Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: the utility model mainly is made up of input block, output block, box part, Gear Planet Transmission parts etc.Power is by oil hydraulic motor input in addition, through planetary driving device, at last by the output block outputting power.Shown in Figure 1, input connecting sleeve 1 two ends of input block are connected with the sun gear 2 in oil hydraulic motor and the Gear Planet Transmission parts respectively, one duplex planet wheel 3 is connected together by the planet wheel shaft of centre by the first planet wheel 3A and the second planet wheel 3B, the wherein first planet wheel 3A and a fixed gear ring 4 engagement, the second planet wheel 3B simultaneously with described sun gear 2 and output block in output gear 5 engagements.Described planet wheel shaft is installed on the input shaft of described input block by a planet carrier 6 that floats installation; Described output gear 5 meshes with the interior external tooth of output shaft 7, and this output shaft 7 connects crowned teeth 8 by the form of spline, and crowned teeth 8 meshes with output spline housing assembly 9, and with the contact of sphere form, output flange 10 is fixedly mounted on the output spline housing assembly 9.
Power is by tyre oil hydraulic motor input, passes to sun gear 2 through the spline of oil hydraulic motor by input connecting sleeve 1, and the second planet wheel 3B in sun gear 2 and double-planetary gear passes to output gear 5, finishes be expert at deceleration in the star device of power thus; Power after the deceleration passes to output shaft 7 by output gear 5, passes to output flange 10 and outputs power by output shaft spline, rack barrel 8, output spline housing assembly 9 at last.Output flange 10 is for externally connecting, and output flange 10 is fixed on the output spline housing assembly 9, and output spline housing assembly 9 contact with the sphere of 8 of crowned teeths, can guarantee that output flange 10 swings its maximum permission pivot angle 1.5 around axis., satisfied the rotation requirement of concrete mixer rotating cylinder.
The split-type structural that box part described in the utility model adopts, it can guarantee the installation and removal maintenance of planetary part, the polyethylene stifle of input end is effectively isolated the dust of cement mixing drum.
The utility model can transmit input maximum speed: 2500r/min, reduction speed ratio: 132: 1
Realize max. output torque: 48000N.m.
The radiating structure design of casing has guaranteed the constant of transfer case temperature, so speed reducer can satisfy the usage requirement of the rugged environment and the operating mode of concrete mixer well.
