Abstract

The utility model relates to a non-separating tapered roller bearing, which comprises an inner ring, an outer ring, a tapered roller and a cage of the tapered roller. The external surface of the inner ring is a conical surface; the conical surface extends to the big end of the inner ring; the outer ring is fixedly connected to a retainer ring which can limit the axial displacement of the roller on a small end face. The utility model has the advantages that the sliding friction of the parts of the bearing is reduced; the limit speed of the bearing can be increased; the utility model is provided with a non-separating structure transported from factories; operating windage is definited; the influence of the service life and the speed of the bearing caused by the improper adjustment and installation for operating windage by users can be avoided.

Description

Non-separating tapered roller bearing

The utility model relates to a kind of inseparable tapered roller bearing.

Tapered roller bearing of the prior art, its structure as shown in Figure 1, it is made up of outer ring 1, tapered roller 2 and retainer 3 thereof, inner ring 5, be a cone-shaped space, roller 2 between inner ring 5 and the outer ring 1 and just be placed in play work in it, the small end of inner ring 5 and big end end be respectively equipped with little rib 4, large-flange 6, in order to limit roller 2 upper and lower displacement vertically.All be separable state when this class bearing dispatches from the factory, promptly outer ring 1 is mounted and removable with other parts.In actual applications, the tapered roller bearing of this quasi-tradition has following shortcoming: 1 owing to be divergence type, and the user need now assemble in use, and for the working gap of harmonizing, the adjustment work of this assembling will be very time-consuming, reduces user's manufacturing efficiency.Large-flange on 2 inner rings and roller end face area of contact are bigger, and therefore when roller is worked, the sliding friction between them will obviously influence the rotating speed of bearing.3 owing to be divergence type, and working gap is indefinite, will influence bearing life or rotating speed in the future if grasp is improper like this when assembling.

The purpose of this utility model is: overcome the deficiency of prior art, a kind of sliding friction, fixing inseparable tapered roller bearing of roller working gap of reducing is provided.

The utility model can be realized like this: compared with prior art, it also comprises inner ring, outer ring, garden awl roller and retainer thereof, different is: be provided with at the small end place that the surface is a conical surface outside the inner ring of little rib, this conical surface extends to the big end of inner ring always, the outer ring on its small end face affixed one can limit roller vertically to the back-up ring of top offset.

When realizing the utility model, can with between the small end end face of back-up ring and outer ring with the bonding way Joint.

The utility model has the advantages that:

1, inner ring does not have large-flange, can reduce sliding friction between the parts of bearing self, has improved the limit speed of bearing; Make the inner ring designs simplification, simplified its production technology greatly.

Assembled when 2, dispatching from the factory and finish, be inseparable formula structure, so the roller working gap when dispatching from the factory is fixing, it is improper and cause the drawback that influences bearing life, rotating speed that this just can be avoided the user to grasp play when assembling bearing voluntarily.

3, when the utility model is applied to auto manufacturing, owing to be inseparable release, it just can make axletree and bearing support design simplyr, compact structure, and owing to need not to adjust working gap, use the utility model so have the automobile factory of automatic control line assembling, can raise labour productivity greatly.

Fig. 1 is a tapered roller bearing structural representation in the prior art.

Fig. 2 is the utility model example structure schematic representation.

Below in conjunction with drawings and Examples, the utility model is done further narration:

More as can be known, the utility model is that large-flange 6 of the prior art is removed, and has increased a back-up ring 16 than prior art by Fig. 1,2, other structure do not have change.During assembling, inner ring 15, outer ring 11, retainer 13 and roller 12 are assembled, and the working gap of having harmonized, with industrial glue back-up ring 16 is bonded on the small end end face of outer ring 11 more at last.In the utility model, little rib 14 and back-up ring 16 are finished the qualification to roller 12 upper and lower displacement vertically respectively.

Claims

1, inseparable tapered roller bearing, comprise inner ring, outer ring, tapered roller and retainer thereof, it is characterized in that: be provided with at the small end place that the surface is a conical surface outside the inner ring on little shelves limit, this conical surface extends to the big end of inner ring always, the outer ring on its small end face affixed one can limit roller vertically to the back-up ring of top offset.

2, inseparable tapered roller bearing according to claim 1 is characterized in that: between the small end end face of back-up ring and outer ring is bonding.
