The model utility content
The utility model provides a kind of tapered roller bearing unit of nut check structure, it mainly is that to solve the inner ring assembling ground of existing in prior technology tapered roller bearing more insecure, come off easily, and the seal ring that adopts is too simple, automobile in use, dust, muddy water enter into the inside of bearing unit easily, it is higher to leak the fat rate, thereby makes friction torque increase inner ring and outer ring excessive wear, cause the life-span of product shorter, the technical problem of the bigger grade of automobile energy consumption.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The tapered roller bearing unit of a kind of nut check structure of the present utility model, comprise flange plate, flange plate is provided with bolt, be fixed with long inner ring, short inner ring by nut on the described flange plate, long and short inner ring is provided with the outer ring outward, all be provided with retainer between long and short inner ring and the outer ring, all be provided with a row tapered roller on two retainers.By nut inner ring is locked on the flange plate, can prevents that inner ring from deviating from use, be easy to assembling, can adopt riveting locking.Can scribble happy safe glue on the nut, prevent to get loose.
As preferably, be connected with the perforate drawn cup needle roller bearing by protective housing in the described flange plate.Conical wheel hub bearing unit and flange plate assembly, and the perforate drawn cup needle roller bearing is fitted in the inside of flange plate.
As preferably, the long inner ring between described two row tapered rollers is provided with gear ring, and gear ring is connected with sensor.Adopt built-in gear ring, utilize wire harness abs sensor technology, improve the stability of durability, resistance to shock and the electric property of abs sensor.
As preferably, be provided with interior dust cover and the inner seal ring of section between the inner of described outer ring and long inner ring for " L " shape, be attached with inner seal liner on the inner seal ring, extend sealing lip interference contact on the inner seal liner on the internal surface of interior dust cover.Be provided with cavity between inner seal ring and the interior dust cover, be provided with Sealing in the cavity, seal body is attached on the inner seal ring, and seal body is extended 3 sealing lip interference contacts on the internal surface of interior dust cover.Therefore the internal surface place of dust cover in extended three sealing lips of seal body all are blocked in by the dustproof lip in three roads, can prevent effectively that dust, muddy water from entering bearing inside.
As preferably, be provided with outer dust cover and the exterior seal ring of section between the outer end of described outer ring and short inner ring for " L " shape, be attached with outside seal may on the exterior seal ring, extend on the outside seal may on the internal surface that the sealing lip interference contacts dust cover outside.Be provided with cavity between exterior seal ring and the outer dust cover, be provided with Sealing in the cavity, seal body is attached on the exterior seal ring, and seal body is extended on the internal surface that 3 sealing lip interference contact dust cover outside.Extended three sealing lips of seal body all are blocked in the internal surface place of outer dust cover, therefore by the dustproof lip in three roads, can prevent effectively that dust, muddy water from entering bearing inside.
Therefore, the utility model utilizes nut that inner ring is fixed on the flange plate, be easy to assembling, make inner ring can not deviate from use, and between outer ring and flange plate, adopted three lip combined type labyrinth seal structures, the lip interference design of sealing lip, can reduce and leak the fat rate, improve anti-muddy water infiltration capability, reduce friction torque, reduce the automobile energy consumption, simple and reasonable for structure.
