[0002] A tapered roller bearing is a kind of separated rolling bearing, mainly composed of an inner ring, an outer ring, tapered rollers and a cage. The outer surface of the inner ring and the inner surface of the outer ring are designed as tapered raceways. The tapered rollers are evenly distributed between the inner and outer raceways through the window holes of the cage. The function of the cage is to accurately guide and constrain the circumferential spacing of the rollers to avoid mutual collision. During assembly, the tapered rollers are first embedded in the window holes of the cage according to the process requirements, then the inner ring is pressed into the assembly along the axial direction, the cage is pushed axially by a tool to make the inner ring raceway fit the rollers, and finally the outer ring is axially aligned and fitted with the inner assembly to complete the overall assembly of the bearing.

[0003] In the traditional assembly process of tapered roller bearings, the bearing needs to be lubricated. When the tapered roller bearing is lubricated by smearing lubricating oil, it is difficult to smear lubricating agent in the gap and angle due to the small internal gap of the bearing and the dense distribution of the rollers, and the lubrication efficiency of the tapered roller bearing is low. In the prior art, the rollers are installed in the cage by a roller injection machine, and the installation accuracy of the rollers cannot be guaranteed, which affects the assembly speed of the inner ring. The bearing assembly can only be performed in a single step sequentially, and it is not convenient to combine multiple steps, resulting in the devices of other steps being in a shutdown waiting state when a single step is performed, and the waiting time cannot be reasonably utilized to further improve the assembly efficiency of the bearing.
