Abstract
The utility model relates to a field of bearing cage technology, providing a pocket surface structure of the bearing cage with an end cover (1), a lintel (2), a pocket (3) and a base (4). The lower end of the end cover (1), the upper end of the base (4), the two ends where the lintel (2) are connected with the roller, namely micro pits (5) are densely covered on the four ends forming the pocket (3) The utility model has the advantages of reasonable conception and simple structure. Due to the treatment of the pocket surface of the cage, the utility model has dense micro pits structure, which can store the lubricating oil and forms the lubricant film, enhance the lubricating effect, reduce the friction and wear, thus increasing the working performance and prolonging the service life of the cage and the whole bearing.
Description
Affiliated technical field
The utility model belongs to the retainer technical field, and what relate generally to is a kind of solid bearing cage pocket hole 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, the anti-decreased performance of wasting 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 purpose of this utility model promptly produces thus, proposes a kind of solid bearing cage pocket hole surface structure, and its antifriction, anti-attrition performance are improved, thus the service behaviour and the working life of having improved retainer.
For achieving the above object, the technological scheme that the utility model is taked is: on two faces that the lintel of existing retainer combines with roller, the lower end surface of end cap, the upper-end surface of base, four faces that also promptly constitute the pocket hole all are provided with to have densely covered nick and cheats.
The utility model reasonable idea, simple in structure.Because it is handled by the pocket hole surface to retainer, make it have densely covered nick hole structure, the effect that in use play and store lubricant oil, forms lubricant film, can improve the lubricating function of rubbing surface, reduce friction and wear and tear, thereby the service behaviour of retainer and whole bearing and working life are improved.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model pocket hole surface partial enlarged drawing.
Accompanying drawing 3 is the structural representation of existing retainer.
Among the figure, 1, end cap, 2, lintel, 3, the pocket hole, 4, base, 5, the nick hole.
Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As Fig. 1 in conjunction with shown in Figure 2, present embodiment is on the architecture basics of the existing retainer (as shown in Figure 3) that is made of end cap 1, lintel 2, pocket hole 3, base 4, on two faces that lower end surface, the upper-end surface of base 4, the lintel 2 of end cap 1 combines with roller, also promptly constitute on four faces in pocket hole 3 and all have densely covered nick hole 5.
Claims (1)
1, a kind of solid bearing cage pocket hole surface structure, have end cap (1), lintel (2), pocket hole (3), base (4), it is characterized in that: on two faces that described end cap (1) lower end surface, base (4) upper-end surface, lintel (2) combine with roller, also promptly constitute and all have densely covered nick hole (5) on four faces in pocket hole (3).
