The basic situation of the Worm Gear

   Worm gear shaft used to transmit motion between two staggered and motivation. Where between worm and worm gear and rack equivalent plane , the worm has a similar shape with the screw .
   Basic parameters
   Modulus m, pressure angle, worm diameter factor q, lead angle , worm head count, worm gear teeth , addendum coefficient ( take 1 ) and headspace coefficient ( , 0.2 ) . Wherein the modulus number m and the pressure angle is the angle of the worm shaft surface modulus and pressure angle, i.e. the end face of the worm wheel modulus and pressure angle, and are the standard values ​​; worm worm diameter coefficient (q) of the pitch circle diameter of its modulus the ratio of m.
   Properly engaged
    1.Intermediate plane of the worm and worm wheel modulus and the pressure angle are equal, that is the end surface of the worm gear worm modulus equal axial modulus and the standard value ; worm pressure angle of the end face of the worm shaft to be equal to the angle and is the standard surface pressure value, i.e.
== m, ==
   2.When the worm stagger angle too , the need to ensure , and worm and worm helix rotation must be the same .

Worm Gears Units

    Institutional characteristics
    You can get great gear ratio than the compact crossed helical gear mechanism
Two tooth surfaces in line contact , its carrying capacity is much higher than crossed helical gear mechanism
Equivalent helical worm gear drive for multi-tooth meshing , so the smooth transmission, noise is small
With self-locking . When the lead angle of the worm gear teeth meshing between the equivalent of less than the friction angle, with a self-locking mechanism , enabling reverse self-locking, which can only be driven by a worm worm , and not driven by a worm gear worm . Such as heavy machinery used in its self-locking worm gear , the reverse self-locking can play a security role
    Transmission efficiency is low, severe wear . Worm gear transmission , the meshing teeth relative sliding velocity between the large , so friction losses and low efficiency . On the other hand , the relative sliding velocity Ambassador severe tooth wear , severe fever , in order to reduce heat and wear, often using more expensive antifriction material with good abrasion resistance and good lubricating device , and thus higher costs , greater axial force worm

   Attention problems
    Worm lead angle on the worm helix indexing cylinder tangent angle between the end of the worm , and the relationship between the helix angle of the screw , worm spiral angle is large then the transmission efficiency is high, when engagement between the teeth is less than the equivalent friction angle , institutional self-locking.
Coefficient (q) into the worm diameter worm hob in order to limit the number , the pitch diameter of the worm is standardized m is constant , q large then large , the rigidity and strength of the worm shaft increases accordingly ; constant , q smaller the lead angle increases, the transmission efficiency is increased accordingly.
   Worm Head recommended value is 1,2,4,6 , when to take a small value, the transmission ratio, and has a self-locking ; when taking large value, high transmission efficiency .
   Cylindrical gear with different institutions worm worm gear ratio is not equal to the center distance institutions .
   The worm gear worm gear shift determination method , according to the direction of engagement at the point K , the direction ( parallel to the tangent of the helix ), and should be perpendicular to the axis of the worm wheel velocity vector Videos.

   Triangles to determine ; also available " right-handed worm left hand , right hand left worm , four fingers thumb " to determine.
   Application

Introduction of the Timing Gear

   Timing gear is in the mechanical device to complete the relevant control functions for play time scale positioning gear.
   In the internal combustion engine into the exhaust system, such as inside the watch mechanical feature exists for the completion of the partial order relation systems have introduced the timing gear.
   Three timing gear Transmission: chain drive, toothed belt drive, gear drive.
Currently car engine positive and negative toothed belt drive gear are used, this transmission mode has a simple structure, low noise, smooth operation, high driving accuracy, good synchronization, etc., but its strength is low, after very long use and easy aging, tensile deformation or fracture, the housing of the toothed belt, was closed state, inconvenience observe their working conditions. There are a Mitsubishi sedan, without launching symptoms, after oil, circuit troubleshooting, fault still exists, then open the valve chamber cover, find Rocker does not work, determined to be positive when the toothed belt broken.

Spur Gears

    Replace the new, the engine still does not start. Because, once the toothed belt running break, namely stop camshaft, crankshaft rotational inertia of the flywheel or the drive means under the action of inertia continue to rotate a certain angle or laps. At this point the engine does not work, the more serious is the damage to the valve timing, the piston being open position of the top bend valve stem, causing the top bend valve closed lax.
   Therefore, some broken toothed belt of the engine, even more positive re-mark the timing gear, replacement of the timing toothed belt, the engine is still not easy to launch, or barely able to start, but is not working properly, a "tempering" , mufflers, "blasting", lack of motivation, increased noise phenomenon. In this case, only remove the cylinder head, replace the valve, in order to completely restore the technical condition of the engine.

  2.Fixed the coupling feet, moving outside leg, so that the two centerline eccentricity is zero.
  3.After the above two methods is repeated several times, can be in a good pair of coupling state.
  Lifting accessories Couplings find equipment maintenance process is an important task. Alignment principle was simple, but very practical. In the minicomputer pump alignment frequently applied methods are single-table method, two table method and three table method and so on. Either way, there is one common characteristic; horizontal plane than the vertical plane alignment error-prone, repetitive strong, time-consuming, tedious calculations.

Sleeve coupling

  Fixation
  1.An elastic coupling positioning screws: two screws gap 90 º on the fixed shaft locking, traditional fixed manner, since the front end of the screw shaft contact may cause injury or difficult to remove the axis .
  2.Lingsi flexible coupling clamping screws: hexagon bolt is tightened using the power of the slit contraction, while the shaft tightly clamped. In this way fixed and easy removal, and will not cause damage to the axis, is a very common way of fixing.
  3.Resilient Shaft Coupling keyway type fixed: for high torque transmission, in order to prevent axial sliding, usually associated with positioning screw and clamping screws and use.
  4.D-shaped hole fixing flexible coupling: Under normal circumstances, if the motor shaft is to D fonts, screws can not be fixed if the case can be processed into a corresponding coupling hole the size of the D-type motor shaft Kong, with the positioning screw, do not worry about slipping up.
  5.Expansion sleeve fixed: by tightening Lingsi screw coupling end of the four ways oppression swelling fixed set of books for a number of large torque stepper motor and servo motor coupling fixed, such as the expansion sleeve diaphragm Union couplings, expansion sets Plum coupling, bellows coupling expansion sets, expansion sets elastic couplings.

The main characteristics of the Diaphragm Couplings

   Diaphragm coupling 
   Consists of several groups diaphragm (stainless steel sheet) staggered bolt connection with two coupling halves, each diaphragm is made from several pieces stacked set, the diaphragm is divided into different shapes-link and the entire piece. Diaphragm coupling by the elastic deformation of the diaphragm to compensate for the relative displacement of the two axes Union is a strong component of high-performance metal flexible coupling, do not run oil, more compact structure, high strength, long service life , no rotation gap, independent of temperature and oil slicks, with acid and alkali corrosion, suitable for high-temperature, high-speed, a corrosive medium conditions environment shaft drive.
   The main characteristics of the diaphragm couplings 
   Diaphragm couplings can compensate initiative between local and from motives due to manufacturing errors, installation errors, bearing deformation and temperature rise caused by the impact of changes in the axial, radial and angular offsets. Elastic element is a metal diaphragm coupling flexible coupling, which rely on metal diaphragm couplings to connect the main, from motives transfer torque, flexible vibration, no noise, no lubrication advantages of today's alternative teeth couplings and general coupling the ideal product.
   1.Two axes misalignment compensation ability, compared with the gear coupling angular displacement can be doubled in size, radial displacement reaction force is small, flexible large to allow a certain degree of axial, radial and angular displacement.
   2.With a significant damping effect, no noise, no wear and tear.
   3.To adapt to high temperatures (-80 +300) and harsh environments, and can have impact, vibration conditions for safe moving line.
   4.High transmission efficiency up to 99.86%. Particularly suitable for medium and high-power transmission.
   5.Simple structure, light weight, small size, easy assembly and disassembly. Do not have to move the machine to dismantle (mean with intermediate shaft type), without lubrication.
   6.Can accurately transfer speed operation without slip can be used for precision mechanical transmission.

Pin coupling

   Structure 
   Diaphragm coupling at least one diaphragm and two bushings components. Diaphragm is fastened with a pin on the hub generally does not come loose or cause backlash between the diaphragm and the sleeve. Some manufacturers offer two diaphragms, there are provided three of the diaphragm, the middle one or two rigid elements, and then connected on the hub side. Single and double diaphragm coupling membrane coupling the difference is the difference in ability handle various deviations, given its need to bend the diaphragm can be complicated, so do not adapt to the eccentric single diaphragm couplings. The double diaphragm coupling song simultaneously in different directions, in order to compensate for eccentricity.

Structure and Application Industries of Ball Screw Set

    Ball Screw Set, alias ball screw, lead screw, a ball between the nut and the screw between the exercise, the traditional sliding contact screw into the nut rolling contact with the ball and then converted to rotary motion linear motion of the transmission machinery components. Ball screw with high precision, high life expectancy, low pollution and high-speed forward and reverse transmission do and transform transmission and other characteristics, as with the above characteristics, precision ball screw technology industry has become lately and precision machinery industry positioning and measuring systems one of the key components.
   Structure
   Mainly for screw ball screw, nut, ball, mounts, wipers and return pipe posed, according to their different circulatory system more into external circulation, internal circulation, end plugs circulating ball screw.
     The structure of traditional ball screw into the inner loop structure (to circular and elliptical inverter inverter represented) and the outer loop structure (represented by intubation) two kinds. Both structures are also the most commonly used configuration. These two structural performance is no essential difference, but the inner loop structure installation and connection dimensions smaller; outer loop structure installation and connection dimensions larger. Currently, the ball screw structure has more than 10 kinds, but more commonly used are: inner loop structure; outer loop structure; cap structure; cover structure.

SFU Ball Screw Set

    Loop structure within the shape of a variety of reverse, however, is commonly round and oval shape. As round ball reverse channel is shorter, therefore, fluency than oval structure. Now, the best oval structure reverser inner channel structure, the reverse does not pass the ball screw tip, similar to the outer loop structure, therefore, eliminating the screw to the ball tip chamfer error brought reverse affected. However, due to the manufacturing process is relatively complicated, affecting the promotion of such a structure.
   Application Industry

Introduction of Angular Contact Ball Bearings

    Angular contact ball bearings
    Both radial and axial loads. In high speed work. Larger the contact angle, the higher the axial load capacity. High-precision and high-speed bearings usually take the contact angle of 15 degrees. In the axial force, the contact angle will increase.

    Single row angular contact ball bearings can withstand axial load in one direction, the radial load, will cause additional axial force. And the only limit shaft or housing in a direction of axial displacement. Angular contact ball bearing contact angle of 40 degrees, so you can bear large axial load. Angular contact ball bearing non-separation type design, inner and outer rings on both sides of the shoulder uneven. In order to improve the bearing load capacity, which would lower side of the shoulder machined, so that the ball bearings can be put more.
    Double row angular contact ball bearings can withstand greater radial load mainly radial and axial joint load and moment load, limiting both the axis of the axial displacement. Main shaft and the housing for limiting the axial displacement member bidirectional
   Double row angular contact ball bearings, the outer ring is limited between the tiltable, allowing the tilt angle depends on the bearing internal clearance, bearing size, internal design and acting on the bearing force and torque, while the maximum permissible tilt angle should guarantee bearing will not generate excessive additional stress. If the bearing inner and outer angle of inclination between will affect bearing life, also causing precision bearings running down, running noise increases. Double row angular contact ball bearings generally use nylon cage or solid brass cage. Double row angular contact ball bearing installation should pay attention, although bearings can withstand axial load, but if there is one side of the gap when the ball should be careful not to let the main axial load through the notched side of the gutter. Note that the bearing should be used without the ball gap to bear the main load side of the raceway.
    Pairs of double ball bearings
    If paired mounting, making a pair of bearing outer ring is relatively wide side face of wide and narrow side facing the narrow end. This can avoid additional axial force, but also in both directions so that the shaft or housing to limit axial clearance range.
   Its inner and outer ring raceways in the horizontal axis relative displacement, so it can bear radial load and axial load - combined load (single row angular contact ball bearings can withstand axial load in one direction, so often used in pairs).
   Retainers are made of brass, synthetic resins, etc., according to individual bearing features and application conditions.
    More angular contact ball bearings are manufactured abroad, bearing manufacturers, domestic imports of equipment used in such large angular contact ball bearings 3204RS, etc.

Linear Bearing

    Feature
    1. Universally matchable bearings
    Universally matchable bearings are specially processed, when the bearing is installed close to each other, any combination can achieve the established internal clearance or preload, and the average load distribution, without the use of shims or similar devices.
    Pairing bearing applications: When a single bearing load carrying capacity is insufficient (associated with channeling configuration) or when to bear the combined load or effect in both directions of the axial load (with back to back or face to face configuration).
    2. The basic design of the bearing (not as a general with the group), is configured for a single bearing
Basic design of single row angular contact ball bearings are mainly used in each location is only one bearing configuration. Its width and the amount of outstanding ordinary level tolerances. Therefore not suitable for the two single row angular contact ball bearings close to the installation.

Classification of 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.
   Classification
   一、Standard, clearance adjustable linear bearings, linear bearings open type, elongated linear bearings, linear bearings versatility
   二、Flange linear bearings can be divided into: Round Flange, Flange, oval flange type, orientation Round Flange, Flange oriented approach, oriented oval flange, extended round flange type.
   According to specifications standard points:
   Divided into two series that LM and LME series whose code LM series for Asia, Southeast Asia, Japan, Korea, China and so on. In metric sizes as standard, equipped with a linear axis diameter tolerance is generally h7. LME series of multi-used in Europe, the United States, Germany, Italy and other regions. With inch dimensions as the standard, there are metric dimensions, equipped with a linear axis diameter tolerance is generally g6. Two series of structural features, in addition to different sizes, different diameter tolerance, its structure is largely the same.

Linear Bearing

   According to the shape of:
   1. Straight type (shaped like a cylinder, usually with circlip installation for mounting dimensions smaller occasions)
   2. Flange type (end or middle of a mounting flange can be mounted with screws, flange generally divided into round, square and trimming type three)
   3. open type (shape, such as straight, the appearance of an axial slit, the occasion for the need to adjust the gap, and the great opening and a small opening two kinds)
   According to the performance of:
  1. common type (general purpose performance requirements)
  2. Super-type (long-life and high load performance requirements of the occasion)

Deep Groove Ball bearings and Bearing Construction Works

    Deep groove ball bearings are bearing the most common type. Basic deep groove ball bearing is composed of an outer ring, an inner ring, a set of balls and a group holding structure into. Deep groove ball bearing type has two kinds of single and double row deep groove ball structure also split seal and open two structures, open means bearing structure without seal, sealed deep groove ball into dust seal and oil seal. Dust Gland Material steel stamping, just play simple to prevent dust from entering the bearing raceways. Oil-proof seal for the contact, which can effectively prevent the grease within the bearing spillover.
Single row deep groove ball bearing type code 6, double row deep groove ball bearing code is 4. Its structure is simple, easy to use, is the production of the most common, the most widely used class bearings.

   Works
   Deep groove ball bearings mainly take radial load, but also to support radial load and axial load. When the only radial load, the contact angle is zero. When the deep groove ball bearings with a larger radial clearance, the performance with angular contact bearings can bear large axial load, deep groove ball bearing friction coefficient is small, limit speed is also high.

Linear Bearing

  Bearing structure

  Deep groove ball bearing structure is simple, easy to reach compared with other types of high manufacturing precision, so easily into a series of mass production, lower manufacturing costs, the use of extremely common. In addition to basic type deep groove ball bearings, there are a variety of structural variants, such as: Shielded deep groove ball bearings with rubber ring of deep groove ball bearings with snap groove deep groove ball bearings, have installed ball gap large load capacity of deep groove ball bearings, double row deep groove ball bearings.

Concerning the classification of Spherical Ball Bearings

    Spherical Ball Bearings deep groove ball bearing is actually a variant, characterized by its spherical outer diameter surface that can fit into a corresponding concave spherical bearing self-aligning role to play within.
    Spherical bearing priority for applications that require equipment and spare parts for simple cases, such as for agricultural machinery, transportation systems or construction machinery.
     Mainly used to bear radial load mainly radial and axial joint load, generally should not alone bear the axial load, such bearings can be installed separately inner ring (with a whole group of roller and cage) and the outer ring. This kind of bearing does not allow a tilt axis relative to the housing, the radial load appointments will produce additional axial force. This kind of bearing axial clearance of the size of the bearing can work in large, when the axial clearance is too small, the higher temperature; axial clearance is large, bearing easily damaged. Therefore, in the installation and operation of special attention to adjust the bearing axial clearance, if necessary, preloaded mounting, in order to increase the rigidity of the bearing.

Linear Bearing

   Classification
   Spherical plain bearings and shaft in accordance with methods of cooperation to points can be divided into three categories:
    One, with the top wire, spherical ball bearing its code: UC200 Series (light series), UC300 Series (heavy series), and deformation of the product UB (SB) 200 series, if the application of environmental fit smaller, usually pick UC200 series, and vice versa then choose UC300 series. Generally spherical ball bearings on the top wire are two, and its angle of 120 °, with the axis of its co-feature is used when the top wire to the top of the shaft, and then play the fixed effects, but their cooperation Environmental requirements are necessary oscillations are small. The spherical ball bearings throughout the match, widely used in textile machinery, ceramic machinery and other production career.
   Second, spherical ball bearings with taper its code: UK200 series, UK300 series. Such spherical ball bearings diameter 1:12 share taper bore, when the use of co-operation with the use of tight sets, such spherical ball bearings features as: the ability to accept less than with the top wire, spherical ball bearings greater load. As tight sets to cooperate with the inner diameter of the same type than with the top wire, spherical ball bearings [1] is smaller, for example, with the top wire, spherical ball bearings UC209 inner diameter of 45mm, the use of co-axial therewith diameter of 45mm which, were replaced with taper if spherical ball bearings, it can only pick diameter of 45mm adapter sleeve, with 45mm adapter sleeve cooperation with taper outer spherical ball bearings only UK210 up (of course, if fit higher then be able to pick UK310's). Thus, UK210 acceptable fit when so much larger than the UC209's more.
     Three with migraine pain outer spherical ball bearing its code: UEL200 series, UEL300 series, SA200 series. Such spherical ball bearings bearing on one end of the primary characteristics of migraine pain has a certain degree, the same degree of migraine pain migraine pain sets to work with. Such bearings can also be said to be special bearings, because of its prime in the agricultural (harvester, straw, thresher, etc.) on the use of such primary spherical ball bearings used in the layout of beating a strong analogy, migraine pain Layout of cooperation can be useful to cut the strong beat.
