Bauer couplings use parallel or spiral grooving systems to accommodate a wide range of deviations and deliver torque precisely.
Bauer couplings usually have good performance and price advantage. In many stepper, servo system applications, Bauer couplings are the first choice.
The all-in-one design enables the Bauer coupling to transfer torque without clearance and require no maintenance. There are two basic series of Bauer couplings: spiral groove type and parallel groove type.
1. Fixation by Bauer coupling set screw: The gap between the two set screws is 90º to lock the fixed shaft. The traditional fixing method may cause damage to the shaft or difficulty in disassembly due to the contact between the front end of the screw and the shaft.
2. Fixation by Bauer coupling clamping screw: Use the tightening force of the inner hexagon bolt to shrink the slit and hold the shaft tightly. This method is convenient to fix and disassemble, and will not cause damage to the shaft of the Bauer coupling. It is a very common fixing method.
3. Fixation by Bauer coupling keyway type: It is suitable for high torque transmission, in order to prevent axial sliding, and it is usually used together with positioning screw fixing and clamping screw fixing.
4. Fixation by Bauer coupling D-shaped hole: Usually, if the shaft of the motor is D-shaped and the positioning screw cannot be fixed, the hole of the coupling can be processed into a D-shaped hole corresponding to the size of the motor shaft. With the positioning screws, you don't have to worry about slipping.
5. Fixation by expansion sleeve: By tightening the four positioning screws on the end face of the Bauer coupling, the compression sleeve is tightened and fixed, which is suitable for the connection and fixing of some stepper motors and servo motors with large torque.
Such as expansion sleeve diaphragm coupling, expansion sleeve plum blossom coupling, expansion sleeve bellows coupling, expansion sleeve elastic coupling, etc.
1. The elastic sleeve pin lug coupling relies on the locking force of the pin group to generate frictional torque with the contact surface, and compress the rubber elastic sleeve to transmit the torque.
It is suitable for small and medium power system shaft transmission with good mounting base rigidity, high centering accuracy, small impact load and low vibration damping requirements.
2. The elastic sleeve is compressed and deformed during operation. Because the thickness of the elastic sleeve is thin, the volume is small, and the elastic deformation is limited, although the elastic sleeve pin lug coupling can compensate for the axial displacement and elasticity, the compensation amount for the axial displacement is less. The elasticity is weak.
3. The structure of the elastic sleeve pin lug coupling is relatively simple, easy to manufacture, no lubrication, no need to be bonded with metal oxidation, the convenient replacement of the elastic sleeve, no need to move the half coupling and has a certain compensation for the relative offset of two shafts and shock absorption buffer performance.
