Between wheel hub, the inwall of rear compacting ring is the lozenges being engaged with the lozenges on rear side of expansion sleeve body outer wall, rear to compress
Outer wall fitting and the inwall of wheel hub of circle, preceding retainer plate is by thread set on power transmission shaft and the rear end face of preceding retainer plate compresses
The front end face of preceding compacting ring, rear retainer plate by thread set on power transmission shaft and rear retainer plate front end face compress after compacting ring
Rear end face, be provided with dismounting screwed hole, preceding fixation on the front end face of described preceding compacting ring and the rear end face of rear compacting ring
It is provided with circle and rear retainer plate and is passed through for connecting bolt and enable bolt to be installed on the front end face of preceding compacting ring with after
The resigning hole in dismounting screwed hole on the rear end face of compacting ring.
Described expansion sleeve body is with opening elastic component.So as to by stretching, be passed to the threaded portion of power transmission shaft
And it is arranged on its installation site.
Described resigning hole is arcuate socket.The arcuate socket can allow for current retainer plate and rear retainer plate to be rotated
When, and the bolt in arcuate socket keeps circumferential position constant, is only axially moved with preceding retainer plate or rear retainer plate.
The utility model has advantages below：
When the utility model is installed, only by rotating preceding retainer plate and rear retainer plate to compress preceding compacting ring and rear compacting ring
The installation that swelling nested structure just is can be completed fixed, easy to operate, and swelling nested structure axiality is high, stable connection, without passing
Keyway is set on moving axis and wheel hub, improves the rigidity of power transmission shaft and wheel hub；Convenient dismounting, preceding it can just be pressed by installation bolt
Collar and rear compacting ring exit attachment structure with the rotation of preceding retainer plate and rear retainer plate.
