Abstract

According to the processing principle of large-scale CNC gear hobbing machine, a high-precision on-machine measurement method for large gear pitch deviation using relative method and absolute method simultaneously is proposed. The mechanical body of high-precision on-machine measuring instrument with two-stage positioning system are designed to improve the positional accuracy of on-machine measurement. The system structure with upper and lower computers is proposed, which uses the high speed IO port of NC and Ethernet network for communication, so as to make full use of the function of NC system of gear hobbing machine. A large number of repeated experiments show that the range of 10 measurements of the pitch deviation and the cumulative deviation of the pitch in the developed machine are within 1/10 of the tolerance of the 3-grade precision worm specified in the national standard GB10089-88.
