Abstract

Tooth interior fatigue fracture (TIFF), as the typical failure mode of carburized wind turbine gear, is one of the major limitations to improve the service performance of wind turbine gearbox. This work developed a TIFF reliability analysis model of carburized gear based on the stress-strength interference fuzzy function and material strength degradation theory. The equivalent stress is calculated using load duration distribution method and Dang Van multiaxial fatigue criterion. The model is verified by comparing with gear failure sample coming from a 2MW wind turbine. The effects of gear hardness gradient and micro-modification on TIFF is discussed in detail. The optimization of design parameters is obtained with the regression equation of material exposure. The results show that the core hardness and lead crown are the main influencing factor of TIFF. With the developed optimizing design, the TIFF reliability of discussed gear pair is improved from 0.968399 to 0.972678.
