Abstract
The utility model proposes a kind of anti skid bearing, comprise bearing outer ring, bearing inner race, rolling element and retainer, described rolling element has several and is arranged between described bearing outer ring and bearing inner race; On described bearing outer ring, be provided with anti-slip tank, in described anti-slip tank, be provided with snap ring, between the diapire of described anti-slip tank and described snap ring, be provided with antislip ring; The surface of described snap ring is provided with anti-skidding striped one, and described antislip ring and the described snap ring face being connected of conflicting is provided with anti-skidding striped two.This bearing structure is simple, good antiskid effect; Bearing is difficult for wriggling, and affects the stability of bearing operation.
Description
Technical field
The utility model relates to field of mechanical technique, refers to especially a kind of bearing with anti-slip function.
Background technique
In prior art, annular bearing with rolling contact is generally made up of inner ring, outer ring, rolling element and retainer four parts, and in most cases, its inner ring and axle match to merge and rotate together with the axis; Matching with bearing support in outer ring, plays a supportive role; Rolling element is evenly distributed between inner ring and outer ring by means of retainer, and retainer can make rolling element be uniformly distributed, and prevents that rolling element from coming off, guiding rolling element rotation lubricate.
But be installed on the positions such as main frame during when bearing, the heat in heat and bearing support that bearing rotary produces can cause the heatings such as bearing outer ring, bearing inner race and the steel ball in bearing to be expanded, bearing support itself also can be because heating is expanded simultaneously.But because the material of bearing and bearing support is different, relative expansion coefficient is also different, after temperature raises, bearing outer ring and bearing support all can radially expand.And due to the different reason of material, the size that bearing support radially expands is greater than the size that bearing outer ring expands conventionally, so just cause between bearing support and bearing outer ring, thering is larger gap, thereby bearing is easily wriggled in the running, and then affect the stability of bearing operation.
In order to solve this technical barrier, prior art has proposed on bearing outer ring, to be provided with locking groove, and snap ring is installed in locking groove.But the locking groove in above-mentioned bearing is after processing, its bottom land and sidewall are all very smooth, when bearing is under high temperature condition, snap ring easily with smooth locking groove bottom land generation relative sliding, thereby make the anticreep disabler of bearing.
Model utility content
The utility model proposes a kind of anti skid bearing, solved in prior art under high temperature condition, snap ring easily with the problem of smooth locking groove bottom land generation relative sliding.
The technical solution of the utility model is achieved in that a kind of anti skid bearing, comprises bearing outer ring, bearing inner race, rolling element and retainer, and described rolling element has several and is arranged between described bearing outer ring and bearing inner race; On described bearing outer ring, be provided with anti-slip tank, in described anti-slip tank, be provided with snap ring, between the diapire of described anti-slip tank and described snap ring, be provided with antislip ring; The surface of described snap ring is provided with anti-skidding striped one, and described antislip ring and the described snap ring face being connected of conflicting is provided with anti-skidding striped two.
Further preferably, the setting of described anti-skidding striped one is towards towards the opposite with arranging of described anti-skidding striped two.
Further preferably, described anti-skidding striped one has some and be on the skewed surface that is evenly arranged on snap ring.
Further preferably, described anti-skidding striped two has some and be on the skewed surface that is evenly arranged on antislip ring.
Further preferably, the two ends of described bearing outer ring are respectively equipped with dust cover.
Be compared with the prior art, the beneficial effect that the utility model possesses is as follows:
Anti-slip tank bottom land in this bearing is provided with antislip ring and snap ring, on the surface of antislip ring and snap ring, there is several anti-skidding stripeds, and anti-skidding striped separately is towards the opposite, increase the frictional force between antislip ring and snap ring, avoid sliding in snap ring anti-slip tank, improve the anti-slip function of bearing.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model antislip ring;
Fig. 3 is the structural representation of the utility model snap ring.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
As Figure 1-3, a kind of anti skid bearing, comprises bearing outer ring 1, bearing inner race 2, rolling element 3 and retainer 4.Rolling element 3 is balls, ball have several and be all arranged on bearing outer ring 1 and bearing inner race 2 between.On bearing outer ring 1, offer an anti-slip tank 6, anti-slip tank 6 coaxially arranges ringwise and with bearing outer ring 1.Snap ring 8 is stuck in anti-slip tank 6, between the diapire of anti-slip tank 6 and snap ring 8, is provided with antislip ring 7.The lower surface of snap ring 8 is provided with anti-skidding striped 1; Antislip ring 7 and snap ring 8 face being connected of conflicting is provided with anti-skidding striped 2 71.
Wherein, the setting of anti-skidding striped 1 towards with the setting of anti-skidding striped 2 71 towards being contrary.As Figure 2-3, anti-skidding striped 1 has some and be on the skewed surface that is evenly arranged on snap ring 8; Anti-skidding striped 2 71 has some and be on the skewed surface that is evenly arranged on antislip ring 7.Such structural design, is conducive to strengthen frictional force between the two, prevents bearing wriggling, improves bearing anti-slip function.Anti-skidding striped 1 can also be the setting of serpentine shape with anti-skidding striped 2 71, makes antislip ring 7 and the mutual snapping of snap ring 8, further improves bearing anti-slip function.
In addition, the two ends of bearing outer ring 1 are respectively equipped with dust cover 5.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
