Abstract:
A gear having an axis of rotation includes a gear rim, with at least a portion of the gear rim configured to receive a load and define a loaded gear rim arc corresponding to the portion of the gear rim. A bearing pin extends axially through the gear rim, the gear rim and the bearing pin defining a roller element gap therebetween. The gear rim is configured to define a loaded roller element gap arc substantially concentric with the loaded gear rim arc, the loaded element gap arc having a loaded roller element gap arc length. The gear rim is further configured to retain a loaded bearing portion of the bearing within the portion of the roller element gap such that a loaded bearing portion length is in a range from and including about 75% to and including about 125% of the loaded roller element gap arc length.
