巴西铁路货车轮对轴承压装装置设计探析

Study on the Design of the Wheel Pair and Assembling of Bearing Pressure Equipments of Brazilian Freight- trains

巴西GDE、GDT货车两种车型的轨距不同，它们与我国的标准轨距均不一致，其轴承与轮对的组装必须由固定式的压装机压装，其中包括压装力、贴合力及保压时间、压装曲线等必须自动记录及打印，此专用装备的设计值得探析。

The track gauges of Brazilian GDE and GDT freight-trains are different and they are not accordant to the standard track gauge in our country. The assembling of bearing and wheel pair must be pressed by fixed pressure devise, and pressure power, binding power, dwell time and the pressure curve etc. Which must be recorded and printed remotely. The design of the specific device is worthy of being studied.
