A series assembled double row angular contact ball bearing and its assembly method

Abstract

The invention relates to a tandem assembled double-row angular contact ball bearing and an assembly method thereof, comprising an inner ring axially extending along the front-rear direction, and first outer grooves arranged at intervals along the front-rear direction on the outer peripheral surface of the inner ring The first outer ring corresponding to the first outer channel and the second outer ring corresponding to the second outer channel are sleeved outside the inner ring, and the two outer rings are arranged in sequence along the front and rear directions and topped Pressure contact fit, the inner peripheral surfaces of the two outer rings have inner grooves, the inner grooves of the two outer rings and the two outer grooves of the inner ring are filled with steel balls, and the two axial end faces of each outer ring They are wide-side end faces and narrow-side end faces respectively, and the narrow-side end faces of the first outer ring and the wide-side end faces of the second outer ring are correspondingly contacted and press-fitted. The overall structure of the tandem-matched double-row angular contact ball bearing is simple. Since the inner and outer spacers are eliminated, the grinding of the inner and outer spacers is avoided, the preload repair process of the combined angular contact ball bearing is simplified, and the adjustment of the axial preload is saved. time.

Description

technical field [0001] The invention relates to a series assembled double-row 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] The general series matching angular contact ball bearing is mainly formed by combining two sets of angular contact ball beari...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a tandem assembled double-row angular contact ball bearing to solve the technical problem in the prior art that the preloading operation of the tandem assembled angular contact ball bearing which uses inner and outer spacers for preloading is relatively cumbersome; At the same time, the present invention also provides an assembly method for assembling the above-mentioned tandem-type double-row angular contact ball bearings
