Abstract

The utility model discloses a solid bearing cage of a center-adjustable bearing, which comprises a beam (1), a bottom beam (2), a pocket hole (3) and a pocket hole bottom surface (4), and is characterized in that the end surface of the bottom beam (2) and three surfaces of the pocket hole (3) are evenly equipped with micro pits which are densely covered. The micro pits are made on the end surface of the bottom beam and the three surfaces of the pocket hole which are the end surface of the bottom beam, the bottom surface of the pocket hole and two surfaces which are combined by the beam and a roller, the solid bearing cage can store grease lubricant, greatly increases the lubrication effect, guarantees the bearing to steadily operate, is suitable for high speed operation, reduces noise, reduces the abrasion and the overheating of the bearing, and greatly prolongs the service life of the bearing.

Description

Solid bearing retainer of self-aligning bearing

Technical field:

The utility model relates to a kind of retainer, especially a kind of solid bearing cage with special surface structure.

Background technique:

At present, in traditional cutting technology of Cuprum alloy solid bearing cage, the pocket hole is to adopt the drilling method to be shaped, because horizontal processing knife mark is arranged on profiled surface, roughness ratio is bigger, cause pocket hole frictional force increase, wear resistance decrease at work, have a strong impact on the usability of bearing.For this reason, what existing Cuprum alloy solid bearing cage was taked is extrusion forming technology, and the size in pocket hole and surface quality are improved, thereby its usability is improved, but not too obvious to the raising of the lubrication effect between retainer and roller.

Summary of the invention:

The utility model provides a kind of lubrication effect good at the above-mentioned deficiency of prior art, pocket cellular type solid bearing retainer of self-aligning bearing.

Technical solution of the present utility model is: a kind of solid bearing retainer of self-aligning bearing, constitute by beam, bottom girder, pocket hole, bottom surface, pocket hole, and on three faces in the end face of bottom girder and pocket hole, all have densely covered nick hole.

The utility model is on three faces in the end face of bottom girder, pocket hole, also be to produce the nick hole on two faces combining with roller of end face, bottom surface, pocket hole, the beam of bottom girder, can store lubricating grease, improved lubrication effect greatly, the assurance bearing operation is steady, is applicable to run up, and reduces noise, reduce bearing wear and overheated, prolonged the working life of bearing greatly.

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.

Embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

As shown in Figure 1, 2, a kind of solid bearing retainer of self-aligning bearing is made of beam 1, bottom girder 2, pocket hole 3, bottom surface, pocket hole 4, all has densely covered nick hole on three faces in the end face of bottom girder 2 and pocket hole 3.These nick holes can form by the press machine compacting.

Claims (1)

1. solid bearing retainer of self-aligning bearing is made of beam (1), bottom girder (2), pocket hole (3), bottom surface, pocket hole (4), it is characterized in that: all have densely covered nick hole on three faces of the end face of bottom girder (2) and pocket hole (3).
