What are the common ways of fixing the coupling?

When the coupling is used, it needs to be fixed to a certain extent. Only when the coupling is well fixed on the machine can we use it accordingly, so as to ensure that the coupling will not deviate from the accident during construction. Then what are the fixed ways of the coupling?

What are the common ways of fixing the coupling?

1, positioning screw fixed:

The gap between the two positioning screws is 90° to lock the fixed shaft. The traditional fixing method may cause damage to the shaft or disassembly difficulties due to the contact between the front end of the screw and the shaft.

2, clamping screw fixed:

Using the force of the hexagon bolt tightening, the slit shrinks and the shaft is tightly clamped. This method is convenient to fix and disassemble and will not cause damage to the axis, which is a very common fixing method.

3, keyway type fixed:

Suitable for high torque transmission, to prevent axial sliding, usually fixed with positioning screws and clamping screws fixed.

4, D hole fixed:

If the shaft of the motor is a D-shaped positioning screw that 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 fixed with the positioning screw, there is no need to worry about slipping.

5, expansion sleeve fixed:

By tightening the four positioning screws on the end face of the coupling, it is suitable for the coupling and fixing of some stepper motors and servo motors with high torque, such as the expansion diaphragm coupling, the expansion box coupling, the expansion bellows coupling, etc.

The above is about the coupling in some ways when fixed, in the use of relevant parts, we must do a good job of the corresponding fixed work, so as to ensure that our entire work safety is guaranteed, and for the use of parts we should also pay attention to according to certain standards.
