technical field

The utility model relates to the technical field of shaft couplings, in particular to an elastic shaft coupling which is convenient for disassembling and assembling an elastic body.

A shaft is a mechanical part used to connect two shafts (a driving shaft and a driven shaft) in different mechanisms to rotate together to transmit torque. In high-speed and heavy-duty power transmission, some couplings also have the functions of buffering, damping and improving the dynamic performance of the shafting.
