Diaphragm Coupling

A Diaphragm Coupling is a flexible mechanical coupling used to transmit torque between two shafts while compensating for misalignment and reducing vibration. It uses a thin, flexible diaphragm (or series of diaphragms) to connect the two shafts, allowing for high torque transmission while maintaining alignment flexibility. This design eliminates the need for traditional bearings, seals, or lubrication, making diaphragm couplings ideal for high-performance, low-maintenance applications.

Key Features:
Flexibility and Misalignment Compensation: The diaphragm(s) allow for angular, radial, and axial misalignment between the connected shafts, helping to reduce strain on the system and improve operational efficiency.
No Lubrication Required: The design of the diaphragm coupling eliminates the need for lubricants, reducing maintenance requirements and the risk of contamination.

Applications:
Pumps and Compressors: To connect shafts while handling torque and vibration.
Electric Motors and Gearboxes: In systems where high power transmission and precision are needed.

Benefits:
Compact Design: They offer a compact, lightweight solution for high-torque applications.
Low Maintenance: With no need for lubrication or bearings, diaphragm couplings are easy to maintain and highly reliable.
