International Classification:

F04D 25/02

US Classification:

74665G, 74 11, 74 152, 74625, 415124

Abstract:

A rotator drive connection for a gas turbine engine accessory box has a shaft connected to be driven by a main shaft in a gas turbine engine through a gear train. A first drive connection allows selective drive of the shaft. A biased drive member includes a second drive connection selectively brought into contact with the first drive connection to allow rotation of the main shaft. The biased drive member biases the second drive connection out of contact with the first drive connection. A gas turbine engine accessory box and a method of borescopic inspection are also disclosed and claimed.

Assignee:

HAMILTON SUNDSTRAND CORPORATION - Windsor Locks CT

International Classification:

F16H 1/04

US Classification:

74460

Abstract:

An accessory gearbox assembly for an aircraft includes one or more intermeshed gears disposed in a gearbox housing and configured to transfer rotational energy from an engine core. An accessory component has a spur gear located at least partially in an accessory housing. The spur gear is meshed with a gear of the one or more gears thereby transferring rotational energy from the gearbox to the accessory component. A method for providing rotational energy to an accessory component at an accessory gearbox includes providing rotational energy to one or more intermeshed gears of an accessory gearbox and locating an accessory component at the accessory gearbox. The accessory component includes a spur gear disposed at least partially in an accessory housing. The spur gear is meshed with a gear of the one or more gears and rotational energy is transferred to the accessory component via the spur gear.
