Epicyclic gear speed change mechanism

Patent ·
OSTI ID:6733318
This patent describes a speed change pulley drive mechanism employing an epicyclic gear train with a ring gear, multiple planet gears and a sun gear, input and output members, and a clutch operable to either directly connect the input and output rotary members or indirectly connect the input and output members through the epicyclic gear train. The improvement described here comprises means supporting the sun gear for preventing rotational movement while permitting only limited radial movement and for relatively uniformly engaging the multiple planet gears.
