摘要该设计的对称传动剪板机，其冲剪力为10吨，滑块的行程为22mm，每分钟剪切30次。由电动机提供动力，经过一级带传动和一级齿轮传动减速。设计中采用的执行机构为对心曲柄滑块机构，这一机构将剪板机传动系统的旋转运动转变为滑块的往复直线运动，实现对板料的剪切。曲柄滑块机构具有结构简单、加工容易、维修方便、经济实用的优点，在机械设备中应用广泛。本设计中，通过对平面曲柄滑块机构的数学建模，用TurborC编程，输入曲柄滑块机构的机构参数和运功参数，实现对整个机构运动过程的仿真。关键词：TurborC运动仿真曲柄滑块剪板机AbstractThedesignofsymmetrictransmissionshears,shear-to10tons,theitineraryfortheslider22mmper30minutesshear.PoweredbythemotorthroughabeltdriveandaslowdownGear.Designoftheimplementationagenciesrightmindcrankslider,Thiswillshearstransmissionrotationsliderintothereciprocatinglinearmotion,therealizationoftherightofsheetmetalshear.Cranksliderissimpleinstructure,easyprocessing,easytomaintainandrepair,economicandpracticaladvantagesinmachinery,equipmentwidelyused.Thedesign,rightthroughtheplanecrankslidermathematicalmodeling,TurborCprogramming,inputslidercrankagenciesthatsuchremarksparametersandtheparametersofthewholemovementofthesimulationprocess.Keywords:TurborCMotionsimulationCrankandslideblockCuttingmachine目录摘要.................................................................IAbstract............................................................II第1章绪论.........................................................1第2章方案论证.....................................................22.1液压传动方案..........................................22.2机械传动方案..........................................32.2.1凸轮机构方案............................................32.2.2曲柄滑块机构方案........................................4第3章总体传动方案.................................................5第4章电动机的选择.................................................64.1电动机类型和结构形式的选择................................64.2电动机功率的选择..........................................64.3计算传动装置的运动和动力参数.............................84.3.1计算传动装置的合理传动比................................84.3.2计算运动和动力参数......................................8第5章带传动的设计及计算..........................................105.1确定计算功率.............................................105.2选择带型.................................................105.3确定小带轮的基准直径.....................................105.3.1初选小带轮的基准直径...................................105.3.2验算带的速度...........................................115.3.3计算从动轮的基准直径...................................115.4确定中心距和带轮的基准长度.............................11a5.5验算主动轮上的包角.......................................125.6确定带的根数.............................................135.7确定带的预紧力...........................................135.8计算带传动作用在轴上压轴力...............................145.9带轮结构的设计...........................................145.9.1小带轮的结构设计.......................................145.9.2大带轮的结构设计.......................................16第6章轴的设计....................................................196.1主动轴设计...............................................196.1.1轴的材料...............................................196.1.2轴径的最小许用值...................
