Abstract:
1. An engine gear drive assembly comprising: a first taper gear rotationally and axially fixed to a first rotary engine component; a second taper gear rotationally fixed to a second rotary engine component and axially displaceable relative to the second rotary engine component, the second taper gear defining a bore receiving the second rotary engine component therein, the bore including an axial recess receiving a retaining ball fixed from axial travel along and rotation about the second rotary engine component to guide axial displacement of the second taper gear along the second rotary engine component and fix the second taper gear for rotation with the second rotary engine component, the retaining ball being rotatable in a fixed location relative to the second rotary engine component during axial displacement of the second taper gear; and a biasing member biasing the second taper gear in a first axial direction into engagement with the first taper gear and toward an engine structure supporting the first and second rotary engine components.
