Description
Technical field
The utility model relates to a kind of roller bearing.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Alternatively, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.
Due to a gap can be left between inner ring and outer ring, therefore, if this bearing is used in the poor place of working environment, the place that such as amount of dust is large, dust can enter into inside by this gap, adheres on ball, if now do not clear up ball, then can affect the working life of this bearing, and when using, frictional force increases, cleaning dust is also more loaded down with trivial details.
Summary of the invention
Technical problem to be solved in the utility model is to provide one and can regularly utilizes hairbrush to carry out cleaning ball, is applicable to the roller bearing in the poor working environment of service condition.
The utility model is achieved through the following technical solutions: a kind of roller bearing, comprise inner ring and outer ring, between described inner ring and outer ring, opposing side is provided with ball grooves, more than one ball is provided with in described roller bearing groove, a gap is formed between inner ring and outer ring, the inner side surface upper and lower end of described inner ring all arranges a step surface, and the internal diameter of step surface is greater than the internal diameter of the first installation axle hole of inner ring;
Be positioned at upper and lower end step surface and install an axle sleeve, the upper end of described axle sleeve arranges a circle baffle ring, and the outboard end of described baffle ring arranges a circle ash blocking plate, and described ash blocking plate is just to the gap between inner ring and outer ring, and the lower end surface of described ash blocking plate is provided with hairbrush.
As preferred technological scheme, the upper-end surface of described ash blocking plate is provided with more than one oil hole, and described oil hole is positioned at the both sides of lower end hairbrush, and described oil hole runs through ash blocking plate to ash blocking plate lower end surface.
As preferred technological scheme, the step surface inwall arranged inside the outer wall of described axle sleeve and inner ring offsets.
As preferred technological scheme, the centre of described axle sleeve is provided with internal diameter second installation axle hole identical with inner ring first installation axle hole internal diameter.
As preferred technological scheme, described baffle ring is positioned at the upper-end surface of inner ring, T-shaped shape between described axle sleeve and baffle ring.
As preferred technological scheme, described axle sleeve and baffle ring all adopt steel structure material to make, and the outer wall of axle sleeve is provided with tread plate.
The beneficial effects of the utility model are: the utility model structure is simple, the upper and lower opening end of inner ring all arranges an axle sleeve, utilize the ash blocking plate of axle sleeve outer, carry out a gear ash to the ball in ball grooves to use, and can regularly utilize hairbrush to carry out cleaning ball, the utility model is applicable in the poor working environment of service condition.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art 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, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Embodiment
All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this specification (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
As shown in Figure 1, a kind of roller bearing of the present utility model, comprise inner ring 3 and outer ring 6, between described inner ring 3 and outer ring 6, opposing side is provided with ball grooves, more than one ball 7 is provided with in described roller bearing groove, form a gap between inner ring 3 and outer ring 6, the inner side surface upper and lower end of described inner ring all arranges a step surface 1, and the internal diameter of step surface 1 is greater than the internal diameter of the first installation axle hole 9 of inner ring 3;
Be positioned at upper and lower end step surface and install an axle sleeve 4, the upper end of described axle sleeve 4 arranges a circle baffle ring, and the outboard end of described baffle ring arranges a circle ash blocking plate 5, and described ash blocking plate 5 is just to the gap between inner ring 3 and outer ring 6, and the lower end surface of described ash blocking plate is provided with hairbrush 8.
Wherein, the upper-end surface of ash blocking plate 5 is provided with more than one oil hole, described oil hole is positioned at the both sides of lower end hairbrush 8, described oil hole runs through ash blocking plate 5 to ash blocking plate 5 lower end surface, when after this bearing Long-Time Service, axle sleeve can be pressed down, make originally not with hairbrush and the ball contact of ball contact, now in oil hole, note lubricant oil, then rotate inner chamber, drive the relative outer ring rotating of axle sleeve, now hairbrush just can rotate on ball, by the dust removing on ball, also more convenient when refueling on the other hand, smearing of lubricant oil is more even.
Wherein, step surface 1 inwall arranged inside the outer wall of axle sleeve 4 and inner ring 3 offsets; The centre of axle sleeve is provided with internal diameter second installation axle hole identical with inner ring first installation axle hole internal diameter; Baffle ring is positioned at the upper-end surface of inner ring, T-shaped shape between described axle sleeve and baffle ring.
Wherein, axle sleeve 4 and baffle ring all adopt steel structure material to make, and the outer wall of axle sleeve 4 is provided with tread plate, increase the fastening force between axle sleeve outer wall and inner ring.
Owing to having set up ash blocking plate, therefore dust has been not easy to enter into ball inside, thus there will not be situation ball affecting normal use because speckling with too many dust.
The beneficial effects of the utility model are: the utility model structure is simple, the upper and lower opening end of inner ring all arranges an axle sleeve, utilize the ash blocking plate of axle sleeve outer, carry out a gear ash to the ball in ball grooves to use, and can regularly utilize hairbrush to carry out cleaning ball, the utility model is applicable in the poor working environment of service condition.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
