小型拖拉机整理车架设计（含全套CAD图纸）.rar

摘要汽车工业是一个国家的重要产业,***的发展无时不刻都在影响着国家经济的发展,人类的进步离不开***的发展。在全球经济发展的大环境下, 中国各个行业被其他国家的先进技术影响的同时,越来越多的外国企业和品牌传播到中国已经成为现实。在新的市场需求的推动下,对小型拖拉机整体车架进行改良和优化是当务之急。生产小型拖拉机整体车架的企业,必须充分考虑到在小型拖拉机整体车架运行中可能出现的问题,尽量使小型拖拉机整体车架的标准化程度越高越好,稳定和强度越来越好,国内小型拖拉机整体车架的研发及制造要与全球号召的稳固牢靠、性能稳定主题保持一致。小型拖拉机整体车架的发展与人类社会的进步和科学技术的水平密切相关。本次设计在题目是小型拖拉机整体车架的设计,目前,国内小型拖拉机整体车架的研发也在向朝着结构多样化、功能复合化、强度稳定化的方向发展,廉价, 简单,方便成了小型拖拉机整体车架发展的主题。关键词: 机械产品小型拖拉机整体车架制造主题 1 Abstract This graduation design is the optimization design of driving roller conveyor, first on the driving roller type conveyer is summarized; then analyzed the selection principle and calculating method of driving roller conveyor; then calculated based on these design criteria and abase is designed; then checked on the main parts selected conveyor. Is the drive roller conveyor consists of four main parts: driving device, tension device, middle rack, and the moving part. Finally, a simple description of the installation and maintenance of transport. At present, the drive roller conveyor is moving towards long distance, high speed, low friction direction, air cushion conveyor in recent years isone of the. the motion trajectory when the diagonal curve is slanting line do the walking motion, robot. The miniature walking robot is mainly driven by DC servo motor, so as to drive the leg action driven synchronous belt wheel bya crank and rocker mechanism. In the design, driving roller type conveyer manufacture and application, at present our pared with foreign advanced level there are still large gaps, domestic in the design and manufacture of driving .This design is the optimization design of driving roller conveyor .
