Single Diaphragm Coupling is a high-performance flexible coupling that uses the elastic deformation of a single stainless steel diaphragm to transmit torque and compensate for axial, angular and a small amount of radial deviation. It has the characteristics of no gap, no lubrication, light weight, and low moment of inertia. It is suitable for high-speed and high-precision transmission occasions, such as machine tool spindles, servo systems and pump equipment. It has a compact structure and is easy to install. It can effectively reduce mechanical vibration and extend the service life of the system.

Q: What is a Single Diaphragm Coupling and how does it work?
A: It uses a thin, flexible metal diaphragm that elastically deforms to transmit torque while accommodating misalignment. It connects shafts with minimal backlash and allows axial, angular, and radial compensation, ensuring precise and smooth power transmission.
Q: What types of misalignment can this coupling compensate for?
A: It can compensate for axial displacement, angular misalignment, and limited radial offset, reducing stress on connected equipment and preventing premature wear.
Q: What materials are typically used in these couplings?
A: The diaphragm is made from high-strength stainless steel with excellent fatigue resistance, while the hubs are made from alloy steel or aluminum alloys to balance strength and weight.
