摘要： A rotor comprises a central body configured to rotate. A lobe extends perpendicularly from the central body along an lobe axis. A curved leading periphery and a curved trailing periphery are on opposite sides of the lobe axis. A V-shaped rib spans between the curved leading periphery and the curved trailing periphery. A first hollow space is bounded by the V-shaped rib, the curved leading periphery, and the curved trailing periphery. The first hollow space is distal with respect to the central body along the lobe axis. A second hollow space is bounded by the V-shaped rib, the central body, the curved leading periphery, and the curved trailing periphery. The second hollow space is proximal with respect to the central body along the lobe axis. The rotor can comprise a plurality of stacked, stamped sheets to form a helically twisted supercharger rotor.
