一种桥式起重机小车机构的设计和计算

Design and Calculation of a Bridge Crane Trolley Mechanism

本文设计的桥式起重机是水电站桥式起重机,安装于丰满水电站扩建工程厂房内,用于水轮发电机组及其附属设备的安装和检修工作。水电站内设备一般都是大中型设备,对桥式起重机的载荷要求较高,对减速器性能要求较高,因此,本文选用三合一减速器,并对减速器进行了相关的计算验证。

The bridge crane designed in this paper is a hydropower station bridge crane installed in the expansion project of Fengman Hydropower Station for the installation and maintenance of the hydro-generator unit and its ancillary equipment.The equipment in the hydropower station is generally large and medium-sized equipment,which has higher load requirements on the bridge crane and higher requirements on the performance of the reducer.
