ABSTRACT:
A geared rotary actuator (1 or 1') and method of assembling the same, with the geared rotary actuator (1 or 1') including a plurality of one-piece planetary gears (12 or 12'), each including a first set of gear teeth (19) meshing with a sun gear (11), and at least two additional sets of gear teeth (17, 18 or 17') respectively forming an inboard set of gear teeth and an outboard set of gear teeth respectively adapted to mesh with sets of gear teeth (13 or 13', 14 or 14'), of outboard and inboard ring gears. At least one tooth of the sets of gears (17, 18, 19 or 17', 19') are axially aligned along a length of the one-piece planetary gears (12 or 12') so as to enable the inboard ring to be moved axially past the outboard set of gear teeth (17 or 17') to mesh with the inboard set of gear teeth (18 or 17').
