Aluminum Shaft Coupling 25mm 35mm 50mm 60mm Double Diaphragm Clamping
GL Aluminum alloy double diaphragm clamping coupling
Products Features
Shaft Coupling is a mechanical component used to connect the driving shaft and driven shaft in different mechanisms to rotate together and transmit motion and torque. In addition to transmitting motion, the coupling can also compensate the offset (including axial offset, radial offset, angular offset or comprehensive offset) between the two shafts due to inaccurate manufacturing and installation, deformation or thermal expansion during operation, mitigate impact and vibration absorption, and play the role of overload protection to achieve stable motion transmission.
The following is the advantage of GL Aluminum alloy double diaphragm clamping shaft couping,
> High torque rigidity, can accurately control the rotation of the shaft, can carry out high-precision control
> Designed for servo and stepping motor
> No gap between the shaft and sleeve connection, general for positive and negative rotation
> Low inertia, suitable for high speed operation
> The diaphragm is made of spring steel with excellent fatigue resistance
> Fastening method of clamping screw
