Abstract
The utility model discloses a three-row-roller four-point contact type hub bearing comprising a bearing inner ring and a bearing outer ring, wherein a rolling path is formed by the outer side wall of the bearing inner ring and the inner side wall of the bearing outer ring; the rolling path is internally provided with a bearing retainer; the bearing retainer is provided with three rows of rollers; the bearing retainer comprises two sub retainers which are distributed at the two sides of the rolling path; two rows in the three rows of the rollers are respectively distributed in the sub retainers; the sub retainers respectively extend towards the other sub retainer to form a middle clamping part; and the residual one row of the rollers are arranged in the middle clamping part. The hub bearing disclosed by the utility model is additionally provided with one row of the rollers and the whole bearing space is not increased, so that the installation of the hub bearing is the same as before; two rows of steel balls bear a load under the condition that swerving and the like of a car are subjected to axial impact force; and the rated load of the hub bearing is improved and the rated load is improved by more than 20% when being compared with that of the previous two rows of the hub bearings.
Description
Technical field
The utility model relates to technical field of bearings, is specifically related to 4 contact-type hub bearings of a kind of three row roller.
Background technique
Hub bearing is to be applied to the Automobile shaft place to be used for load-bearing and the component of accurate guiding are provided for the rotation of wheel hub, not only bears thrust load but also bear radial load, is the important component part of carload and rotation.Present existing hub bearing generally comprises bearing outer ring and bearing inner race, is provided with raceway between bearing outer ring and bearing inner race, is provided with retainer in raceway, is provided with two row in retainer along the roller of bearing axial distribution.Only have two row rollers in this hub bearing, in the situation that the bearing space structure is limited, the radial and axial bearing capacity of bearing can not the largest optimization Design and manufacture, in the situation that automobile turnings etc. are subject to axial impact force, only have a row steel ball to bear, easily make damage of bearings, lost efficacy in advance.
Summary of the invention
The purpose of this utility model is: for the deficiencies in the prior art, the utility model provides the three row roller that a kind of bearing axial carrying capacity is stronger, working life is higher 4 contact-type hub bearings.
To achieve these goals, the utility model has adopted following technological scheme:
4 contact-type hub bearings of a kind of three row roller, comprise bearing inner race and bearing outer ring, form a raceway between the outer side wall of described bearing inner race and the madial wall of bearing outer ring, be provided with retainer in described raceway, described retainer is provided with three row rollers, comprise that two branches are at minute retainer of raceway both sides on described retainer, in described three row rollers two row are distributed in respectively in minute retainer, retainer was respectively towards another minute retainer extension in described minute, clamping part in the middle of forming, described residue one row roller is arranged in middle clamping part.
As preferably, be provided with a minute maintenance groove in described minute retainer.After adopting above-mentioned preferred version, the better effects if of the grip roller of of the present utility model minute retainer.
As preferably, minute maintenance groove of described minute retainer leans on a side of another minute retainer towards another minute retainer extension, form a minute maintenance groove and extend the end, kept in described minute groove extend the end with another minute retainer minute keep a groove extend the end jointly form in the middle of clamping part, the roller of described middle column is arranged at two minutes and keeps between groove extension end.After adopting above-mentioned preferred version, the roller of middle column of the present utility model need not to increase in addition retainer, middle the clamping part clamping that utilizes minute retainer at two row roller places, raceway side to extend to form, and structure is simpler, and while clamping effect is better.
As preferably, be provided with backbone sealing ring between described bearing outer ring and bearing inner race, described backbone sealing ring is separately positioned on the both sides of retainer.After adopting above-mentioned preferred version, the better tightness of hub bearing of the present utility model.
Hub bearing of the present utility model has been set up a row roller, but do not increase whole bearing space, make the installation of hub bearing with the same before, automobile turning etc. is subject in the situation of axial impact force, two row steel ball bearing loads are arranged, improved the load rating of hub bearing, load rating has improved more than 20% than two original row hub bearings.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the cross-sectional view that the utility model embodiment is positioned at the roller place at place, raceway both sides;
Fig. 3 is the cross-sectional view that the utility model embodiment is positioned at the roller place of raceway middle column.
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, embodiment of the present utility model is 4 contact-type hub bearings of a kind of three row roller specifically, comprise bearing inner race 1 and bearing outer ring 2, the outside of bearing outer ring 2 is provided with bearing outer ring flange 21, and bearing inner race 1 outside is provided with bearing inner race flange 11 away from a side of bearing outer ring flange 21.Form a raceway 3 between the madial wall of the outer side wall of bearing inner race 1 and bearing outer ring 2, be provided with retainer 4 in raceway 3, retainer 4 is provided with three row rollers 5.Comprise that two branches are at minute retainer 41 of raceway 3 both sides on retainer 4, in three row rollers 5 two row are distributed in respectively in minute retainer 41, divide retainer 41 respectively towards another minute retainer 41 extensions, clamping part 42 in the middle of forming, a remaining row roller 6 are arranged in middle clamping part 42.Divide and be provided with a minute maintenance groove 411 in retainer 41.Minute retainer 41 minute keep groove 411 by another minute a retainer side of 41 towards another minute retainer 41 extend, form a minute maintenance groove and extend end 412, minute keep groove extend end 412 with another minute retainer 41 minute keep a groove to extend that end 412 is common forming in the middle of clamping parts 42, the roller 5 of middle column is arranged at two minutes and keeps groove to extend between end 412.Be provided with backbone sealing ring 6 between bearing outer ring 2 and bearing inner race 1, backbone sealing ring 6 is separately positioned on the both sides of retainer 4.
The working principle of the working principle of 4 contact-type hub bearings of three row rollers of the present utility model and the hub bearing of prior art is basic identical, difference is: hub bearing of the present utility model has been set up a row roller 5, has improved the load degree of hub bearing.
