Briefly introduce the fixing method of the coupling
2021-11-18 10:47:13

There are many ways to fix the coupling. Today we will explain what is included in the concrete. Let's take a look at it:

D hole fixing:

Under normal circumstances, if the shaft of the motor is D-shaped, if the positioning screw cannot be fixed, the hole of the coupling can be processed into a D-shaped hole corresponding to the size of the motor shaft, and the positioning screw is fixed, so there is no need to worry about slipping. It is.

Clamping screw fixing:

Use the force of tightening with a hexagon socket head bolt to shrink the slit and hold the shaft tightly. This method is convenient for fixing and dismounting, and does not cause damage to the shaft center. It is a very common fixing method.

Keyway type fixing:

Suitable for high-torque transmissions, in order to prevent axial sliding, it is usually fixed with the set screw and the clamping screw.

Positioning screw fixing:

The two positioning screw gaps 90o lock the fixed shaft. The traditional fixing method may cause damage or disassembly of the shaft due to the contact of the front end of the screw with the shaft.

Expansion sleeve fixed:

It is suitable for the connection and fixing of some stepping motor and servo motor with large torque, such as expansion sleeve diaphragm coupling and expansion sleeve plum coupling. , expansion sleeve bellows coupling, etc.
