Concentrated high-speed rigid hub

A concentrated high-speed rigid hub (CHRH), the CHRH configured for coupling a coulter blade to an implement via a bearing, the CHRH having an inner hub rim within and concentric with an outer hub rim, each of the inner and outer hub rim concentric about an axis of rotation, an inner hub rim radius and an outer hub rim radius perpendicular to the axis of rotation, the inner hub rim associated with a bearing housing having a depth (d) parallel with the axis of rotation, the outer hub rim having a side wall depth parallel with the axis of rotation, the side wall depth substantially less than the bearing housing depth, the bearing housing configured to receive the bearing;

• the CHRH including at least four bosses, each one of the at least four bosses associated with a threaded aperture adapted for receiving a fastener, each boss of the at least four bosses configured for:
• 1) providing a thread depth associated the threaded aperture, the thread depth greater than the outer hub rim depth and less than the bearing housing depth, 2) transferring each of a radial load and an axial load between the outer hub rim to the inner hub rim, and 3) providing a structure surrounding the threaded aperture;
• the CHRH having a back side wall opposite, along the axis of rotation, from the at least four bosses, the back side wall having a ring surface area defined by a ring radius (γ) perpendicular to the axis of rotation, the ring surface area substantially planar enabling the back side wall contact with the coulter blade;
• the CHRH functions to 1) receive the fastener, as inserted through an associated coulter blade aperture and threaded within the threaded aperture of each of the at least four bosses, 2) couple the coulter blade to the CHRH via the back side wall, 3) secure the bearing within the bearing housing, and 4) couple the coulter blade to the implement via the bearing with no additional structure.
