Abstract
A drill bit is provided that includes a bit body having one or more blades extending therefrom, a plurality of cutters secured to the one or more blades, and a rolling element assembly positioned within a cavity defined on the bit body. The rolling element assembly includes a rolling element rotatable within the cavity about a rotational axis, and a compliant retainer extendable within a retainer slot defined in the cavity to secure the rolling element within the cavity. The compliant retainer and the cavity cooperatively encircle more than 180° but less than 360° of a circumference of the rolling element while leaving a full axial width of the rolling element exposed. The compliant retainer is compressible responsive to forces from the rolling element to absorb vibrations and/or automatically adjust depth of cut.
