摘要： An object of the present invention is to enhance the capacity of a turbomolecular pump.A turbomolecular pump is a composite-type vacuum pump that combines a blade portion and a thread groove portion. Openings are formed at a joint portion between a rotor blade holding portion that holds rotor blades and a stepped portion that holds a rotor cylinder portion, such that the openings span both the rotor blade holding portion and the stepped portion.Part of the gas that is evacuated by the blade portions is evacuated by a thread groove portion that is formed of the rotor cylinder portion and a stator thread groove, and the rest of the gas is led into the rotor cylinder portion via the openings, and is evacuated by a thread groove portion that is formed of the rotor cylinder portion and another stator thread groove. Stress derived from rotation of a rotor can be withstood when the openings are formed at the joint portion between the rotor blade holding portion and the stepped portion. Moreover, a groove in which a balancer weight is disposed is provided at a clearance portion that lies further on the inlet port side of the other stator thread groove, thereby eliminating the necessity of shortening the length of the other stator thread groove.

摘要： A turbo-molecular pump has a housing with intake and exhaust ports. A rotary body is enclosed in the housing and has rotor blades of a series of stages formed so that the outside diameter of at least one stage on the exhaust port side is smaller than that on the intake port side. Stator blades are arranged between the rotor blades and spacer rings are arranged between the stator blades to hold the stator blades at predetermined intervals. The spacer rings are formed so that the smallest inside diameter of at least one stage of the spacer rings on the exhaust port side is smaller than the largest outside diameter of the rotor blades. The housing comprises a casing whose inside diameter is constant or whose inside diameter is smaller at the intake port side than at the exhaust port side.

摘要： A flange of a molecular pump is connected to a vacuum vessel by first bolts that extend through elongate holes in the flange and are bolted to the vacuum vessel. One or more buffering members are attached to the flange by the first bolts that extend through first openings in the buffering members and by second bolts that extend through second openings in the buffering members and are bolted to the flange. In the event of malfunction of the molecular pump that generates an abnormally high torque, the buffering members plastically deform and absorb the shock energy caused by the abnormal torque thereby preventing damage to the vacuum vessel.
