Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as Figure 1-4 As shown, the cage assembly of the single row roller bearing includes a cylindrical cage body 1, and the cage body 1 has a plurality of strip-shaped holding holes 11 extending axially along the cage body 1 in the circumferential direction. The hole 11 is provided with a roller body 3 that can rotate in the circumferential direction. The width of the strip-shaped holding hole 11 is gradually reduced from the outside of the cage body 1 to the inside. The arc-shaped inclined surface 111 of the sub-body 3 is in contact with the outside, and the outer sides of the bar-shaped holding hole 11 are respectively provided with limit bars 12. Arbuting against the arc-shaped retaining surface 121, and the arc-shaped retaining surface 121 has several strip-shaped oil grooves 122 extending along the width direction of the...

Abstract

The invention relates to a cage component of a single-row roller bearing and a cage component installation method, and solves such technical problems as weak stability of traditional bearing cages. The cage component comprises a cage body, a strip-shaped keeping hole and a roller body, wherein the width of the strip-shaped keeping hole from the outer side of the cage body to the inner side is gradually decreased; the two sides of the strip-shaped keeping hole respectively have arc inclined surfaces; limiting strips are respectively arranged outside the two sides of the strip-shaped keeping hole, and are both arched; the inner sides of the limiting strips have arc keeping surfaces butted against the roller body; multiple strip-shaped oil tanks are formed in the arc keeping surfaces; at least one annular oil tank is formed in the periphery of the roller body, and is communicated with and perpendicular to the strip-shaped oil tanks; and the two limiting strips at the outer sides of each strip-shaped keeping hole are both detachably connected with the cage body. The cage component has the advantages of good stability, convenience for roller installation, high lubrication degree, difficult abrasion between the roller body and the cage and long service life.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a cage assembly of a single-row roller bearing and a method for installing the cage assembly. Background technique [0002] Roller bearings are rolling bearings that use short cylindrical, tapered or drum-shaped rollers as rolling elements. There are mainly structural types such as centripetal short cylindrical rollers, double row centripetal spherical rollers, tapered rollers and thrust rollers. A common roller bearing consists of an inner and outer ring of the bearing and a cage arranged between the two. The rollers are arranged on the cage to separate each roller, keep the distance between the rollers equal, and distribute the load evenly. However, the existing roller bearings have problems such as poor stability, poor bearing capacity, inconvenient installation, short service life, and poor lubrication of the rollers during use. [0003] In order to solve the...
