Abstract:
A mud motor bearing assembly for use in drilling a hydrocarbon well. The bearing assembly includes a bearing section containing stationary bearing rigs and rotating bearing rings in stacked arrangement. The bearing rings have wedge-shaped projections. The wedge-shaped projections of two adjacent stationary bearing rings form a recess to accommodate the projection of a rotating bearing ring in sliding engagement. The bearing assembly is capable of bearing both radial and axial loads.
