The main fixing forms of couplings include elastic coupling positioning screws, clamping screws, keyway types, letter holes, and expansion sleeve fixing. Below, Shanghai Maidong, a tire coupling company, will analyze these fixing methods.

1. Coupling positioning screw fixation:

The gap between the two positioning screws is necessary for locking the fixed shaft. Traditional fixing methods may cause damage to the shaft or make it difficult to disassemble due to the contact between the front end of the screw and the shaft center.

2. Clamping screw fixation:

Use the force of tightening the hexagonal socket screw to shrink the slit and tightly clamp the axis. This form of fixation and disassembly is convenient and will not cause damage to the axis, making it a very common form of fixation.

3. Keyway type fixation:

To adapt to high torque transmission and avoid axial sliding, it is generally fixed with positioning screws and clamping screws.

4. Character hole fixation:

In general, if the motor shaft is in a straight shape and the positioning screw cannot be fixed, we can dispose of the coupling hole as a corresponding motor shaft volume hole, which is suitable for fixing with positioning screws, so we don't have to worry about slipping out.

5. Tightening sleeve fixation:

We can use the method of tightening the four positioning screws on the end face of the coupling to compress the sleeve for expansion and fixation. This method is more suitable for connecting and fixing stepper motors and servo motors with high torsional forces, such as expansion sleeve diaphragm couplings and expansion sleeve plum blossom couplings.
