Abstract
The utility model relates to a kind of novel without rib automobile bearing, comprise outer ring, inner ring, seal ring, retainer and some rollers, seal ring has two, two seal rings are separately positioned on the two ends between outer ring and inner ring, each roller is evenly arranged along the periphery circumference of inner ring, each roller is all arranged between outer ring and inner ring by retainer, the cross section that the periphery of roller is provided with along roller axis direction is leg-of-mutton limited ring, the described plane at limited ring place and the axes normal of roller, described outer ring and inner ring are respectively equipped with the position of roller contact the annular groove mated with limited ring, the radius of the radius limited ring corresponding thereto of described annular groove is equal.This novel without rib automobile bearing by built-in limited ring, instead of traditional rib to arrange, reduce the width at bearing two ends, also make the long moment stress check calculation of rib single in traditional design become multiple spot shaft strength, ensure that the stability of whole bearing structure, extend working life.
Description
Technical field
The utility model relates to field of bearings, and particularly one is novel without rib automobile bearing.
Background technique
Automobile thrust-bearing is inner is all generally adopt retainer to carry out spacing to roller, and adopt the rib of inner ring both sides to carry out axially support to roller, along with industrial expansion, miniaturization and the demand become more meticulous more and more higher, at the inner ring of bearing, two ribs are set, although the effect of bearings can be played, but also strengthen the width of bearing, increase the space shared by bearing, and but the rib of bearing both sides carries out the support of axial force, the moment that monolateral rib can be made to bear is comparatively large, and what need rib to design is very abundant.
Model utility content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provides a kind of novel without rib automobile bearing.
The utility model solves the technological scheme that its technical problem adopts: a kind of novel without rib automobile bearing, comprise outer ring, inner ring, seal ring, retainer and some rollers, described seal ring has two, two seal rings are separately positioned on the two ends between outer ring and inner ring, each roller is evenly arranged along the periphery circumference of inner ring, each roller is all arranged between outer ring and inner ring by retainer, the cross section that the periphery of described roller is provided with along roller axis direction is leg-of-mutton limited ring, the described plane at limited ring place and the axes normal of roller, described outer ring and inner ring are respectively equipped with the position of roller contact the annular groove mated with limited ring, the radius of the radius limited ring corresponding thereto of described annular groove is equal.
In order to make the rolling of roller more smooth, the tangent line that described outer ring is tangent with inner ring and roller is respectively equipped with the hemispherical groove that quantity is identical with roller, on described roller, corresponding hemispherical groove is provided with the quantity cross section along roller axis direction identical with hemispherical groove is semicircular circular groove, is provided with steel ball between described hemispherical groove and circular groove.
As preferably, described limited ring is isosceles triangle along the cross section in roller axis direction, and the drift angle in cross section is 30 °.
As preferably, described limited ring has 7, and described retainer is arranged on the two ends of roller near two seal rings.
As preferably, the distance between described outer ring and inner ring equals the diameter of roller.
The beneficial effects of the utility model are, this novel without rib automobile bearing by built-in limited ring, instead of traditional rib to arrange, reduce the width at bearing two ends, also the long moment stress check calculation of rib single in traditional design is made to become multiple spot shaft strength, ensure that the stability of whole bearing structure, extend working life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the novel structural representation without rib automobile bearing of the present utility model;
In figure: 1. outer ring, 2. inner ring, 3. seal ring, 4. retainer, 5. roller, 6. limited ring, 7. steel ball.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of novel without rib automobile bearing, comprise outer ring 1, inner ring 2, seal ring 3, retainer 4 and some rollers 5, described seal ring 3 has two, two seal rings 3 are separately positioned on the two ends between outer ring 1 and inner ring 2, each roller 5 is evenly arranged along the periphery circumference of inner ring 2, each roller 5 is all arranged between outer ring 1 and inner ring 2 by retainer 4, the cross section that the periphery of described roller 5 is provided with along roller 5 axial direction is leg-of-mutton limited ring 6, the described plane at limited ring 6 place and the axes normal of roller 5, described outer ring 1 is respectively equipped with the position that inner ring 2 contacts with roller 5 annular groove mated with limited ring 6, the radius of the radius limited ring 6 corresponding thereto of described annular groove is equal.
In order to make the rolling of roller 5 more smooth, the tangent line that described outer ring 1 is tangent with roller 5 with inner ring 2 is respectively equipped with the quantity hemispherical groove identical with roller 5, the cross section along roller 5 axial direction that on described roller 5, corresponding hemispherical groove is provided with quantity identical with hemispherical groove is semicircular circular groove, is provided with steel ball 7 between described hemispherical groove and circular groove.
As preferably, described limited ring 6 is isosceles triangle along the cross section of roller 5 axial direction, and the drift angle in cross section is 30 °.
As preferably, described limited ring 6 has 7, and described retainer 4 is arranged on the two ends of roller 5 near two seal rings 3.
As preferably, the distance between described outer ring 1 and inner ring 2 equals the diameter of roller 5.
Compared with prior art, this novel without rib automobile bearing by built-in limited ring 6, instead of traditional rib to arrange, reduce the width at bearing two ends, also the long moment stress check calculation of rib single in traditional design is made to become multiple spot shaft strength, ensure that the stability of whole bearing structure, extend working life.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
