Abstract
The utility model discloses a mining car wheel set, which comprises a pair of hubs and a connecting shaft connected with the hubs. Bearings and inner bushings arranged at two ends of the connecting shafts are connected with the hubs fittingly, the hubs are provided with oil injection holes, an inner dustproof cover is arranged on the inner side of each hub, a bearing stopper, a lock plate and lock screws are arranged at each end of the connecting shaft so as to fix each bearing, an outer dustproof cover is arranged on the outer side of each hub, a sealing ring is arranged between the outer dustproof cover and the hub, and the outer dustproof cover is fixed by a clamp ring arranged in a groove of the hub. The bearings can match with the connecting shaft well, the top surface of each outer dustproof cover is 2-3cm sunken on the outer side of the hub so that the outer dustproof cover can not be damaged by external force, foreign matters can not drop into the wheel set to damage the bearings, and the wheel set can not be in failure and service life of the wheel set can be prolonged. Meanwhile, as the outer dustproof covers are fixed by the clamp rings in the grooves of the hubs, the sealing rings are respectively arranged between each outer dustproof cover and each hub, and foreign matters can not drop into the bearings and the connecting shafts on the premise of guaranteeing normal operation states of the wheel set. Further, the mining car wheel set is simpler in structure and convenient in maintenance.
Description
Technical field:
The utility model relates to mine transportation equipment, specifically is that a kind of tramcar wheel is right.
Background technology:
Mine car is the main transportation device that adopt in the mine, and wherein tramcar wheel is to being the visual plant of mine car again, and the tramcar wheel that adopts is right at present, and general structure is comparatively complicated, the bearing felt poor performance, and service life is low, and maintenance capacity is big, and it is serious to lose efficacy.Its reason is provided with a grooved big nut and spring cotter and cooperates and lock bearing at the both ends of the right adapter shaft of tramcar wheel, because the position in hole is when assembling on open slot on the grooved big nut and the spring cotter, be difficult to fit like a glove, cause the tightness of bearing to be difficult to reach optimum regime, in use, because the wheel hub rotation direction changes at any time, the grooved big nut takes place loosening easily, thereby causes the inefficacy of equipment; The right outer cover of dust of tramcar wheel adopts screw directly to captive joint with wheel hub, because there is interface in mine rail, big to the right oscillating action of tramcar wheel in use, make outer cover of dust loosening and come off easily, and the side of outer cover of dust protrusion wheel hub, under the external force collision situation, damage easily outer cover of dust, also directly have influence on tramcar wheel right service life.In order to overcome above-mentioned technological deficiency, announced also that on Chinese patent multiple follow-on tramcar wheel is right, " mine car hooded impeller to " as the patent No. 95217769.2, adopt shaft shoulder collar to substitute grooved big nut on the adapter shaft exactly, the other end at bearing seals with sealing snare and seal ring, this tramcar wheel is to improving the mated condition of adapter shaft and bearing, the better seal effect is also arranged, but the part as outer cover of dust is still protruded the wheel hub side, be damaged equally easily, result of use is undesirable.
The utility model content:
The purpose of this utility model is a kind of simple in structure, and low cost of manufacture is convenient to maintenance, and the tramcar wheel that can effectively increase the service life is right.
In order to achieve the above object, this tramcar wheel is to comprising a pair of wheel hub and the adapter shaft that is connected wheel hub, two ends at adapter shaft are provided with bearing, inner covering and wheel hub are connected, wheel hub is provided with oil hole, oil hole exports corresponding inner covering, it is characterized in that: be provided with interior cover of dust in the inboard of wheel hub, interior cover of dust is fixedly connected on the wheel hub, in the end of adapter shaft the bearing catch is set, locking plate and lock screw fixed type bearing, cover of dust outside the arranged outside of wheel hub, be provided with seal ring between cover of dust and the wheel hub outside, be arranged on the fixing outer cover of dust of snap ring in the wheel hub groove.
In the adapter shaft end bearing catch is set, locking plate and lock screw with it and lock bearing, when assembling, can make adapter shaft and bearing reach desirable mated condition like a cork, overcome available technology adopting grooved big nut, defective owing to the cooperation that must correspondingly with the aperture position of spring cotter be difficult to reach desirable, again because lock screw thickness is wanted little 2-3CM than grooved big nut thickness, can reduce the assembling height of outer cover of dust, make the recessed wheel hub of the end face outside 2-3CM of outer cover of dust, after adopting such structure, can guarantee the state that well prepares between bearing and the adapter shaft, the outside of the recessed wheel hub of outer cover of dust, can avoid the damage of external force, drop into foreign matter damage bearing and make, cause the inefficacy of equipment; Cover of dust outside snap ring in the wheel hub groove is fixing is provided with seal ring between outer cover of dust and the wheel hub, cover of dust in the inboard directly captive joint of wheel hub, can guarantee under normal mode of operation, foreign matters is dropped in bearing and the adapter shaft, and structure is more simple, and easy to maintenance.
