Introduction to the characteristics of flexible couplings with inelastic elements
The flexible coupling produced by Botou XINLAN Coupling Factory: It has the ability to compensate for the relative offset of the axis of the connected two shafts. The maximum compensation amount varies with different models.Where the coaxiality of the connected two shafts is not easy to guarantee, flexible couplings should be used.
The flexible coupling without elastic elements has a large load-bearing capacity, but it does not have the performance of buffering and damping. It will have impact and noise at high speed or unstable rotation or forward and reverse rotation.It is suitable for occasions with low speed, medium load and stable speed.
Flexible couplings with non-elastic elements have good cushioning and vibration reduction performance when the speed is unstable; only due to the low strength of non-metallic (rubber, nylon, etc.) elastic elements, short life, small load-bearing capacity and high resistance to low temperature performance Poor, so it is now used for high-speed, light-load and normal temperature occasions.
The flexible coupling of the metal elastic element not only has good cushioning and vibration reduction performance, but also has a large bearing capacity.Suitable for large speed and load changes and high or low temperature occasions.
2. Common types, structures and characteristics of flexible couplings
(1) Oldham coupling: It is a flexible coupling without elastic elements, which has a good ability to compensate the relative deviation of the two shafts and has a large load-bearing capacity; but it does not have the performance of buffering and damping.It is suitable for occasions where the shaft has high rigidity, medium load, low speed and no severe impact.
2) Gear coupling: It is a coupling without elastic elements, which has a good ability to compensate the relative deviation of the two shafts and has a large load-bearing capacity; but it does not have buffering and damping performance, the gear meshing part needs to be lubricated, and the structure is complex. The cost is high.Suitable for medium load and low speed occasions.
(3) Roller chain coupling: It is also a flexible coupling without elastic elements.It has a simple structure, convenient assembly and disassembly, high efficiency, and has a certain ability to compensate the relative deviation of the two axes; but it has impact noise at high speed, unstable rotation or forward and reverse rotation, does not have the ability to buffer vibration, and cannot withstand the axial direction. Power and so on.It is suitable for working in harsh environments such as high temperature, heavy sinking, oily dirt, and humidity.
