Patent Summary

Wind turbine gearbox with a radial-moving-teeth design that achieves higher gear ratios per volume and weight compared to traditional gearboxes. The design features radially movable tooth segments that engage with a fixed ring gear, driven by an annular input member, to produce a high-speed output. The tooth segments are connected to tilting pads that slide along the output member, allowing for adjustable transmission ratios. The system eliminates backlash and achieves precise positioning, making it suitable for wind turbine applications.
