US Patent 12018618 Mounting arrangement for a tension member driven system

An aircraft engine comprises a rotor, an engine case having first and second mounting brackets projecting from an exterior surface thereof, an auxiliary engine system. The system includes an electric machine, a belt drive operatively coupled to the rotor, and a gearbox operatively coupled between the belt drive and the electric machine. The gearbox has a gearbox case with a cradle integrated thereto. The gearbox case and the cradle forms a monolithic body. The monolithic body is pivotally mounted to the first and second mounting brackets. A link is provided between the engine case and the monolithic body. A length of the link is adjustable to adjust a tension of the belt drive by setting an angular position of the monolithic body relative to the engine case.
