Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of caterpillar wheel.
Background technology
Caterpillar wheel is the one in the caterpillar chassis such as excavating machine, bulldozer in four-wheel one band, and its Main Function is the weight supporting excavating machine, bulldozer, allows crawler belt advance along wheel; Copper sheathing or composite metal cover are equipped with in caterpillar wheel inside in existing creeper undercarriage, copper sheathing as plain bearing use, inner charging-up lubricant oil; Gap is had to store lubricating oil between supporting wheel shaft and copper sheathing; The sealing of caterpillar wheel lubricating oil adopts float grease seal sealing, the floating sealing ring linear velocity≤2m/s of float grease seal in existing national standards, and floating sealing ring linear velocity limits the rotating speed of the caterpillar wheel of existing structure form; The crawler type traveling machine that some speeds of travel of market demand are higher, as crawler type harvest machinery; The creeper undercarriage of the speed of travel >=10km/h all can not adopt the caterpillar wheel of existing structure form (copper sheathing adds float grease seal).
Summary of the invention
The purpose of this utility model is to provide a kind of caterpillar wheel that antifriction-bearing box is housed, and it is durable in use, and the caterpillar wheel that can solve existing structure form is unsuitable for the problem of high-speed operation.
The technical scheme in the invention for solving the technical problem is: described caterpillar wheel, comprise caterpillar wheel body, the inside of described caterpillar wheel body is provided with wheel shaft, described caterpillar wheel body is connected by antifriction-bearing box with between wheel shaft, the two ends of caterpillar wheel body are respectively equipped with the oil seal seat be connected with wheel shaft, oil seal seat and caterpillar wheel body are bolted, muddy water oil sealing is also equipped with between oil seal seat and wheel shaft, described muddy water oil sealing comprises oil sealing outer ring and oil sealing inner ring, described oil sealing outer ring and oil seal seat closely cooperate, described oil sealing inner ring and wheel shaft closely cooperate, four road seal strips are connected with between described oil sealing outer ring and oil sealing inner ring, abut in the outer end of described oil sealing inner ring and have wheel end cap, describedly take turns end cap is fixed on wheel shaft two ends by bearing pin.
O type circle is provided with between described caterpillar wheel body and the upper surface of oil seal seat.
The beneficial effects of the utility model are: muddy water oil enveloping structure novel and practicable of the present utility model is in the higher occasion of rotating speed, coordinate described antifriction-bearing box, make caterpillar wheel of the present utility model at operation process transfer more than scooter 1000r/min, speed can reach 20km/h, well solves the problem that the common caterpillar wheel speed of travel is low; Between described oil sealing outer ring and oil sealing inner ring, be connected with four road seal strips, entering of muddy water can be prevented, well can seal again the lubricating oil of axle interior, good seal performance, durable in use, and then improve the service life of caterpillar wheel.
