The objective of the invention is to realize like this: a kind of multi-input countershaft-planetary reducer; Comprise casing, planetary gear train, bearing and output spline housing; Described casing comprises the left box body of outlet side and the right case of input side; The ring gear of planetary gear train is characterized in that between left box body and right case:
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, gear and the actuation gear engagement of input gear shaft, and the actuation gear center is passed through spline and is connected with sun wheel shaft in the planetary gear train;
C) planet carrier in the planetary gear train is connected with concentric spline housing with pin through bolt, and concentric spline housing passes to export and covers thoroughly by bearings in left box body, and concentric spline housing is concentric with planet carrier;
D) concentric spline housing connects through spline and output spline housing.
In the present invention: the input gear shaft passes through Bearing Installation on right case, and is furnished with input end and passes through lid; 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.
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 after transforming according to the rotating speed that obtains by the actual displacement distance of speed reducer traction (or lifting) thing, monitor being pulled thing residing physical location in the process of traction (or lifting).
