Abstract. In this paper an energetic analysis for the application of a concentric magnetic gearbox (MG) have been carried out. MGs are able to work without contact to minimize acoustic noise and frictions with the advantage of reducing maintenance and increasing the global efficiency of the system. Concentric MGs are useful to a wide

In this study, the gearbox of a 4.2 MW wind turbine with both two-stage and single-stage helical PGSs was the base model. The first and second stages of the PGS comprise five and three planets

Pros. Bevel gears are compatible with wind turbine systems with right-angle configurations. The most beneficial aspect of bevel gearboxes is their ability to be used where a right-angle gearbox is required. Cons. The cut of the poor teeth can cause noise and strong vibrations. So, if the teeth are not properly cut, noise and vibrations will

The model running time was increased from 6000 to 60,000 s to clearly see when thermal equilibrium is reached. It should be highlighted that due to the variable nature of wind turbine operation, a wind turbine gearbox would rarely be in

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

In order to reach the correct rotational speed and generate power at the frequency needed by the grid you will need to use a gearbox between the main shaft (connected to the blades) and the secondary, "high speed" shaft linked to the rotor in the generator. The conversion ratio depend on the WTG model, but can be around 1:100.
