摘要本次设计的喷砂生产线运输小车是用在喷砂生产车间的运输装置。它能实现载物台的匀速转动和有轨移动。在设计中，首先通过对小车结构、承载能力及运行方式进行分析初步确定了小车的结构和外形尺寸。小车的回转装置采用了回转支承，并通过对比和选型计算确立了回转支承的型号。为节约系统空间，简化传动机构，小车采用了直流力矩电机作为驱动装置。另外对齿轮，轴承，车轮轴等进行了设计与校核，对小车的关键部位进行了结构有限元的分析。60937
通过对小车部分零件的改进和设计使小车结构更加简单、轻便，并且小车具有足够的承载能力，小车的设计将大大提高工厂的生产效率。

Title Design of transport bogie of sand blasting line
Abstract The design of the transport bogie of sand blasting line is used in sand blasting workshop with the transport unit within. It can realize trams running and stage of rotation. In the design of the first through the structure, bearing capacity and car movement way and analyzed, and preliminarily determines the structure and size of the car .The revolving of the car adopts slewing bearing and through the comparison and selection determines the slewing bearing calculated model. To save system space, simplify transmission mechanism, the car uses a DC torque motor as the drive device. In addition, the gear, bearing, and car wheel were designed with the verification. The key parts of the car are finite element structural analysis.
Through the improvement and design of some parts makes the car more simple structure, lightweight, and the car has sufficient carrying capacity. The design of the car will greatly improve the productivity of the plant.
