ABSTRACT:
This invention is in concern of a gear means for control of planet projectors in planetaria which does without a continuous year's axis shaft. The orbit speeds for the respective projectors are derived from the preceding one in such a manner that, by use of planetary gears and by definite transmission ratios of the toothed components, the speed is transmitted from the faster rotating projectors to the slower rotating projectors. The projectors are mounted on discs which are driven at the correct speed. The toothed components of the planetary gears are also seated on said discs. The toothed components mesh with gear wheels which are mounted on a tubular shaft which holds the entire gear arrangement, thus effecting the speed transformation. The inventional gear arrangement is used to simulate planet movements in planetaria.
