Increased capacity spherical lined bearings

摘要

A rotary system (103) and method to control feathering movement of a rotor blade (201). The system having a yoke arm (205) configured to rotate a rotor blade. A first bearing (211) and a second bearing (213) are utilized to secure the rotor blade to the yoke arm (205) and are configured to restrict longitudinal and transverse movement, while allowing feathering movement of the rotor blade relative to yoke arm.
