Abstract
The utility model discloses an automobile tension bearing. The automobile tension bearing comprises a bearing inner race, a bearing outer race, steel balls, a seal ring and a holder, wherein the bearing outer race is sleeved with the bearing inner race through the steel balls and the holder, the seal ring is arranged between the bearing inner race and the bearing outer race and is annular, an annular groove is formed on the seal ring and separates one end of the seal ring into a main lip and an auxiliary lip, a 'W'-type groove is formed on the bearing inner race, the main lip and the auxiliary lip of the seal ring are in interference fit with the 'W'-type groove, and an external seal groove of the bearing outer race and the excircle of the seal ring are in interference fit with each other. The 'W'-type groove are in interference fit with the main lip and the auxiliary lip of the seal ring, the external seal groove of the bearing outer race is in interference fit with the excircle of the seal ring, so that the seal ring is in a compression state and is tightly contacted with the bearing inner race and the bearing outer race, and a good sealing effect is obtained.
Description
Technical field
The utility model relates to a kind of bearing, especially the automobile tension wheel bearing.
Background technique
Present automobile tension wheel bearing adopts contact seal, easily generates a gap between seal ring and bearing, and sealing effect is bad, easily intakes, advances ash, causes inner steel ball oxidation and rusting to make it pivoting friction and increases, and the working life of bearing is shorter.
The model utility content
The technical problems to be solved in the utility model is expansion tightening wheel bearing seal poor effect and a kind of expansion tightening wheel bearing of good sealing effect is provided.
in order to achieve the above object, the technological scheme that the utility model provides is: a kind of automobile tension wheel bearing, comprise bearing inner race, bearing outer ring, steel ball, seal ring, retainer, this bearing outer ring passes through steel ball, retainer and bearing inner race socket, be provided with seal ring between bearing inner race and outer ring, it is circular that seal ring is, annular groove on seal ring is divided into main lip and secondary lip with the one end, bearing inner race is provided with " W " type groove, the main lip of seal ring and secondary lip and " W " type groove interference fit, the outer endless belt interference fit of the outer ring seal groove of bearing outer ring and seal ring.
The beneficial effects of the utility model are: on bearing inner race of the present utility model, the main lip of " W " type groove and seal ring, secondary lip adopt interference fit, the outer endless belt interference fit of the outer ring seal groove of bearing outer ring and seal ring, make seal ring be in compressive state, seal ring is tightr with contacting of bearing inner race, bearing outer ring, and the annular groove on seal ring makes main lip and secondary lip have more elasticity, can be tightr with the applying of " W " type groove, sealing effect is better.
Description of drawings
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the A place enlarged view of Fig. 1.
In figure: bearing outer ring 1, bearing inner race 2, steel ball 3, seal ring 4, retainer 5, annular groove 6, main lip 7, secondary lip 8, " W " type groove 9, outer ring seal groove 10, outer endless belt 11.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
as shown in Figure 1: a kind of automobile tension wheel bearing, comprise bearing inner race 1, bearing outer ring 2, steel ball 3, seal ring 4, retainer 5, this bearing outer ring 2 is by steel ball 3, retainer 5 and bearing inner race 1 socket, be provided with seal ring 4 between bearing inner race 1 and bearing outer ring 2, seal ring 4 is circular, annular groove 6 on seal ring 4 is divided into main lip 7 and secondary lip 8 with the one end, bearing inner race 1 is provided with " W " type groove 9, the main lip 7 of seal ring 4 and secondary lip 8 and " W " type groove 9 interference fit, the outer ring seal groove 10 of bearing outer ring 2 and outer endless belt 11 interference fit of seal ring 4, seal ring 4 is in steel ball 3 and retainer 5 environment of sealing.
Working principle of the present utility model is: " W " type groove 9 on the expansion tightening wheel bearing outer ring 2 of the utility model design and main lip 7, secondary lip 8 interference fit of seal ring 4, the outer ring seal groove 10 of bearing outer ring 2 and outer endless belt 11 interference fit of seal ring 4, make seal ring 4 be in compressive state, seal ring 4 is tightr with contacting of bearing inner race 1, bearing outer ring 2, and the annular groove on seal ring 46 makes main lip 7 and secondary lip 8 have more elasticity, can be tightr with 9 applyings of " W " type groove, sealing effect is better.
