ABSTRACT:
A torque limiter for use on an aircraft comprises a drive shaft having a toothed outer portion, an output shaft, and a spline having an aperture therethrough for receiving the toothed portion. The spline is configured to rotationally couple the drive shaft to the output shaft and to rotationally disengage from the output shaft when the torque at the drive shaft exceeds a predetermined torque threshold. The spline comprises an outer annular portion and an inner annular portion configured to receive a lubricant. The inner annular portion comprises a plurality of circumferentially-spaced tooth structures and root structures. At least one of the root structures has at least one slot therein for receiving and retaining the lubricant.
