Technical Field

The utility model relates to a shaft coupling technical field specifically is a high damping shaft coupling with elastic block.

Background

Mechanical parts for coupling two shafts (driving shaft and driven shaft) in different mechanisms to rotate together to transmit torque. In the high-speed heavy-load power transmission, some couplings also have the functions of buffering and damping and improving the dynamic performance of a shaft system. The coupling consists of two halves which are respectively connected with the driving shaft and the driven shaft. Generally, a power machine is connected with a working machine by means of a coupling. The coupler belongs to the field of mechanical universal parts and is a mechanical part used for connecting two shafts (a driving shaft and a driven shaft) in different mechanisms to rotate together so as to transmit torque. In the high-speed heavy-load power transmission, some couplings also have the functions of buffering and damping and improving the dynamic performance of a shaft system. The coupling consists of two halves which are respectively connected with the driving shaft and the driven shaft.
