长轴式焊接滚轮架设计（机械CAD图纸）长轴式焊接滚轮架设计摘要在科学技术飞速发展的当今时代，焊接已焊接已经从一种传统的热加工技艺发展到了集材料、冶金、结构、力学、电子等多门类科学为一体的工程工艺学科。
而且，随着相关学科技术的发展和进步，不断有新的知识融合在焊接之中。
目前国内外众多的焊接设备制造厂都在生产焊接滚轮架。
产品规格型号多，结构差别大，各自适合不同的用途，各有特点。
国内的重型焊接滚轮架用户主要集中在大型石油化工、锅炉制造、电站设备制造、重型设备制造行业。
使用的焊接滚轮架来自不同的国家。
焊接滚轮架是借助工件与主动滚轮间的摩擦力来带动工件旋转的机械装置,主要用于回转体工件的装配与焊接。
本次设计题目是一台2吨长轴式焊接滚轮架。
长轴式焊接滚轮架多是用户根据焊件的特点自行设计制造，市场可供选用的产品很少。
考虑负载的压强取滚轮架宽度为1796毫米,综合考虑受力情况的大小取滚轮架长度为3445毫米。
其设计的主要内容包括：2吨长轴式焊接滚轮架的底座，主动滚轮机构、从动滚轮机构机械设计、装配图和零件图设计。
并编写相应的设计说明书。
对滚轮架、调整方式、传动方式等可采用不同的设计方案。
整个机械系统应简单可靠，操作方便、经济适用。

At present, lots of both national and inter national manuf actur ing plant all product welding roller carr ier. Ther e ar e numerous types f or differ ent structures with their own char acteristics to fit dif ferent use. The user of the national heavy welding roller car rier ar e mostly in the field of lar ge scale chemis tr y, manufactur e of the equipment in electronic generate factory, manuf actur e of heavy equipment. The welding roller car rier they use come f rom diff erent countr y.The welding roller car rier is a mechanic device to make the wor kpiece to rotate by the friction between the workpiece and the initiative r oller. It mostly used in the assembly and welding of the turning wor kpiece.This thes is is the design of along axis type welding roller car rier for 2 ton. The long axis type welding roller fr ame ar e mostly manuf actur ed by the user themselves because there are ver y few pr oduct in the mar ket.The width of the roller car rier is 1796the workpiece.Its length is3445mm considering mm considering the pressure ofthe condition of the load.This thesis mainly includes the design of long axis type welding roller fr ame base,the initiative roller device,the driven r oller device,assembly dr awings and detail dr awings of the f oundation,etc.The design specif ication is also needed.It could use diff er ent project to design the f oundation,the type of adjustment,the type of dr ive.The whole mechanic system should be reliable,simple,convenient毕业设计（论文）to operate and economical.KEY WOR DS：Welding,Roller car rier,Long axis type目录前言 (1)第1章§1.1§1.2第2章§2.1§2.2§2.3第3章第4章课题简介及焊接滚轮架发展史 (3)课题介绍 (3)国内外的发展现状 (13)焊接滚轮架的整体方案设计 (14)滚轮的选用 (15)滚轮架的选用 (15)焊接滚轮架拖动与调速方式 (16)电机的选择 (16)零件的校核 (20)§4.1§4.2轴的校核 (21)轴承与键的校核 (22)结论 (26)参考文献 (27)致谢 (28)前 言在人类社会步入二十一世纪的今天，焊接已经进入了一个崭新的发展阶 段。
