A bearing mounting assembly for two counter rotating powered shafts, with an inner shaft concentric within a hollow outer shaft, has a sliding bearing as a collar thrust bearing. It is composed of an inner rotor (5) fixed to the inner shaft (1) and at least one carrier web (9-9"), and an outer rotor (6) bonded to the hollow shaft (2) and at least one carrier web (10-10"). The outer rotor (6) is bonded to the flanged (3, 4) hollow shaft (2) at the bearing zone. The intermeshing carrier webs (9-9"; 10-10"), in a comb structure, and the sliding surfaces are axially offset from each other, with a hydrostatic/hydrodynamic separation, to lie parallel to the axis of the inner shaft (1) or hollow shaft (2). The sliding surfaces of the carrier webs (9-9") of the inner rotor (5) are coated with copper, tin, or "Teflon" (RTM: polytetrafluoroethylene). The inner and outer rotors (5, 6) are of steel, or the inner rotor (5) is of solid bronze. |
