0.业设计.设计题目:基于solidworks的圆柱齿轮减速机设计与虚拟装配系别：教育部系班级：08机械制造与自动化2班姓名：指导教师:2012年 6月 7日二级圆柱齿轮减速机的齿轮传动摘要齿轮传动是现代机械中应用最广的一种传动形式它的主要优点是：①瞬时 传动比恒定、工作平稳、传动准确可靠，可传递空间任意两轴之间的运动和动力； ②适用的功率和速度范围广；③传动效率高，no. 92-0. 99；④工作可靠、使用 寿命长；⑤外轮廓尺寸小、结构紧凑由齿轮、轴、轴承及箱体组成的齿轮减速 器用于原动机和工作机或执行机构之间起匹配转速和传递转矩的作用在现代机械 中应用极为广泛国内的减速器多以齿轮传动、蜗杆传动为主，但普遍存在着功率 与重量比小，或者传动比大而机械效率过低的问题另外，材料品质和工艺水平上 还有许多弱点，特别是大型的减速器问题更突出，使用寿命不长国外的减速器， 以德国、丹麦和日本处于领先地位，特别在材料和制造工艺方面占据优势，减速器 工作可靠性好，使用寿命长但其传动形式仍以定轴齿轮传动为主，体积和重量问 题，也未解决好当今的减速器是向着大功率、大传动比、小体积、高机械效率以 及使用寿命长的方向发展。

减速器与电动机的连体结构，也是大力开拓的形式，并 已生产多种结构形式和多种功率型号的产品近十几年来由于近代计算机技术与数 控技术的发展，使得机械加工精度，加工效率大大提高，从而推动了机械传动产品 的多样化，整机配套的模块化，标准化，以及造型设计艺术化，使产品更加精致， 美观化在21世纪成套机械装备中齿轮仍然是机械传动的基本部件CNC机床和 工艺技术的发展推动了机械传动结构的飞速发展在传动系统设计中的电子控制、 液压传动、齿轮、带链的混合传动将成为变速箱设计中优化传动组合的方向在传 动设计中的学科交叉将成为新型传动产品发展的重要趋势关键字：减速器轴承 齿轮机械传动Wheel gear' s spreading to move is a the most wide kind of the application spreads to move a form in the modern machine・ Its main advantage BE:The ① spreads to move to settle work than in a moment steady spread to move accurate credibility can deliver space arbitrarily sport and the motive of the of two stalks； Power and speed scope② applies are wide； (3) spreads to move an efficiency high n 0.92-0.98； ④ work is dependable service life long； ⑤ Outline size outside the is small strueture tightly packed. The wheelgear constituted to° ；；； from wheel gear stalk bearings and box body decelerates a machine use ding for prime mover and work machine or performance organization of have already matched to turn soon and deliver a function of turning the application is extremely extensive in the modern machine・⑥ Local deceleration machine much with the wheel gear spread to move the pole spread to move for lord but widespread exist power and weight ratio small or spread to move ratio big but the machine efficiency lead a low problem. There are also many weaknesses on material quality and eraft level moreover the especially large deceleration machine' s problem is more outstanding the service life isn' t long. The deceleration machine of abroad with Germany Denmark and Japan be placed in to lead a position occupying adva nt age in the mat erial and the manufac tu ring era ft specially decelera ting the machine work credibility like service lifelong. But it spreads to move aform to still take settling stalk wheel gear to spread to move as lord physical volume and weight problem don' t also resolve like The direction which decelerates a machine to is the facing big power and spread to move ratio small physical volume high machine efficiency and service life to grow greatly nowadaysdevelops・ Decelerating the connecting of machine and electrie motor body strueture is also the form which expands strongly and have already produced various st rue ture forms and various produc ts of power model numbers・ Be close to ten several in the last yearsescontrol a technical development because of the modern calculator technique and the number make the machine process accuracy process an efficiency to raise consumedly pushed a machine to spread the diversification of movable property article thus the mold piece of the whole machine kit turns standardizing and shape design the art turn making product more fine the beauty turns・ Become a set a machine material in 21 centuries medium the wheelgear is still a machine to spread a dynamic basic parts. CNC tool machine and the eraft technical development pushed a machine to spread to move strueture to fly to develop soon. Be spreading to move the electronics control liquid in the system design to press to spread to move wheel gear take the mixture of chain to spread to move will become soon a box to design in excellent turn to spread to move a combination of direction. The academics that is in spread move the design crosses will become new spread a movable property article the important trend of the development.
