1. Locating screw fixation: The two locating screws have a gap of 90° to lock the fixed shaft. In the traditional fixing method, because the front end of the screw contacts the shaft, it may cause damage to the shaft or difficulty in disassembly.
2. Clamping screw fixation: Utilize the tightening force of the hexagon socket bolt to shrink the slit and clamp the shaft tightly.This method is convenient to fix and disassemble, and will not cause damage to the shaft, so it is a very common fixing method.
3. Keyway type fixation: suitable for high-torque transmission. In order to prevent axial sliding, it is usually used together with positioning screws and clamping screws.
4. D-shaped hole fixing: Normally, if the motor shaft is D-shaped, if the positioning screw cannot be fixed, the coupling hole can be processed into a D-shaped hole corresponding to the size of the motor shaft, and the positioning is coordinated Screw fixed, no need to worry about slipping.
5. Expansion sleeve fixation: The tent is compressed and fixed by tightening the four positioning screws on the end of the coupling. It is suitable for the connection and fixation of some stepping motors and servo motors with large torque, such as expansion sleeve diaphragm couplings. , Expansion sleeve plum coupling, expansion sleeve bellows coupling, etc.
