Abstract
The utility model discloses a protection floating oil seal's walking motor speed reducer structure, the outside at part one waist is located to the floating oil seal, and the floating oil seal outside is equipped with the part two with part one assembly, and part one is located in the part three with the junction of part two, its characterized in that, the bottom of the extension structure of part one is equipped with protruding structure one, and part two is equipped with protruding structure one matched with the junction of part three sunken, and the outer fringe of part two is equipped with protruding structure two, and the inner wall of part three is equipped with the seal groove with protruding structure two phase fit. The utility model discloses with the motor in addition with the speed reducer part through the structure that forms recess cooperation relation after the assembly, guarantee the operational environment of floating oil seal, improve the life of motor speed reducer product, guarantee when the abominable operating mode of adaptation that can be better that floating oil seal is in comparatively clean and safe's work environment.
Description
Technical Field
The utility model relates to a to the structure of protection such as dustproof of walking motor reducer floating oil seal belongs to walking motor reducer's spare part structure technical field.
Background
The floating oil seal is an important component part in a hydraulic motor and a speed reducer, and mainly has the main function of sealing gear oil in the speed reducer when the speed reducer of a walking motor works or stops, and the floating oil seal is divided into steel surface sealing and elastic sealing of a sealing ring, so that the gear oil leakage of the speed reducer can be caused by the damage phenomenon when the floating oil seal is acted by a foreign object.
At present, most of the structures of the walking motor speed reducer are not provided with a protection structure or only adopt a plastic dust ring. The plastic dust ring is easy to wear and deform in a working state, and cannot effectively play a role in protection.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the floating oil seal protection structure is simple in structure, easy to produce and process, high in stability and low in cost, the condition that the motor speed reducer breaks leaked gear oil under the condition of coping with complex working conditions is reduced, and the service life of the floating oil seal is prolonged.
In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a protection floating oil seal's walking motor speed reducer structure, the outside of part one waist is located to floating oil seal, and the outer fringe on the upper portion of part one is equipped with extension structure, forms the recess between the waist of this extension structure and part one, and in floating oil seal's upper portion was equipped with this recess, the outside of lower part was equipped with the part two with part one assembly, and the extension structure of part one is located in part three with the junction of part two, its characterized in that, the extension structure's of part one bottom is equipped with protruding structure one, and part two is equipped with protruding structure one matched with sunkenly with the junction of part three, and the outer fringe of part two is equipped with protruding structure two, and the inner wall of part three is equipped with the seal groove with protruding structure two matched with.
Preferably, the first projection structure is a cylinder.
The structure can be adopted at the position of the walking motor speed reducer where the floating oil seal is required to be installed. The utility model discloses need not adopt extra protection part, simple structure, workable, stable performance, it is with low costs, the safeguard function is extremely strong and very reliable, saves part reduce cost, and it adds the motor and forms the structure of recess cooperation relation with the speed reducer part through the assembly back in addition, guarantees the operational environment of floating oil seal, improves the life of motor speed reducer product, guarantees when the abominable operating mode of adaptation that can be better that floating oil seal is in comparatively clean and safe's work bad border.
Drawings
Fig. 1 is a perspective view of the structure of the walking motor reducer provided by the present invention.
Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
Examples
As shown in fig. 1, for the utility model provides a pair of walking motor speed reducer structure of protection floating oil seal, floating oil seal 8 locates the outside of part one 1 waist, the outer fringe on the upper portion of part one 1 is equipped with the extending structure, form the recess between the waist of this extending structure and part one 1, in this recess was located on floating oil seal 8's upper portion, the outside of lower part was equipped with part two 7 with part one 1 assembly, part three 3 is located in part one 1's extending structure and part two 7's junction, part one 1's extending structure's bottom is equipped with the protruding structure one 2 of cylinder shape, part two 7 is equipped with protruding structure one 2 matched with sunken 4 with protruding structure one 3's junction, part two 7's outer fringe is equipped with protruding structure two 6, part three 3's inner wall is equipped with the seal groove 5 with protruding structure two 6 matched with.
Wherein, part one 1 is the motor assembly part, part three 3 is speed reducer assembly part 3, part two 6 is speed reducer part 6, and three parts mutually support with recess/arch, form labyrinth structure protection floating oil seal 8.
The utility model discloses simple structure, processing is convenient, the effectual protective part that has saved practices thrift the cost, rotates the during operation at the motor, and hardly gets into contact floating oil seal 8 during foreign object, guarantees floating oil seal 8's normal operational environment, prolongs its life.
