Abstract
The utility model provides a closed wheel pair for mining vehicles, which belongs to the technical field of mine transportation. The closed wheel pair for mining vehicles adopts a clamping ring of a shaft shoulder, a check ring which is used for the shaft, a metallic sealing ring sleeve and a sealing ring with a rubber framework; the sealing ring is also provided with a casing; the utility model also adopts the method that a groove with certain angle is arranged on the outer ring of the sealing ring sleeve to prevent contamination from entering. The utility model causes the structure of the wheel pair for the mining vehicles to be better reasonable, the manufacture technology is better simple, and simultaneously, the service life of the wheel pair for the mining vehicles can be improved. The utility model replaces the disadvantages that a traditional shaft end is fixed by circular nuts, and the other end can not be tightly sealed by a triangular pressing cover and a labyrinth-typed felt. The utility model is an ideal closed wheel pair for the mining vehicles.
Description
The utility model provides a kind of mine car hooded impeller right, belongs to transportation technology field, mine.
At present, transportation a large amount of one ton of tramcar wheel that uses in China mine are to still prolonging the designing technique with the fifties Soviet Union, its complex structure, and the bearing felt poor performance, service life is low, maintenance capacity is big, make difficulty, lost efficacy seriously.It is right that our factory in 1987 once grinds the institute's NGCC type of having developed wheel with the Shanghai coal, though structurally done bigger improvement, because of 310 special bearing out of reach designing requirements can't be used.M1 type dedicated sealing member is oversize, and hub inner hole structure shop characteristic is poor, makes difficulty is installed, and uses circular nut not too reliable at the axle head fixed type bearing, causes to be difficult to promote the use of.
The purpose of this utility model is that to design a kind of mine car hooded impeller right, can improve mine car service life, and simultaneously simple in structure, maintenance capacity is little.
It is right that the utility model has designed a kind of mine car hooded impeller of being made up of with back-up ring, tramcar wheel mine car axle, shaft block ring, bearing, outer separator, inner spacing collar, seal ring, sealing snare, hole.It with common tramcar wheel to different be to have substituted raw ore axletree end nut with shaft shoulder collar, shaft shoulder collar is two semicircle circles, its collar inside caliper is in the collar groove of mine car axle, outside journal axle is used with back-up ring for axis to a rectangular channel is arranged.Axially adorn bearing along the mine car axle, the bearing other end tightens with the standard back-up ring with the hole then with sealing snare and seal ring sealing, has replaced tramcar wheel to traditional triangle gland and the mode that is screwed.The sealing snare is a zinc-plated annulus made from steel pipe or smart cast tube, and the annulus periphery has one 60 ° of grooves in case dirt enters, and is pressed into the purpose made seal ring in the annulus week.
The utility model has the advantages that: rational in infrastructure, technology is simple, saved spring triangle stage clip lid, wheel boring, inside and outside labyrinth felt oil seal, joint bolt to structure than former tramcar wheel manufacturing erection work, tramcar wheel is to improving service life more than three times, reduced manufacturing cost, few maintenance, even do not have maintenance.
Accompanying drawing is that wheel is to the mounting structure scheme drawing.
Below in conjunction with accompanying drawing the utility model is further described:
The mine car hooded impeller is to being made of with back-up ring (2), wheel (1) mine car axle (6), shaft shoulder collar (10), shaft block ring (9), bearing (8), outer separator (7), inner spacing collar (11), seal ring (4), sealing snare (3), hole.Adopt shaft shoulder collar (10) to substitute raw ore axletree end nut, shaft shoulder collar (10) is two semicircle circles, and the collar inside caliper is in the collar groove of mine car axle, and outside journal axle is used for fixing shaft block ring (9) to a rectangular channel is arranged.Axially adorn bearing along the mine car axle, bearing (8) other end tightens with the standard back-up ring with the hole then with seal ring (4) and sealing snare (3) sealing, has replaced tramcar wheel to traditional triangle gland and the mode that is screwed.Sealing snare (3) is a zinc-plated annulus made from steel pipe or smart cast tube, and the annulus periphery has one 60 ° of grooves in case dirt enters, and is pressed into purpose made seal ring (4) in the annulus week, and sealing circle (4) is the rubber seal that has galvanized metal shell and band skeleton.
Claims (2)
1, a kind of mine car hooded impeller is right, by wheel (1), hole back-up ring (2), mine car axle (6), outer separator (7), bearing (8), inner spacing collar (11), shaft block ring (9) is formed, it is characterized in that: the wheel axle head adopts shaft shoulder collar (10) fixing, shaft shoulder collar (10) is two semicircle circles, the collar inside caliper is in the collar groove of mine car axle, outside journal axle is to a rectangular channel is arranged, be used for fixing shaft block ring (9), the other end of bearing (8) seals with the rubber seal (4) of band galvanized metal shell and band skeleton, the cylindrical place of seal ring (4) is inlaid with sealing snare (3), and tightens with standard back-up ring (2) with the hole.
2, mine car hooded impeller according to claim 1 is right, it is characterized in that: sealing snare (3) periphery has one 60 ° of grooves.
