During the operation of the rotor shaft of the gas generator set, there will be journal wear. The standard size of journal is 129mm, the wearing state is elliptical, and the wearing depth is 0.5mm. Why do gas generators have neck wear problems? What are the consequences?

　　瓦斯发电机组转子轴在运行过程中，由于轴承已达到使用寿命或烧结事故损坏，未及时更换轴承。在没有轴承支撑的情况下，当轴和框架的壳体通过孔时，就会发生摩擦和磨损。

　　During the operation of the rotor shaft of the gas generator set, the bearing was not replaced in time because the bearing had reached the service life or was damaged due to sintering accident. In the case of no bearing support, friction and wear will occur when the shaft and frame shell pass through the hole.

　　孔与轴颈间隙约0.5mm，无相对运动。由于轴承损坏，轴颈与轴颈之间的支撑磨损，破坏了轴颈的表面圆度和整体强度，使间隙更具破坏性。在设备的长时间运行的过程,它是容易的污垢或颗粒杂物进入轴承滚道通过这个缺口,这将影响轴承的旋转精度或缩短轴承的使用寿命,因此创建安全隐患和连续运行的设备。

　　The clearance between the hole and the journal is about 0.5mm without relative movement. Due to the bearing damage, the support between the journal and the journal is worn, which destroys the surface roundness and overall strength of the journal and makes the clearance more destructive. In the process of long-term operation of the equipment, it is easy for dirt or particles to enter the bearing raceway and pass through the gap, which will affect the rotation accuracy of the bearing or shorten the service life of the bearing, so create a potential safety hazard and continuous operation of the equipment.

　　针对瓦斯发电机组轴颈磨损的现状，应如何进行维修?

　　In view of the present situation of the journal wear of gas generator set, how to maintain it?

　　除了一些传统修复技术,如更换新零件,修理焊接、刷镀、激光熔覆等,随着科学技术的发展已经索雷聚合物材料的碳修复技术,这项技术是类似于冷焊接技术,在线修复过程不产生热量,避免修复焊接工艺的热应力的影响,同时对轴向不均匀磨损量也没有严格的限制，且整个修复过程简单，修复效率高。

　　In addition to some traditional repair technologies, such as replacement of new parts, repair of welding, brush plating, laser cladding, etc., with the development of science and technology, the carbon repair technology of Solay polymer materials has been developed. This technology is similar to the cold welding technology, which does not generate heat in the online repair process and avoids the influence of thermal stress in the repair welding process, At the same time, there is no strict limit on the amount of axial uneven wear, and the whole repair process is simple and the repair efficiency is high.
