Abstract

A safelock system for removable gears is provided having a self-seating gear segment rotatably mounted on a helical ball spline for bi-directional axial movement with respect to the gear teeth to be locked. A relubrication structure is provided to service the interior of the ball spline. The interlocking teeth are two-dimensionally tapered from the point of initial engagement. Diverse biasing structures are employed to facilitate the axial self-seating reaction of the gear segment after initial engagement with the gear to be locked.
