Description

A kind of sealing structure of crawler tractor thrust wheel
Technical field
This utility model belongs to tractor field, is related to a kind of sealing structure of crawler tractor thrust wheel.
Background technology
At present, in the crawler tractor that China produces, the sealing of its walking mechanism mostly adopts floating sealing and labyrinth Formula sealing is used in combination, and invades for anti-dust, anti-muddy water.Crawler tractor is in wetlands such as mire, marshes or on tunnel, mountain When working under the bad working environments such as ground, muddy water and dust often enter in the sealing structure of train along the gap of labyrinth structure, It is difficult to clear up, cause the sealing surface of floating sealing ring to damage, and then destroy the sealing of train, the normal work of impact train, Product quality is made a big impact.Therefore, a kind of compact conformation of development, versatility are good, can effectively resist under bad working environments Dirt, the sealing structure of muddy water invasion and attack, are all desired for tractor manufacturer and user.
Utility model content
The purpose of this utility model is that offer one kind is simple and compact for structure, generalization degree is high, energy under bad working environments Effectively resist dirt, the sealing structure of the crawler tractor thrust wheel of muddy water invasion and attack.
This utility model is achieved through the following technical solutions above-mentioned purpose:A kind of sealing knot of crawler tractor thrust wheel Structure, including:Thrust wheel, interior sealing shell, bolt, packing ring, anti-muddy water sealing ring, external seal shell, lock washer, locking nut, close Seal III, sealing ring II, long key, floating oil sealing, taper roll bearing, supporting wheel shaft, counter-jib, sealing ring I, adjust pad; Taper roll bearing set is attached on supporting wheel shaft, and pierces in counter-jib;Taper roll bearing passes through interior sealing columella to calmly Position, sealing ring I, adjust pad is put between interior sealing shell, counter-jib, is fixed by bolt, packing ring;Interior sealing shell and outer close Connected by anti-muddy water sealing ring, floating oil sealing between capsule, sealing ring II is arranged between external seal shell and thrust wheel;Zhi Chong Wheel passes through tapered roller bearing internal ring axially position, is arranged on Zhi Chong by long key, sealing ring III, lock washer and locking nut On wheel shaft.
This utility model is using can reach following beneficial effect after technique scheme:Simple and compact for structure, versatility is good, Because anti-muddy water sealing ring is that internal lip is sealed, good seal performance, can effectively resist dirt, muddy water under bad working environments Invasion and attack.
Brief description
Fig. 1 is a kind of structural representation of the sealing structure of this utility model crawler tractor thrust wheel.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described.As shown in figure 1, a kind of crawler tractor thrust wheel Sealing structure, including:Thrust wheel 1, interior sealing shell 2, bolt 3, packing ring 4, anti-muddy water sealing ring 5, external seal shell 6, lock pad Piece 7, locking nut 8, sealing ring III 9, sealing ring II 10, long key 11, floating oil sealing 12, taper roll bearing 13, supporting wheel shaft 14th, counter-jib 15, sealing ring I 16, adjust pad 17.During installation, first taper roll bearing 13 inner ring is assembled to supporting wheel shaft 14 two ends, pierce in counter-jib 15;Assembling taper roll bearing 13 outer ring, by interior sealing shell 2 axially position, assembles sealing ring I 16, adjust pad 17, is fixed finally by bolt 3, packing ring 4, and period of assembly adjusts circular cone rolling by adjust pad 17 The gap of sub- bearing 13;Floating oil sealing 12 is assembled by interior sealing shell 2, external seal shell 6, when assembling external seal shell 6, should first fill Prepare anti-muddy water sealing ring 5, sealing ring II 10;During assembling thrust wheel 1, thrust wheel hub is axially fixed to taper roll bearing 13 inner ring Position, then be arranged on supporting wheel shaft 14 by long key 11, sealing ring III 9, lock washer 7 and locking nut 8.
When the thrust wheel 1 that connected as one with external seal shell 6 is rotated, the moving-coil of floating oil sealing 12 and be assemblied in external seal shell On 6, the inner ring of anti-muddy water sealing ring 5 also together rotates, and is assemblied in the outer ring of anti-muddy water sealing ring 5 and balance on interior sealing shell 2 Arm 15 keeps geo-stationary, and they rely on the internal lip of anti-muddy water sealing ring 5 to be sealed, and structure is simple, using reliability.Sealing Performance is good, can effectively resist the invasion and attack of dirt, muddy water under bad working environments.
