Sleeve Metal Shaft Coupling Diaphragm Double Clamping Short
GLD Aluminum alloy short double diaphragm clamping coupling
Products Features
Features of Diaphragm Couplings
1. The structure is simple, the volume is small and the disassembly is convenient. The diaphragm coupling of the intermediate shaft type structure can be disassembled without moving the machine;
2. The metal diaphragm coupling can transmit larger torque, can effectively absorb the angle, axial and radial deviations generated when the two shafts are installed, has the characteristics of high precision and zero clearance, and is widely used in high-precision transmission occasions , such as precision electronic manufacturing equipment;
3. The diaphragm coupling has the characteristics of high torque rigidity and is often used in high torque and high-speed motion, such as the output components of energy equipment for high-speed trains;
4. High temperature resistance, acid and alkali corrosion resistance, can be used in high temperature and harsh environments, and can effectively resist shock and vibration during equipment operation.
> 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
