ABSTRACT:
An actuator for a speed control device is provided. The actuator includes a motor, first and second planetary gear assemblies, and an output shaft. The motor drives a shaft on which a first pinion is mounted. The first pinion, in combination with an internal gear, causes a first planetary gear to rotate which in turn causes rotation in a first carrier supporting the first planetary gear. Rotation of the first carrier causes a second pinion disposed on an opposite side of the first carrier to rotate. The second pinion, in combination with the above-mentioned internal gear, causes a second planetary gear to rotate which in turn causes rotation in a second carrier supporting the second planetary gear. Rotation of the second carrier is transmitted to the output shaft directly or through an intermediate clutch.
