1、 1 摘摘 要要 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 JM0.5 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
2、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：关键词：卷扬机，卷筒，卷筒轴，减速器 2 Abstract Also known the hoist another name is winch.
