Abstract
A kind of low wear angle contact ball bearing metal cage relates to angular contact ball bearing cage field, the pocket hole (2) of this retainer (1) adopts two sections of linear structures, and form acute angle from the center line of the straight line of that close to bearing bore diameter and pocket hole (2), the global shape of pocket hole (2) is funnel shape.The beneficial effects of the utility model are: when bearing operation, and the conical surface bottom retainer pocket hole contacts with steel ball and then holds up retainer, thus prevents the contact wear of retainer internal diameter and lasso.Retainer internal diameter size strengthens, and retainer is guided from inner ring and becomes steel ball and guide, and improves lubrication, is therefore more applicable to the application run up, and solves the problems such as retainer bore wear, life-span be short well.
Description
Technical field
The utility model discloses a kind of low wear angle contact ball bearing metal cage, is mainly used in steel industry, is used on high-speed rod-rolling mill bearing, is also used on the bearing of the equipment such as helical-lobe compressor.
Background technique
As shown in Figure 1, the through-hole structure of the traditional many employings of angular contact ball bearing metal cage 1a straight pocket hole 2a, when bearing working, the external diameter of the inner circle of retainer internal diameter guides centering to rotate, therefore, after running up or working long hours, easily cause the wearing and tearing of retainer internal diameter, metallic dust is fallen in serious meeting, causes bearing early fatigue to damage.
Model utility content
In order to the technical problem such as cause bearing early fatigue, life-span short due to retainer wearing and tearing solving that prior art exists, the utility model provides a kind of low wear angle contact ball bearing metal cage.
The technological scheme that the utility model technical solution problem is taked is as follows:
A kind of low wear angle contact ball bearing metal cage, its pocket hole adopts two sections of linear structures, and forms acute angle from the center line in the straight line of that close to bearing bore diameter and pocket hole, and the global shape in pocket hole is funnel shape.
The beneficial effects of the utility model are: when bearing operation, and the conical surface bottom retainer pocket hole contacts with steel ball and then holds up retainer, thus prevents the contact wear of retainer internal diameter and lasso.Retainer internal diameter size strengthens, and retainer is guided from inner ring and becomes steel ball and guide, and improves lubrication, is therefore more applicable to the application run up, and solves the problems such as retainer bore wear, life-span be short well.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing angular contact ball bearing metal cage.
Fig. 2 is the structural representation of the utility model low wear angle contact ball bearing metal cage.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 2, the pocket hole 2 of low wear angle contact ball bearing metal cage 1 of the present utility model adopts two sections of linear structure forms to replace the structural type of existing straight line, and form acute angle from the center line in the straight line of that close to bearing bore diameter and pocket hole 2, like this, the global shape in pocket hole 2 barrel-shapedly becomes funnel shape from existing.When bearing operation, the conical surface bottom retainer pocket hole contacts with steel ball and holds up retainer, thus prevents the contact wear of retainer internal diameter and lasso.
Prove through practical application test, after bearing adopts retainer structure of the present utility model, retainer bore wear can not only be solved well, fall the problems such as foam, also substantially prolongs the working life of bearing.
Claims (1)
1. one kind low wear angle contact ball bearing metal cage, it is characterized in that, the pocket hole (2) of this retainer (1) adopts two sections of linear structures, and form acute angle from the center line of the straight line of that close to bearing bore diameter and pocket hole (2), the global shape of pocket hole (2) is funnel shape.
