摘要： A rotor for a multi-stage vacuum pump, a multi-stage vacuum pump and a method are disclosed. The rotor comprises: a plurality of rotary vanes, the plurality of rotary vanes being axially displaced and coaxially aligned; a pair of end shafts, each end shaft extending from opposing axial ends of the plurality of rotary vanes; and an inter-vane shaft extending between adjacent rotary vanes of the plurality of rotary vanes, the inter-vane shaft having a diameter which is greater than that of the end shafts. In this way, the inter-vane shaft provided between each rotary vane may have an increased diameter, which improves the stiffness of the shaft and changes the modal frequency of the rotor. Such a change in the modal frequency is typically sufficient to improve its operation.

摘要： Described is a lobe rotor (1) comprising a first (2) and a second (3) section defining the respective ends of the rotor (1), spaced apart from each other along a longitudinal axis (X) of extension of the rotor; each first (2) and second (3) section having the same profile comprising at least two lobes (4, 5) extending radially, with respect to a hub (1a) through which the central axis (X) the rotor passes and whose extension defines respective vertices and corresponding grooves (G4, G5) of the rotor (1); the first (2) and second (3) section being positioned relative to each other with their respective profiles coinciding along the axis (X) the rotor; a third central section (6) interposed between the first (2) and the second section (3), along the axis (X) the rotor, and having the same profile as the first (2) and second (3) end section, that is to say, comprising at least two lobes (4, 5) with a radial extension whose extension defines respective vertices and corresponding grooves (G4, G5); the third section (6) is rotated about the axis (X) of the rotor, with respect to the first (2) and second (3) cross section in such a way as to offset by an angle (α) the respective vertices and grooves (G4, G5) of the at least two lobes (4, 5) with respect to the vertices and grooves (G4, G5) of the lobes (4, 5) of the first (2) and second (3) section; a first (7) and a second (8) joining body between the first (2) and the second (3) end section and the third central section (6); each first (7) and second (8) joining body having inclined connecting surfaces, along the axis (X) of the rotor, for connecting the respective vertices and grooves (G4, G5) of the at least two lobes (4, 5) of the first (2), second (3) and third (6) section so as to form at least two grooves (G4, G5) opposite each, other along the axis (X) of the rotor, with undulating extension and each formed at least by the central surface (9) of the third central section (6) having the edges parallel to the axis (X) the rotor and by two surfaces (10, 11) formed respectively by the first (7) and second (8) joining body and having the edges inclined and converging towards the central surface (9).
