  • Gearbox accessory mount
    Patent number: 6357220
    Abstract: A mount for a gearbox accessory for a gas turbine engine substantially isolates the accessory from direct mechanical loading from the engine case during normal engine operating conditions and couples the accessory to the engine case during high rotor imbalance conditions to minimize interface loads between the gearbox and the accessory. By coupling the gearbox to the accessory, the two are displaced substantially in unison, thereby minimizing interface stresses therebetween. Various construction details of the mount for the gearbox accessories are disclosed.
