Abstract
A timing gear assembly for a trochoidal rotary device comprises a dual set of like timing gear systems provided on opposite lateral sides of the rotor to prevent rotor wobble. The pair of timing gear systems are in balance and equally loaded in support of the rotor at all times during rotor movement; and the opposed timing gear systems are circumferentially offset relative to one another, either by virtue of relative circumferential displacement of the pinion gears or ring gears or both.
