Abstract
The utility model discloses a waterproof mine car wheelset which comprises a pair of hubs and a connecting shaft for connecting the hubs, wherein bearings and neck bushes are arranged at two ends of the connecting shaft and are matched and connected with the hubs; oil holes are formed in the hubs and are corresponding to the neck bushes; a bearing catch, a screw anti-rotation locking plate and a locking-screw rigid bearing are arranged at the end part of the connecting shaft; 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 through a snap ring arranged in a hub groove; and oil seal is arranged behind the bearing on the inner side of the hub. The top surface of each outer dustproof cover is sunk in the outer side of each hub for 2-3cm, so that the damage of external force can be avoided, and foreign matters cannot fall into the outer dustproof cover to cause equipment to lose efficacy. The waterproof mine car wheelset has a simple structure and is convenient to maintain. Each outer dustproof cover is fixed through the snap ring arranged in the hub groove, and the sealing ring is arranged between each outer dustproof cover and each hub, and each oil seal structure is arranged at the rear part of the inner side of each hub, so that water and the foreign matters are more difficult to enter into the bearing, engine oil can be filled to the bearing through the oil seal, the bearing rotation is more flexible and easier, and the service life is longer.
Description
Technical field:
The utility model relates to mine transportation equipment, specifically is that a kind of water proof type 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 at present is right, 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 difficult to fit like a glove when assembling on open slot on the grooved big nut and the spring cotter, causes 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, and is 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 outer cover of dust protrude the side of 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, like " tramcar wheel to " of the patent No. 201020507301.0; Comprise a pair of wheel hub and the adapter shaft that is connected wheel hub, at the two ends of adapter shaft bearing, inner covering and wheel hub be set and be connected that wheel hub is provided with oil hole; Oil hole exports corresponding inner covering, is provided with interior cover of dust in the inboard of wheel hub, and interior cover of dust is fixedly connected on the wheel hub; Bearing catch, locking plate and lock screw fixed type bearing are set in the end of adapter shaft, and cover of dust outside the arranged outside of wheel hub is 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, this tramcar wheel is wanted little 2-3CM to lock screw thickness than grooved big nut thickness, can reduce the assembling height of outer cover of dust; Make the recessed wheel hub of the end face of outer cover of dust outside 2-3CM, adopt such structure after, 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, cause the inefficacy of equipment and make; 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, but for many water in mine and the environment of humidity, the structure of this interior cover of dust; Be difficult to prevent that sealing gets in the bearing, and influence the result of use of equipment.
Summary of the invention:
The purpose of the utility model is a kind of simple in structure, the rotation that guarantees the mine car wheel set bearing effectively flexibly, easily, longer service life, the better water proof type tramcar wheel of reliability is right.
In order to achieve the above object; This water proof type tramcar wheel is provided with bearing, inner covering and wheel hub at the two ends of adapter shaft and is connected comprising a pair of wheel hub and the adapter shaft that is connected wheel hub, and wheel hub is provided with oil hole; Oil hole exports corresponding inner covering; Be provided with interior cover of dust in the inboard of wheel hub, interior cover of dust is fixedly connected on the wheel hub, and bearing catch, screw anti-revolution locking plate and lock screw, fixed type bearing are set in the end of adapter shaft; 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, it is characterized in that: the back at the wheel hub inboard bearing is provided with oil sealing.
After adopting such structure; Bearing catch, locking plate are set in the adapter shaft end and lock screw with it and lock bearing, when assembling, can make adapter shaft and bearing reach desirable mated condition like a cork, 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, the damage of external force can be avoided in the outside of the recessed wheel hub of outer cover of dust; 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, can guarantee that foreign matters is dropped in bearing and the adapter shaft under normal mode of operation, and structure is more simple, and easy to maintenance; The back inboard at wheel hub is provided with oil enveloping structure, makes that like this water and foreign matter more are difficult to get in the bearing, can also be through oil sealing to the bearing machine oil of annotating, make bearing rotate more flexibly, light, longer service life.
