Flexible Single Diaphragm Coupling Double Step

GST Aluminum Alloy Double Step Single Diaphragm Clamp Type Coupling

Products Features 

Coupling is a mechanical part used to connect two shafts (driving shaft and driven shaft) in different mechanisms to rotate together to transmit torque. In high-speed and heavy-duty power transmission, some couplings also have the functions of cushioning, damping and improving the dynamic performance of shafting.

Diaphragm coupling belongs to metal flexible coupling, which is a transmission device that uses metal elastic diaphragm as a flexible element to transmit torque. Its main features are: large transmission torque capacity, deformation of the diaphragm to absorb the misalignment of the unit, no relative movement between parts, no wear, no noise, long vibration reduction life, and no need for lubrication. The torsional stiffness and critical speed can be adjusted by changing the outer diameter or wall thickness of the intermediate section, thereby improving the torsional vibration characteristics of the unit.

The diaphragm coupling consists of at least one diaphragm and two shaft sleeves. The diaphragm is pinned to the bushing generally without loosening or causing backlash between the diaphragm and the bushing. Some manufacturers offer two diaphragms, while others offer three diaphragms, with one or two rigid elements in the middle, and the two sides are attached to the bushing. The difference between the single-diaphragm coupling and the double-diaphragm coupling is the ability to handle various deviations. Since it requires the complex bending of the diaphragm, the single-diaphragm coupling is not suitable for eccentricity. The double-diaphragm coupling can be bent in different directions at the same time to compensate for eccentricity
