版本：doc 机械设计专业毕业论文 论文题目：钢丝绳电动葫芦提升系统设计 摘要 电动葫芦是起重设备的主要型号之一。它主要由减速器，运行机构，卷筒装置，吊钩装置，联轴器，限位器，锥形转子电动机等部分组成。本文根据设计任务书要求，主要对3t单钩移动电动葫芦的总体方案选择和确定，然后对传动系统进行设计。根据设计要求和目的，参考CD型电动葫芦首先对3t单钩移动电动葫芦进行工艺分析，选择合理机构及装配方案，然后对减速器和电动机进行外形设计，钢丝绳的选用及强度验算，卷筒的参数计算及验算，再计算齿轮的传动比，确定各个齿轮的参数，进行强度计算,选择合理的轴承、键、轴套等各种零部件，画出总体装配图。最后对弹性联轴器作了一些简明的阐述。关键词：电动葫芦，卷筒装置，吊钩 Abstract 　Electric hoist is one of the main models of lifting equipment. It is mainly f the reducer, running organizations, drum installation, hook device, the coupling stopper, conical rotor motor and other components. According to the design task demands, this book mainly Against to 3t mobile electric hoist single hook selection and determination of the overall program, and then design the transmission system. According to the requirements and objectives of the design, reference CD-type electric hoist on the first take the 3t mobile electric hoist with the single hook for the process analysis, select reasonable organization and assembly programs, then design the shape of the reducer and electric motor, selection of wire rope and strength checking, reel The parameter calculation and checking, and calculate the gear transmission ratio, to determine the parameters of each gear, the strength calculation, select a reasonable bearings, keys, bushings and other components, to draw general assembly drawing. Finally, the tire type flexible coupling made some brief elaboration.
