A vacuum pump, particularly a rotary vane pump with a high pumping capacity, has a pump chamber (12) in a housing (10). A pump element (14) is arranged in the pump chamber (12). The pump element (14) is supported by a rotor shaft (22). The rotor shaft (22) is connected to a belt pulley (24) arranged outside of the pump housing (10). The pump also has a motor (26) arranged outside of the pump housing (10). The drive shaft (28) of the motor (10) carries a drive pulley (30). The drive pulley (30) is connected to the rotor pulley (24) via a belt (32). To simplify assembly, the drive pulley (30) and/or the rotor pulley (24) are formed of multiple parts. |
