摘要： A cranking pad assembly for a gearbox of a turbomachine including a cranking pad shaft rotatably secured in a gearbox housing and engageable with a gearbox drivetrain when urged inwardly into the gearbox housing. The cranking pad shaft includes an interface for a cranking tool. An interlock pin retains the cranking tool at the cranking pad shaft and a disconnect spring is operably connected to the gearbox housing to bias the cranking pad shaft outwardly from the gearbox housing.

摘要： 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.

摘要： A lightweight and compact apparatus is provided for altering and controlling the pitch of a plurality of rotating blades during rotation using a mechanical clutch and gear arrangement driven by a rotational speed differential between the blade drive shaft and the blades. A first set of clutches and gears controls the direction of rotational power to the pitch change mechanism and is disengaged from rotation when desired blade pitch is established. A second set of clutches and gears controls the speed of rotational power applied to the pitch change mechanism. This pitch change mechanism includes a failsafe capability against pitch change through disengagement of the directional clutches except when needed, and an inherent rotational lock resulting from the rate change clutches' bias to simultaneous engagement. Variation of that speed of rotational power permits coarse and fine pitch adjustments at variable rates.
