Abstract
An improved drive mechanism (100) adapted to be mounted on a support for controllably moving a first output shaft (16) about either or both of two orthogonal axes (T, E). The drive mechanism has a stationary lower portion adapted to be mounted on the support and having a movable upper portion mounted for movement relative to the stationary portion. The improved drive mechanism broadly includes: a first power train (10, 12, 2, 4, 14) for controllably rotating a first gear (6); a second power train (9, 11, 1, 3,13) for controllably rotating a second gear (5); and a third gear (7) connected to the first output shaft and meshing with at least one of the first and second gears. The first, second and third gears form a portion of a differential-like mechanism (18) mechanically coupling the first and second power trains to the first output shaft. The first and second power trains may be selectively operated to controllably and cooperatively move the first output shaft to a desired position relative to the support.
