The helical transmission uses a pair of screw and nut to meet the requirements of transmission, which are mainly used to change rotary movements into linear movements, at same time, transmitting motion and force. According to the method to calculate efficiency and taking the characteristics and forms of the transmission, the authors designed a simple and convenient measuring system, which can make the helical burr under fixed load move reciprocally and continuously, under the control of control-box, collect data through sensor and draw an efficiency picture automatically. The system not only can measure the helical transmission efficiency of rectangular screw thread,zigzag screw thread and trapeziform screw thread,but also is convenient to change the helical apparatus. The experiment shows that it is reasonable and the data given by the system is accurate.
