And the trans mission in neutral gear with reverse gear. Transmission also need power output function. Gearbox because of the low-grade work ata larger role, In general, the low-grade gearbox layout are close to the axis after support, Following from low-grade to high-grade order of the layout of stalls gear. This will not only allow axis are large enough for a rigid, but also ensures easy assembly. Gear box overall structure and rigid axle and the shell structure of relations. Generally through the control shaft length control over several stalls to ensure that adequate gear box rigid. This paper describes the design of three-axis five block manual tran mission, the transmission principle of work elaborated, Transmission of the gear shaft and doa detailed design, and the intensity ofa school. For some standard parts for the selection. Transmission Trans mission program design. A brief description of the
