盘磨机传动装置设计 【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,传动效率高,工作可靠、使用寿命长; 3、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 Pd=5.5kW i=32 i3=3.5 i0=9.14 i1=3.5 i2=2.6 nⅠ=1440 rmin nⅡ=411.4rmin nⅢ=158rmin n主=45rmin PⅠ5.34kW PⅡ5.07kW PⅢ4.82kW PⅣ====4.35 kW TⅠ=35.4N·m TⅡ118N·m TⅢ== 与数控技术的发展,使得机械加工精度,加工效率大大提291N·m 高,从而推动了机械传动产品的多样化,整机配套的模块T主=化,标准化,以及造型设计艺术化,使产品更加精致,美923N·m 观化。 [σH]1=715 在21世纪成套机械装备中,齿轮仍然是机械传动的基MPa 本部件。CNC机床和工艺技术的发展,推动了机械传动结[σH] 构的飞速发展。在传动系统设计中的电子控制、液压传动、Mpa 齿轮、带链的混合传动,将成为变速箱设计中优化传动组合m=10 的方向。在传动设计中的学科交叉,将成为新型传动产品发δ1=16° 展的重要趋势。 【关键词】 减速器 轴承 齿轮 机械传动 The Design of The Plate Mill’s Gear Jia Genqin Class of 0601 Machinery Manufacturing δ2=74° d1=100mm d2=350mm d a22=725 =355.4mm f2Abstract:Wheel gear’s spreading to move is a the most d =wide kind of the application spreads to move a form in the 343.25mm modern machine.Its main advantage BE: R=182mm 1、spreads to move to settle, work than in a moment b=50mm steady, spread to move accurate credibility, can deliver θa1=θa2=space arbitrarily sport and the motive of the of two stalks;3° Power and speed scope; 2、applies are wide; θf1=θf2=4° δa1=19° spreads to move an efficiency of, soon and deliver δa2=77° a function of turning , the application is extremely δf1=12°extensive in the modern machine. δf2=70° Local deceleration machine much with the wheel gear V=0.83ms spread to move, the pole spread to move for lord, but m=3 widespread exist power and weight ratio small, or spread d1=75mm to move ratio big but the machine efficiency lead a low d2=195mm problem.There are also many weaknesses on material b2=75mm quality and craft level moreover, the especially large b1=80mm deceleration machine’s problem is more outstanding, the a=135mm service life isn’t long.The deceleration machine of abroad, d a1=81mm with Germany, Denmark and Japan be placed in to lead a d a2=position, occupying advantage in the material and the 201mm manufacturing craft specially, decelerating the machine d f1=work credibility like, service life long.But it spreads to 67.5mm move a form to still take settling stalk wheel gear to spread d f2=to move as lord, physical volume and weight problem, 187.5mm don’t also resolve like V=1.61ms The direction which decelerates a machine to is the m=2 facing big power and spread to move ratio, small physical d1=50mm volume, several in the last yearses, control a technical d2=176mm development because of the modern calculator technique b2=50mm and the number, make the machine process accuracy, b1=55mm process an efficiency to raise consumedly, pushed a a=113mm machine to spread the diversification of movable property d a2=article thus, the mold piece of the whole machine kit turns, 180mm standardizing, and shape design the art turn, making d f1=45mm product more fine, the beauty turns. d f2=
