卧式车床主轴箱设计 摘 要 金属切削机床在国民经济现代化建设中起着重大的作用。机床技术水平的高低已成为衡量一个国家工业现代化水平的重要标志之一。机床工业是机械制造业的“装备部”，对国民经济的发展起着重大作用。 本论文设计的主轴箱的变速级数是12级，传动比为1.41，转速从31.5r/min到1440r/min，加工工件的最大直径为400mm，。论文对箱体内结构进行方案设计，并对传动方案、传动路线进行了分析，离合器、带轮、润滑系统、密封装置等进行了设计、计算及校核。 本设计的主要内容包括：1.运动设计：定主轴的转速、结构式、结构和转速图、确定齿轮的齿数、皮带轮的设计计算实际转速和标准速偏差等。动力设计：各传动轴的转速、各轴的直径、齿轮强度验算、主轴刚度的校核、轴承寿命的验算、选择。 HORIZONTAL LATHE SPINDLE BOX DESIGN ABSTRACT Metal-cutting machine tool in the modernization of the national economy plays an important role. The level of machine technology has become the measure of a countrys level of industrial modernization of one of the important symbols. Machine tool industry is the machinery manufacturing industry, the Ministry of Equipment, the development of the national economy played a major role. In this paper, the design of the spindle box is a series of 12 speed, 1.41 gear ratio, speed from 31.5r/min to 1440r/min, the maximum workpiece diameter of 400mm,. Papers箱体内structure of the program design, and program transmission, transmission line analysis, clutch, pulley, lubrication systems, such as a seal design, calculation and checking. The main elements of the design include: 1. Campaign Design: to determine the speed of the spindle to draw up a reasonable-structured, the structure of network and the speed map to determine the number of teeth of gears, pulleys, as well as the design and calculation of the actual speed and standard deviation of the check, such as speed. 2. Dynamic Design: to estimate the speed of the shaft, to estimate the diameter of the axis, select the motor, gear strength check, the check spindle rigidity, bearing life of the check, select the clutch. 3. Structural Design: To determine the spatial arrangement of drive components.
