Face-to-face type assembled double-row angular contact ball bearing and assembling method thereof

Abstract

The invention provides a face-to-face type assembled double-row angular contact ball bearing and an assembling method thereof. The face-to-face type assembled double-row angular contact ball bearing comprises an inner ring, and a first outer channel and a second outer channel are formed in the peripheral face of the inner ring. The inner ring is correspondingly sleeved with a first outer ring and a second outer ring, the two outer rings are sequentially arranged in the front-back direction and are in jack-pressing contact fit, inner channels are formed in the inner circumferential faces of the two outer rings, and the inner channels of the two outer rings and the two outer channels of the inner ring are correspondingly filled with steel balls. The two axial end faces of each outer ring comprises a wide-edge end face and a narrow-edge end face, and the narrow-edge end face of the first outer ring is in corresponding contact and jack-pressing fit with the narrow-edge end face of the second outer ring. Due to the fact that an inner spacer ring and an outer spacer ring are omitted, the inner spacer ring and the outer spacer ring are prevented from being ground, a pretightening force repairing process for assembling the angular contact ball bearing is simplified, axial pretightening force adjusting time is saved, and the efficiency of pretightening force adjustment is improved. By means of the integral inner ring, the mounting process of the whole face-to-face type assembled double-row angular contact ball bearing is simple and efficient, complex adjusting steps are omitted, and the mounting difficulty of the bearing is lowered.

Description

technical field [0001] The invention relates to a face-to-face assembly double-row angular contact ball bearing and an assembly 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 bearin...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a face-to-face assembled double-row 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 also provides an assembly method for assembling the above-mentioned face-to-face assembly double row angular contact ball bearings
