Coupling Introduction？

Coupling is a key component that connects two axes in a mechanical transmission system. Its main functions include:

Transmit torque and rotation
Transmit the torque and rotation of the driving end to the driven end
Compensate for axial, radial, and angular deviations
Allow certain deviations between bearings to reduce stress and vibration
Isolate the driving end and the driven end
Prevent vibration and impact of one end from affecting the other end
Common types of couplings are:

Rigid coupling
Connects two shafts by direct bolts or welding
Simple structure and high transmission accuracy
Elastic coupling
Uses elastic elements such as springs, rubber, etc. for connection
Can absorb vibration and impact, protect bearings and motors
Universal joint coupling
Uses cross shaft and cross-bearing for connection
Can compensate for certain angle deviations
Hydraulic coupling
Realizes torque transmission through liquid coupling
Used for high-power transmission, can isolate vibration
The selection of couplings needs to consider the following factors:

Transmission power and torque
Allowable axial, radial, and angular deviations
Working environment (temperature, humidity, corrosiveness, etc.)
Installation space restrictions
Cost and reliability requirements
Correct selection and installation are the keys to ensuring long-term and reliable operation of the coupling. At the same time, regular inspection of the status of the coupling and timely replacement of worn parts are also necessary maintenance measures.
