How the coupling on the shaft is positioned and fixed

1, clamping screws fixed: the use of hexagonal bolts to tighten the force, so that the slit contraction, the shaft will be tightly clamped, is a commonly used fixing method.

2, D-hole fixed: usually, if the motor's shaft is into a D-shaped, positioning screws can not be fixed in the case of the coupling holes will be treated as corresponding to the size of the motor shaft D-type holes, with the locating screws fixed, do not have to worry about slippage;

3, the keyway type of fixing: suitable for high-torque transmission, in order to prevent axial sliding, usually with the locating screws fixed and clamping screws fixed And use;

4, expansion sleeve fixed: by tightening the coupling end face of the four positioning screws compression account sleeve way expansion fixed, suitable for high torque stepper motors and servo motors coupling fixed;

5, positioning screws fixed: the two positioning screws gap 90 degrees to the fixed shaft locking, the traditional way of fixing, due to the screws contact with the shaft center, which could cause The traditional fixing method, because the front end of the screw is in contact with the shaft center, may cause damage to the coupling shaft center or disassembly difficulties.
