Description
Technical field
The utility model relates to a kind of bearing, is specifically related to a kind of main pin of automobile bearing.
Background technique
Existing main pin of automobile bearing, generally comprises blowout patche, seat ring, roller, outer casing.In the work of bearing, rolling element produces relative movement between the seat ring and blowout patche of bearing, then will inevitably produce phase mutual friction between moving body, after long-time use, heating and the wearing and tearing of rolling element, blowout patche, seat ring will inevitably be caused, then reduce the working life of bearing.Thus, in order to reducing friction resistance, the rate of wear slowing down bearing and control Bearing inner temperature rise, improve working life of bearing, the lubrication problem of bearing must be considered in the structural design of bearing, simultaneously in order to make bearing keep lubrication, also must consider the sealing of bearing.The bearing that sealability is higher, effectively can prevent dust, moisture, foreign matter etc. from entering Bearing inner, then can ensure the lubrication of oiling agent.
In the prior art, after the long-time use of most bearing, the sealability of seal element will inevitably be caused to reduce, friction between rolling element and track increases.Therefore, change seal element in time or add oiling agent to Bearing inner in time, just seeming very important.But all there is seal element and change the defects such as the interpolation difficulty of difficulty or oiling agent in the most of bearing existed at present.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of reasonable in design, sealability is high, seal element is easy to taking-up, bearing lubricant adds main pin of automobile bearing easily.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of main pin of automobile bearing, comprise blowout patche, seat ring, steel ball, blowout patche is provided with the first raceway, seat ring is provided with the second raceway, steel ball is arranged between the first raceway and the second raceway, blowout patche and seat ring outer rim are provided with outer casing, outer casing is provided with at least one tapped hole, tapped hole is provided with the knob cooperatively interacted with it, the seal ring cooperatively interacted with it is provided with between described blowout patche and seat ring, sealing circle is provided with the extension section that seal ring can be pulled out in blowout patche and seat ring, when seal ring takes out by needs, only need to apply the power pulled out to extension section, being separated of seal ring and bearing can be realized.In addition, the outer casing of described main pin of automobile bearing establishes at least one tapped hole, this tapped hole is used for adding oiling agent to Bearing inner, after oiling agent adds and terminates, availablely seals this tapped hole with the knob that tapped hole mates mutually.
As preferably, described tapped hole is evenly arranged on outer casing.Tapped hole is evenly arranged on outer casing, can further facilitates and add oiling agent to Bearing inner, meanwhile, also can ensure the even interpolation of bearing lubricant.
As preferably, described extension section is that the ring be arranged on seal ring is protruding, and described ring projection extends blowout patche and seat ring.Ring projection is extended blowout patche and seat ring, can further facilitate and the power pulled out is applied to extension section.
As preferred further, described ring projection is provided with open portion, and the shape of described open portion is identical with seal ring.When seal ring and blowout patche and race fit too closely time, when seal ring being pulled out by extension section, may comparatively require great effort, and very easily skid during force, in the open portion that the protruding upper mounted shape of ring is identical with seal ring, hand can be placed between seal ring and open portion during force, and by applying to ring projection the power that pulls out, very easily can to realize being separated of seal ring and bearing.
As preferably, described seal ring, extension section, open portion are made by elastic material.
As preferably, the cross-section lengths of described open portion is less than the distance between blowout patche and seat ring.When bearing and other component assemble, in the blowout patche that open portion and extension section can correspondingly be pressed into bearing and seat ring, then do not affect the assembling between bearing and other component.
As preferably, the radius of curvature of described first raceway and the second raceway is less than the diameter of steel ball.
As preferred further, the radius of curvature of described first raceway and the second raceway is 55 ~ 59% of steel ball size.When the radius of curvature of the first raceway and the second raceway is 55 ~ 59% of steel ball size, the tired working life of bearing can be extended, reduce the heating of bearing.
The utility model compared with the existing technology has the following advantages and effect:
1, main pin of automobile bearing described in the utility model, by the knob arranging tapped hole and cooperatively interact with tapped hole on outer casing, when needs add oiling agent to Bearing inner, only need knob to screw out, then avoid to be carried out by bearing integral dismantling loaded down with trivial details; 2, because bearing lubricant can in time and add easily, then effectively can reduce Bearing inner rolling element and the friction between blowout patche and seat ring, reduce the heating of Bearing inner; 3, the seal ring described in this practicality is provided with extension section, applies a pulling force to extension section, can realize being separated of seal ring and bearing, then makes the improvement of the sealing of bearing can be more for convenience; 4, main pin of automobile bearing described in the utility model, has higher fatigue life and working life.
