Diaphragm coupling drive structure performance

A diaphragm coupling is a mechanical component that connects the driving part and the follower mechanism together to rotate and transfer energy and motion. It has no lubrication, long service life, and great compensation ability. It passes through the flexible steel sheet to transfer torque, with angular, axial, radial displacement compensation ability and damping effect.

Diaphragm coupling diaphragm assembly is convenient, and no lubrication, can be used in a variety of working conditions. The coupling transmission part is favored by construction machinery and compression extension machinery because of its use function. Although the diaphragm coupling is durable, it will also cause failure or even scrap due to various reasons, so it is of great significance to study the cause of failure. Diaphragm failure is the primary form of coupling failure. Coupling adopts the form of tooth top positioning. Top open space selection. At static state, the floating outer gear sleeve has a bias pain relative to the rotating center of the shaft. When rotating up at high speed, in the absence of torque transmission, the floating outer tooth extraction sleeve under the action of centrifugal force will be partial operation, and partial load to complete the stable operation needs to transfer enough torque. Because the tip positioning is generally small, the lifting of the external gear sleeve can be biased less, the centrifugal force is small, and the required torque for stable operation is small. In order to make the gear coupling run stably, small torque is required when the high speed rotation, to confirm the bias caused by the open space of the top of the gear standard, it is also necessary to consider the difference between the ring and the outer gear shaft sleeve caused by the high speed rotation of the radial expansion.

If the diaphragm coupling is transmitted under normal working conditions, the torque is much larger than the small force required for R constant operation, and after transferring the torque, it can complete self-centering and reach stable operation. The connecting shaft of buoyancy is planned into a hollow shaft to reduce weight and improve the stability of buoyancy parts. The gear teeth are positioned at the top of the tooth to reduce the top clearance. Dynamic balancing accuracy requires the improvement of action balance by separating the output shaft and gas turbine rotating shaft installed in the accessory gear box.
