ABSTRACT:
A geared rotary actuator (1) including a compound input stage (3, 5) and a compound output stage (4, 6) with the input stage (3, 5) including a sun gear (24) with gear portions (24a, 24b) respectively meshing with a drive gear (23) and further gear (25). Input/output link members (28, 29) connect the input stage (3, 5) with planet gears (26, 27) of the output stage (4, 6) so as to provide uninterrupted controlled speed, torque and power delivery to an output (31, 32) and through shaft (S) of the geared rotary actuator (1) even upon an occurrence of a jam in the geared rotary actuator (1).
