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＝
