The SDM Aluminum Alloy Double Diaphragm Clamp Coupling For Servo Motor Encoders

Its core structure consists of two stainless steel metal diaphragm groups and an aluminum alloy shaft sleeve located in the middle. It utilizes the elastic deformation of the metal diaphragm to ‌ transmit torque ‌, while effectively ‌ compensate for the axial, radial and angular deviations existing between the two connected shafts. Aluminum alloy material endows it with the advantages of ‌ light weight, small inertia and corrosion resistance ‌, making it highly suitable for high-speed rotation and frequent forward and reverse rotation applications (such as fans, private clothing motors, 3D printing, laser engraving, CNC equipment, etc.), and it also features ‌ maintenance-free, no backlash, long service life and high torsional rigidity ‌. It is an ideal choice for industrial fields that require high-precision, high-reliability and high-efficiency transmission.‌

1.Offset compensation

Axial compensation ‌ : ±0.08 to ±0.9mm, radial compensation ‌ : 0.03 to 0.55mm, angular compensation ‌ : 1 to 1.5°

2.High transmission performance

Zero backlash: The rigid deformation of the diaphragm ensures no rotational clearance, making it suitable for high-precision scenarios such as servo systems.

Wide torque range: selectable from 0.25Nm to 100Nm.

3.High-speed adaptability

Maximum rotational speed up to 10,000 RPM ‌, balance grade up to G6.3 (ISO 1940 standard)

4.Maintenance-free and long-lasting

There are no mechanical friction parts, no lubrication is required, and the service life ‌ > 100,000 hours ‌.

5.Fatigue resistance and corrosion resistance

The stainless steel diaphragm has undergone ‌ pre-stretching treatment ‌, featuring high fatigue strength (cycle times > 10^7). The surface of the aluminum alloy has been anodized, making it resistant to acid and alkali corrosion (meeting IP54 protection).

6.Extreme working condition tolerance

Operating temperature range: ‌-50℃ to +250℃‌, capable of withstanding an instantaneous ‌200% overload torque ‌.

7. Reduce the overall cost

Reduce equipment wear caused by centering errors (such as extending the lifespan of bearings and seals by over 30%), eliminate the need for shutdown maintenance, and save labor and consumable costs.
