Along with the high speed development of automobile industry and supporting industries concerned thereof, each MANUFACTURER and the quality of user to car load or component product are also proposed higher requirement, current automobile hub bearing dust-proof, sealing configuration imperfection, multi-form leakage fat phenomenon is mostly there is and seal ring comes off in the process used, the problems such as locking, and easily cause dust easily to infiltrate bearing, lubrication runs off because of High Temperature Rotating, thus cause bearing to lose efficacy early stage, working life shortens, customer responsiveness is strong, thus client to be met and the raising of the market demand to hub bearing technology is very important.
Model utility content
The technical problems to be solved in the utility model is to provide provides a kind of rational in infrastructure, rotates flexibly, has the Dustproof combined sealing double row angular contact hub bearing of good dust-proof and sealing effect.
In order to solve the problem existing for background technique, the utility model have employed following technological scheme: a kind of Dustproof combined sealing double row angular contact hub bearing, comprise bearing inner race, bearing outer ring, retainer, steel ball and dust sealing assembly, inner side between bearing inner race and bearing outer ring is located at by described retainer and steel ball, end between bearing inner race and bearing outer ring is located at by described dust sealing assembly, described dust-proof sealing device comprises Sealing, dust slinger and support frame, described dust slinger is close proximity to bearing inner race side, support frame is close proximity to bearing outer ring side, described Sealing is between dust slinger and support frame, the top of described Sealing is wrapped in internal surface and the end of support frame, described Sealing is provided with the first lip, second lip, 3rd lip and the 4th lip, the first described lip, second lip and the 3rd lip are connected to the internal surface of dust slinger respectively, described 4th lip and dust slinger end abutment.
By adopting above-mentioned technological scheme; be conducive to dust-proof, the sealing that greatly increase this hub bearing; thus when keeping the lubricating grease of Bearing inner in use can not run off; namely it is kept to rotate flexibility; protect the dust in the bearing external world or harmful gas to enter bearing cavity simultaneously, in case cause damage to bearing, and achieve less friction torque; efficiently solve locking phenomenon, thus its working life can be extended.
Further setting of the present utility model: described dust slinger and bearing inner race are interference fit, described support frame and bearing outer ring are interference fit, and the first lip, the second lip and the 3rd lip on described dust slinger and described Sealing are interference fit.
By adopting above-mentioned technological scheme, the installation of Sealing, dust slinger and support frame can be made more stable rationally, to improve dust-proof sealing device dust sealing effect further.
Further setting of the present utility model: described Sealing is made up of nitrile rubber material.
By adopting above-mentioned technological scheme, because nitrile rubber has excellent oil resistant, wear-resisting and heat resistance, operating ambient temperature can be higher, can avoid lubricating the phenomenon disappeared, and forwards dynamic flexibility with retainer shaft.
Further setting of the present utility model: described dust slinger is through plating zinc on surface process.
By adopting above-mentioned technological scheme, by zinc-plated for dust slinger process being made it have good lustrous surface, level and smooth and rust-proofing, corrosion resistance, thus make dust slinger more durable.
Further setting of the present utility model: the inner side ring wall of described bearing inner race two side ends notch portion is set to arcuate structure, and the inner side ring wall of bearing inner race is near the largest diameter of port.
By adopting above-mentioned technological scheme, the structure of bearing inner race more being rationalized, the installation of bearing inner race can be made more convenient simultaneously.
The beneficial effects of the utility model are: the utility model is by improving dust sealing assembly, and structure is more rationalized, and make it rotate more flexible, have good dust-proof and sealing effect, thus are conducive to extending its working life.
