Abstract
A spur gear system wherein each gear comprises two gear sections; gear te in the respective sections are staggered a one half tooth pitch distance. The effect is to achieve a relatively high contact ratio with relatively small diameter gears. Teeth on mating gears are of positive (convex) curvature and negative (concave) curvature to provide an enlarged contact area.
