        摘要：A new speed-change transmissiondevice-the gears in 2 pairs of Sliding gearsand 3-axis drives was developed by the machine tool industry of our country. Comparedwith others. this new device features lessgears, more transmission ratios, excellentrigidity. simple and compact structure.However,dueto the lack of suitable method calculating the numbers of gears and teeth for thisdevice,its application and popularization wasgreatly influenced. Based on comprehensiveanalysis,this article recommends a practicalmethod calculating the numbers of gears andtheir teeth. Characteristically raising goodgenerality, simple calculation,easy masteringand popularization.It gines a useful referenceto designing units and enterprises.
