Detailed description of the invention
Fig. 1 shows a kind of exemplary Work machine 100, i.e. wheel loader.Work machine 100 can also be carried out
The operation relevant to specific industry (such as dig up mine, build, agricultural, transport etc.) at various working environments (such as mining site, building
Building site, farm and road etc.) the middle any other type of machine worked, such as crawler-mounted excavator, wheel grader etc..
Work machine 100 can include that mainframe 30, operator accommodate space such as driver's cabin 35 and work implements 36.?
In one embodiment, work implements 36 can be the scraper bowl being applied to loader.Work machine 100 can include at least one and work
Make facility 36 operation to connect and for controlling the oil cylinder 37 of work implements 36 action.Lower disposed at Work machine 100 has row
Walking apparatus 40, is used for supporting and mobile operation machine 100.In one embodiment, running gear 40 includes wheel 41.
Work machine 100 shown in Fig. 1 can include the differential mechanism that is connected with drive axle so that Work machine is turned and/or
Uneven road surface travels.
Fig. 2 shows the sectional structure of the differential mechanism 10 according to this utility model one embodiment.This differential mechanism includes differential
Device housing, it is arranged in differential carrier body and the planetary gear 13 and the axle shaft gear 14 that are engaged with each other (are united in this utility model
It is referred to as " differential gear ") and the cross axle 15 of assembling planetary gear 13.Differential casing can include being fastened to each other
Left housing 11 and right shell 12.The structure of differential mechanism and working method are to well known to a person skilled in the art, the most too much retouch
State.
Planet gear pad 16 can be provided with, in order to reduce planet between planetary gear 13 and differential casing 11,12
Abrasion between gear 13 and differential casing.As shown in Figures 2 and 3, in order to coordinate in differential casing and bevel gear form
Between planetary gear 13, planet gear pad 16 is in part spherical shell shape, i.e. first table contacted with planetary gear 13 of pad 16
Face 4 is in concave spherical surface shape, and the second surface 5 contacted with differential casing of pad 16 is in convex spherical shape.Planet gear pad 16
The heart can include the hole 3 passed for cross axle 15 wherein, it is, planet gear pad 16 is sleeved on as planetary gear 13
On cross axle 15.
When differential mechanism 10 works, planetary gear 13 can rotate around the axis of cross axle 15, and differential casing is static
Motionless.Owing to planetary case hardness is bigger than the case hardness of differential casing, in order to reduce abrasion, planetary gear pad
Sheet 16 can maintain static relative to differential casing, i.e. stops pad 16 sliding around the axis of cross axle 15 relative to differential casing
Turn；Meanwhile, can reduce as far as possible when planetary gear 13 rotates with contact friction between pad 16.
Trackslip to be reliably prevented pad 16, according to this utility model, the second surface 5 of pad 16 is provided with convex
Playing 2, projection 2 is trackslipped with prevention pad 16 in being configured to be embedded in the respective slot (not shown) being located in differential casing.
The quantity of protruding 2 is unrestricted, can be one or more.Even if only arranging a projection 2, owing to protruding 2 at pad 16
Center (because centrally disposed porose 3), so also can utilize protruding 2 to prevent pad 16 around cross axle with coordinating of respective slot
The axis of 15 trackslips.Certainly, in order to improve anti-rotation effect, pad 16 can be provided with multiple protruding 2.Advantageously, the plurality of protruding 2
At least one pair of projection symmetrically arranged about pad 16 can be included, the most just arrange
A pair such symmetrical protruding.Protruding 2 dash forward towards differential casing in from the second surface 5 of pad 16 in the illustrated embodiment
The form of the square boss gone out, but the shape/configuration of protruding 2 is not limited to this, as long as it can corresponding recessed with differential casing
Slot fit becomes can effectively and reliably prevent pad from trackslipping.The position that arranges of protruding 2 is also not particularly limited, if position
Upper in the second surface 5 (owing to there is the hole 3 being positioned at center, second surface 5 is an annular surface) of pad 16.Favorably
Ground, protruding 2 can be as shown in Figure 3 near the radial outside edge of second surface 5, at the stress that this position projection 2 is born
Relatively small.
On the other hand, friction is contacted, according to this practicality newly in order to reduce between pad 16 and the planetary gear 13 rotated
Type, pad 16 is provided with multiple storage oil pit 1 on its first surface 4 contacted with planetary gear.Arrange storage oil pit to increase and stay
There is the lubricants capacity between pad 16 and planetary gear 13, thus reduce friction.In the illustrated embodiment, the plurality of storage
Oil pit 1 is the circular pit being distributed on the first surface 4 of pad 16.But, store shape/configuration and the distributing position of oil pit 1
It is not limited to this, as long as but lubricating oil can be accumulated wherein and reduce and rub.It addition, store the size of oil pit 1 the most not by spy
Not limiting, typically, the circular oil pit that stores can such as have the diameter of 3mm and the degree of depth of 1mm.
It is not limited to above-mentioned planet gear pad 16 according to differential gear pad of the present utility model.As it is shown in figure 1,
Axle shaft gear pad 17 also can be set between axle shaft gear 14 and clutch housing 11,12.Axle shaft gear pad 17 Ye center
Offer the porose axle portion for axle shaft gear to pass, thus axle shaft gear pad 17 is sleeved in the axle portion of axle shaft gear.With
Unlike planet gear pad 16, axle shaft gear pad 17 in tabular, i.e. its first surface contacted with axle shaft gear and
The second surface contacted with differential casing is plane.In addition, other configuration of axle shaft gear pad 17 (is such as arranged on
Projection on second surface and the storage oil pit arranged on the first surface) can be identical with planet gear pad 16, the most also can subtract
Friction between minor semiaxis gear and differential casing and abrasion.
Industrial applicibility
Can be used especially in the differential mechanism 10 of Work machine 100 according to differential gear pad 16,17 of the present utility model
To prevent from occurring between differential gear 13,14 and differential casing 11,12 inordinate wear.
Specifically, when Work machine is turned and/or travels on uneven road surface, differential mechanism can work to play differential
Effect.Now, differential gear (planetary gear 13 and/or axle shaft gear 14) can be around respective axis relative to differential casing
Rotate.Existence due to differential gear pad (planet gear pad 16 and/or axle shaft gear pad 17), on the one hand, pad
First surface on storage oil pit can accumulate lubricating oil, thus reduce the friction between pad and differential gear；On the other hand,
The projection arranged on the second surface of pad can match with the respective slot in differential casing and be reliably prevented pad and slide
Turn.Therefore, utilize simple structure to efficiently reduce between pad and differential gear and pad and differential casing it
Between abrasion, and and then ensure differential gear the most normally engage, and guarantee drive axle the most normally to work and not
Lost efficacy.
Various Work machine (such as loader, excavator etc.) is can be applicable to according to differential gear pad of the present utility model
Differential mechanism in, but be not limited to this, it is clear that it can be used in any various differential mechanisms needing to arrange anti-wear pad.
For a person skilled in the art, in the case of without departing from scope of the present utility model or spirit, can be right
Various modification can be adapted and modification for foregoing disclosed embodiment.According to disclosed in this specification to practice of the present utility model,
Other embodiments of the present utility model is apparent to those skilled in the art.This specification and disclosed in show
Example should be considered to be only exemplary, and true scope of the present utility model is specified by claims and equivalent thereof.
