1、内蒙古科技大学毕业设计说明书(毕业沦文)胶粉车间用卷扬机的改进设计摘要卷扬机又称绞车。是起重垂直运输机械的重要组成部分,配合井架、桅杆、滑轮组等辅助设备,用来提升物料、安装设备等作业,由人力或机械动力驱动卷筒、卷绕绳索来完成牵引工作的装置。垂直提升、水平或倾斜曳引重物的简单起重机械。分手动和电动两种。现在以电动卷扬机为主。本次设计的JMO.5吨卷扬机是由电动机、液压推杆制动器、制动器、电磁铁制动器、卷筒等组成。本次设计的步骤是从钢丝绳开始入手,然后依次对卷扬机的卷筒、卷筒心轴、电动机、减速器齿轮、减速器轴、制动器设计与选取。本
2、次设计的卷筒机由于它结构简单、搬运安装灵活、操作方便、维护保养简单、对作业环境适应能力强等特点,可以应用于冶金起重、建筑、水利作业等方面,但是此次设计的卷筒机主要运用于用于5吨桥式吊车起升机构。提升重物是卷扬机的一种主要功能,各类卷扬机的设计都是根据这一要求为依据的。关键词:卷扬机,卷筒,卷筒轴,减速器-VI-内蒙古科技大学毕业设计说明书(毕业沦文)RubberpowderworkshoptoimprovethedesignofthewinchAbstractThehoisthasbeenknownasthewinch.Lif
