Abstract
A quiet-running, multi-layer gear assembly includes a stiff center member sandwiched between a pair of outer members. At least one of the outer members is compliant; preferably, both are. The stiff center member has an outer peripheral surface with gear teeth. Each of the outer members has an outer peripheral surface with gear teeth disposed in a respective directed axial thrust pattern. The center and outer members are joined on a central hub with their outer peripheral surfaces aligned so as to form a gear assembly.
