Abstract
The article presents selected problems related to an analysis of damage to wind turbine planetary gear. It is the most vital element installed in wind turbines, affecting the operational costs (prolonged downtime), and costs of repairs and servicing including delivery of required components. The authors have analyzed the wear/failure of planetary gear. The process initiating fatigue wear, different from similar devices in other industries, can be easily observed in wind turbine gear. This establishes a specific direction of research into the causes, and early detection of ‘gas spots’ on gear teeth as they seem to trigger fatigue wear.

The results show that the moving mesh has a strong effect on the planetary gear when the flexibility of the gears is taken into account
Summary
The ice load induced structural failure is one of the main types of damage of offshore structures [11] Such conditions can have a huge impact on the process of power and force transmission in a wind turbine gearbox, shafts and all connections. The purpose of such understanding is to prevent (or delay) the failure by taking certain precautionary and pre-emptive measures that can help to improve performance of the component, and not just opting blindly for enhanced design quality, making its production difficult and expensive [14] Steel acquired in such a way has a great influence on gearbox components working condition and its reliability
