Abstract

The utility model discloses a rolling bearing cage assembly. The rolling bearing cage assembly comprises a cage seat (1) and a cage cover (2), wherein a plurality of convex ribs (3) are evenly distributed on one side of the cage seat (1) in the radial direction; window holes (5) used for accommodating rolling bodies of the bearing are formed among adjacent convex ribs (3); the convex ribs (3) extend outwards to form convex rib tenons (31); a plurality of riveting window holes (21) corresponding to the convex rib tenons (31) are evenly formed on the cage cover (2) in the radial direction; and after a plurality of rolling bodies (4) are mounted in the cage seat (1), the convex rib tenons (31) of the cage seat (1) pass through the riveting window holes (21) of the cage cover (2) and are riveted with the cage cover (2). The rolling bearing cage assembly is characterized in that a plurality of axial through grooves I (32) are evenly formed on the peripheral surface of the cage seat (1); a plurality of axial through grooves II (22) are evenly formed on the peripheral surface of the cage cover (2); the positions of the grooves II (22) correspond to the positions of the grooves I (32); and the grooves II (22) are communicated with the grooves I (32). The grooves I and the grooves II of the rolling bearing cage assembly can be used for storing certain lubricating oil or lubricating grease, so that the inner part of a bearing can be lubricated rapidly, fully and evenly, the friction, the abrasion and the heating of internal parts of the bearing produced during the initial operation stage of the bearing are reduced, the normal operation of the bearing is guaranteed, and the service life of the bearing is prolonged.

Description

The rolling bearing retainer assembly

Technical field

The utility model relates to a kind of rolling bearing retainer structure, and especially a kind of oil-bearing structure of rolling bearing retainer belongs to technical field of bearings.

Background technique

The sliding friction meeting of rolling bearing when work causes friction, wearing and tearing and the heating of bearing inner body, especially under the high temperature operation condition, the effect of inertial centrifugal force can aggravate friction, wearing and tearing and the heating between part, can cause retainer burn or fracture when serious, cause the bearing cisco unity malfunction.Therefore, except that requiring retainer to have certain intensity and the impact toughness, lubricating of bearing inside is also very important.Existing the lubricated of rolling bearing inside is to realize by fill in a certain amount of lubricant oil or lubricating grease in bearing race, because rolling bearing is when state of rest, the lubricant oil of its raceway inside or lubricating grease under the self gravitation effect easily to a certain regional centralized of raceway, cause lubricant oil or lubricating grease skewness in bearing race, like this when rolling bearing is started working, bearing inside can not obtain sufficient lubrication, friction, wearing and tearing and the heating of part in the bearing have been aggravated, the final bearing proper functioning that influences, the working life of shortening bearing.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, can make bearing inside obtain the rolling bearing retainer of sufficient lubrication.

The utility model is achieved by the following technical programs:

A kind of rolling bearing retainer assembly, comprise and keep stand, retainer lid, the a plurality of convex tendons of described maintenance stand one side radial equipartition, form the fenestra that holds bearing roller between the adjacent convex tendon, described convex tendon extends outward the convex tendon tenon, a plurality of riveted joint fenestras corresponding with the convex tendon tenon of described retainer lid radial equipartition; A plurality of rolling elements pack into keep stand after, the convex tendon tenon of described maintenance stand passes the riveted joint fenestra of retainer lid, with retainer lid riveted; The groove I of uniform a plurality of axial perforations on the described retainer outer circumferential face, the groove II of uniform a plurality of axial perforations on the described retainer lid outer circumferential face, described groove II is corresponding with groove I position to connect mutually.

The purpose of this utility model can also further realize by following technical measures.

Aforesaid rolling bearing retainer assembly, wherein said groove I is arranged on the outer circumferential face of convex tendon, and groove I, groove II are circular arc.

The utility model is provided with a plurality of positions corresponding and groove I, groove II that axially connect respectively on convex tendon outer circumferential face that keeps stand and retainer lid outer circumferential face, when rolling bearing is static, can store certain lubricant oil or lubricating grease in groove I and the groove II.During rolling bearing work, under the rotary centrifugal force effect, lubricant oil in retainer groove I and the groove II or lubricating grease moment throw away, make bearing inside obtain rapidly, fully, lubricated uniformly, friction, wearing and tearing and the heating of its inner body of bearing working initial stage have been reduced, guarantee the bearing proper functioning, prolong the working life of bearing.

Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiments only provide as an example with reference to accompanying drawing.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is that the utility model is installed in the structural representation on the rolling bearing.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As Fig. 1～shown in Figure 3, the utility model comprises maintenance stand 1, retainer lid 2, keep a plurality of convex tendons 3 of stand 1 one side radial equipartitions, totally 10 of the convex tendons 3 of present embodiment, form 10 fenestras 5 that hold bearing roller 4 between the adjacent convex tendon 3, convex tendon 3 extends outward convex tendon tenon 31, and retainer covers the corresponding riveted joint fenestra 21 of 10 of 2 radial equipartitions and convex tendon tenon 31.10 rolling elements 4 pack into keep stand 1 after, the convex tendon tenon 31 of described maintenance stand 1 passes the riveted joint fenestra 21 of retainer lid 2, covers 2 riveteds with retainer.Uniform 10 groove I 32 that axially connect on convex tendon 3 outer circumferential faces of maintenance stand 1, retainer covers uniform 10 groove II22 on 2 outer circumferential faces, and groove II22 and groove I 32 position corresponding shaft are to perforation, and groove I 32, groove II22 are circular arc.When rolling bearing is static, can store certain lubricant oil or lubricating grease in groove I 32 and the groove II22, during rolling bearing work, under the effect of retainer rotary centrifugal force, lubricant oil or lubricating grease in groove I32 and the groove II22 threw away in moment, and bearing inside is obtained rapidly, fully, evenly lubricate.Retainer covers the groove I 32 and the groove II 22 that connect on 2 outer circumferential faces and forms the oil storage tank that is interconnected, and can reach better oil storage effect, and it is more smooth and easy, lubricated more abundant that lubricant oil or lubricating grease are trickled in bearing inside; Groove II 22 and groove I 32 are circular arc, can not cause stress to concentrate, and the intensity of retainer is unaffected, has prolonged the working life of retainer.

In addition to the implementation, the utility model can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
