Frequently Asked Questions about This Product
1. How should the body made of different materials be selected?
The body materials of diaphragm couplings mainly include aluminum alloy, stainless steel and carbon steel. The aluminum alloy material is suitable for working conditions with stable operation and slight impacts, having small rigidity and moment of inertia.
Stainless steel and carbon steel are suitable for working conditions with relatively large impacts, with large rigidity and moment of inertia. Among them, stainless steel is applicable to working conditions with high requirements for rust prevention and corrosion resistance.
2. What is the general service life of diaphragm couplings?
The service life of couplings is closely related to the working conditions, including environmental factors, load conditions, maintenance conditions and working frequency.
Under normal usage conditions, the coupling can transmit more than one million times of dynamic loads throughout its life cycle.
3. What are the reasons for diaphragm fracture?
The concentricity of the installation shafts exceeds the tolerance range of the selected coupling.
There is an instantaneous overload torque that exceeds the maximum torque of the coupling.
The torque of the selected coupling does not meet the requirements of the working conditions.
When installing the coupling, the shaft exceeds the position of the diaphragm, resulting in the diaphragm being squeezed by the shaft and fractured during operation.
4. Can diaphragm couplings withstand axial forces?
Although diaphragm couplings are flexible couplings and can tolerate a certain amount of axial deviation, the couplings are mainly used for torque transmission. When subjected to axial forces while transmitting torque, the torque transmission performance of the diaphragm will be greatly weakened, affecting the service life of the coupling.
