Bearing

    Bearings are in the process of mechanical transmission fixed and reduce the load coefficient of friction components. Can also say that when the other parts in the shaft relative motion, used to reduce friction during power transmission coefficient and holding shaft center position fixed parts. Bearings are one kind of modern machinery and equipment vital components.
      Its main function is to support the mechanical rotating body, the drive device for reducing the mechanical load during the friction coefficient. According to the different nature of friction of moving parts, rolling bearings and plain bearings can be divided into two categories.
     Linear Bearings
     Linear bearings divided into metal and plastic linear bearings linear bearings
     Metal Linear bearing is a low-cost production of linear motion system for unlimited travel in conjunction with the cylinder axis. Since carrying the ball point contact with the shaft, so the use of small loads. With minimal friction ball rotation, which can obtain high-precision smooth movement.
    Plastic Linear bearing is a self-lubricating properties of linear motion system for metal linear bearings biggest difference is that the metal is rolling friction linear bearings, bearings and point contact between the cylinder axis, so that for low-load high-speed movement; while plastic linear bearings are sliding friction between the bearing and the cylindrical shaft surface contact, so this is suitable for high load low speed movement;

Linear Bearing

     Bearing Removal
     Bearing removal is regular maintenance, when bearing replacement. After removal, if it continues to use, or still need to check the bearings of the state, its removal should be carried out with careful when installing the same. Careful not to damage the bearings of the parts, especially the interference fit bearing removal difficult operation.
     Designed according to need removal tool is also very important. In the demolition, according to the drawings of demolition methods, in order to investigate the bearing with the conditions to obtain the demolition job foolproof.
     Removing the outer interference fit of the outer ring, the circumference of the housing in advance several outer extrusion screw is provided with a screw, the screw tightened equally side, while the removal. These usually cover the screw holes blind plugs, tapered roller bearings, etc. separable bearings, shoulders set out in the housing block several incisions, the use of pads, with press dismantling, demolition, or gently pounding.
     Removal of the inner ring can be used to pull out the easiest presses. At this time, pay attention to your inner bear its pullout. Furthermore, as shown in the drawing are mostly used with Baraka, regardless of the kind of fixtures, it must be firmly stuck in the inner side. To do this, you need to consider the size of the shaft shoulder block, or research in the ditch on the shoulder block is machined to use drawing fixtures.
     Large bearing inner ring removal by hydraulic method. By setting the hydraulic pressure in the bearing hole to be so easy to pull. Large width of the bearing is oil law and drawing fixtures and use, disassembly operations.
    NU, NJ type cylindrical roller bearing inner ring disassembly can take advantage of induction heating method. Local heating in a short time, after drawing the inner ring expansion method. You need to install a large number of this type of bearing inner ring of the occasion, also uses induction heating method.
    The best in the upcoming installation,, just open bearings packaging. General grease lubrication, without cleaning, direct filling grease. Lubricating oil, do not have general cleaning, but the equipment used or high-speed bearings, etc., use a fresh oil washed to remove rust coating agent on the bearing. Removes rust bearings, rust, so you can not put aside. Moreover, the sealed bearing grease, used directly without cleaning.
   Bearing installation method, because the bearing structure, with, conditions vary, in general, due to multi-axis rotation, so the interference fit to the inner ring. Cylindrical bore bearings, multi-pressed into the press, or by hot charging method. Cone of the occasion, mounted directly on the tapered shaft, or sleeve installation.
    When mounted to the housing, generally with more clearance, the amount of interference with the outer ring, usually pressed into the press, or is installed after the cooling method of shrink fit. With dry ice as coolant, shrink with the installation, the moisture in the air condenses on the bearing surface. Therefore, the need for appropriate corrosion protection.

How casting the Gear?

    Also known as steel casting gear gears. This is because most of the gears are made of cast steel. Here, I share some of the production gear castings and heat-related information.
    Gear casting weight is usually from a few kilograms to several tons.
    Gear casting materials generally used carbon steel, some containing chromium, nickel, molybdenum alloy, in order to achieve a high tensile strength. Typically greater than that of the pinion gear physical requirements low.
About the casting process, usually on the floor molding process and to meet the normal requirements apply. As for steel gears, such as the driven gear, idler gear and using quartz sand floor molding process is a good choice. Why, because most of the parts of the gear machining is required. So, you do not need to use a higher casting process. Furthermore, regarding the large steel castings, the quartz sand on the floor molding process is almost the only choice.
    About the heat, of course, all steel castings must be standardized in order to eliminate the internal stress. Certain parts of the gear can be welded castings. If welding castings foundry, welding position must be annealed. If after hobbing high hardness, you can once again annealed to reduce the hardness and eliminates internal hard spot.    
   

China Gear

     After the processing and hobbing, gear quenching or so-called hardening treatment to improve the surface hardness of the gear teeth. For small gear, you can do carburizing treatment. For large driven gear, you can do surface hardening treatment. No hardened gear life is very short, only a few weeks to a few months.
   Since the gear castings of materials, defects, processing and heat treatment demanding. Furthermore, the gear casting a relatively small amount of orders. Thus, many steel manufacturers willing foundries.
   Some gear from the forging process. Forged Gears better internal tissue density, higher strength. Forged gear can be used for more stringent working conditions. Strong low casting gear, but widely used in general working conditions. Forged gear high cost, and relatively low cost casting gear. Buyer should be based on the cost and conditions of use choose the right manufacturing process.

Pulley introduce the principle characteristics of various types

   Hangzhou Chinabase Machinery  is a China pulleys manufacturer, produce: taper pulleys, adjustable pulleys, falt belts pulleys, china taper pulleys,sheaves, V-Belt Pullys for taper bushes,V-Belt Pulleys,V-Belt Pullys with solid hub.
    In mechanics, a typical pulley (pulley) is a circle around the central axis of the wheel. The circumferential surface of the circular wheel having a groove, the rope wound on the grooves, the force La Shengsuo Either end of pull, and the circle round the rope will lead to friction between the circle around the central axis of the wheel. Press the central axis of the pulley is moving, the pulley can be divided into "fixed pulley", "pulley"; fixed pulley center axis is fixed, the central axis of the movable pulley can be moved. The main function is to pull the pulley load force changes direction, the transmission power and so forth. Composed of a plurality of pulleys machine called a "pulley", or "double pulley." The mechanical advantage of the pulley is large, can pull heavier loads. Can also be a chain wheel or belt drive assembly, the power transmitted from a rotating shaft to the other rotating shaft.
    Pulley is deformed lever, simple machine belong leveraged, very versatile. Only effort but also can change the direction of the force. Move together with the central axis of the pulley weights called movable pulley, the lever arm is deformed unequal (effort lever), you could save half the power, but fees doubled the distance (movable pulley rise n m, string up the free end 2n m, n ≥ 0), and can not change the direction of the force. The fixed pulley cord matter where to force direction, the force used to lift weights are equal (rope weight and friction between the rope and the wheel does not count) (power arm and the resistance arms are equal and equal to the radius of the pulley); movable pulley cord vertically upward direction of the force with minimal effort.

Timing Belt Pulleys 

    Fixed pulley: use of a block, the position of the axis is called stationary pulley fixed pulley.
    Feature of the Fixed pulley
    When used, the position of the pulley fixed; essence of such fixed pulley arm lever, no effort is not strenuous, but you can change the direction of the force.
    The power lever arm and the resistance arm pulley radius, respectively, equal to the radius, so the power arm is equal to the resistance arm lever neither effort nor laborious.
    Principle of the Fixed pulley
    Such substance is fixed pulley arm lever, the power arm (L1), the resistance arm (L2) is equal to the radius of the pulley. According to the equilibrium condition lever fixed pulley can draw conclusions without effort.

    Movable pulley: position of the axis movement together with the drawn object called a movable pulley sheaves.
    Feature of the Movable pulley
    Movable pulley is essentially twice the power arm of the lever arm of the resistance, province 1/2 times the distance a little extra force.
    Position of the axis along with the movement of the pulley is drawn object, called the movable pulley. It is the arm of the lever ranging deformed, can save half power (without regard to the pulley in the case of gravity and friction), but does not change the direction of force. Using movable pulley half could save power, charge distance. This is because the use of movable pulley, the code consists of two ropes hanging hooks, each hook yard rope bear only half the weight. Although the province pulley using force, but the power is the distance between the hook moving distance code two times higher, which costs a distance. Can not change the direction of the force. And moves with the object.
    Principle of the Movable pulley
    Does not change the direction of the force, the movable pulley of the primary movable sheave is essentially a power arm (L1) of the resistance arm (L2) twice the lever.
    Pulley blocks: the fixed pulley and a movable pulley pulley block consisting of both effort but also to change the direction of force, but can not save power, because pulley saving power, but costs a distance.
   Pulley blocks Use for
   In order to not only save power but also to change the direction, can be combined into a movable pulley sheaves and pulleys. The size of effort
    When using pulleys, G G movable pulley has a few things to bear rope, lift an object that is used to force a fraction of the weight thing.
    Feature of the Pulley blocks
    Hanging rope pulley objects a few paragraphs, lift force of the object is used the total weight fraction of the free end of the rope around a pulley of the operator, bypassing the fixed pulley will not forget.
    Although the province using pulley force, but costs a distance greater than the distance traveled by heavy power distance moved. Charges mainly to see how much distance fixed pulley Rao Shengzai number of segments.
    Experiment with pulley, it is easy to see that, although the province using the pulley force, but costs a distance - dynamic movement of goods increased distance greater than the distance.

     Bushes with high degree of standardization, high precision, compact structure, convenient installation and removal. By 8 givers cone and pulleys, sprockets and other transmission parts inside the cone compression connection, make a variety of transmission parts centering accuracy greatly improved. Drogue size standard design for the series. Which bore keyway according to ISO standard processing. Interchangeability good versatility for a variety of occasions when the transmission parts after a long operation, the inner hole and chain groove damage may occur, if you are using this drogue transmission parts, When this happens, simply replace the the same size can be restored using the sleeve. Thus greatly improving transmission parts life, reduce maintenance costs and save time.
       Bushes category:  TB, QD Bushes and STB sleeve of the points, with the pulley sleeve holes are matched at the half, and put the two light cone pulley hole and two threaded holes are constitute a complete hole, a threaded sleeve tapered bore of the pulley and an optical aperture formed on a complete hole. In the assembly, the two screws in the threaded holes of the two pulleys, with the threaded screw holes on the pulley constantly tighten the screw thread action cone pulley toward the small end, the tapered sleeve two optical aperture and is not completely processed to wear, so that when the screw head against the bottom of the aperture, it will force to the sleeve, the sleeve relative to the pulley of the pulley movement small end of cone, This is because the taper reasons, drogue has continually package tight shaft, and the shaft reacts on the sleeve, and then acting on the pulley. Such pulleys, taper sleeve and the shaft assembly on tightly together.

Taper Bush

     Conversely, when removing from the exit pulley screw threaded hole on the tapered sleeve with a threaded hole in the continuous process of tightening the screw is tapered toward the small end of the pulley direction, when the screw head against the pulley light bottom of the hole, it will force transmitted to the pulley, then the pulley on the relative Bushes to the pulley small end of cone direction, so that the pulley with taper suites are out of open, while the sleeve is also because of the loss from the pulley cone hole binding, coupled with its own recovery roundness some flexibility, but also with the shaft from the open.
     When the pulley and shaft sleeve are connected together to form an interference fit connector. Cone kit with key hole and shaft connected to transmit torque through the key and force. Bushes and although there is no linkage between the pulley, but there is a positive pressure joints, resulting friction can transmit torque and force.

About the European standard Taper Bore Pulleys Ddvantages and Disadvantages

Taper Bore Pulleys type parts are generally relatively large in size, the manufacturing process generally casting, forging based. Generally designed for the use of a larger size casting methods, materials are generally cast (casting performance is better), rarely used steel (steel casting performance is poor); generally smaller in size, and can be designed to be forged, materials of steel.
     Pulley indicators and the selection of materials is able to achieve the requirements under the premise of minimizing on raw materials, technology is feasible, the lowest cost option principles! Pulley is mainly used for long-distance transmission power of the occasion, such as small diesel power output, agricultural vehicles, tractors, automotive, mining machinery, processing equipment, textile machinery, packaging machinery, lathes, forging bed, some small horsepower motorcycle powered transmission, the transmission power of agricultural machinery, air compressors, reducer, gear, generator, ginning machines and more.
    Taper Bore Pulleys advantages:
    Pulley drive can ease the load impact;
    Pulley drive smooth running, low noise, low vibration;
    Pulley drive simple structure, convenient adjustment; belt drive pulley for the manufacture and installation of precision is not as strict meshing transmission;
    Pulley drive with overload protection function;
    Pulley drive shaft center distance of two large adjustment range.

Taper Bore Pulleys

   Taper Bore Pulleys Disadvantages:
Pulley drive flexible sliding and slipping, transmission efficiency is low and can not maintain accurate transmission ratio;
    Pulley drive to deliver the same large circumferential force, the outline dimensions and shaft meshing large pressure ratio;
   Drive belt pulley shorter life.
   Types of machinery and equipment, pulley diameter and other dimensions are themselves based on gear ratio with, according to the operating speed and the motor speed of their own design. Operating speed / motor driven wheel speed = Diameter / driving wheel diameter * 0.98 (sliding coefficient), such as the use of steel as the material of the pulley, required line speed is not higher than 40m / s, such as the use of cast iron materials required line speed is not higher than 35m / s, the motor speed and pulley diameter conversion ratio, speed ratio = Output speed: input speed = load pulley pitch diameter: motor pulley pitch diameter. And the reference pitch diameter is the same diameter, the diameter-2h = pitch circle diameter, h is the groove depth of the reference line, the different types of V-belt and h is not the same, YZABCDE, respectively base line groove depth h = 1.6 2 2.75 3.5 4.8 8.1 9.6.
    Pulley pitch diameter is the theoretical diameter pulley section line position, a bit like the gear pitch circle diameter generally with PD said cylindrical OD indicates general use. Different pitch circle and the outer groove of the conversion formula is not the same, in general we relatively easy to measure the outer pulley, in accordance with the formula to calculate the pitch circle. SPZ: OD = PD 4; SPA: OD = PD 5.5; SPB: OD = PD 7; SPC: OD = PD 9.6. A pulley or the SPA minimum diameter size 80mm, such as less than this size, particularly in the case of high speed, the belt is prone to crack at the bottom of stratification and other illnesses. SPZ belt, ferries can not be less than 63mm.
    Note also that the practices and belt installation tension is too small slippery, too much easy to damage the belt and bearings
