Key Features

Designed for servo and stepper motors
Zero gap between shaft and sleeve connection, suitable for forward and reverse rotation
Low inertia design, optimized for high-speed operation
Diaphragm made of spring steel with excellent fatigue resistance

The double-step double-diaphragm coupling is a high-performance flexible transmission component that connects two sets of diaphragms via an intermediate shaft, specifically engineered to address complex shaft misalignment challenges.

Working Principle

Utilizes elastic three-dimensional deformation generated by dual diaphragm assemblies at both ends of the intermediate shaft to transmit torque from the driving shaft to the driven shaft. Compared to single-diaphragm structures, it can flex simultaneously in multiple directions, more efficiently absorbing combined axial, radial, and angular misalignment while eliminating additional stresses.

Core Advantages

Zero Maintenance: Requires no lubrication or seals
Zero Backlash: No rotational clearance during operation
High Efficiency: Transmission efficiency up to 99.86%
Enhanced Compensation: Dual-step design provides twice the angular displacement capacity of single-diaphragm types
Corrosion Resistant: Resists acid and alkali corrosion
Temperature Range: Withstands extreme environments from -80°C to 300°C
Long Service Life: Exceeds 10 years of reliable operation

Applications

Widely used in heavy-duty equipment such as high-power fans, chemical pumps, and compressors, as well as precision scenarios demanding exceptional transmission accuracy and stability—including aerospace and semiconductor manufacturing applications.
