Main generator shaft for high power locomotive

在设计发电机的转轴时，不仅需要满足结构要求，还需保证其具有足够的强度、刚度和振动稳定性。

It must not only be satisfied with structure requirement, but alsothe strength, stiffness and vibration steadiness. 

发电机转轴

Generator shaft

车用发电机轴上一般有两个轴承，分别支撑在驱动端盖和电动端盖上，驱动端带有轴伸，通过其上装配的皮带轮来输入动力。

The generator shaft of the vehicle is generally provided with two bearings, which are respectively supported on the drive end cover and the electric end cap. The driving end is provided with a shaft extension.

车用发电机一般归于用V型带传动的小型电机。

Motor generators are generally attributed to the V type with a small motor drive.

发电机轴伸上的皮带轮一般采用螺纹拧紧，这时螺纹联接受到预紧力的作用。拧紧力矩过大会造成轴上的螺纹失效，包括滑丝、压溃等。

The belt pulley on the shaft of the generator is generally adopted by screw thread, and the thread is connected with the function of the preload. Tightening torque caused by the General Assembly on the shaft thread failure, including slide, pressure, etc..
