内容简介：

ABSTRACTABSTRACTLathe is an important machining equipment, machinery and holds an important position. In the general machinery manufacturing, machine processing shouldered by the total manufacturing work accounts for 40-60% of the workload. Machine modernization of the national economy building plays a major role. The design is Ordinary main drive design. Rebuild right design for the main drive to master machine side case design, and machine tools can reasonably determine the main technical parameters; Transmission master machine design and the calculation method; structural design and master the method of calculation, and so on. Design elements include: a parameter to determine the size, movement parameters and dynamic parameters; According to the two sought by the movement parameters and to the transmission ratio, as well structured and testing speed, rendering ageing period; to determine the variable speed drive Group Vice drive ratio gear teeth fixed, pulley diameter, Check triple Top Gear slip whether a collision speed calibration levels of speed error; Drawing drive system diagram.
