Protect expense.
Content of the invention
The utility model main purpose is to provide the large-duty loader drive axle supplementary reduction of a kind of life-span length, dependable performance
Gear assembly.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals: a kind of large-scale loading
Machine drive axle supplementary reduction gear assembly, including constitute the gear-driven ring gear of planet row, planetary gear and sun gear, it is special
Levy and be: on described ring gear outer circumference surface, be evenly distributed with several external tooths；The lower half of ring gear periphery is provided with some
Individual oil-way, these oil-ways are symmetrical set along ring gear center vertical plane.This structure, fluid is from ring gear
Portion contacts, and increase contacts effect with ring gear, and especially oil-way reduces the thickness of thermal conduction portions, enhancing heat radiation effect
Really；Avoid internal temperature overheated and cause the mesh tooth face of driving member to damage so that the length in service life of gear assembly and complete machine,
Stable and reliable for performance.
As preferably, the bottom land of described oil-way connects with the outer root portion of groove both sides；The width of oil-way is
2-4 times of external tooth space width.This structure, fluid can obtain more preferably heat radiation and lubricant effect further.
As preferably, described sun gear is column, and left end is outer cylinder gear, and right-hand member has in endoporus and this endoporus
Internal spline is set.Left end engages with planetary gear, and right-hand member is in transmission connection with outside composition by internal spline.
As preferably, described planetary gear is radially arranged two oilholes；The two through planetary gear sides of oilhole
Wall, and it is in different axial locations.Can obtain preferable lubricant effect, lubricating fluid is more evenly distributed rationally, and regions of lubrication is more
Comprehensively.
As preferably, described planetary gear both ends of the surface are respectively arranged with four circular arc oil-ways；With four circular arcs on end face
Oil-way is grouped two-by-two, and two components are placed in both sides, planetary gear end face center；It with the bottom land of two circular arc oil-ways of group is
Arc is simultaneously on same arc surface.This structure, had both been easy to lubricating fluid and had entered, be easy to again processing；Especially symmetrical configuration, no
Affect planetary harmony.
Therefore, the utility model is by the oil-way of the lower half setting in ring gear periphery, at planetary gear two ends
Circular arc oil-way that face is arranged and the symmetrical arcuate structure of circular arc oil-way, make the utility model have life-span length,
The beneficial effect of dependable performance.

Detailed description of the invention
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment: a kind of large-duty loader drive axle supplementary reduction gear assembly of the utility model, such as accompanying drawing the 1st, accompanying drawing the 2nd,
Shown in accompanying drawing 3, it includes constituting the gear-driven ring gear of planet row the 1st, planetary gear 2 and sun gear 3, described ring gear 1
Inner peripheral wall there is internal tooth 5, outer circumference surface is evenly distributed with several external tooths 4；If the lower half of ring gear 1 periphery is provided with
Dry oil-way 6, these oil-ways 6 are symmetrical set along ring gear 1 center vertical plane.
As shown in Figure 3, the bottom land of oil-way 6 connects with external tooth 4 root of groove both sides；The width of oil-way 6 is
2-4 times of external tooth 4 space width.
As shown in Figure 7, sun gear 3 is column, and left end is outer cylinder gear 9, and right-hand member has in endoporus and this endoporus
Internal spline 10 is set.
As shown in Figure 4, planetary gear 2 is radially arranged two oilholes 7；The two through planetary gear sides of oilhole 7
Wall, and be in different axial locations, i.e. planetary axially in setting of staggering.
As shown in accompanying drawing the 5th, accompanying drawing 6, planetary gear 2 both ends of the surface are respectively arranged with four circular arc oil-ways 8；With four on end face
