Abstract: A driven gear includes a radially outwardly extending flange. The radially outwardly extending flange extends along an axial distance defined along a center axis of the flange. The flange merges into a generally conical portion which, in turn, extends radially inwardly to a hub. The hub extends to a remote end. A first distance defined between the remote end of the hub and an end of the flange faces the remote end. A second distance is defined between ends of the flange, with gear teeth formed at an outer periphery. A ratio of the first distance to the second distance is between 2.54 and 2.82. An oil pump, a rotating portion for an electrical generator, and a generator are also disclosed.

Abstract: A generator includes a main cavity and a shaft located in the main cavity. The shaft is configured to be connected to an auxiliary power unit (APU) and rotated by the APU. The generator is configured to generate power based on the rotation of the shaft. A fluid system is configured to receive a fluid from the APU, flow the fluid through the main cavity and return the fluid to the APU through a fluid scavenge channel. A filter is configured to filter the fluid from the main cavity to the fluid scavenge channel and a sensor is configured to detect a characteristic of the fluid at the filter.
