Abstract:

A power drive unit for aircraft cargo handling systems that includes a motor and a drive roller carried for engagement with cargo to be driven by the unit. Planetary gears rotatably couple the output shaft of the motor to an output gear coaxial with the motor output shaft. Idler gears extend laterally from the planetary output gear and rotatably couple the planetary output gear to the roller drive shaft. A pair of angularly spaced reaction gears are coupled to the planetary output gear in opposition to the idler gears for supporting the output gear against reaction forces imparted thereto by the drive roller through the idler gears.
