ABSTRACT:
The present invention comprises a balancing gear assembly employed to statically balance a camera or like equipment mounted upon angular positioning equipment. Remote angular positioning equipment for a camera or other similar devices permits remote angular positioning along the perpendicular axes of rotation of the equipment. The driving force to the camera along each of the two axes is supplied through a separate driving gear. The present invention balancing gear apparatus is disposed between each of the drive gears and the power source for rotating the drive gear. The power source is coupled to a worm gear through a universal joint which permits 360.degree. rotation of the shaft upon which the worm gear is mounted. The worm gear is appropriately journaled within a yoke which is moveable in the plane of the drive gear. The yoke supporting the rotatable worm gear can be positioned to engage the worm gear and the drive gear during operation. Moving the yoke to the alternate position disengages the worm gear and the drive gear leaving the camera equipment disengaged from the motive force and permitting static balancing of the camera in the respective plane of movement.
