Description
[technical field]
The utility model belongs to technical field of bearings, relates to a kind of automobile silicon oil filled fan clutch release bearing unit.
[background technique]
At present, identical bilabiate or three lip seal structures are all adopted in the both sides of the release bearing unit of known automobile silicon oil filled fan clutch, the shortcoming of this structure is: because the operating conditions of the both sides of release bearing is different, one side only need prevent that lubricating grease from leaking and common extraneous dust, impurity is invaded bearing, and opposite side will prevent that not only lubricating grease from leaking, and need prevent that the extremely strong silicone oil of permeability from penetrating into bearing, therefore, when identical common bilabiate or three lip seal structures are used in both sides, will make bearing that seal failure often takes place, cause occurring bearing early failue, greatly reduce the working life of bearing, both wasted resource, befouling environment again.
[model utility content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of energy to guarantee that sealing is reliable, rotation is flexible and the hub heat radiation is good, can effectively stop leaking of release bearing unit lubricating grease, and can stop the intrusion of outside dirt and silicone oil, automobile silicon oil filled fan clutch release bearing unit with long product lifecycle and simple installation advantage.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of automobile silicon oil filled fan clutch release bearing unit, adopt the double-row angular contact bal bearing structure, comprise outer ring, inner ring, rolling element and seal ring, all there is the biserial raceway groove inner ring and outer ring, in the biserial raceway groove, be respectively equipped with rolling element, below rolling element, be provided with the inner ring of the bear inner ring grooved railway that adapts with rolling element; Between outer ring raceway and bear inner ring grooved railway, the outside of rolling element is provided with retainer, the inner ring periphery is provided with the rib that adapts with rolling element, the line of action between rolling element and the raceway groove is along the wrapping angle that has 25 °-35 ° between point of contact common normal line direction and channel plane; How much symmetrical center line of bearing two row steel ball symmetrical center line and bearing integral have certain distance, and the promising satisfied difference in both sides requires and the seal ring of setting.
Be provided with the sealing configuration of a RunddichtringO in a side of described inner ring and outer ring.
Opposite side in described inner ring and outer ring is provided with the sealing configuration of two RunddichtringOs.
A described RunddichtringO is skeleton rubber three lip seal circles, its flexible outer endless belt interference fit is a RunddichtringO master lip, the secondary lip of a RunddichtringO and one one RunddichtringO radial seal lip of " people " font in outer ring raceway outside flute profile endless belt being provided with in interior week of skeleton.
The secondary lip slight interference of one RunddichtringO is matched with the little rib of the smooth external diameter of inner ring, a RunddichtringO master lip and the sliding contact of inner ring external diameter rib axial sides, and the little Spielpassung of RunddichtringO footpath labiad is in the smooth large-flange of inner ring.
Described two RunddichtringOs are skeleton rubber bilabiate seal ring, and its outer endless belt interference fit is in outer ring raceway outside endless belt, at the secondary lip of two RunddichtringO master lips, two RunddichtringOs that seal ring is " people " font that is provided with in interior week of skeleton; The equal slight interference of the secondary lip of two RunddichtringO master lips and two RunddichtringOs is matched with the external diameter rib smooth with inner ring, and contacts with inner ring external diameter rib slip around.
The beneficial effects of the utility model are: adopt the sealing configuration of different sealing performance, reduced extraneous foreign matter and invaded bearing inside, stablized the bearing working play, improved product working life; Product has 30 ° wrapping angle, has axially and bearing capacity radially; Before seal ring is pressed into the release bearing unit, inject a kind of low noise, high temperature resistant, lubricating grease that greasy property is good to inside, release bearing unit, can make its lifelong selflubricating; The utility model is installed in the automobile silicon oil filled fan clutch, links, reduce automobile silicon oil filled fan clutch assembly number of spare parts, alleviated the gross weight of parts with motor output driven shaft and fan hub; The seal ring of same-action can not prevent the intrusion of extraneous dust, impurity and silicone oil, has significantly improved bearing working life, reached simplify install, the purpose of protection environment.
