基于proe螺旋千斤顶三维模型设计.doc

摘要
螺旋千斤顶是一种小型的起重设备,体积小方便携带,制造成本低,所以在日常生活中被广泛应用。
螺旋千斤顶主要由螺杆、螺母、手柄、底座、大伞齿轮、小伞齿轮、机架、棘轮组、升降套筒等零部件组装而成的。在本次设计过程中螺旋传动的计算和各零部件的设计与选材最为重要:并且重点运用了机械设计方面的知识,另外还运用了辅助绘图工具AutoCAD、Pro/E等由于某些原因,没有上传完整的毕业设计(完整的应包括毕业设计说明书、相关图纸CAD/PROE、中英文文献及翻译等),此文档也稍微删除了一部分内容(目录及某些关键内容)如需要的朋友,请联系我的叩扣:2215891151,数万篇现成设计及另有的高端团队绝对可满足您的需要.
本文从螺旋千斤顶的零部件的设计与选材等多方面,阐述了它设计的全过程。尤其在工艺规程设计中,运用了大量的科技加工理论及计算公式,对它进行了精确的计算。特别是在螺旋传动部分,通过对螺杆稳定性校核、螺母纹牙的计算、自锁性校核和各种强度计算。通过各种科学的计算使设计出来的螺旋千斤顶更加能够满足各种实际需要。

Abstract
As the spiral jack is a kind of lifting equipment ,besides ,it has small size portability ,and low cost ,so it is widely used in our daily life
Spiral jack is consist with screw , nut ,handle , base , large bevel gear , runlet gears ,rack ,ratchet set ,lifting the sleeve and other parts . It is most important to calculate the spiral driven and design and selection for the parts ,in this design process ;what is more ,used the knowledge of mechanical design ,in addition to used CAD tools such as AutoCAD Pro/E and so on
This article described the whole process of its design from the spiral jack design to the selection ponents and other aspects .It was precisely calculated because it used a large number of scientific processing theory and formula , especially in process planning . In the spiral transmission part , through the calculation of wear resistance , stability check of the screw , the calculation of the nut thread teeth ,self-locking of the check and variety of strength calculation .through a variety of scientific calculations the screw jack designed will meet the actual demand .In this design ,we used Pro/E to design a number of parts and transmission of three-dimensional modeling , it clearly show the various parts of the shape and structure .
Keywords; spiral、screw transmission 、AutoCAD、Pro/E
