The object of the present invention is achieved like this: a kind of multi-input countershaft-planetary reducer, comprise casing, planetary gear train, bearing and output spline housing, and it is characterized in that:
A) input end of speed reducer is provided with three input gear shafts at least, and the input end of input gear shaft is provided with internal spline;
B) the input gear shaft is evenly distributed on around the actuation gear, and gear and the actuation gear of input gear shaft mesh, and the actuation gear center is connected with sun wheel shaft in the planetary gear train by spline;
C) planet carrier in the planetary gear train is connected with concentric spline housing by bolt and pin.
In the present invention: the input gear shaft, and is furnished with input end and covers thoroughly on right case by Bearing Installation; Three planet wheels at least evenly are set in the planetary gear train, and the sun wheel shaft two ends in the planetary gear train are provided with jacking block, and are furnished with a ball top.
In the present invention: the input end of speed reducer is provided with six input gear shafts; The spline that actuation gear is connected with sun wheel shaft adopts crowned teeth; Spline housing in the planet carrier connects by spline and output spline housing.
In the present invention: actuation gear is provided with concentric measure speed gears, and is furnished with stifle, and stifle is provided with speed measurement device.
In the present invention: described speed measurement device comprises the measure speed gears axle, and measure speed gears axle one end is a distance ring, and the other end is a flange, and is furnished with muff, safety cover and the lid that tests the speed, the gear of measure speed gears axle and measure speed gears engagement.
The invention has the advantages that: owing to adopted a plurality of parallel input gear shafts, drive an actuation gear, adopt the power dividing of multirow star-wheel simultaneously in the planetary gear train, improved the output torque of speed reducer as input end; The jacking block at sun wheel shaft two ends and ball top in the planetary gear train can prevent that the sun wheel shaft of floating from producing the front and back displacement at work; The spline that actuation gear is connected with sun wheel shaft adopts crowned teeth, can the angle of deviation be compensated; In the speed reducer of equal transmission speed ratio and output torque, the volume that has reduced complete machine is less lighter with weight, and low cost of manufacture, and is with short production cycle; Owing to be provided with speed measurement device in the speed reducer, can accurately calculate the actual displacement distance that is decelerated machine travel (or lifting) thing after transforming according to the rotating speed that obtains, monitor being pulled thing residing physical location in the process of traction (or lifting).
