毕业设计（论文-电动螺旋千斤顶的结构设计.docVIP

PAGE 1摘 要本设计主要是对电动螺旋千斤顶的结构设计，在原有手动螺旋千斤顶的基础上，通过对螺旋千斤顶了解和学习，选择对其进行改进，设计出一套蜗轮蜗杆机构，利用电机带动蜗杆，蜗杆蜗轮传动带动丝杠运转，由丝杠螺母形成的滑动螺旋副运动将重物顶起，既发挥了螺旋副的自锁性的优点又可改善劳动条件。同时提高了市场的竞争能力。本设计根据承受载荷，设计出丝杠传动机构，根据丝杠传动的工作速度与螺杆所承受的扭矩，来设计蜗杆和蜗轮传动机构，得出蜗杆传动扭矩来进行电机的选型，并使用Pro/ENGINEER 5.0和AutoCAD三维建模软件，设计零件并进行装配。用SolidWorks进行仿真制作。并对蜗杆模型通过ANSYS软件进行简单的有限元分析来完成整个设计。关键字：蜗轮蜗杆；有限元分析；丝杠传动；仿真；三维建模AbstractThe design is mainly for the structural design of screw jacks, screw jacks in the original on the jackscrew through understanding and learning, choose to improve it, to design a worm gear mechanism, the use of motor driven worm and worm gear drive screw operation, the heavy top, both played a spiral lock of the advantages of self but also improve peoples deputy of the working conditions. Improve the competitiveness of the market. The design of the load bearing design of the screw drive mechanism according to the operating speed of the screw drive torque of the screw is exposed to the worm and the worm gear is enough design, draw worm drive torque of the motor to the selection and use Autocad Proe 5.0 and three-dimensional modeling software, design and assembly of parts. With solidworks simulation production. And a simple worm model by ANSYS finite element analysis software to complete the entire design.Keywords： Worm; Finite Element; Analysis Screw drive; Simulation;Three-dimensional modeling目 录 TOC \o 1-3 \u 第1章 绪论 PAGEREF _Toc387150466 \h 11.1 起重机械 PAGEREF _Toc387150467 \h 11.2 千斤顶 PAGEREF _Toc387150468 \h 11.3 国内外千斤顶发展情况 PAGEREF _Toc387150469 \h 11.4 研究目的 PAGEREF _Toc387150470 \h 11.5 设计规格 PAGEREF _Toc387150471 \h 21.6 设计原理 PAGEREF _Toc387150472 \h 21.7 使用方法 PAGEREF _Toc387150473 \h 2第2章 丝杠传动的设计和计算 PAGEREF _Toc387150474 \h 32.1 丝杠传动 PAGEREF _Toc387150475 \h 32.2 丝杠传动的结构及材料 PAGEREF _Toc387150476 \h 42.2.1 丝杠传动的结构 PAGEREF _Toc387150477 \h 42.2.2 丝杠传动中常用材料 PAGEREF _Toc387150478 \h 42.3 丝杠传动的设计计算 PAGEREF _Toc387150479 \h 62.3.1 耐磨性与自锁性计算 PAGEREF _Toc387150480 \h 62.3.2 螺杆的强度计算
