Planetary gearhead

for aircraft

Woodward is an industry leader in the design and development of planetary gearing for aerospace and defense motion-control applications. FEATURES & FUNCTIONALITY Woodward is an industry leader in the design and development of planetary gearing for aerospace and defense motion-control applications. Size & Capacity Woodward offers planetary gearheads in an array of sizes in inch-series diameter codes from Size 8 to Size 80 (.8” to 8”) commensurate with our standard servo motors. We furnish these units as complete vehicle level line-replaceable units (LRUs), including hinge lines, as required by the overall system design philosophy. Woodward’s planetary gearhead features high torque capacity per unit weight and volume, as well as low backlash and high stiffness. The output bearing pair span in Woodward’s planetary gearhead architecture provides maximum radial stiffness against the mating forces of the payload. We can optionally supply the output pinion of the planetary gearhead split and torsionally spring loaded against itself, to eliminate backlash to the payload’s mating gear.
