Epicyclic gear system with flexpins

An epicyclic gear system (A) includes a sun gear, a ring gear located around the sun gear, planet gears organized in two arrays between the sun and ring gears, and a carrier having walls located beyond the planet gears and flexpins that project from the walls into the planet gears. Each flexpin includes an inner pin provided with a flange that is secured to the wall from which the inner pin projects, thus cantilevering the inner pin from the wall, and a sleeve that is cantilevered from the opposite end of the inner pin and extends back over the inner pin, thus providing a double cantilever. Between the sleeve of the flexpin and the planet gear for that flexpin is a double row tapered roller bearing. The planet gears on the one array may be offset angularly with respect to the planet gears of the other array.
