Abstract (en)
[origin: EP2565464A2] The vacuum pump has a rotor (10), which has a shaft (12), a hub (40) connected with the shaft and a sleeve (50) that is concentric to the shaft and is connected with a side (42) of the hub. Another sleeve (52), which is concentric to the shaft on another side (44) of the hub lying in an axial direction against the former side, is connected with the latter side of the hub. The former sleeve is subsequently arranged in the gas flow of the latter sleeve. The sleeves are made of carbon fiber reinforced plastic.
