Abstract
The utility model relates to the bearing technical field, particularly to a double-seal bearing with spherical outside surfaces. The double-seal bearing is provided with a bearing outer ring, a bearing inner ring, a rolling body and a seal ring, wherein the rolling body and the seal ring are arranged between the bearing outer ring and the bearing inner ring, the seal ring is positioned on two sides of the rolling body, a dust cap is arranged at the outer side of the seal ring and provided with a dustproof framework which is fixed on the outer surface of the bearing inner ring, rubber lips are arranged at the upper end of the dustproof framework, and the rubber lips are in contact with the end surface of the bearing outer ring. The double surfaces of the bearing both adopt the double-seal structure, thereby efficiently preventing external gross particulates and impurities from permeating into the bearing, improving the sealing performance of the bearing, prolonging the service life, and better suiting the nasty work environment.
Description
Technical field
The utility model relates to technical field of bearings, relates in particular to a kind of double-sealing bearing with spherical outside surface.
Background technique
General bearing seal performance all requires very high, and particularly in bad working environment, sealability requires higher.In order to improve the sealability of bearing, the general form that adopts dual face seals, but after long-term the use, because extraneous big particle impurity enters, rub for a long time with seal ring, seal ring is caused damage, sealability descends, big particle impurity and then infiltrate rolling element in the bearing internal injury bearing reduces whole bearing working life greatly.
The model utility content
The technical problems to be solved in the utility model is: a kind of double-sealing bearing with spherical outside surface is provided, has the double density structure, can stop effectively that extraneous big particle impurity infiltrates in the bearing, improves the sealability of bearing, to adapt to worse working environment.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of double-sealing bearing with spherical outside surface, have bearing outer ring, bearing inner race, rolling element and seal ring, rolling element and seal ring are arranged between bearing outer ring and the bearing inner race, seal ring is positioned at the both sides of rolling element, the arranged outside of seal ring has dust cover, and dust cover has dustproof skeleton, and dustproof skeletal fixation is on the outer surface of bearing inner race, dustproof skeleton upper end is provided with rubber lip, and rubber lip contacts with the bearing outer ring end face.
Described dustproof skeleton and bearing inner race outer surface interference fit, promptly dustproof skeleton contacts tightr with the bearing inner race outer surface, improve its sealability.
The beneficial effects of the utility model are; The two-sided double sealing structure that is of this bearing can stop effectively that extraneous big particle impurity infiltrates in the bearing, improves the sealability of bearing, and long service life more adapts to bad working environment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Wherein: 1. bearing outer ring, 2. bearing inner race, 3. rolling element, 4. seal ring, 5. dust cover, 51. dustproof skeletons, 52. rubber lips.
Embodiment
As shown in Figure 1, a kind of double-sealing bearing with spherical outside surface, have bearing outer ring 1, bearing inner race 2, rolling element 3 and seal ring 4, rolling element 3 and seal ring 4 are arranged between bearing outer ring 1 and the bearing inner race 2, and seal ring 4 is positioned at the both sides of rolling element 3, and the arranged outside of seal ring 4 has dust cover 5, dust cover 5 has dustproof skeleton 51, dustproof skeleton 51 is fixed on the outer surface of bearing inner race 2, and dustproof skeleton 51 upper ends are provided with rubber lip 52, and rubber lip 52 contacts with bearing outer ring 1 end face.This dust cover 5 both contacted with bearing inner race 2 outer surfaces, contacted with bearing outer ring 1 end face again, thereby had constituted double-layer sealing structure with seal ring 4, made extraneous big particle impurity can't enter inner rolling element 3 working portions of bearing, had promoted the sealability of bearing.
Claims (2)
