Shift is posed of the main parts of the machine parts, all of the transmission parts motion (for example: gear, gear, etc.) must be installed in the transmission of power to exercise and shaft transmission, often used in the connection between the transmission and drive. The shaft generally is long, and the high speed, can withstand torque not inherit the moment. Should make the shaft has enough rigidity and high speed, strength calculation, because of the large safety factor, thus make shaft dimension.Keywords：S
