Abstract: A mechanical mount axially and radially secures a device, such as a fan, to a shaft of a motor without a need for setscrews or keyways. Elimination of a keyway and setscrew for securing a fan to a motor shaft minimizes stress that the fan is subjected to during its operation. Certain exemplary embodiments of a system of the present invention comprising: a device; a mount of hardened material having a insertion edge with a concave shape secured to the device; and a shaft including an axial groove having a concave shape and a radial groove, wherein the mount along the insertion edge is insertable within the axial and radial groove, the concave shape of the insertion edge of the mount and the concave shape of the axial groove promoting a secure fit between the shaft and the mount to prevent axial and radial movement of the device.

Abstract: Certain exemplary embodiments provide a rotating machine assembly comprising a rotor machine assembly including a shaft, a plurality of laminations shrink fit around the circumference of the shaft, and weights affixed therebetween the laminations for balancing the rotating machine assembly.
