Research on the Faults due to Bearing-Gear Mismatching in Gearbox of Wind Turbine Generator

Abstract:

In order to lower down the fault rate of bearings and gears, tighten up the mechanical components safety and lengthen their lifetime, a new design method ^[ has occurred by matching bearings with gears. Whereas, this methodology is based on the simple transmission system, and it seems not applicable in more complicated transmission systems, such as gearboxes in doubly-fed wind turbine generators, which really need to be further studied, and thats where the topic of this article lies. By doing research on the bearing-gear matching design of planetary gear system in gearbox of wind turbine generator, equations are worked out. Succeedingly, by verifying the data from simulating experiments and on-site cases, it turns out that the spectrum characteristics of those two kinds of data match with each other correctly, and as a consequence, the new matching design is thus proved to be available.
