FIELD: engines and pumps. ^ SUBSTANCE: proposed motor comprises stator (1) housing rotor packs (5) fitted on shaft (4). Moving bearing bushes (6) are arranged on both sides of packs (5). Note here that the rotor incorporates additionally the rings arranged on both sides of said moving bushes to change their radial size at axial loads. Note also that a part of end faces of aforesaid packs, rings and bushes, is made tapered for them to abut, while inner surface of at least of a part of rings, features cylindrical shape. Particularly, taper-inner-surface rings (7) are fitted between every pack (5) and moving bush (6) to adjoin mating surfaces of adjacent packs (5) and bushes (6). Outer rings (12) are arranged on rotor ends, end face surface of said ends being tapered on one side and cylindrical on the other to ensure required axial sizes. Rings (7) and (12) made with cutouts allow adjustment of their radial size under axial load. ^ EFFECT: longer life, reduced vibration, reduced operating clearances adding to ease of assembly. ^ 6 cl, 6 dwg |
