The outer shell and the inner gear rings in the speed reduction device in the mobile machinery have an integral structure, so the speed reduction device has a simple structure. Meanwhile, the process for arranging the inner gear rings in the outer shell is saved, so the labor is saved and the production cost is reduced.
Description
Technical field
The utility model relates to retarder, is specifically related to the speed reduction gearing in a kind of walking machine.
Background technology
In the existing construction machinery and equipment, a kind of drive track-type reductor of use mainly is made up of HM Hydraulic Motor, hydraulic control device, retarder and drg.Retarder in this machine contains body skin, inner housing and two-stage planetary wheeling mechanism.All contain sun gear, planetary wheel, planetary gear carrier and internally toothed annulus in the two-stage planetary wheeling mechanism.Internally toothed annulus in each planetary wheeling mechanism all is fixed on the inwall of body skin of retarder.Because body skin and internally toothed annulus are independent part, need be assembled together at last, therefore manufacturing and the assembling to part all has higher requirement, and this both had been unfavorable for the reduction of productive costs, made its structure become complicated simultaneously again.
The utility model content
The purpose of the utility model is to overcome the defective that exists in the prior art, and the speed reduction gearing in a kind of walking machine is provided, and it is not only simple in structure, and productive costs is low.
For realizing above-mentioned purpose; The technical scheme of the utility model is the speed reduction gearing in a kind of walking machine of design, and said speed reduction gearing includes HM Hydraulic Motor, hydraulic control device, retarder and drg, and described retarder contains body skin, inner housing and two-stage planetary wheeling mechanism; All contain sun gear, planetary wheel, planetary gear carrier and internally toothed annulus in the described two-stage planetary wheeling mechanism; Described internally toothed annulus is arranged in the body skin of retarder, on the outer face of said body skin, is provided with end cap, it is characterized in that; The body skin and the internally toothed annulus of said speed reduction gearing are processed integral structure, on said body skin, be provided with circular groove.
The advantage and the beneficial effect of the utility model are: because body skin and internally toothed annulus in the speed reduction gearing in this walking machine are integral structure, therefore simple in structure.Be installed in the operation in the body skin owing to saved internally toothed annulus simultaneously, therefore having saved manpower has reduced productive costs.

Fig. 1 is the speed reduction gearing structural representation in the utility model walking machine.
Among the figure: 1, body skin; 2, inner housing; 3, drg; 4, motor shell; 5, output shaft; 6, hub splines; 7, input shaft; 8, secondary internally toothed annulus; 9, secondary planetary gear; 10, one-level internally toothed annulus; 11, primary planet pinion; 12, primary planet pinion frame; 13, end cap; 14, one-level sun gear; 15, secondary sun gear; 16, secondary planetary gear frame; 17, sprocket wheel.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.
As shown in Figure 1, the utility model is the speed reduction gearing in a kind of walking machine, and this speed reduction gearing includes HM Hydraulic Motor, hydraulic control device, retarder and drg 3.Speed reduction gearing contains body skin 1, inner housing 2, one-level planetary wheeling mechanism, secondary road wheel mechanism and input shaft 7.The body skin 1 of retarder passes through bearing installation on the inner housing 2 of retarder.HM Hydraulic Motor and hydraulic control device are installed in the motor shell 4, and motor shell 4 is arranged on the end face of inner housing 2.Hydraulic motor output shaft 5 is connected through hub splines 6 with input shaft of speed reducer 7, and hub splines 6 is positioned at inner housing 2.The one-level planetary wheeling mechanism contains one-level internally toothed annulus 10, primary planet pinion 11, primary planet pinion frame 12 and one-level sun gear 14, and the secondary planet wheel mechanism contains secondary internally toothed annulus 8, secondary planetary gear 9, secondary planetary gear frame 16 and secondary sun gear 15.One-level sun gear 14 is fixedly mounted on the input shaft 7, and secondary sun gear 15 is sleeved on the input shaft 7.Three primary planet pinions 11 are arranged on the primary planet pinion frame 12 through rotating shaft and bearing; The spline housing that primary planet pinion frame 12 central authorities are provided with is sleeved on the castellated shaft that secondary sun gear 15 1 ends are provided with, three primary planet pinions 11 all with one-level internally toothed annulus 10 and 14 engagements of one-level sun gear.Three secondary planetary gears 9 through rotating shaft not 11 bearings be arranged on the secondary planetary gear frame 16, three secondary planetary gears 9 all with secondary internally toothed annulus 8 and secondary sun gear 15 engagements.Secondary planetary gear frame 16 is fixedly installed on the inner housing 2, and it also can process an integral structure with inner housing 2.The inner housing 2 of speed reduction gearing is arranged on through bolt on the body of construction machinery and equipment, and sprocket wheel 17 is fixed on the body skin 1 of speed reduction gearing.One-level internally toothed annulus 10 and secondary internally toothed annulus 8 are positioned at the body skin 1 of retarder, and the outer face of body skin 1 is provided with end cap 13, and the body skin 1 of retarder is integral structure with one-level internally toothed annulus 10 with secondary internally toothed annulus 8, on said body skin, is provided with circular groove 18.Because the utility model is made for an integral structure with the body skin 1 of prior art with one-level internally toothed annulus 10 and secondary internally toothed annulus 8, and is therefore simple in structure.Because of having saved one-level internally toothed annulus 10 and secondary internally toothed annulus 8 are installed in the operation in the body skin 1 simultaneously, therefore having saved manpower has reduced productive costs.Hydraulic motor output shaft 5 drives input shaft 7 through hub splines 6 and makes 14 rotations of one-level sun gear during work; Sun gear 14 drives the rolling in one-level internally toothed annulus 10 that primary planet pinion 11 rotates the rotation formation of level planetary wheel 11; Thereby make the spline housing on grade planetary gear carrier 12 drive secondary sun gear 15 rotations; Secondary sun gear 15 drives secondary planetary gear 9 again and rotates; The rolling in secondary internally toothed annulus 8 that the rotation of secondary planetary gear 9 forms is fixedly installed on because of secondary planetary gear frame 16 on the body of construction machinery and equipment, finally makes body skin 1 drive sprocket 17 of retarder drive the walking machine walking.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
