ABSTRACT:
The invention relates to gears and gear trains, and more particularly to epicyclic gear trains of low cost and improved efficiency. A novel driving means in the form of an eccentric crank/counterweight is provided, and the structural relationships between the several gears are such that the need for conventional bearings is completely obviated. The gear train is of modular construction, being split diametrically into matched halves. Thus, the gear ratio of the overall gear box may be quickly and easily varied by merely replacing one of the matched halves with another. A novel tooth construction for use with epicyclic gearing is also disclosed, wherein a large pressure angle allows circular arc profile involute teeth to be utilized.
