Description
Technical field
The utility model belongs to technical field of engineering machinery, specifically, more particularly to a kind of walking of hydraulic crawler excavator
Motor reducer.
Background technology
At present, excavator with running motor reductor mostly by drive gear, sun gear, I and II planetary gear speed reducing mechanism,
The main members such as one baffle, float grease seal, bearing, reducer shell, adjust pad, elastic spring, end cap are constituted；By driving
Double reduction is realized in transmission between moving gear, sun gear, I and II planetary gear, reducer shell and the motor shell of fixation
Purpose, the structure has the advantages that compact conformation, large speed ratio and change in torque scope are big.
But, when running motor reductor is connected with drive shaft by spline, the effect of the planet carrier of floating in external force
Lower axial float so that matched one baffle produces axial float, is zero with end cap axial gap, because one baffle with
End cap has speed discrepancy, and mutually friction generates heat between the two, energy loss, and the chip that friction is produced can be shed in housing,
Damage reductor.Due to reductor shaft to accumulation work difference it is larger, this gap less stable after assembling, it is difficult to control, and processing
Cost is high；Meanwhile, the excavator of some small tonnages, by being limited by space, it is traditional end cap is fixed with bolt mode be difficult
Realize.
The content of the invention
The purpose of this utility model is to overcome drawbacks described above there is provided a kind of hydraulic crawler excavator running motor reductor,
Its compact conformation, the good, reliability that radiates are high, reduce the heat that one baffle is produced with the mutual friction of end cap phase, and avoid
Its phase mutual friction produces iron filings.
Deceleration device is provided with described hydraulic crawler excavator running motor reductor, including housing and end cap, housing, is subtracted
One baffle is provided between speed variator and end cap；Adjust pad is provided between the one baffle and end cap, adjust pad is rubbed
Wiping face is provided with oil duct.
Further, the groove of the end cap uses a word groove structure, and adjust pad coordinates with groove.
Further, it is respectively equipped with the end cap and housing in the half slot of mutual cooperation, two halves circular groove and is provided with steel wire
Back-up ring.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model sets up the adjust pad that high-abrasive material is made between end cap and one baffle, and in adjustment
The rubbing surface of pad sets up oil duct, and adjust pad coordinates in the groove of end cap；
2nd, the utility model is designed in the adjust pad of a variety of different sizes, assembling process, by axle by dimension chain calculating
To gap (shifting amount) control in rational scope, it is ensured that the stability of reductor, while also reducing adding for parts
Work difficulty；
3rd, end cap trench design is a word groove, is conducive to passing through for lubricating oil, is easy to machining control, while reducing tune
The heat produced during whole packing friction；
4th, end cap and housing have additional half slot respectively, carry out axially position by elastic spring after assembling, make structure more
Step up to gather.

As shown in Fig. 2 one baffle 9 is provided between deceleration device and end cap 8, provided with tune between one baffle 9 and end cap 8
Whole pad 10, the rubbing surface of adjust pad 10 is provided with oil duct 11；Mutual cooperation is respectively equipped with the end cap 8 and housing 1
Elastic spring 7 is provided with half slot, two halves circular groove.
As shown in figure 3, the groove 12 of the end cap 8 uses a word groove structure, adjust pad 10 coordinates with groove 12.
The utility model is driving link with drive gear 6 operationally, and housing 1 is driven member, passes through fluid motor-driven
The rotary motion of axle is sent on the drive gear 6 coupled by splined shaft, and primary planet reducing gear 3 is engaged with drive gear 6
Transmission, then rotated by the drive housing 1 that engages with housing 1, so as to drive the driving of crawler driving whell, realize the one of reductor
Level is slowed down；Primary planet reducing gear 3 is installed in planet carrier 4, and sun gear 5 is connected with planet carrier 4 by the engagement of interior external tooth, and one
Level planetary gear speed reducing mechanism 3 engages drive planet carrier 4 with housing 1 and rotated, so that drive sun gear 5 to rotate, two-stage planetary reduction machine
Structure 2 with sun gear 5 by engaging, then is engaged with housing 1, drives the driving of crawler driving whell, realizes two grades of the present utility model
Slow down.
In the course of the work, the moving vertically of one baffle 9, adjust pad 10 has efficiently controlled altering for one baffle 9
Momentum, reduces the frictional dissipation with end cap 8, while a word groove of end cap 8 is conducive to the lubricating oil in oil duct 11 to pass through, drop
Low reductor heat；End cap 8 is with after the two halves circular groove assembling on housing 1, carrying out axially position by elastic spring 7, making this
