Coupling information:
The main functions of the coupling are:
Connect the drive shaft of a motor, etc., and the driven shaft, such as a ball screw, to transmit power.
The installation error of the shaft center of the drive shaft and the driven shaft is allowable.
Absorbs the shock and vibration of the device.
Improve device performance.
1. Connect drive shaft and driven shaft, transmit power
The biggest function of the coupling is to connect a drive shaft such as a motor and a driven shaft such as a ball screw, and transmit the power of the motor to the driven shaft.
There are many ways to connect with the shaft, such as the "fixed set screw type" that directly presses the screw on the shaft, the "clamping type" that uses frictional force to connect, and the "expansion sleeve type" that uses the wedge effect.
2. The installation error of the shaft center of the drive shaft and the driven shaft is allowable.
The misalignment of the drive shaft and the driven shaft is called error. There are three types of errors: eccentricity, declination, and axial deviation (axis direction deviation). These may cause vibration, noise, uneven bearing wear and other causes of device failure, so they should be minimized as much as possible.
However, it is very difficult to control the error adjustment to zero when assembling the device.
Couplings have the function of allowing tolerance adjustments that cannot be fully adjusted during assembly.
3. Absorbs the shock and vibration of the device.
Elastomers, etc. are embedded in the plum-shaped coupling as an intermediate part, and it is a coupling that can absorb shock and vibration.
4. Improve the performance of the device.
Depending on the type of coupling, in addition to the functions mentioned above, some can also improve the performance of the device.
