  • Gearbox comprising a stationary gear component formed on the basis of variable flank profiles of gear teeth
    Patent number: 8613688
    Abstract: In a gearbox, a stationary gear component such as a ring gear of a planetary gear comprises a tooth trace correction that varies along the tooth trace so as to provide for superior load distribution in the gearbox. In some illustrative embodiments, the gearbox is a component of a wind power plant wherein the circumferentially varying tooth trace correction of the stationary ring gear results in superior durability and performance.
