GEARS HAVING REDUCED ROLLER ELEMENT STRESS

A gear (204) having an axis of rotation includes a gear rim (306), with at least a portion (372) of the gear rim (306) configured to receive a load and define a loaded gear rim arc (376) corresponding to the portion of the gear rim (306). A bearing pin (302) extends axially through the gear rim (306...

More Information
Summary:A gear (204) having an axis of rotation includes a gear rim (306), with at least a portion (372) of the gear rim (306) configured to receive a load and define a loaded gear rim arc (376) corresponding to the portion of the gear rim (306). A bearing pin (302) extends axially through the gear rim (306), the gear rim (306) and the bearing pin (302) defining a roller element gap (313) therebetween. The gear rim (306) is configured to define a loaded roller element gap arc (378) substantially concentric with the loaded gear rim arc (376), the loaded element gap arc (378) having a loaded roller element gap arc length (358). The gear rim (306) is further configured to retain a loaded bearing portion (307) of the bearing (303) within the portion of the roller element gap (313) such that a loaded bearing portion (307) length is in a range from and including about 75% to and including about 125% of the loaded roller element gap arc (378) length.
