Alignment and Fixation Methods of Resilient Shaft Coupling

   Resilient Shaft Coupling usually made of metal rod wire cut from the commonly used materials are aluminum, stainless steel, plastic. Resilient Shaft Coupling using a parallel or spiral grooving system to adapt to a variety of bias and precision torque transmission. Resilient Shaft Coupling usually have good performance and have the price advantage, in many stepper, servo systems practical applications, flexible coupling is the preferred product. One-piece design allows flexible coupling to achieve a zero clearance to pass torque and no maintenance advantages. Flexible coupling mainly in the following two basic series: spiral groove and parallel groove.
   Alignment method
   1.Fixed lifting accessories motor side coupling legs outside, move inside foot until motor and pump eccentric to the center line of zero. To ensure that the motor is not any activity in the fixed motor side foot after the other side of the top wire to withstand use.
  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.

  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.

Installation and Maintenance issues and installation and removal methods of Diaphragm Coupling

   Installation Issues
   1.Products with diaphragm edge, there may be injury, it is recommended to wear thick gloves when installing.
   2.Please install the coupling guard and other peripheral devices to ensure safety.
   3.Installation axis deviation exceeds allowable value, the coupling may deform causing damage or shorten the life.
   4.Coupling allowable axial deviation including radial, angular and axial deviation. Installation, make adjustments to ensure that the axis deviation in the corresponding product directory under the permissible value range.
  5.When multiple deviations occur simultaneously, the corresponding allowable value should be halved.
  6.Order to extend the service life of the coupling, it is recommended to set the allowable axial offset of 1/3 or less.
  7.Mounting shaft is inserted before tightening the screws, otherwise it will cause deform the coupling. Tighten the screws, use a torque wrench, do not use attachments other than the screws.
  8.During operation if abnormal sounds, immediately stop operation, and installation accuracy, loose screws, etc. were examined. Recommends the screw after installation adhesive topcoat appearance and increase protection.

   Installation and removal
  1.The mounting shaft surface dust wipe clean dirty, wipe a thin layer of oil peers or lubricants.
  2.Lingsi the coupling hole cleaner will clean, wipe the oil or lubricant.
  3.Insert the Lingsi mounting shaft couplings; such as aperture is tight, taking care to avoid hitting with a hammer or hard metal installation.
  4.Positioning is complete, press the diagonal direction, with the torque wrench (tightening torque specified 1/4) Gently tighten the screws.
  5.Intensify (specified tightening torque 1/2) Repeat step 4 to complete action.
  6.Press the specified tightening torques Tightening torques fasten.
  7.Finally, press the circumferential direction successively tighten the screws.
  8.When removing the device completely stopped under the state; sequentially loosen the lock screw.

   Maintenance
  1.The installation should be cleaned two shaft end, check the mouth, such as face keyway with the situation;
  2.Diaphragm couplings installed, the normal operation of a class, you must check all the screws, if found loose, must be tightened, so that repeated several classes to ensure that no loose;
  3.The diaphragm at high speed in order to prevent fretting wear occurs, leading to micro-cracking diaphragm bolt holes and damage, can be applied between the diaphragm with a solid lubricant such as molybdenum disulfide or antifriction coating film surface layer processing;
  4.Diaphragm couplings should avoid long-term use and operation of overloading the accident;
  5.Diaphragm coupling operation at work, you should always check whether a diaphragm coupling anomalies, anomalies occur if necessary and enter maintenance;
  6.Diaphragm coupling may be due to the operation of the diaphragm couplings and equipment accidents cause personal in all venues must take appropriate safety precautions.
