ZHANG Jiaqiao;ZHANG Shouyang;NI Hongjun;School of Mechanical Engineering,Nantong University;  
In order to realize multistage transmission of common lathe and reduce the generation of heat during transmission, a mechanism design scheme for the main motion drive system of a general lathe was proposed. The speed number and speed series were calculated according to the machining requirements of the lathe, firstly. Then, the transmission system mechanism was designed according to the variable speed method. The parameters of key parts such as drive shaft diameter, motor power and gear number were determined, lastly. The whole motion system adopted separated structure, realizing high speed and low speed regulation respectively, with higher efficiency and less heat. The designed mechanism was analyzed by finite element Simulation software Solid works Simulation, and the results showed that the strength, stiffness and other requirements of the design meet the design requirements, and the adjustment of grade 12 speed can be achieved smoothly.
