PAGE  PAGE 56 龙门铣床的主轴箱、进给系统及工作台的设计 （） 摘要：本文主要是针对龙门铣床的主轴箱、进给系统及工作台的设计。根据特定的设计要求，结合龙门铣床的运动特点，进行一次较为系统设计。本次设计所有进给机构均采用滚珠丝杠进行传动，并由步进电机电机进行驱动。本次设计重点是对于主轴箱、进给系统的机械部分进行设计，包括转速图的拟定、齿轮的设计、轴最小轴直径的设计、轴承的选取、滚珠丝杠的选取等。 关键词：龙门铣床；主轴箱；工作台；进给系统； Milling machine headstock, feed systems and the design of the table Liu Zhendong (Mechanical Engineering School Inner Mongolia University of Science and Technology Baotou 014010 ) Abstract: This article is mainly for milling machine design. Depending on the specific design requirements, combined with the milling machine movement characteristics, to conduct a more systematic design, including the design of the headstock, the feed system design, table design. The design of all ball screw feed mechanism are used for transmission, motor driven by stepper motors. The design focuses on the mechanical part of the milling machine design, including the speed chart in the formulation, gear design, minimum shaft diameter shaft design, the selection of bearings, ball screw selection and so on.
