Mounting accessories on a gearbox

摘要

A mount (9) for a gearbox accessory (50) for a gas turbine engine substantially isolates the accessory (50) from direct mechanical loading from the engine case (22) during normal engine operating conditions and couples the accessory (50) to the engine case (22) during high rotor imbalance conditions to minimize interface loads between the gearbox (40) and the accessory (50). By coupling the gearbox (40) to the accessory (50), the two are displaced substantially in unison, thereby minimizing interface stresses therebetween. Various construction details of the mount for the gearbox accessories (50) are disclosed. <IMAGE>
