Abstract

Fine-pitch gears with module ranging from 0.05 to 0.5 are widely used in the fields of dial indicators, aeronautic gauges and instruments, timers and watches and so on; but because of their small size and weak rigidity and small aount of inertia, so far there are few methods in practice being able to meet the requirements of their reliable, precise and efficient accuracy measurements, especially in batch production. Based on the gear integrated error measuring technology and the gear single flank rolling tester, a differential type of gear single flank point rolling scan measuring technique and a prototype of the gear differential single flank rolling tester have been developed to explore a new way to solve the problem. By using a special made master gear, the tester can perform not only the measurement of the gear tangential composite deviations but also the measurement of the gear elementary deviations, including profile deviations and pitch deviations, and also integrated deviatons of fine-pitch gears in batch production with high efficiency and accuracy. The conception of "Two spindles be driven in synchronization, and one differential measurement be in closed loop" and the design structure of "spindle on spindle" adopted by the prototype are introduced in the paper. Some practical measurement results in factory and a few discussions are also presented.
