Product Overview

A coupling is a part that connects two different rotating bodies (motor shaft, ball screw, etc.) and aims at transmitting torque.
The difficulty of assembly adjustment is reduced by absorbing the axis deviation (lateral misalignment, angular misalignment and axial amplitude) between rotating bodies.
And in case of accidental overload, the coupling is destroyed first and the rotating bodies are disconnected to protect the expensive power part and the whole device.

Product Features

■Feature: Despite the axis deviation, it rotates at a constant speed, which is ideal for encoders. Due to the large allowable axial runout, the change of shaft length caused by the change of shaft temperature can be offset.

Example of Use

Precautions

Lateral misalignment, angular misalignment and axial amplitude are all single allowable values. If there are multiple deviations at the same time, the allowable value of each deviation will be reduced to 1/2 of the original value.

Frequently asked question (FAQ)

Question: What is a coupling?: Answer: A coupling is a part that connects two different rotating bodies (motor shaft, ball screw, etc.) and aims at transmitting torque. The load of assembly adjustment is reduced by absorbing the axis deviation (lateral misalignment, angular misalignment and axial amplitude) between rotating bodies. And in case of accidental overload, the coupling is destroyed and the rotating bodies are disconnected to protect the expensive power part and the whole device.
Question: What are the types of MISUMI couplings?: Answer: There are disc type, grooved type, cross type, claw type, bellows type, rigid type and universal joint type.
Question: How to select coupling according to motor?: Answer: Disc type is recommended for servo motors, grooved type is recommended for stepping motors, and cross type is recommended for universal motors.
Question: How to select according to the purpose, environment, working conditions?: Answer: Please refer to the link page for specific instructions. https://www.misumi.com.cn/special/coupling/select/situation/
Question: What kind of coupling should be used when the angular misalignment is very large?: Answer: Please select the universal joint with allowable angular misalignment of 30 degrees. In addition, when grease cannot be applied regularly, use a rubber sleeve to fill grease and use it.
