摘 要 本论文所研究的题目是JWB100滚珠丝杠升降机结构设计。主要是对蜗轮蜗杆、蜗轮丝杠的传动部分进行设计，以丝杠、蜗杆、蜗轮为主要的研究对象，对其工作受力性，材料的强度、刚度、韧性和散热性等进行了分析，并以升降机装置的使用特点及用途出发，确定了以蜗轮蜗杆、蜗轮丝杠两种传动装置为主要传动的设计方案，制定了蜗轮、蜗杆、丝杠之间的结构设计。 完成结构设计后，用画图辅助工具Auto CAD绘制了3张A0图纸，清楚地表达了JWB100滚珠丝杠升降机的结构特点和使用性能。 设计的蜗轮丝杆升降机可以单台使用，组合能按一定程序准确地控制调整提升或推进的高度，可以用电动机或其他动力直接带动，也可以手动。它有不同的结构形式和装配形式该装置可以自锁广泛应用于机械、冶金、建筑、水利设备等行业具有结构紧凑、体积小、重量轻、动力源广泛、无噪音、安装方便、使用灵活、功能多、配套形式多、可靠性高、使用寿命长等许多优点。Abstract The paper studies on the topic of JWB100Ball screw elevator design. Mainly on the worm gear, worm gear screw transmission parts of the design, with the lead screw, worm, worm gear as the main research object, its work force, material strength, stiffness, toughness and thermal performance were analyzed, and the lift device characteristics and use, to determine the worm gear, worm screw two transmission devices as the main transmission design, developed a worm gear, worm, screw between the structural design. To complete the structure design, drawing auxiliary tool for drawing Auto CAD 3 A0 drawings, clear expression of the JWB100Ball screw lift structure characteristics and performance. Design of the worm screw lift that can be used in single machine, also can be used in combination. According to certain procedures to accurately control the restructuring to enhance or promote height, can be used to directly drive the motor or other power, and can also manually. It has different forms of structure and form of the assembly, the device can lock. Widely used in machinery, metallurgy, construction, water conservancy facilities and other industries, has the advantages of compact structure, small volume, light weight, wide range of power, no noise, convenient installation, flexible use, multiple functions, supporting form, high reliability, long life and many other advantages. Keywords: Elevator；ScrewWorm；Crane 摘 要 I Abstract II 第1章 引言 1 1.1蜗轮丝杆升降机设计概论 1 1.1.1蜗轮丝杆升降机设计概论 1 1.1.2蜗轮丝杆升降机型号、规格及表示方法 1 1.2国内、外现状及发展趋势 1 1.2.1国内现状及发展趋势 1 1.2.2国外现状及发展趋势 3 1.3 本文研究的主要内容
