Abstract
The utility model discloses a bush bearing dustproof device, comprising a slewing journal and a transmission shaft. A slewing journal shield ring is arranged on the slewing journal and a transmission shaft shield ring is arranged on the transmission shaft. A gasket ring which is sulfuretted on the transmission shaft shield ring and is connected with the slewing journal shield ring is arranged between the slewing journal shield ring and the transmission shaft shield ring. The bush bearing dustproof device is of a special structure that the shield ring and the gasket ring are added to the prior slewing journal and the transmission shaft. The impurity such as sewage, dust and so on can be well prevented from entering, therefore the bush bearing is protected and the service life of the bush bearing is improved. At the same time, the bush bearing dustproof device design has the advantages of simple structure, convenience for assembly, fastening and reliability and low cost.
Description
Technical field
The utility model relates to a kind of dust guard, especially relates to a kind of hub bearing dust guard that is used on the truck drive shaft.
Background technique
The hub bearing that is used for the spindle endoporus at present press-fits in the knuckle endoporus, and the transmission shaft shoulder block just is pressed on the bearing inner race, and there is certain clearance between transmission shaft shoulder block and the knuckle endoporus, thereby the dust cover that causes this hub bearing is directly exposed in the external environment condition, in daily use, impurity such as muddy water, dust is easy to enter and directly contacts with hub bearing, and then shortened working life of hub bearing, cause adverse influence also for the performance of car load.
The model utility content
Technical problem to be solved in the utility model provides a kind of hub bearing dust guard, and this device can effectively prevent entering of impurity such as muddy water, dust in process used in everyday to reach, thereby reaches the purpose of avoiding the hub bearing premature failure.
For solving the problems of the technologies described above, the technical solution of the utility model is, this hub bearing dust guard comprises knuckle and transmission shaft, be respectively equipped with the knuckle back-up ring on knuckle and the transmission shaft, the transmission shaft back-up ring, between described knuckle back-up ring and transmission shaft back-up ring, be provided with the seal ring that sulfuration is connected with knuckle back-up ring elasticity on the transmission shaft back-up ring, stretch out the sealing lip of clearance channel between two sealing knuckle back-up rings and the transmission shaft back-up ring on the seal ring, be provided with sulfuric horizon between seal ring and the transmission shaft back-up ring, sulfuric horizon is connected with the transmission shaft back-up ring with seal ring respectively, and the fit system of transmission shaft back-up ring and transmission shaft is an interference fit; The knuckle back-up ring is nested in the endoporus of knuckle, and with the fit system of knuckle endoporus be interference fit.
A kind of hub bearing dust guard with above-mentioned special construction; back-up ring and seal ring only on original knuckle and transmission shaft, have been increased; just can be good at preventing entering of impurity such as muddy water, dust, thus the working life that can protect hub bearing and then improve hub bearing.The design of this a kind of hub bearing dust guard simultaneously possesses advantage reliable and with low cost simple in structure, easy to assembly, fastening.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the partial schematic sectional view of a kind of hub bearing dust guard of the utility model.
Fig. 2 is that cross-sectional schematic is amplified in the part of a kind of hub bearing dust guard of the utility model.
Embodiment
The partial sectional view of a kind of hub bearing dust guard shown in Figure 1, comprise knuckle and transmission shaft, be respectively equipped with knuckle back-up ring 3 on knuckle 1 and the transmission shaft 2, transmission shaft back-up ring 4, between knuckle back-up ring 3 and transmission shaft back-up ring 4, be provided with the seal ring 5 that sulfuration is connected with knuckle back-up ring 3 elasticity on transmission shaft back-up ring 4, stretch out the sealing lip 6 of clearance channel between two sealing knuckle back-up rings 3 and the transmission shaft back-up ring 4 on the seal ring 5, be provided with sulfuric horizon between seal ring 5 and the transmission shaft back-up ring 4, sulfuric horizon is connected with transmission shaft back-up ring 4 with seal ring 5 respectively, transmission shaft back-up ring 4 is an interference fit with the fit system of transmission shaft 2, during assembling, sealing lip 6 and periphery thereof are coated with lubricating grease with the wearing and tearing of minimizing with other component, the material of sealing lip 6 adopts nitrile butadiene rubber, thereby can compensate certain wear extent automatically by the extension of self; Knuckle back-up ring 3 is nested in the endoporus of knuckle 1, with the fit system of the endoporus of knuckle 1 be interference fit.
Shown in Figure 2 is the local amplification view of the cooperating structure of a kind of knuckle of hub bearing dust guard and knuckle back-up ring, transmission shaft and transmission shaft back-up ring and transmission shaft back-up ring and sealing lip.
Certainly; seal arrangement is not limited to the utility model and establishes back-up ring and sealing lip on knuckle and transmission shaft; can also be other device, all drop within the protection domain of the present utility model in the modification of establishing seal arrangement on knuckle and the transmission shaft for sealing.
