Keyway flange diaphragm coupling

Keyway flange diaphragm couplingRelying on the elastic deformation of the diaphragm to compensate for the relative displacement of the connected two shafts, it is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, has a compact structure, has a long service life, no rotation gap, and is not subject to temperature. And oil pollution.

The keyway flange diaphragm coupling is very delicate, the diaphragm has good torque rigidity, and it is easy to be damaged if it is misused in use or not installed correctly.Therefore, the deviation is very large within the tolerance range of the normal operation of the coupling.In order to prevent the fretting of the diaphragm during high-speed operation, causing microcracks and damage to the bolt holes of the diaphragm, a solid lubricant such as molybdenum disulfide can be applied between the diaphragms or the surface of the diaphragm can be treated with a wear-reducing coating , The keyway diaphragm coupling is often used in numerical control equipment.

Keyway flangeDiaphragm couplingIt has the characteristics of acid and alkali resistance. It is suitable for high temperature, high speed, and corrosive medium shafting transmission. It is widely used for shafting transmission of various mechanical devices, such as water pumps (especially high-power, chemical pumps), Fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), high-speed power transmission systems of ships, after being dynamically balanced, have been applied to high-speed transmission shafts. More common.

Features of keyway flange diaphragm coupling:

1. Diaphragm coupling with keyway connection.

2. Zero backlash, convenient for disassembly and assembly.

3. The characteristics of clockwise and counterclockwise rotation are the same.

4. High sensitivity and large transmission torque.

5. The stainless steel diaphragm compensates radial, angular and axial deviations.

6. It is often used for the connection of servo motors and stepping motors.
