Face-to-face matched angular contact ball bearing and matching method thereof

Abstract

The invention provides a face-to-face matched angular contact ball bearing and a matching method thereof. The face-to-face matched angular contact ball bearing comprises an inner ring. The outer circumferential surface of the inner ring is provided with a first outer groove and a second outer groove. The inner ring is correspondingly sleeved with a first outer ring and a second outer ring. The two outer rings are arranged in a spaced mode in the front-and-back direction. An outer spacer ring is clamped between the two outer rings. The inner circumferential surfaces of the two outer rings are provided with inner grooves. The inner grooves of the two outer rings and the two outer grooves of the inner ring are correspondingly filled with steel balls. The two axial end faces of each outer ring are a wide-side end face and a narrow-side end face respectively. The narrow-side end face of the first outer ring and the narrow-side end face of the second outer ring are oppositely arranged. The narrow-side end face of the first outer ring and the narrow-side end face of the second outer ring make contact with the two axial end faces of the outer spacer ring correspondingly in an abutted fit mode. The axial play of the bearing can be adjusted just by grinding the outer spacer ring, grinding of an inner spacer ring is avoided, the pre-tightening force fitting process of the matched angular contact ball bearing is simplified, and the axial pre-tightening force adjusting time is shortened.

Description

technical field [0001] The invention relates to a face-to-face assembled angular contact ball bearing and an assembled method thereof. Background technique [0002] Angular contact ball bearings are generally used in combination in practical applications, that is, two sets, three sets or even more sets of angular contact ball bearings are used together in a certain configuration. The basic combination method is back-to-back (ie The wide side end faces of the two outer rings are opposite to each other), face-to-face (that is, the narrow side end faces of the two outer rings are opposite to each other), and in series (that is, the narrow side end faces of one outer ring are set opposite to the wide side end faces of the other outer ring). According to the needs of actual working conditions, select bearings with different matching methods. [0003] General face-to-face angular contact ball bearings are mainly formed by combining two sets of angular contact ball bearings in ser...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a face-to-face assembled angular contact ball bearing to solve the technical problem in the prior art that the preloading operation of the face-to-face assembled angular contact ball bearing is relatively cumbersome by using inner and outer spacers for preloading; at the same time, the present invention The invention also provides a method for assembling the above-mentioned face-to-face angular contact ball bearings
