Aircraft Propeller Reduction Gearing and Propeller Shafts

The thrust of the bevel pinion gears is absorbed by a thrust ball bearing of special design. The drive and the fixed gears are generally supported by heavy-duty ball bearings. This type of planetary reduction assely is more compact than the other one described and, therefore, can be used where a smaller propeller gear step-down is desired.
