TORQUE SPLIT GEARBOX FOR ROTARY WING AIRCRAFT

摘要

A gearbox system for a dual coaxial counter rotating rotor assembly includes an input shaft to input a first torque into the gearbox system and a transfer shaft operably connected to the input shaft to transfer the first torque therethrough. Two gear sets are operably connected to the transfer shaft. Each gear set includes a first output gear to transfer a second torque acting in a first direction to a first rotor of a rotor assembly and a second output gear to transfer the second torque acting in a second direction opposite the first direction to a second rotor of the rotor assembly. The second torque transferred by each gear set of the two gear sets is substantially equal.

主权项

1. A gearbox system connectable to an exterior shaft which relays a first torque with respect to the gearbox, the gearbox system comprising:
an input bevel shaft operably connectable to the exterior shaft to transfer the first torque therethrough; and two gear sets operably connected to the input bevel shaft, each gear set including:
a first output pinion to transfer a second torque acting in a first direction to a first gear; anda second output pinion to transfer the second torque acting in a second direction opposite the first direction to a second output pinion coaxial with the first output pinion;wherein the second torque transferred by each gear set of the two gear sets is substantially equal.
