The elastic pin coupling is fixed with keyway for high torque

　　due toCouplingThe rubber block in the middle will be elastically deformed when transmitting torque, so that the coaxiality between the motor shaft and the worm shaft can be automatically adjusted within a certain range, so it allows a larger concentricity (tolerance 0.1mm) during installation, Make installation and maintenance easy, at the same time,Flexible couplingIt has a mitigation effect on the vibration in the transmission.

　　1. Elastic coupling keyway type fixation: suitable for high torque transmission. In order to prevent axial sliding, it is usually used together with set screw fixation and clamping screw fixation.

　　2. Elastic coupling clamping screw fixation: Utilize the tightening force of hexagon socket bolts 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, and is a very common fixing method.

　　3. Expansion sleeve fixing: tighten the four positioning screws on the end face of the Lingsi coupling to compress the account cover. It is suitable for the connection and fixation of some stepping motors and servo motors with large torque, such as expansion sleeve diaphragm couplings. Shaft, expansion sleevePlum coupling, Expansion sleeve bellows coupling, expansion sleeve elastic coupling, etc.

　　4. Elastic coupling 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 corresponding to the size of the motor shaft. The hole is fixed with the positioning screw, so there is no need to worry about slipping.

　　5. Elastic coupling positioning screw fixation: The two positioning 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.
