【正文】 , using general principle of the 3K(Ⅰ ) pla reduction gear, designing a new 3K(Ⅰ ) pla reduction gear which is suitable to the walks anization, and joining it and the oil motor directly, simplified the walksanization’s transmission. The innovation spot of this design: increase a pair of speedup gear in the 3K(Ⅰ ) pla reduction gear, so it can enhance the rotational speed of the stalk and reduce the brake torque, causes to use a smaller volume brake realizing effectively to apply the brake. In Structure design, the brake and the oil motor parallel are arranged in the reduction gear’s end surface, fully uses the space. In the design, I carried on optimizing the teeth of 3K(Ⅰ ) pla reduction gear and used highly dislodges, and has made the corresponding examination, in the needed velocity ratio, made the volume of the 3K(Ⅰ ) pla reduction gear is the smallest.
