Abstract
An automobile hub bearing for novel seal groove buckle structure, belongs to auto parts and components.The utility model comprises bearing outer ring, bearing inner race, retainer, rolling element and R shape rubber seal, rolling element is installed between bearing outer ring and bearing inner race by retainer, after bearing outer ring and bearing inner race have assembled, form an annular groove between the two, seal ring press-fits in this annular groove, skeleton is provided with in seal ring, skeleton is fixed in seal ring as insert part forming injection moulding, seal ring interference press-fits in annular groove, seal ring is posted by the inner headed face of bearing outer ring and the periphery of bearing inner race, make seal ring between bearing outer ring and bearing inner race, form an airtight space, described bearing outer ring inwall is provided with a sealing locking slot, a part for seal ring is flush-mounted in sealing locking slot, a spring is set with outside seal ring.The seal ring that the utility model solves existing automobile hub bearing easily produces axial displacement, the problem that sealing effect is bad.
Description
Technical field
The utility model belongs to auto parts and components field, especially relevant with a kind of automobile hub bearing of novel seal groove buckle structure.
Background technique
Automobile hub bearing comprises bearing outer ring, bearing inner race, retainer, rolling element and seal ring, bearing outer ring is connected with automotive suspension, brake disc and the steel ring of bearing inner race and automobile are connected, rolling element is installed between bearing outer ring and bearing inner race by retainer, seal ring is arranged between bearing outer ring and bearing inner race, usually closely cooperate being formed among the lip of seal ring press-in protecting cover, because automobile running makes hub bearing work in the environment of vibration of being everlasting, time one is long, seal ring easily produces position skew, affect the sealing effect of seal ring, cause silt, the impurity such as dust enter hub bearing, affect the working life of hub bearing.
Model utility content
The seal ring that the purpose of this utility model is intended to overcome existing automobile hub bearing easily produces axial displacement, the defect that sealing effect is bad, provide a kind of can fixed seal ring position, seal groove buckle structure that sealing effect is good automobile hub bearing.
For this reason, the utility model is by the following technical solutions: a kind of automobile hub bearing of novel seal groove buckle structure, comprise bearing outer ring, bearing inner race, retainer, rolling element and seal ring, rolling element is installed between bearing outer ring and bearing inner race by retainer, after bearing outer ring and bearing inner race have assembled, form an annular groove between the two, seal ring press-fits in this annular groove, it is characterized in that, described seal ring is R shape rubber ring, skeleton is provided with in seal ring, skeleton is fixed in described seal ring as insert part forming injection moulding, seal ring interference press-fits in described annular groove, seal ring is posted by the inner headed face of bearing outer ring and the periphery of bearing inner race, make seal ring between bearing outer ring and bearing inner race, form an airtight space, described bearing outer ring inwall is provided with a sealing locking slot, after seal ring loading puts in place, because seal ring has elastic force, a part for seal ring is made to be flush-mounted in described sealing locking slot, axial limiting is carried out to seal ring, it is made to produce axial displacement, described seal ring is by suit one spring, by the Exposure of the tension force automatic compensation sealing of spring, ensure good sealability.
Use the utility model can reach following beneficial effect: 1, by press-fiting a R shape seal ring in the annular groove of bearing outer ring and bearing inner race, the skeleton as insert part forming is fixed in the injection moulding of sealing circle, make the skeleton of seal ring not yielding, ensure the usability of seal ring; 2, by arranging a sealing locking slot on bearing outer ring inwall, can carry out spacing to the axis of seal ring, its position is not offset, improve sealing effect, effectively can prevent the impurity such as silt, dust from entering hub bearing inside, improve the sealing of bearing; 3, by being set with a spring outward at seal ring, by the Exposure of the tension force automatic compensation sealing of spring, good sealability can be ensured.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Fig. 2 is the close-up schematic view sealing locking slot described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As depicted in figs. 1 and 2, the utility model comprises bearing outer ring 4, bearing inner race 1, retainer 2, the seal ring 6 of rolling element 3 and R shape rubber, rolling element 3 is installed between bearing outer ring 4 and bearing inner race 1 by retainer 2, after bearing outer ring 4 and bearing inner race 1 have assembled, form an annular groove between the two, seal ring 6 press-fits in this annular groove, skeleton 5 is provided with in seal ring 6, skeleton 5 is fixed in described seal ring 6 as insert part forming injection moulding, seal ring 6 interference press-fits in described annular groove, seal ring 6 is posted by the inner headed face of bearing outer ring 4 and the periphery of bearing inner race 1, make seal ring 6 between bearing outer ring 4 and bearing inner race 1, form an airtight space, the inwall of described bearing outer ring 4 is provided with a sealing locking slot 8, after seal ring 6 loading puts in place, because seal ring 6 has elastic force, a part for seal ring 6 is made to be flush-mounted in described sealing locking slot 8, axial limiting is carried out to seal ring 6, it is made to produce axial displacement, described seal ring 6 is by suit one spring 7, by the Exposure of the tension force automatic compensation sealing of spring 7, ensure good sealability.
