Abstract
A gear drive, such as for an actuator, is a right-angle drive where toothed outer ridge of a face gear is coupled to teeth of a motor output shaft, and a set of planetary gears are engaged with a central sun gear of the face gear. The sun gear and planetary gears are aligned with the motor output shaft. For instance the motor output shaft may be substantially in the same plane with the sun gear and the planetary gears. From another standpoint the axis of the motor output shaft may intersect the sun gear, as well as intersecting a volume that the planetary gears sweep through as the planetary gears engage the sun gear.
