Abstract

In a mechanically driven supercharger (1) whose rotor (6) is propelled by an internal combustion engine by way of a primary shaft (2), a planet gear (8) that is geared up and a rotor shaft (7), the working life of a support (11, 12) for the rotor shaft (7) is increased. For that purpose, the support floats with radial play (17) and axial play (19) in a fixed housing section (10) of the supercharger (1).
