Abstract
A trolley sealing device use for a caterpillar tractor comprises pin bolts, a balance arm, a floating seal seat, sealing rings, a taper bearing, a trolley shaft, floating seal rings and a thrust wheel. The trolley shaft is connected with the balance arm in a linkage mode, the floating seal seat is sleeved on the trolley shaft, one side of the floating seal seat is in contact with a shaft shoulder of the trolley shaft, and the other side of the floating seal seat is in contact with the taper bearing so as to fix the position of the thrust wheel. A left side floating seal ring is mounted on the floating seal seat through a left side seal ring, a right side floating seal ring is mounted on the thrust wheel through a right side seal ring, the taper bearing is sleeved on the trolley shaft, one side of the taper bearing is in contact with the floating seal seat, and the other side of the taper bearing is in contact with a blocking shoulder of a thrust wheel upper hole. The left side floating seal ring and the right side floating seal ring are in mutual contact, the left side seal ring is clamped between the left side floating seal ring and the floating seal seat, and the right side floating seal ring is clamped between the right side floating seal ring and the thrust wheel. The trolley sealing device use for the caterpillar tractor is simple in structure and has double sealing functions, when quite many sundries are accumulated in a labyrinth, foreign matter rotates along with the rotation of the thrust wheel to a place under a shaft, and is discharged along an opening under the floating seal seat, and therefore the trolley sealing device has a self-cleaning function.
Description
Technical field
The utility model belongs to the trac. field, relates to a kind of crawler-tread tractor sealed-in unit bogie
.
Background technology
At present, the sealing of the crawler-tread tractor chassis of domestic production mostly adopts float grease seal, and seal ring is set in the float grease seal left and right sides and adjusts pad, and the float grease seal outside is used labyrinth seal housing and seal cover cap to form whole sealing arrangement.This float grease seal complicated structure, install also cumbersomely, just is difficult to remove if there is foreign matter to be clipped in the labyrinth of seal casinghousing, thereby affected service life of sealing arrangement.Develop recently a kind of double seal effect that has, the chassis hermetically-sealed construction with self-cleaning property, just can address the above problem.
The utility model content
The purpose of this utility model is to provide a kind of relatively simple for structure, easy installation and reliable, crawler-tread tractor sealed-in unit bogie with double seal effect and self-cleaning function.
The technical solution of the utility model is: the crawler-tread tractor sealed-in unit bogie comprises: pin, equilibrium arm, floating sealing base, seal ring, cone bearing, chassis axle, floating sealing ring, caterpillar wheel.The chassis axle connects by pin and equilibrium arm, and floating sealing base is enclosed within on the chassis axle, and a side contacts with the shaft shoulder of chassis axle, and opposite side contacts with cone bearing, forms the position of caterpillar wheel is fixed; The left side floating sealing ring is arranged on floating sealing base by the left side seal ring, and the right side floating sealing ring is arranged on caterpillar wheel by the right side seal ring, and cone bearing is enclosed within on the chassis axle, and a side contacts with floating sealing base, and opposite side contacts with the shoulder block in hole on caterpillar wheel.
The floating sealing ring of the left and right sides contacts with each other.
The left side seal ring is clipped between the floating seal in left side and floating sealing base, and the right side seal ring is clipped between the floating seal in right side and caterpillar wheel.
The utility model can reach following beneficial effect:
With conventional structure, compare, simple in structure, there is the double seal function, when earth dust etc., when the labyrinth inner accumulated is more, along with the rotation of caterpillar wheel, foreign matter can forward the below of axle to and discharge along the opening of floating sealing base below, has self-cleaning property.
The accompanying drawing explanation
Fig. 1 is the utility model crawler-tread tractor sealed-in unit bogie structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.As shown in Figure 1: the crawler-tread tractor sealed-in unit bogie comprises: pin 1, equilibrium arm 2, floating sealing base 3, seal ring 4, cone bearing 5, chassis axle 6, floating sealing ring 7, caterpillar wheel 8 form.Chassis axle 6 connects by pin 1 and equilibrium arm 2, and floating sealing base 3 is enclosed within on chassis axle 6, and a side contacts with the shaft shoulder of equilibrium arm 2, and opposite side contacts with cone bearing 5, forms the position of caterpillar wheel 8 is fixed; Left side floating sealing ring 7 is arranged on floating sealing base 3 by left side seal ring 4, and right side floating sealing ring 7 is arranged on caterpillar wheel 8 by seal ring 4, and cone bearing 5 is enclosed within on chassis axle 6, and a side contacts with floating sealing base 3, and opposite side contacts with the hole shoulder block on caterpillar wheel 8.The floating sealing ring 7 of the left and right sides contacts with each other.Left side seal ring 4 is clipped between the floating seal 7 in left side and floating sealing base 3, and right side seal ring 4 is clipped between the floating seal 7 in right side and caterpillar wheel 8.
Floating sealing ring 7 outsides and caterpillar wheel 8 form labyrinth, are the first resealing, and less dust enters the float grease seal formed by floating sealing base 3, seal ring 4, floating sealing ring 7 behind labyrinth and blocks, and has realized double seal; And the foreign matter in sealing arrangement is when more, along with caterpillar wheel 8 rotates, foreign matter can turn to chassis axle 6 belows, and discharges along with the lower opening of floating sealing base 3, realizes self-cleaning function, has extended the service life of sealing arrangement.
