Abstract
The utility model discloses a bearing device of a skip car wheel, and the bearing device comprises a shaft and a bearing, wherein the front end of the bearing is provided with a thrust ring, the periphery of the thrust ring is provided with a bearing end cover, and a sealing ring which is made of a polytetrafluoroethylene material is arranged between the bearing end cover and the thrust ring. The sealing ring has high strength, the deformation phenomenon is unlikely to occur when the wheel rotates, dust can be effectively prevented from entering the wheel, and the seize phenomenon of the wheel when the skip car runs can be prevented.
Description
Technical field
The utility model relates to a kind of bearing means of truck wheel.
Background technique
Truck is the instrument that draws material to blast furnace in the iron works; Be the key equipment of blast furnace, control is had relatively high expectations to truck wheel axial movement value, adopts mechanical mazy type+wool felt combination seal form in the existing truck design bearing between front and back wheels bearing air cover and spindle nose; Not wear-resisting, the sealing extreme difference; Because truck is ceaselessly carrying out the work of material loading, discharging; Dust is very big in the process of material loading, discharging; If the sealability that this moment, wheel bearing passed through between lid and spindle nose is bad; A large amount of dusts will get into lubricant oil between inside wheel and bearing and mix and form particle, and time one length is stuck under the situation of bearing oil starvation in the time of will causing the wheel running, has a strong impact on the safety in production of blast furnace.
The model utility content
The utility model provides a kind of seal ring intensity high truck wheel bearing arrangement in order to overcome the deficiency of existing technology.
To achieve these goals; The utility model adopts following technological scheme: a kind of bearing means of truck wheel, comprise axle, bearing, and the front end of said bearing is provided with thrust ring; The thrust ring periphery is provided with bearing (ball) cover, is provided with the seal ring of teflon material between bearing (ball) cover and the thrust ring.
Further, said thrust ring comprises ring body and flange, and said seal ring is placed in the ring body periphery.
Further, said seal ring is a rotary shaft lip seal.
The beneficial effect of the utility model is: the utility model seal ring intensity is high, and wheel can not cause its metaboly in the running, has prevented that effectively dust from getting into inside wheel, the wheel phenomenon that is stuck when stopping the truck running.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the utility model thrust ring.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme; To combine the accompanying drawing among the utility model embodiment below; Technological scheme among the utility model embodiment is carried out clear, complete description; Obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all should belong to the scope of the utility model protection.
Like Fig. 1, shown in Figure 2, a kind of bearing means of truck wheel comprises axle 4, bearing 6, end cap 7, and the front end of bearing 6 is equipped with thrust ring 3, and thrust ring 3 comprises ring body 31 and flange 32; Thrust ring 3 peripheries are provided with bearing (ball) cover 5; Through seal ring 2 sealings, sealing circle 2 is enclosed within ring body 31 peripheries of thrust ring 3 between bearing (ball) cover 5 and the thrust ring 3, because the effect of flange 32; Not only seal ring 2 is fixed firmly, prevented that also seal ring is extruded simultaneously; The sealing circle adopts rotary shaft lip seal, is processed by the teflon material, and its wear resistance is very high; Because the sealing intensity of seal ring is high, wheel can not cause its metaboly in the running, has prevented that effectively dust from getting into inside wheel, and the wheel phenomenon that is stuck has guaranteed the normal operation of truck when stopping the truck running.
