Patent ID: 8192323

Claim:
An epicyclic gear system comprising; a sun gear located along a central axis; a ring gear located around the sun gear and centered with respect to the central axis; planet gears located between and engaged with the sun and ring gears for rotation about offset axes; and a carrier also centered with respect to the central axis, the carrier including a carrier wall and flexpins that project from the carrier wall into the planet gears along the offset axes for the planet gears, each flexpin having an inner pin provided with flange that projects radially outwardly with respect to the offset axis of its planet gear and overlies the carrier wall, with the inner pin at its flange being secured to the carrier wall with machine screws, so that the inner pin is cantilevered from the carrier wall, and a sleeve that encircles the inner pin and is cantilevered from the inner pin remote from the flange, so that the flexpin provides a double cantilever, the carrier also including a bearing located between the sleeve of each flexpin and the planet gear into which the flexpin projects.
