1、图书分类号:密级:毕业设计(论文)三层货运电梯曳引机及传动系统设计TODESIGNTRACTORANDTRANSMISSIONSYSTEMOFTHREEFREIGHTELEVATOR学生姓名学院名称专业名称指导教师20**年5月27日摘要电梯的曳引机主要是由曳引绳、电动机、减速器、曳引轮、制动器和联轴器组成。根据电梯运行的速度和载荷来选用电动机和制动器。曳引绳的设计,首先选用一种曳引绳的绕法,再由它的受力情况来选择曳引绳的数量和截面积。减速器是设计的主体部分,要根据电动机的转速、电梯的运行速度、曳引轮的直径等参数设计减速器。电梯是利用曳引钢丝绳与曳引轮缘上绳槽的摩擦力传
2、递动力,所以必须设计表面摩擦系数大且耐磨的曳引轮。选用刚性联轴器,保证传递的动力,但要求两轴的对中度较高。关键词货运电梯;曳引机;组成;设计IAbstractElevatortractionmachinemainlybythetractionrope,motor,reducer,tractionwheels,brakesandcouplingcomponents.Theoperatingspeedoftheelevatorandloadtheselectionofmotorandbrake.Thedesignofthetractionrope,firstchooseat
