Description

Technical Field

[0001] The invention relates to the field of tapered roller bearing machining, and in particular to a tapered roller bearing pairing mechanism. Background Art

[0002] Bearing pairing is to determine the thickness of the inner spacer between a pair of tapered roller bearings according to the required clearance. The current tapered roller bearing pairing technology determines whether the clearance value is reasonable by the circumferential force required when the inner ring of a pair of tapered roller bearings rotates relative to the outer ring at a constant speed. First, the thickness difference between the inner and outer rings of a single tapered roller bearing is measured one by one, and the spacers of two tapered roller bearings are pre-matched according to the measurement data. Then, the two tapered roller bearings and the spacers are mounted on the shaft. According to the force required to rotate the outer ring, it is determined whether the clearance value of the paired tapered roller bearings meets the required value. It is necessary to undergo multiple tests to determine whether the clearance value meets the requirements, that is, the thickness of the inner spacer between the tapered roller bearings is repeatedly ground to achieve the best clearance value.
