剪式千斤顶设计.doc

摘要： 汽车千斤顶是汽车日常更换轮胎、简单维护必不可少的重要举升工具。随着我国经济的高速发展，人民生活水平的逐步提高，使用汽车的家庭变得越来越多，这就使得千斤顶的需求量日益增多，而如何简单方便快捷的给汽车更换轮胎这个问题则需要我们进行进一步的研究。本篇论文中提出了一种结构简单、起重重量大且稳定的剪式千斤顶设计方案，本方案对剪式千斤顶技术进行深入分析研究，其工作原理是：使用者手动摇动螺杆旋转，带动套筒和举臂升降，从而达到起重汽车的目的。剪式千斤顶作为一种新型的汽车千斤顶，对此进一步的研究也是不能忽视的。 关键词：千斤顶；汽车；螺旋传动 Abstract The car jack is an important lifting tool for car daily replacement tires, simple maintenance essential. With the rapid development of Chinas economy, the gradual improvement of peoples living standards, the use of car families become more and more, which makes the increasing demand for jacks, and how simple and convenient to replace the car tire problem We carry out further research. In this paper, a simple, heavy-weight and stable shear jack design scheme is proposed. The working principle of the scissor jack technology is as follows: the user manually shakes the screw rotation and drives the sleeve Tube and lift arm lift, so as to achieve the purpose of lifting a car. Scissor jack as a new type of car jack, this further study can not be ignored.
