Abstract:
Rotary shaft driver apparatus in which a shaft is simultaneously driven by first and second actuators, the rotary shaft driver apparatus including a mechanism for splitting the actuator load between the first and second actuators, comprising:a support structure;an output shaft mounted for rotation relative to said support structure about a first axis with which said output shaft is aligned;a first actuator having first and second members which, upon energization, are rotated in opposite directions relative to one another, the first member of said first actuator being coupled to said output shaft for imparting rotation thereto;a second actuator having first and second members which, upon energization, are rotated in opposite directions relative to one another, the first member of said second actuator being coupled to said output shaft for imparting rotation thereto; anda coupling mechanism coupling the second members of said first and second actuators to one another at first and second spaced apart locations and to said support structure at a third location between the first and second spaced apart locations, whereby said mechanism permits limited counter-rotational movement between the second members of said first and second actuators, while precluding simultaneous rotation of the second members of said first and second actuators in the same direction relative to said support structure.
