  • Patent number: 10323465
    Abstract: A drill bit includes a bit body having cutters and a generally cylindrical rolling element secured thereon. The rolling element protrudes from the bit body to engage a geologic formation. The location and orientation of the rolling element may be selected such that an outer surface of the rolling element maintains multiple points of contact with the geologic formation to balance the operational forces acting thereon for a desired minimum depth of cut. A moment acting on the rolling element may be minimized to thereby prevent damage to the drill bit. A method for configuring the rolling element may include calculating a critical depth of cut for each point along a radial interval defined by the cylindrical body, changing a design variable, and recalculating the critical depth of cut until at least three contact points exist along the rolling element for a desired minimum depth of cut for the interval.
