ABSTRACT:
A conjugate gear system including a pair of meshingly engageable toothed gears, at least one member of the gear pair having at least one three-component tooth. Each three-component tooth is comprised of a central core, at least one face disposed thereon, and a means for displaceably attaching the face section to the core such that the face section is displaceable with respect to the core in the direction of the sliding component of motion created by meshing engagement of the gear pair. By separating out the sliding component in this fashion, relatively pure rolling contact is maintained between the engaged surfaces of the gear pair at all times, thus reducing sliding friction, thermal expansion, and noise levels created by the engagement of the gears.
