Abstract

The invention provides a V-shaped straight raceway deep groove ball bearing, which consists of an outer ring (1), an inner ring (2), a rolling body (3) and a cage (4), wherein the rolling body (3) isinstalled in the pocket of the cage (4) and is arranged between the raceways (5) of the outer ring (1) and the inner ring (2). The V-shaped straight raceway deep groove ball bearing is characterized in that the raceways (5) of the outer ring (1) and the inner ring (2) are V-shaped straight raceways (5). The V-shaped straight raceway deep groove ball bearing has the advantages of small friction force, flexibility in starting and rotation, high positioning accuracy and the like, raceway processing accuracy can be easily guaranteed, and raceway accuracy can be easily adjusted.

Description

technical field [0001] The invention relates to a bearing, in particular to a V-shaped straight raceway deep groove ball bearing. Background technique [0002] In the existing deep groove ball bearings, the raceways on the inner ring and the outer ring are small semicircular arcs, so that the rolling elements are in line contact with the raceways, so that the contact surface between the inner and outer rings and the rolling elements is larger, so that the friction force is greater , and the processing accuracy is not easy to meet the requirements. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the invention provides a V-shaped straight raceway deep groove ball bearing. [0004] The technical solution of the present invention is: a V-shaped straight raceway deep groove ball bearing, which is composed of an outer ring, an inner ring, rolling elements and a cage, and the rolling elements are installed in the cage pocket and placed ...
