Bearing rolling body interference assembly device

The invention discloses a bearing rolling body interference assembly device, and relates to the technical field of bearing rolling body assembly. The problems that according to an existing bearing rolling body interference assembly mode, time and labor are wasted in operation, roller installation is not accurate, and a rolling body and a raceway collide with each other are solved. The lower portion of a hollow gear shaft is sleeved with a tapered roller bearing, a workbench is installed at the upper end of the hollow gear shaft, and a first step plane, a second step plane and a third step plane which are used for containing a bearing outer ring, a retainer and a rolling body to be assembled respectively are sequentially machined on the upper surface of the workbench from outside to inside in the circumferential direction. A check block is arranged on the outer side of the bearing outer ring, an ejector block is arranged above an inner hole of the workbench and corresponds to a rolling body to be assembled, th
