Heat dissipation type new energy automobile bearing and transmission device applying same

Abstract

The invention relates to the technical field of new energy automobile bearings, in particular to a heat dissipation type new energy automobile bearing and a transmission device applying the same. Comprising a bearing outer ring, a bearing inner ring and balls, an annular groove with an inward opening is formed in the inner side face of the bearing outer ring, and the section of the annular groove is in a V shape; the bearing inner ring is arranged on the inner side of the bearing outer ring, the bearing inner ring and the bearing outer ring are coaxially arranged, and the bearing inner ring is in clearance fit with the bearing outer ring; a shaft hole matched with an external rotating shaft is formed in the inner ring of the bearing; according to the bearing, the section of the annular groove is arranged to be V-shaped, and compared with a plane or arc-shaped groove of an existing bearing, the V-shaped annular groove can reduce the contact area of the balls and the bearing outer ring, so that resistance is reduced, abrasion is reduced, and the high-speed running requirement of a new energy automobile bearing is met; in addition, the arrangement of the annular groove can be beneficial to heat dissipation, and the problem of accumulation of accumulated heat in the bearing is solved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle bearings, in particular to a heat dissipation type new energy vehicle bearing and a transmission device using the bearing. Background technique [0002] In the process of high-speed operation of new energy vehicles, the transmission device will bear a large load, especially the bearings arranged inside the transmission device, and the bearings will suffer continuous wear during high-speed operation; in order to reduce the bearing In the process of designing and improving bearings, engineers usually need to consider many factors such as dust prevention, wear maintenance and so on. [0003] Chinese Patent 201721736592.9 discloses a self-cleaning bearing, comprising a first inner ring, a second inner ring, balls, a cage, a first outer ring and a second outer ring; the first inner ring, the second inner ring, the The first outer ring and the second outer ring are arranged coaxially; both s...
