Description
Technical field
The utility model relates to a kind of bearing for automobile absorber, especially a kind of bearing with sealing configuration.
Background technique
Automobile absorber is arranged between automotive suspension and car body, and attenuation vibration when automobile is hit the generation vibration, improve vehicle running smoothness and travelling comfort.When vibration damper is hit, elastic element will produce very large torsion by compression, and the vibration damper bearing turns to rotation by this torsion and avoided the fretting wear of elastic element and its counterpart, can allow in addition motor turning more smooth-going laborsaving.Because vibration damper is installed on the wheel side, when rainy day or carwash, muddy water is easy to splash to vibration damper, therefore the vibration damper bearing is also proposed to higher seal request, and the design of automotive light weight technology is considered and the restriction of vibration damper peripheral space own, make the design space limited of vibration damper bearing, adopt independently Sealing, to increase bearing moment, and size minor structure complexity certainly will increase manufacture difficulty and make cost increase; The vibration damper bearing is axial arranged in addition, makes bearing in operation process, and bulk deposition is in the bearing bottom under Action of Gravity Field for lubricating grease, and on long-time rear bearing, the raceway circle is lubricated insufficient, affects the bearing endurance quality.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides that a kind of favorable sealing property, structure are more simple, longer service life and manufacture difficulty is low and cost the is low bearing with sealing configuration.
To achieve these goals, the technical solution adopted in the utility model is: a kind of bearing with sealing configuration, comprise inner ring, outer ring and the retainer between inner ring and outer ring, retainer is provided with the pocket hole, pocket is embedded with rolling element in hole, it is characterized in that: described retainer and inner ring, retainer and outer ring are and are tightly connected.
In said structure, between the outer wall of retainer and inner ring, be tightly connected, and be tightly connected between the inwall of retainer and outer ring and make bearing can effectively prevent that in the process of running extraneous dust, muddy water are from the inner corrosion bearing of invading of bearing.
As further setting of the present utility model, described retainer comprises interior ring, waist and outer shroud, and in described retainer, ring is provided with sealing lip a, and the retainer waist is provided with sealing lip b, and sealing lip a is connected with interior ring outer wall, and sealing lip b is connected with the outer ring inwall.
In said structure, sealing lip a in retainer on ring contacts with inner ring, the sealing lip b of retainer waist contacts with outer ring, in the process of bearing operation, said structure can prevent that grease from revealing and thereby bearing early failue is avoided in the intrusion of muddy water dust effectively, this sealing configuration substitutes independent sealed, has reduced bearing moment, has reduced manufacture difficulty and has optimized cost.Retainer waist and interior ring are supported on respectively on outer ring and inner ring in addition, have avoided the retainer inside and outside wall to contact with the integral body of inside and outside circle, have reduced bearing moment.
As further setting of the present utility model, described inner ring is provided with outward edge, described outer ring is provided with outer flanging, described outward edge is provided with isolation pad towards the end face of outer ring, one end of isolation pad is compressing the inner ring outward edge, and the other end of isolation pad is provided with the shackle link that is compressing described outer flanging, and the other end of described isolation pad relative orientation rolling element is provided with bound edge, bound edge is coated on the outside of inner ring, isolation pad, outer ring, and inner ring, isolation pad, outer ring are into a single integrated structure by the bound edge riveted.
In said structure, inner ring, outer ring, isolation pad and bound edge form contact seal and become one structure by technique for riveting, can effectively prevent that when bearing operation extraneous dust and muddy water are from the outside intrusion of bearing.
As further setting of the present utility model, the inwall at place, described pocket hole becomes the ramp structure with arc, and inclined-plane is towards described outer ring inwall.
In said structure, the inwall in retainer pocket hole becomes the effect that has spatula with the ramp structure of arc when the bearing operation, when bearing operation, this ramp structure is constantly scraped following grease in the pocket hole, coordinates the rolling element rotation, and grease is constantly up supplemented, thereby make bearing lubrication more abundant, reduce bearing moment, and improve bearing usability and life-span
As further setting of the present utility model, described retainer is provided with spaced groove towards the end face of outer ring inwall, and described groove is positioned at the end face at place, both sides, pocket hole.
In said structure, the groove of retainer setting has alleviated the weight of retainer, has reduced bearing moment and has reduced the fretting wear of retainer, improves bearing usability and life-span.
Below in conjunction with accompanying drawing, the utility model is further described.
The accompanying drawing explanation
Accompanying drawing 1 is the utility model bearing sectional drawing;
Accompanying drawing 2 is the utility model retainer schematic appearance;
Accompanying drawing 3 is the utility model retainer internal surface, outer surface structure schematic diagram.
Embodiment
The specific embodiment of the utility model bearing with sealing configuration as Figure 1-3, comprise inner ring 1, outer ring 2 and the retainer 3 between inner ring 1 and outer ring 2, retainer 3 is provided with pocket hole 31, be embedded with rolling element 4 in pocket hole 31, retainer 3 is provided with sealing mechanism with inner ring 1,2 joints, outer ring.Be tightly connected between the outer wall of retainer 3 and inner ring 1, and be tightly connected between the inwall of retainer 3 and outer ring 2 and make bearing can effectively prevent that in the process of running extraneous dust, muddy water are from the inner corrosion bearing of invading of bearing.
As shown in Figure 1, above-mentioned retainer 3 comprises interior ring, waist and outer shroud, and the interior ring of retainer 3 is provided with sealing lip a32, and retainer 3 waists are provided with sealing lip b33, and sealing lip a32 is connected with inner ring 1 outer wall, and sealing lip b33 is connected with outer ring 2 inwalls.Sealing lip a32 on the interior ring of retainer 3 contacts with inner ring 1.The sealing lip b33 of retainer 3 waists contacts with outer ring 2, in the process of bearing operation, said structure can prevent that grease from revealing and thereby bearing early failue is avoided in the intrusion of muddy water dust effectively, this sealing configuration substitutes independent sealed, reduced bearing moment, reduced manufacture difficulty and optimized cost.Retainer 3 waists and interior ring are supported on respectively on outer ring 2 and inner ring 1 in addition, have avoided retainer 3 inside and outside walls to contact with the integral body of inner ring 1, outer ring 2, have reduced bearing moment.
