Abstract
The invention provides a bearing with self sealing. The bearing comprises a bearing outer ring and a bearing inner ring; a steel ball and a retainer are arranged between the bearing outer ring and the bearing inner ring; the axial dimension of the bearing inner ring is least 3mm smaller than that of the bearing outer ring; the bearing outer ring is provided with a stepped hole; the stepped hole comprises a small hole and large holes respectively arranged on the two ends of the small hole; the hole wall of the small hole is provided with an annular steel ball roller path, and a step part of the small hole with each large hole is provided with an annular groove; a pair of annular sealing covers are arranged between the bearing outer ring and the bearing inner ring, and are arranged on the two sides of the steel ball respectively; each annular sealing cover comprises an annular rubber part and an annular skeleton; each annular rubber part is sleeved by the corresponding annular skeleton, and the annular rubber part and the corresponding annular skeleton are bonded together; the inner side of each annular rubber part is provided with three layers of contact lip which is firmly contacted with the outer side surface of the bearing inner ring; and the periphery outer edge of each annular skeleton is provided with a bending part embedded into the corresponding annular groove.
Description
Technical field
The present invention relates to a kind of bearing carrying sealing.
Background technique
General bearing enclose width is equal, the axle jump ring that the bearing being arranged on axle head moves axially owing to being provided with restriction bearing at axle head, axle head is caused axially to exceed bearing, can affect the design and installation of other component in some occasion, the existing life-span carrying the bearing seal of sealing is also undesirable.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of bearing carrying sealing.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bearing carrying sealing, comprise bearing outer ring and bearing inner race, be provided with steel ball and retainer between described bearing inner race and bearing outer ring, the axial dimension of described bearing inner race is at least less than the axial dimension 3mm of bearing outer ring; Described bearing outer ring has step hole, and step hole comprises aperture and divides the macropore being located at aperture two ends, and aperture hole wall offers annular steel ball rolling channel, and the step place of macropore and aperture offers annular groove; The annular sealing cover laying respectively at steel ball both sides for a pair is provided with between described bearing outer ring and bearing inner race, annular sealing cover comprises ring-shaped rubber part and ring skeleton, ring skeleton to be sleeved on ring-shaped rubber part and bonding with it, the inner side of described ring-shaped rubber part has the contact lip of three circles and bearing inner race outer side surface close contact, and the circumferential outer of ring skeleton is provided with the bending part of embedded rings connected in star.
The invention has the beneficial effects as follows: the present invention is arranged on axle head axle jump ring when fixing, the free end that axle head stretches out bearing inner race can not exceed the outer ring of bearing, solves the problem proposed in background technique; Ring-shaped rubber part of the present invention has the contact lip of three circles and bearing inner race outer side surface close contact, and sealing life is relatively long, and sealing effect is also better.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
In figure: 1. bearing outer ring; 2. bearing inner race; 3. steel ball; 4. annular sealing cover; 41. ring-shaped rubber parts; 42. ring skeletons; 5. contact lip.
Embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of bearing carrying sealing as shown in Figure 1, comprises bearing outer ring 1 and bearing inner race 2, is provided with steel ball 3 and retainer between described bearing inner race 2 and bearing outer ring 1.
The axial dimension of described bearing inner race 2 is less than the axial dimension 3mm of bearing outer ring 1;
Described bearing outer ring 1 has step hole, and step hole comprises aperture and divides the macropore being located at aperture two ends, and aperture hole wall offers annular steel ball rolling channel, and the step place of macropore and aperture offers annular groove;
The annular sealing cover 4 laying respectively at steel ball 3 both sides for a pair is provided with between described bearing outer ring 1 and bearing inner race 2, annular sealing cover 4 comprises ring-shaped rubber part 41 and ring skeleton 42, ring skeleton 42 to be sleeved on ring-shaped rubber part 41 and bonding with it, the inner side of described ring-shaped rubber part 41 has the contact lip 5 of three circles and bearing inner race 2 outer side surface close contact, and the circumferential outer of ring skeleton 42 is provided with the bending part of embedded rings connected in star.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
