Abstract
The invention relates to a novel four-point contact ball bearing retainer comprising a retainer body (1), wherein a plurality of pocket holes (2) are formed in the retainer body (1) along the periphery. The novel four-point contact ball bearing retainer is characterized in that at least one protrusion is respectively arranged at the bottom of each pocket hole (2), and the surface of each protrusion is an inclined plane or an arc-shaped surface. Proved by testing, by adopting the retainer disclosed by the invention, unified locking quantities can be processed according to the sizes of the product pocket holes, the novel four-point contact ball bearing retainer is uniform in locking quantity and convenient to assemble, the inner surface or the outer surface of the retainer does not have chiseling openings, the appearance quality can be improved, the sleeve combination can be completed by one operator, the production efficiency can be improved, the retainer is stable in product quality, each pocket hole in the complete set of bearing has the consistent locking degree to a steel ball, and a steel ball falling phenomenon cannot be caused.
Description
Technical field
The present invention relates to a kind of novel four-point contact ball retainer.
Background technique
The retainer of existing four-point contact ball, wherein a type is the complete bearing that inner sleeve is made up of two halves inside race and outer assembly.The complete bearing that another kind of type is made up of two semi outer rings and inner assembly, its retainer structure as shown in Figure 1, 2.This kind of structure retainer needs symmetrical cutter mouth on retainer inside diameter surface or external diameter surface when assembling, thus digs out boss and pin the outer assembly of steel ball composition bearing with this.
When retainer wants two operators to cooperate when cutting a hole mouth, cutter mouth is completely by manual operation, and cutter mouth size is not easily controlled, and the cutter mouth depth is also difficult to control.Sometimes control with great difficulty the boss dug out not to be chiseled out, cause retainer to scrap, to such an extent as to the part that former cutter is good all will be pulled down, cause unnecessary doing over again, and adopt such Standard time-consuming, require great effort, take a lot of work.Easily cause scrapping of retainer, manufacturing efficiency is low.
Summary of the invention
The object of this invention is to provide a kind of novel four-point contact ball retainer, steel ball can be locked at retainer internal surface or outer surface without when cutter mouth, and can be consistent to ball lock degree.
A kind of novel four-point contact ball retainer, comprise retainer body, along having some pocket holes its week on this retainer body, its specialization is: be equipped with at least one place in the bottom in described each pocket hole protruding, the surface of this projection is inclined-plane or arc shaped surface.
Wherein be equipped with two relative places in the bottom in described each pocket hole protruding, and the surface often locating projection is inclined-plane.
Wherein be equipped with the projection of place's ring-type in the bottom in described each pocket hole, the surface of this projection is inclined-plane or arc shaped surface.
Wherein the angle on inclined-plane is 14 ° ~ 16 °.
Through probationary certificate, after adopting retainer of the present invention, can process unified hold depth according to product pocket hole size, hold depth is even, be convenient to assembling, retainer internal surface or outer surface are without cutter mouth, and appearance quality is improved, and just can complete trap by an operator, enhance productivity, constant product quality, in complete bearing, each pocket hole is consistent to the locking degree of steel ball, occurs without falling steel ball phenomenon.

Accompanying drawing 2 is the retainer structural representation in background technique of the present invention;
Accompanying drawing 3 is the structural representation of retainer in the present invention;
Accompanying drawing 4 is the structural representation of retainer in the present invention;
Accompanying drawing 5 is the A-A sectional view of Fig. 4.
Embodiment
As shown in Fig. 3,4,5, the present invention is a kind of novel four-point contact ball retainer, comprises retainer body 1, along having some pocket holes 2 its week on this retainer body 1, be equipped with at least one place in the bottom in described each pocket hole 2 protruding, the surface of this projection is inclined-plane or arc shaped surface.
Wherein be equipped with two relative places in the bottom in described each pocket hole 2 protruding, and the surface often locating projection is inclined-plane.Or be wherein equipped with the projection of place's ring-type in the bottom in described each pocket hole 2, the surface of this projection is inclined-plane or arc shaped surface.
As shown in Fig. 3,4,5, retainer structure of the present invention eliminates cutter mouth, the pocket hole 2 of retainer is got the boring cutter of α angle, its lock station h determines according to steel ball size d, and hold depth d1 determines according to pocket hole 2, and concrete data are as shown in table 1 below, for guaranteeing that pocket hole 2 process meets designing requirement, can hole boring cutter oral area is made into α angle by technological requirement, when processing pocket hole 2, the feeding depth controlling boring machine just can control the hold depth in pocket hole 2.
The product hold depth according to said method processed, unified hold depth is processed according to product pocket hole 2 size, hold depth is even, is convenient to assembling, and retainer internal surface or outer surface are without cutter mouth, appearance quality is improved, just can complete trap by an operator, enhance productivity, constant product quality, in complete bearing, the locking degree of the 2 pairs of steel balls in each pocket hole is consistent, occurs without falling steel ball phenomenon.
Table 1:
Through repeatedly proving, during batch assembling, steel ball size and pocket hole 2 hold depth are as shown in table 1, when the convex surfaces bottom pocket hole 2 is inclined-plane its inclined-plane angle [alpha] value 14 ° ~ 16 ° between, now lock degree the best.
Claims (4)
1. a novel four-point contact ball retainer, comprise retainer body (1), along having some pocket holes (2) its week on this retainer body (1), it is characterized in that: be equipped with at least one place in the bottom of described each pocket hole (2) protruding, the surface of this projection is inclined-plane or arc shaped surface.
2. novel four-point contact ball retainer as claimed in claim 1, is characterized in that: be wherein equipped with two relative places in the bottom of described each pocket hole (2) protruding, and the surface often locating projection is inclined-plane.
3. novel four-point contact ball retainer as claimed in claim 1, is characterized in that: the projection being wherein equipped with place's ring-type in the bottom of described each pocket hole (2), the surface of this projection is inclined-plane or arc shaped surface.
4. as the novel four-point contact ball retainer in claims 1 to 3 as described in any one, it is characterized in that: wherein the angle on inclined-plane is 14 ° ~ 16 °.
