Abstract
The utility model relates to a novel sealing tramcar wheel pair which consists of a wheel shell, a bearing, an internal distance sleeve, an external distance sleeve, an end cover and an obturating ring. The novel sealing tramcar wheel pair mainly solves the problem of poor sealing effect of the original tramcar wheel pair, and is characterized in that the novel sealing tramcar wheel pair adopts the O-shaped rubber obturating ring and a framework typed rubber oil seal, and is applicable to mine transportation equipment and belongs to the field of mining machine.
Description
Technical field
It is right that the utility model relates to a kind of novel seal mine tram wheel, and it is right with wheel particularly to be applied to down-hole, mine mine car.Belong to the mining machinery field.
Background technique
At present, down-hole, mine mine car, particularly the underground mine use mine tram wheel is right, generally is made up of wheel shell, bearing, distance cover, oil immersion sealing cord, triangle baffle plate, wheel shaft, oil hole etc.Bearing Installation in the wheel shaft two ends, is closed tightly with locking nut.In the wheel columella bearing of packing into then, oil immersion sealing cord travelling expenses are compressed by the triangle baffle plate on the axle in the bearing outside, reach the effect to bearing seal.Because be to rely on the triangle baffle plate to compress the tarred rope crush seal, in case distortion of triangle baffle plate or tarred rope travelling expenses are loosening, outside grit etc. will enter in the bearing support, influence the normal rotation of bearing and lubricate, thereby influence the normal operation of mine tram wheel.
The model utility content
It is right that the purpose of this utility model provides a kind of novel seal mine tram wheel, and it can not only guarantee that the sealing of mine tram wheel is reliable, and easy accessibility.
The utility model is achieved in that in wheel shell inboard, distance cover, outer distance cover, bearing are installed in wheel axle one end successively in the bearing, the sealing of O type rubber seal is arranged between the surface of contact in end cap and the wheel shell, the sealing of U type skeleton rubber seal ring is also arranged between seal ring frame and the bearing, the sealing of rubber oil seal with reinforce and wool felt is arranged between end cap and the seal ring frame.End cap and wheel shell Bolt Connection are pressed on the seal ring frame on the bearing.Guarantee like this to be isolated from the outside in the bearing bore.The not contaminated purpose of bearing and lubricant oil.And such structure convenient disassembly.Because adopt such scheme, it is contaminated to reach bearing and lubricant oil, and simple in structure.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the utility model sealed structure chart.
Embodiment
In Fig. 1, there is the bearing support chamber that bearing 10 is installed wheel shell 1 inboard.Bearing 10, interior distance cover 12, outer distance cover 11, seal ring frame 3, seal ring 4,7, skeleton rubber seal 5, wool seal felt 6 are installed on the axletree 5 successively, and by 13 lockings of grooved nut.End cap 2 is pressed on the wheel shell 1 by six interior hexagonal spiral shell fillister head screws, also is provided with oil hole 16 on the wheel shell 1, and airtight by screw 17.
In Fig. 2, wool seal felt 6, reinforced seal 5 respectively with end cap 2 and seal ring frame 3, seal ring frame 3 and bearing 10 contact seals.
The utility model working procedure is such: wheel shell 1 inner chamber is equipped with bearing 10, interior distance cover 12, outer distance cover 11, seal ring frame 3, seal ring 4,7, rubber oil seal with reinforce 5, wool seal felt 6 successively, and the two ends of axletree 5 are installed in opposite directions, and by 13 lockings of grooved nut.With end cap 2 said structure spare is pressed on the wheel shell 1 by six hexagon socket cap head screws again.Wheel shell 1 is provided with oil hole 16, and lubricant oil injects the wheel shell with oil gun thus and is equipped with in the cavity of bearing.
Claims (2)
1. a novel seal mine tram wheel is right, in the wheel shell, bearing, interior distance cover, outer distance cover, end cap are assembled successively, it is characterized in that: between end cap and wheel shell and seal ring frame and bearing, oil hole puts aperture with outer distance and is communicated with the O RunddichtringO respectively.
2. novel seal mine tram wheel according to claim 1 is characterized in that: rubber oil seal with reinforce one side contacts with bearing, and opposite side and seal ring bridge joint touch, and the seal ring frame is pressed on the wheel shell by end cap.
