Background

The coupling is also called coupling. Mechanical parts for firmly coupling the driving shaft and the driven shaft in different mechanisms to rotate together and transmitting motion and torque. Sometimes also to couple the shaft with other parts (e.g. gears, pulleys, etc.). Usually, the two halves are combined and fastened to the two shaft ends by a key or a tight fit, and then the two halves are connected in a certain way. The coupling can compensate the offset (including axial offset, radial offset, angular offset or comprehensive offset) between the two shafts due to inaccurate manufacture and installation, deformation or thermal expansion in work and the like; and shock mitigation and absorption. Therefore, from the working principle of the coupler, the working environment of the coupler is very severe and needs to bear great pressure and friction force, so that lubricating oil is often injected into the coupler to reduce friction; however, lubricating oil is often insufficient in work and needs to be supplemented, but the conventional coupler is inconvenient to disassemble and assemble, daily maintenance of the coupler is affected, the coupler is easy to wear and rust, and the service life of the coupler is shortened.
