Introduce:

The elastic coupling is a mechanical transmission device used to connect two shafts to rotate together to transmit torque and motion. It is widely used in various fields of national economy. Since it is impossible to align the two connected shafts, the misalignment is caused by factors such as manufacturing errors, installation errors, deformation after loading, and temperature changes of the unit.

Component classification of elastic couplings:

The elastic coupling relies on the elastic deformation of the elastic element to compensate the relative displacement of the two axes, and can also buffer and reduce vibration to avoid resonance. Elastic elements are divided into metal elastic elements and non-metal elastic elements. Metal elastic element couplings include reed couplings, serpentine spring couplings, bellows couplings, diaphragm couplings and diaphragm couplings. Non-metallic elastic element couplings are still widely used, including elastic pin couplings, rubber block couplings, tire couplings, etc. Compared with non-metallic elastic elements, metal elastic elements have higher strength, greater load transfer capacity, no aging problem, long service life, and little influence of temperature, especially suitable for use in continuously operating industrial process power equipment. In particular, the appearance of the diaphragm coupling not only solves many problems of other couplings in the early stage, but also can easily meet the matching with the unit through the adjustment of the design. Therefore, the diaphragm coupling has become the most widely used elastic pin coupling to replace the gear coupling and the non-metallic elastic element coupling, and its performance has become the first product of the turbocompressor unit.

Summarize:

In recent years, it has shown its talents in the transformation of some old units. It is required that the elastic coupling can not only transmit torque and motion, but also absorb the misalignment of the two shafts, and the additional impact on the unit should be as small as possible. The development and evolution of the coupling has always been carried out around this goal.
