Description
Technical field
The invention relates to design bearing technical field, specially refer to a kind of uniform section ultra-thin wall angular contact ball bearing and carry sealing configuration.
Background technique
Bearing requires its sealing to be divided into contact-type and contactless two kinds of forms according to applying working condition, what the present invention selected is noncontact seal, what the noncontact seal of bearing adopted in the past is dust cover form, because uniform section ultra-thin-wall bearing structure is compact, limited space, its dust cover is difficult to processing, up-to-standard rate is low, cost is high, adds foozle, makes the unequal sealing effect that causes of its sealing place one circumferential clearance amount poor.
As can be seen here, there is defect in the sealing of above-mentioned existing uniform section ultra-thin wall angular contact ball bearing, and is urgently further improved.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but have no for a long time applicable design always, by development, completed, and common product does not have appropriate structure to address the above problem, this is obviously the problem that the anxious wish of relevant dealer solves.
Summary of the invention
The object of the invention is to overcome the defect that existing noncontact seal bearing exists, and the uniform section ultra-thin wall angular contact ball bearing that a kind of new structure is provided carries sealing configuration, technical problem to be solved is to make it simple in structure, and low cost of manufacture reaches good sealing effect.
The object of the invention is to realize by the following technical solutions.The invention provides a kind of uniform section ultra-thin wall angular contact ball bearing and carry sealing configuration, comprising: outer ring, inner ring and rolling element, the internal diameter middle part of outer ring is provided with circular arc raceway groove; Wherein: it is the fluted body that one is long and the other is short that outer ring is limit, two ends, and extend towards the direction of inner ring on its limit, two ends, one end of inner ring external diameter is cylndrical surface, the other end of inner ring external diameter is slope, the jointing place of cylndrical surface and slope is provided with circular arc raceway groove, long limit, one end, outer ring is positioned at slope place, and short limit, one end is positioned at place, cylndrical surface, and the height of outer ring equals the height of inner ring.
Object of the present invention also can be applied to the following technical measures to achieve further.
Preferably, aforesaid uniform section ultra-thin wall angular contact ball bearing carries sealing configuration, between the limit, two ends of the cylndrical surface of wherein said inner ring and slope and outer ring, leaves space.
Preferably, aforesaid uniform section ultra-thin wall angular contact ball bearing carries sealing configuration, and wherein said rolling element is between the circular arc raceway groove and the circular arc raceway groove of inner ring outer radius at outer ring internal diameter middle part.
By technique scheme, uniform section ultra-thin wall angular contact ball bearing of the present invention carries sealing configuration and at least has following advantages and beneficial effect: from the above, bearing outer ring is processed as fluted body, both increased the intensity of ultra-thin-wall bearing outer ring, reduced the distortion in manufacture process and in testing process, guaranteed again limit, two ends diameter dimensional accuracy and with the concentricity of outer ring external diameter, make seal clearance uniformity consistent with gap length, not only solve the problem of dust cover difficult processing but also reduced cost of production, both guaranteed the effect of sealing, meet again user's requirement.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification, and for above and other object of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
