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.

The shaft coupling structure that uses at present is comparatively simple, and although the processing degree of difficulty is lower, nevertheless when in actual use, because can produce relative rotatory effort between work piece or the mechanism at the during operation, and current shaft coupling adopts integrated into one piece, has leaded to when receiving relative rotatory effort, and shaft coupling itself easily produces deformation, and long-time use leads to the damage of shaft coupling easily, influences production efficiency.
