东北林业大学毕 业 设 计设计题目：桥式起重机小车设计学 生：李铎指导老师：孟春副教授学 院：工程技术学院专 业：森林工程 2024 级 3 班 2024 年 6 月 16 日桥式起重机小车设计摘要根据机械设计标准和起重机设计标准及各零部件的选择标准，依据所给参数和具体工作环境，设计出了桥式起重机小车各个机构。起升机构采纳电动机驱动，布置方式采纳电动机轴与卷筒轴平等布置。小车运行机构主动轮采纳对面布置方式，集中驱动。各零部件间采纳具有补偿性能的齿轮联轴器连接，带制动轮的联轴器安装在减速器的高速轴上，这样，即使联轴器被损坏，制动器仍可将卷筒制动，确保机构安全。为使起升机构布置方便并增大补偿能力，在电动机与减速器之间采纳浮动轴连接。带制动轮的半齿联轴器和制动器靠近减速器，万一浮动轴被扭断，制动器仍可以制动住卷筒。小车架有两根端梁和两根横梁组成，端梁焊接成箱形，在端梁与横梁上边焊有钢板，钢板上在安装电动机、减速器、制动器和轴承座的地方焊有垫板。关键词： 桥式起重机；起升机构；小车运行机构；小车架Trolley bridge crane designAbstractAccording to the mechanical design standards and design standards for cranes and other parts of the selection criteria, based on the given parameters and the specific working environment, the design of the bridge crane car agencies. Lifting bodies using motor-driven layout with the use of motor axis equal axis reel layout. Car driving wheel used to run institutions across the layout, concentrated drive. Between the various components of compensation with the performance of the use of the gear coupling to connect with the coupling wheel brake installed on the axis of high-speed reducer, so that even if the coupling has been damaged can be brake drum brake to ensure that security agencies. In order to facilitate the hoisting mechanism and increase the compensation arrangement of capacity between the motor and reducer with floating-axis connection. Semi-round with brake and brake gear coupling near the reducer, if...
