Abstract
The invention discloses a kind of hub unit with Double seal ring, the hub unit includes hub shell, central siphon and inner bearing and outer bearing between hub shell and central siphon, inner frame oil sealing and outer-frame oil seal are further respectively had on inner bearing, outer bearing, inner bearing inner ring with central siphon be equipped with together with inner seal ring, outer bearing inner ring with central siphon equipped with together with exterior seal ring.By the inner ring of outer bearing with central siphon be equipped with together with exterior seal ring, prevent gear oil from entering in hub-bearing unit grease lubrication system, effectively prevent the mixing of bearing grease and gear oil, it is ensured that the cleaning of grease, extends the service life of hub-bearing unit.
Description
Technical field
The invention belongs to heavy truck axle hub bearing unit application field, more particularly to a kind of wheel hub list with Double seal ring
Member.
Background technology
At present, found in production practices, for the wheel end system of the hub-bearing unit using grease lubrication, its grease lubrication
System（As shown in the figure）It is by inner frame oil sealing 4, inner bearing 3, hub shell 6, outer-frame oil seal 10, outer bearing 11 and interior outer bearing
The X oil sealings 12 of joint form.The lubrication of inside and outside bearing is exactly to be lubricated by the quantitative grease for being filled into the inside, is moistened in this set
In sliding system, internal diameter and the central siphon 1 and outside diameter of inside and outside bearing are that small―gap suture coordinates, the X oil sealings 12 and two between inside and outside bearing
Between bearing inner race in technique there are it is poorly sealed the problem of, the dust and gear oil that make have an opportunity to enter in lubricating system
Go, traditional solution method is only equipped with " O " type sealing ring 2 at the inner ring of inner bearing with central siphon." O " type sealing ring 2
Presence, the problem of only alleviating poorly sealed caused by the small―gap suture at inner bearing inner ring and central siphon.Due to outer bearing
The outside diameter of inner ring internal diameter and central siphon 1 is also that small―gap suture coordinates, and the locking nut 9 and gasket 8 for being pressed in outer bearing also have gap, central siphon
The gear oil to come at 1 endoporus just soaks here, and gear oil easily moistens from the small―gap suture of outer bearing and central siphon into unit fat
In sliding system.
The content of the invention
The purpose of the present invention is what is realized by following skill scheme, which includes hub shell, central siphon and is located at
Inner bearing and outer bearing between hub shell and central siphon, further respectively have inner frame oil sealing and dermoskeleton on inner bearing, outer bearing
Frame oil sealing, inner bearing inner ring with central siphon be equipped with together with inner seal ring, it is characterised in that in the inner ring and central siphon of outer bearing
Place is equipped with one of exterior seal ring.
Preferably, the exterior seal ring is round section joint ring.
During assembling, after a whole set of bearing unit is attached on central siphon, then exterior seal ring, gasket, locking nut are put successively.Make
Hub-bearing unit has the structure of double " O " shape sealing rings.
Beneficial effects of the present invention：By the inner ring of outer bearing with central siphon be equipped with together with exterior seal ring, prevent gear
Oil is entered in hub-bearing unit grease lubrication system, effectively prevents the mixing of bearing grease and gear oil, it is ensured that grease
Cleaning, extends the service life of hub-bearing unit.
Brief description of the drawings
The embodiment that the invention will now be described in detail with reference to the accompanying drawings
Fig. 1 is the installation diagram of the present invention
In figure：1st, central siphon 2, inner seal ring 3, inner bearing 4, inner frame oil sealing 6, hub shell 7, exterior seal ring 8,
Gasket 9, locking nut 10, outer-frame oil seal 11, outer bearing.
Embodiment
As shown in Figure 1, the hub unit includes hub shell 6, central siphon 1 and the interior axle between hub shell 6 and central siphon 1
3 and outer bearing 11 are held, inner frame oil sealing 4 and outer-frame oil seal 10 are further respectively had on inner bearing 3, outer bearing 11, in interior axle
Hold the 3 inner ring inner seal ring 2 together with being equipped with central siphon 1, outer bearing 11 inner ring with central siphon 1 equipped with together with outside " O " shape
Sealing ring 7.During assembling, after a whole set of bearing unit is attached on central siphon 1, then exterior seal ring 7, gasket 8, locking nut are put successively
9.Make hub-bearing unit that there is the structure of Double seal ring.
Claims (2)
1. a kind of hub unit with Double seal ring, which includes hub shell, central siphon and positioned at hub shell and central siphon
Between inner bearing and outer bearing, inner frame oil sealing and outer-frame oil seal are further respectively had on inner bearing, outer bearing, in interior axle
The inner ring held with central siphon be equipped with together with inner seal ring, it is characterised in that outer bearing inner ring with central siphon be equipped with together with outside it is close
Seal.
