A high speed gearing assembly includes at least two interengaged composite gears having spur or single helical teeth. Each of the gears is formed of three annular gear parts which rotate about a common axis. The gear parts are juxtaposed in side by side relationship. The central part of each gear is offset relative to its adjacent end parts approximately one half a pitch length. Each end part is approximately one half the width of the central part. With a ratio of tooth engagement length to circular pitch length, i.e. the degree of overlap, of approximately 1.5, increased load capacity, steady running and reduced noise levels are attained. |
