1·Repair and install railway car parts such as compressors, air valves, bearings, couplings, air cylinders and piping.
维修及安装铁路车辆部件如压缩机，空气阀，轴承，联轴器，气缸和管道。
2·There are no bearings to fail or requirements for flexible couplings because its magnetized drum assembly is attached directly to the shaft.
没有轴承失败或弹性联轴器的要求，因为它的磁化鼓大会直接连接到轴。
3·LD wheel, wheel group, drum group, hook group, pulleys, couplings, wire rope, cable pulley, motor, brake, reducer, cable reel, overload limiter, standard parts.
LD车轮，车轮组，卷筒组，吊钩组，滑轮组，联轴器，钢丝绳，电缆滑车，运行电机，制动器，减速机，电缆卷筒，超载限制器，标准件。
4·Old Method: High speed turbine couplings often utilize fitted bolts which can be difficult to install and remove.
传统方法：高速涡轮机联轴器经常要采用紧配螺栓，而紧配螺栓的安装和拆卸都非常麻烦。
5·Moreover, in this paper we analyse the initial failure of bolt connection in gear couplings.
文中对齿轮联轴器的连接螺栓的早期失效进行了分析。
