Abstract: A gearbox assembly includes a plurality of planet gears and a planet carrier including a plurality of planet gear pockets. Each planet gear is mounted in a respective planet gear pocket about a pin. The planet carrier is characterized by a planet carrier envelope in a range of 2.7 and 4.50. The planet carrier envelope is equal to a product of a planet gear pocket aspect ratio multiplied by a planet carrier radial ratio. The planet gear pocket aspect ratio is Dp/L. The planet carrier radial ratio is D/aw. Dp is a planet gear pocket diameter of the plurality of planet gear pockets, L is a planet gear pocket length of the plurality of planet gear pockets, D is a planet carrier diameter of the planet carrier, and aw is a pin center distance from a longitudinal axis of the planet carrier to an axis of the pin.

Abstract: An epicyclic gearbox that includes a sun gear, a ring gear, and a plurality of planet gears. The planet gears rotatably couple to the ring gear and the sun gear. Pins coupled to or formed as part of a carrier extend into the planet gears. A sleeve overhangs a notch defined, in part, by at least one of the pins. The pins, the carrier, the sleeve, or any combination of one or more of the pins, the carrier, or the sleeve are capable of flexing.

Abstract: A gearbox assembly includes a gear assembly that includes a planet gear, a pin disposed within the planet gear, a first sensor, and a second sensor. The first sensor is disposed within the pin and is configured to produce a signal indicative of a strain of the pin. The second sensor is disposed within the pin and is configured to produce a signal indicative of a vibration of the pin. Another gearbox assembly includes a gear assembly including a planet gear, a pin disposed within the planet gear, and a strain sensor. The strain sensor is disposed within the pin and is configured to produce a signal indicative of a strain of the pin. The strain sensor is located within the pin at a circumferential location of the pin that is opposite to a location of a force acting on the pin when the planet gear rotates about the pin.
