Abstract

The invention discloses a cylindrical roller bearing and a retainer treatment process thereof, relates to the field of bearings, and aims to solve the problems that a large amount of materials are wasted and the lubrication degree of a bearing is poor due to the fact that an existing retainer is large in thickness. The technical scheme key point is that the cylindrical roller bearing comprises aninner ring, an outer ring with an annular slideway formed in an inner wall; a plurality of cylindrical rollers; and a retainer which comprises a cylindrical retainer body, a plurality of retaining holes which are evenly distributed and used for installing cylindrical rollers are formed in a circumferential direction of the retainer body, wherein two sides of each retaining hole are fixedly connected with limiting pieces, and the distance between the two limiting pieces is gradually decreased in an axis direction of the retainer body; opposite faces of the limiting pieces located on the two sides of the same retaining hole are provided with arc-shaped retaining faces used for abutting against the cylindrical rollers, and guide faces used for facilitating clamping-in of the cylindrical rollers are formed on the sides, close to the axis of the retainer body, of the limiting pieces. The cylindrical roller bearing can save material and is convenient for lubricating.

Description

technical field [0001] The invention relates to the field of bearings, more specifically, it relates to a cylindrical roller bearing and a cage processing technology thereof. Background technique [0002] Roller bearings are a type of rolling bearings and are one of the most widely used components in modern machinery. It relies on the rolling contact between the main components to support the rotating parts, and has the advantages of small torque required for starting, high rotation accuracy, and convenient selection. [0003] The Chinese patent with publication number CN108457987B discloses a cylindrical roller bearing and its cage, the technical points of which are: an annular body extending from the left and right of the axis and a pocket hole arranged on the annular body, characterized in that: The rear side wall of the pocket is inclined from the inside to the outside in the positive direction of the rotation direction of the ring body in the radial direction; the tang...
