铣削组合机床及其传动装置设计

摘要

组合铣床是根据具体情况的需要,对机床进行合理的设计,使其满足加工要求.在现代机械加工中,组合机床是以系列化、标准化的通用部件为基础，配以少量的专用部件组成的一种高生产率机床。它具有自动化程度较高，加工质量稳定，工序高度集中等特点，因此，组合机床在大批、大量生产中得到广泛应用。目前，组合机床的研制正向高效、高精度、高自动化和柔性化方向发展。

本次设计是完成对铣削组合机床及其传动装置的设计,使其满足对减荷阀体的前后两端面的切削加工.在这一设计过程中,考虑加工时切削参数,合理的选择电动机的功率,并完成对变速箱里的各级齿轮之间的传动配合的设计和转动轴的设计,充分的考虑到传动时所产生的一系列传动要求,例如:传动比,传动扭矩,传动功率等。

ABSTRACT

combination milling machine is in accordance with the specific circumstances of the needs of the machine for a reasonable design, to enable it to meet the processing requirements. In modern processing machinery, machine tools portfolio is serialized and Standardization of components for the common basis, and with a small number of dedicated components consisting of a high productivity machine. It has a fairly high degree of automation, processing, stable quality, highly centralized processes, etc. Thus, the combination of a large number of machine tools, mass production to be widely applied. Currently, the portfolio machine being developed efficient, high-precision, high automation and flexible direction. This design is completed right combination milling machine and its transmission device design, make it responsive to the valve body by the Security Council ends before and after the cutting.

In this design process, Cutting consider when processing parameters, a reasonable choice of motor power, and the completion of the gearbox Lane at all levels between the drive gear with the rotation axis design and the design, Full consideration of the drive when the drive a series of requirements, such as : transmission ratio, transmission torque, transmission power, etc..
