机床主传动设计[毕业论文+CAD图纸]

摘 要

机床是机械加工的重要设备，在机械制造中占有重要的地位。在一般的机器制造中，机床所担负的加工工作量占总制造工作量的40%－60%，机床在国民经济现代化的建设中起着重大作用。本次设计的题目是机床主传动设计。设计内容包括：确定有关尺寸参数、运动参数及动力参数；据所求得的有关运动参数及给定的公比，写出结构式，校验转速范围，绘制转速图；确定各变速组传动副的传动比值，定齿轮齿数、带轮直径，校验三联滑移齿轮齿顶是否相碰，校验各级转速的转速误差；绘制传动系统图。

关键词:传动比；结构式；传动系统图

ABSTRACT

Lathe 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.

Keywords: transmission ratio; structured; drive system diagram.
