Abstract

This article describes a new design solution for a hybrid bearing intended for use in prosumer wind turbines with a vertical axis of rotation of the turbine rotor. The automatic rotational speed-dependent load-switching, lubrication and cooling systems applied in the hybrid bearing ensure a particularly long service life and highly quiet running while maintaining high energy efficiency over the full rotational speed range of shafts with turbine rotors. The hybrid bearing design has been adapted to the use of lubricating fluids with the lowest possible viscosity, including oil-water emulsions and even water itself. The use of water as a lubricant makes the bearing system highly environmentally friendly and completely fire-safe.
