Abstract
A rolling bearing comprises an outer ring, an inner ring and a retainer, wherein a rolling assembly is arranged between the outer ring and the inner ring, and is connected by the retainer, the rolling assembly comprises a rolling sleeve and a rolling hub for supporting the rolling sleeve, and the rolling sleeve is made of elastic material, and is provided with a cavity capable of being filled with gas. Since the rolling assembly can deform when bearing the load, fatigue damage is not easy to form between a rolling body and a rolling way due to friction so as to cause the bearing failure.
Description
Technical field
The utility model relates to a kind of rolling bearing structure, the rolling bearing that specifically a kind of rolling element can be out of shape when bearing high capacity or bump load.
Background technique
The supporting important mechanical basic part with maintenance as all kinds of electronic products of bearing is widely used in the every field of national economy.
With the sliding bearing is the rolling bearing that base growth is got up, and its working principle is to replace sliding friction with rolling friction, generally by two lassos, and one group of rolling element and the mechanical basic part that retainer is formed.Because various machineries have different operating conditions, and rolling bearing has all been proposed various different requirements at aspects such as load carrying capacity, structure and usabilities.For this reason, rolling bearing need have structure miscellaneous.But the most basic structure is made up of inner ring, outer ring, rolling element and retainer.
The effect of the various parts of rolling bearing in bearing is respectively: for radial bearing, inner ring usually with an axle drive fit, and turn round with axle, the outer ring becomes transition fit with bearing support or mechanical hull hole usually, play supporting role.But, under some occasion, outer ring running being arranged also, inner ring fixedly play supporting role or inner ring, outer ring all turn round simultaneously.For thrust-bearing, merge the title blowout patche of motion with the axle close-fitting, the title seat ring that becomes transition fit and play supporting role with bearing support or mechanical hull hole.Rolling element is arranged in equably between two lassos by retainer usually in bearing and makes rolling motion, and its shape, size and quantity directly influence the load carrying capacity and the usability of bearing.Beyond the retainer decapacitation is separated rolling element equably, can also play guiding rolling element rotation and improve effect such as bearing internal lubrication performance.
Be illustrated in figure 1 as a prior art rolling bearing structure, comprise an outer ring 11, one inner rings, 12, one retainers 14, wherein be provided with rolling element 13 between this outer ring 11 and the inner ring 12, rolling element 13 is connected by retainer 14.
Yet existing rolling bearing usually has a shortcoming, and its rolling element is normally formed by high-intensity Bearing Steel manufacturing.When bearing bore heavy load or bump load, the bearing race rigidity contact of rolling element and contact with it was easy to form fatigue damage, thereby causes bearing failure.
Summary of the invention
The technical problems to be solved in the utility model is existing bearing roller when bearing heavy load or bump load, forms fatigue damage easily, thereby causes bearing failure.
For solving the problems of the technologies described above, rolling bearing of the present utility model comprises: an outer ring, one inner ring and a retainer, wherein be provided with rolling assembly between this outer ring and the inner ring, rolling assembly is connected by retainer, and this rolling assembly comprises a rolling hub that rolls cover and support this rolling cover.
Rolling bearing of the present utility model wherein rolls and is arranged with cavity, can pour gas in the cavity.
Rolling bearing of the present utility model, the cover that wherein rolls is to be formed by the elastic material manufacturing.
Rolling bearing of the present utility model, the cover that wherein rolls is to be formed by rubber, nylon or special teflon manufacturing.
Rolling bearing of the present utility model, the hub that wherein rolls further includes support.
Compared with prior art, rolling bearing of the present utility model, when it bears high capacity or bump load, because rolling assembly is not that rigid material forms, thereby it can produce a certain amount of distortion and be difficult for causing rolling element and raceway to produce fatigue damage and cause bearing failure, and therefore rolling bearing of the present utility model can be applied to use under the various load environment.
Rolling bearing of the present utility model also has the following advantages, owing to adopt elastic material, the manufacture cost of roller will obviously reduce, and has simplified manufacturing process simultaneously again.And can realize the adjusting of bearing clearance by adjusting to gas atmosphere in the cover that rolls.
Description of drawings
Innovation and creation claimed at this and/or that describe will be set forth further combined with one exemplary embodiment.These one exemplary embodiment are specifically set forth with reference to the accompanying drawings.These embodiments will not constitute restriction of the present utility model, and the close similar structure of label representative is wherein arranged in a plurality of accompanying drawings, and accompanying drawing is not necessarily drawn according to actual ratio, wherein:
Fig. 1 is the structural representation of prior art rolling bearing.
Fig. 2 is the structural representation of the utility model rolling bearing.
Fig. 3 is the structure for amplifying schematic representation of the utility model rolling assembly.
Fig. 4 is the cover structure for amplifying schematic representation that rolls in the utility model rolling assembly.
Fig. 5 is a rolling hub structure for amplifying schematic representation in the utility model rolling assembly.
Embodiment
Please refer to Fig. 2, is according to the concrete rolling bearing of setting forth of an embodiment of the present utility model.This rolling bearing comprises an outer ring 21, one inner rings 22 and a retainer 24, wherein is provided with rolling assembly 23 between this outer ring 21 and the inner ring 22, and rolling assembly 23 is connected by retainer 24.
Please further with reference to figure 3, this rolling assembly 23 further comprises a rolling hub 232 that rolls cover 231 and support this rolling cover 231.Wherein, formed differently by the manufacturing of rigid bearing steel with the prior art rolling element, rolling in present embodiment cover 231 can be formed such as using rubber, nylon, special teflon etc. to manufacture by the elastic material manufacturing.
Please refer to Fig. 4, further disclose the structure of this rolling cover 231, it can be made by elastic material, in addition, the structure of establishing cavity in the cover 231 that rolls can also be fabricated to, the cavity inside of rolling cover 231 can pour pressurized gas when using, thereby makes the cover 231 that rolls can produce certain deformation after bearing very high capacity or bump load.
Further with reference to figure 5, be the structural representation of present embodiment rolling hub 232 please, this rolling hub 232 is formed by rigid material, such as being formed by Bearing Steel or structural steel manufacturing.Rolling hub 232 can be the round structure of a hollow, and its inside also can be provided with support 233 in order to strengthen the intensity of rolling hub.
When using the utility model rolling bearing, especially when bearing bears high capacity or bump load, because when rolling assembly 23 bears load, thereby it can produce a certain amount of distortion and can be difficult for causing rolling element and raceway rigidity friction-produced tired and cause bearing failure, and therefore rolling bearing of the present utility model can be applied to use various load environment under.
Rolling bearing of the present utility model also has the following advantages, owing to adopt elastic material, the manufacture cost of roller will obviously reduce, and has simplified manufacturing process simultaneously again.And can realize the adjusting of bearing clearance by adjusting to gas atmosphere in the cover that rolls.
Though the utility model only is described with regard to some one exemplary embodiment, these descriptions should only not be construed as limiting as example.In the scope of appended claims record, do not breaking away under the utility model spirit and scope situation, various variations all are possible.
