Reasons for the centrifugal force of the outer edge of the coupling and the deformation of the elastic element

The following is the XINLAN coupling analysis:

CouplingThe allowable speed range is determined by calculation based on the allowable linear speed of different materials of the coupling and the maximum outer edge size.The allowable speed range of couplings of different materials, varieties and specifications is different. Changing the material of the coupling can increase the allowable speed range of the coupling. The allowable speed for steel is greater than the allowable speed for cast iron.
For couplings used under working conditions of n>5000r/min, influencing factors such as the centrifugal force on the outer edge of the coupling and the deformation of elastic elements should be considered, and should be dynamically balanced.Non-metallic elastic element elastic couplings should not be used at high speeds. When the elastic elements are deformed at high speeds, high-precision flexible couplings should be selected. At present, the couplings used for high-speed abroad are nothing more than diaphragm couplings and High-precision drum gear coupling.

The two shafts connected by the coupling are deformed due to manufacturing errors, assembly errors, installation errors, shaft load, base deformation, bearing damage, temperature changes (thermal expansion, cold contraction), relative movement between components, etc. Relative displacement
