目前侧边传动的旋耕机,其传动路线长而曲折,构造复杂,刀轴两端扭矩相差悬殊,重心偏离机组中心线,因而不利于制造与使用;中央传动的旋耕机具有结构简单,重心居中,刀轴两端扭矩分配均衡等优点。但它的最大问题是中央传动齿轮箱位于耕幅中央,它所占据的横向宽度,刀齿无法耕 At present, the side-driven rotary tiller has long and tortuous driving paths and complex structures. The torques of the two ends of the axles are greatly different from each other and the center of gravity deviates from the centerline of the generating set, which is not conducive to manufacture and use. The central-driven rotary tiller has the advantages of simple structure, Center of gravity, knife shaft torque distribution at both ends and other advantages. But its biggest problem is that the central transmission gear box is located in the middle of the tillage, it occupies the width of the width, the teeth can not cultivate
