Abstract
The invention discloses a walking speed-reducing mechanism convenient for replacement of a floating oil seal and an excavator thereof. The excavator comprises the walking speed-reducing mechanism, and the walking speed-reducing mechanism comprises a hydraulic motor, and a speed reducer which is arranged opposite to the hydraulic motor, wherein the speed reducer comprises a big end cover and a small end cover, and the small end cover can be disposed on the big end cover axially and detachably in a sleeving manner and is in overlap joint with the hydraulic motor. The floating oil seal is arranged in a space formed by the small end cover and the hydraulic motor. When the floating oil seal is damaged and required to be replaced, the whole walking speed-reducing mechanism does not need to be demounted, a hydraulic oil pipe on the motor does not need to be removed, and the floating oil seal can be replaced only by screwing down bolts on the speed reducer side and detaching the small end cover, so that the floating oil seal is more convenient to replace, the pollution of a hydraulic system can be prevented and therefore, the secondary failure can be avoided.
Description
Technical field
The present invention relates to construction machinery and equipment, relate in particular to a kind of traveling retarding mechanism and excavating machine thereof of being convenient to change float grease seal.
Background technology
Traxcavator is to apply extremely general construction machinery and equipment, crawler-type traveling is by fluid motor-driven, further carry out transmission by reductor, in the junction of HM Hydraulic Motor and reductor, float grease seal need to be set seals, after oil sealing breakage, will lose sealing function, easily cause the leakage of hydraulic oil, therefore, when needing timely replacing after oil sealing wearing and tearing
Existing traveling retarding mechanism has structure as shown in Figure 1 conventionally, in this traveling retarding mechanism, reductor end cap 10 is connected with hydraulic pressure digging machine drive wheel, HM Hydraulic Motor cover plate is divided into large end cap 40 and small end cover 30 these two parts, float grease seal 20 is arranged between reductor end cap 10 and small end cover 30, and large end cap 40 and small end cover 30 are bolted, and by bolt, large end cap 40 is fixed on excavating machine mobile roof support plate with small end cover 30.
Above-mentioned traveling retarding mechanism, in the time changing float grease seal, need to, by HM Hydraulic Motor complete removal from traveling retarding mechanism, just can be changed, and easily causes the pollution of hydraulic efficiency pressure system, thereby cause secondary fault in this process.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of traveling retarding mechanism and excavating machine thereof of being convenient to change float grease seal.
In order to achieve the above object, the present invention has adopted following technical scheme:
The invention provides a kind of traveling retarding mechanism of being convenient to change float grease seal, there is such feature, comprising: HM Hydraulic Motor; Reductor, arranges with HM Hydraulic Motor subtend; Wherein, reductor has large end cap and small end cover, and small end cover is removably axially sleeved on large end cap and with HM Hydraulic Motor and overlaps mutually; Float grease seal is arranged in the space of small end cover and HM Hydraulic Motor formation.
Further, in traveling retarding mechanism provided by the invention, can also there is such feature: also comprise the track frame supporting plate being connected with HM Hydraulic Motor.
Further, in traveling retarding mechanism provided by the invention, can also there is such feature: also comprise the drive wheel being connected with small end cover.
Further, in traveling retarding mechanism provided by the invention, can also there is such feature: small end cover is connected by several bolted with large end cap.
Further, in traveling retarding mechanism provided by the invention, can also there is such feature: several bolts are along the axial annular arranged in arrays of large end cap.
In addition, the present invention also provides a kind of excavating machine, comprises the traveling retarding mechanism in above-mentioned any one.
The beneficial effect that the present invention has is on the basis of the above:
Traveling retarding mechanism provided by the invention, in the time that float grease seal occurs that damage needs to change, without whole traveling retarding mechanism is pulled down, also without the hydraulic oil pipe of removing on motor, only the bolt of deceleration pusher side need be backed out and unloaded after small end cover is just replaceable float grease seal, make the replacing of float grease seal convenient, can not cause the pollution of hydraulic efficiency pressure system, thereby avoid causing secondary fault simultaneously.
