A tandem assembled angular contact ball bearing and its assembly method

Abstract

The invention relates to a tandem angular contact ball bearing and an assembling method thereof. The tandem angular contact ball bearing includes an inner ring axially extending along the front and rear directions, and the outer peripheral surface of the inner ring is provided with a first outer groove and In the second outer channel, the first outer ring and the second outer ring are correspondingly set outside the inner ring. There is an inner groove on the peripheral surface, and 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 are respectively wide-side end faces and narrow-side end faces , the wide side end face of the first outer ring is arranged opposite to the narrow side end face of the second outer ring, the wide side end face of the first outer ring and the narrow side end face of the second outer ring correspond to the axial end faces of the outer spacer Contact top press fit. The overall structure of the tandem matched angular contact ball bearing is simple, and the axial clearance of the entire bearing can be adjusted only by grinding and adjusting the outer spacer, and the preloading operation is simple.

Description

technical field [0001] The invention relates to a tandem 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] The general series matching angular contact ball bearing is mainly formed by combining two sets of angular contact ball bearings in seri...
