Abstract
The utility model relates to a kind of double-row-ball hub-bearing unit of novel channel structure, comprise flange plate, flange plate is provided with outer ring, inner ring, bolt, retainer, exterior seal ring, gear ring, sensor, it is characterized in that described outer ring forms outside raceway groove and inner side raceway groove, article two, install steel ball in raceway groove, the dimensional parameters of two raceway grooves is inconsistent.The utility model has and improves Bearing inner stressing conditions and improve bearing life function.
Description
(1) technical field
The utility model relates to a kind of automobile bearing unit, the hub-bearing unit of the unequal dimensional parameters structure of especially a kind of Bearing inner double channel.
(2) background technique
The inner two channel dimensions parameters of conventional vehicle hub-bearing unit are identical, and inner stressing conditions is poor, time larger for wheel center and bearing centre deviation, cause inner two channels carry power inequalities, occur that early fatigue causes bearing failure.And conventional wheel hub unit rib factor design can meet the requirement of carrying normal axial load, but when carrying larger axis is needed to power for some, the low meeting of rib coefficient causes rolling element Contact Ellipse to ascend shoulder block, and cause bearing life to decline, therefore appropriate design rib coefficient is needed, ensure that bearing can bear larger thrust load, technology capability and temperature increase requirement can be met again.
(3) model utility content
The utility model provides a kind of double-row-ball hub-bearing unit of novel channel structure, its object is to solve the inner two channel dimensions parameters of existing product identical, inner stressing conditions is poor, bearing early failue, and the hub rib coefficient existing for prior art is difficult to bear the technical problem of larger axis to load.
For this reason, the utility model takes following technological scheme: a kind of double-row-ball hub-bearing unit of novel channel structure, comprise flange plate, flange plate is provided with outer ring, inner ring, bolt, retainer, exterior seal ring, gear ring, sensor, it is characterized in that described outer ring forms outside raceway groove and inner side raceway groove, article two, install steel ball in raceway groove, the parameter of two raceway grooves is inconsistent.
In the raceway groove that ditch footpath is large, steel ball number is greater than the little raceway groove in ditch footpath more than the large milling radius of the little raceway groove in ditch footpath or ditch footpath.
Be placed on more than the steel ball number of inner side raceway groove 1 ~ 2 of the steel ball number of outside raceway groove.
The radius of curvature of outside raceway groove is larger than the radius of curvature of inner side raceway groove.
Be provided with step between described outside raceway groove and inner side raceway groove, and pass through circular sliding slopes.
Described retainer is opening bowl shaped structure.
The utility model has the following advantages:
1. Bearing inner double channel is designed to two kinds of unequal dimensional parameters, improves Bearing inner stressing conditions, the side large in ditch footpath increases steel ball number or adds larger radius of curvature to increase bearing capacity, and reasonable distribution bearing capacity is conducive to prolongation bearing working life.
2. optimize outer ring inner retaining side coefficient by theory calculate, increase bearing axial carrying capacity.
3. between Liang Gou, design ledge structure, and with circular sliding slopes, effectively avoid stress to concentrate, elimination sharp angle effect and double annealing are on the impact of quality of product.
4. retainer is designed to opening bowl shaped structure, has and be convenient to steel ball assembling, save space, oil storage, avoid and the function such as seal ring interference.
(4) accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Fig. 2 is outer ring schematic diagram
Fig. 3 is outer ring cross-sectional view
Fig. 4 is the cross-sectional view of interior retainer
In figure: retainer, 7-exterior seal ring, 8-gear ring, 9-sensor, 10-bolt 11-raceway groove 12-step in 1-outer ring, 2-inner ring, 3-flange plate, 4-steel ball, the outer retainer of 5-, 6-.
(5) embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to the double-row-ball hub-bearing unit of a kind of novel channel structure shown in Fig. 1-4, comprise flange plate, flange plate 3 is provided with outer ring 1, inner ring 2, bolt 10, interior retainer 6 and outer retainer 5, exterior seal ring 7, gear ring 8, sensor 9, outer ring 1 forms outside raceway groove and inner side raceway groove, article two, the dimensional parameters installing steel ball 4, two raceway grooves 11 in raceway groove is inconsistent.The radius of curvature being placed on steel ball number 1 ~ 2 or the outside raceway groove more than the steel ball number of inner side raceway groove of outside raceway groove is larger than the radius of curvature of inner side raceway groove.Be provided with step 12 between outside raceway groove and inner side raceway groove, and by circular sliding slopes, retainer is opening bowl shaped structure.
What the utility model adopted remains bead structure, but 1 liang, outer ring raceway groove parameter is unequal, and steel ball number or steel ball size are also unequal.Have and improve inner stressing conditions raising bearing life function.Can two channel dimensions be unequal as seen from Figure 2, be designed with step between two raceway grooves, and with circular sliding slopes, effectively avoid stress to concentrate and sharp angle effect.The feature of Fig. 4 opening bowl-type retainer is convenient to steel ball assembling, without the need to any moulds of industrial equipment and efficiency is high, also has in addition and save space, oil storage, avoid the functions such as interference.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
