Background

The coupling, also called coupling, is a mechanical part for connecting two shafts (driving shaft and driven shaft) in different mechanisms to rotate together so as to transmit torque, and has the functions of linking, buffering, damping, improving the dynamic performance of the shafting, and the like. In the high-speed and heavy-load power transmission, some couplings have the functions of buffering, damping and improving the dynamic performance of a shaft system. The shaft coupling comprises two halves, and respectively with driving shaft and driven shaft hookup, the inside protective cover that is provided with of shaft coupling because the protective cover generally sets up in the shaft coupling, leads to dismantling comparatively troublesome, and the end cover drawing device among the prior art damages the shaft coupling easily when dismantling the protective cover, causes the waste of resource, and we propose a simple and easy drawing device who dismantles sealed end cover for this reason.
