Abstract
The utility model provides an angular contact ball bearing of relating to the ball bearing field, the fore shaft of bearing establish to a step face, the inboard terrace of this step face establishes as to correspond with the outer lane outside and is 3-5 slope that the outside terrace of step face is established to the plane parallel with the holder, the bearing can effectual improvement machining efficiency to reach energy saving and consumption reduction's mesh.
Description
[technical field]
The utility model relates to ball bearing field, especially relates to a kind of roll two ends of being applied to, as the angular contact ball bearing that positioning bearing uses.
[background technique]
Known, the angular contact ball bearing of existing standard structure for ease of assembling, normally fore shaft is set to one corresponding with outside outer ring be the slope of 3 °, see accompanying drawing 1; But, when reality manufactures, for some larger-size angular contact ball bearings, because such fore shaft inclined-plane is comparatively roomy, very easily there is the phenomenons such as distortion or grinding burn when grinding, therefore it is not easy to carry out effective quality control in grinding, thus causes the grinding efficiency of angular contact ball bearing on the low side, and then adds cost of production accordingly because its yield rate is lower.
[summary of the invention]
In order to overcome the deficiency in background technique, the utility model discloses a kind of angular contact ball bearing, described bearing effectively can improve work efficiency, and reaches energy-saving and cost-reducing object.
For achieving the above object, the utility model adopts following technological scheme:
A kind of angular contact ball bearing, the fore shaft of described bearing is set to a step surface, and it is the slope of 3 ~ 5 ° that the inner side terrace of this step surface is set to corresponding with outside outer ring, and the outside terrace of step surface is set to the plane parallel with retainer.
Further, inside described slope be provided with the transition plane parallel with retainer between raceway.
Owing to adopting technological scheme as above, the utility model has following beneficial effect:
Angular contact ball bearing described in the utility model adopts the structure changing fore shaft, reaches and adds at mill the working area that man-hour effectively reduces grinder, thus reaches the object improving work efficiency; Described bearing effectively solves the grinding efficiency of angular contact ball bearing problem on the low side, and reaches by improving work efficiency the yield rate improving angular contact ball bearing accordingly, and energy-saving and cost-reducing object.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram of existing angular contact ball bearing;
Fig. 2 is schematic diagram of the present utility model;
Fig. 3 is another structural representation of the present utility model.
In figure: 1, outer ring; 2, retainer; 3, rolling element; 4, fore shaft; 5, slope; 6, plane; 7, transition plane.
[embodiment]
Can explain the present invention in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:
Angular contact ball bearing by reference to the accompanying drawings described in 2 ~ 3, fore shaft 4 in described bearing is set to a step surface, the inner side terrace of this step surface, namely the corresponding side near rolling element 3 of this step surface is set to corresponding with outside outer ring 1 is the slope 5 of 3 ~ 5 °, and the outside terrace of this step surface, namely the side of the corresponding bearing outer end of this step surface is set to the plane 6 parallel with retainer 2, due to the utility model improve after locking notch structure in plane 6 part can directly complete when Vehicle Processing, and product is after quenching, only need regrind and cut out slope 5 and just made fore shaft 4, therefore, adopt the angular contact ball bearing of structure of the present utility model effectively can reduce working area during fabrication, thus improve work efficiency accordingly, in addition, prove through many experiments, described structure can not affect the normal use of bearing, for improving grinding condition further, enhance productivity, can the inner side of slope 5 with set out one section of transition plane 7 parallel with retainer 2 between raceway, owing to controlling the quality of bearing when this section can not occur that the transition plane 7 of distortion or burning problems can be beneficial in grinding when grinding, therefore, the end product quality of described angular contact ball bearing can obtain more efficiently guarantee.
The non-detailed portion of the utility model is prior art, therefore the utility model is not described in detail.
