Title: Molecular turbo-pump
Inventor: KOYAMA TOMITAROU
IPC: F04D19/04
Filed: 1981-10-29
Abstract: PURPOSE:To enable to carry out gas exhausting operation with satisfactory function of lubricating oil, by providing an inert gas feeding means for feeding an inert gas gradually to a bearing section, and thereby avoiding contact of the bearing and a gas to be exhausted by the function of the inert gas. CONSTITUTION:A molecular turbo-pump of this invention comprises an inert gas feeding means 18 which feeds an inert gas little by little to a bearing section 4 for avoiding contact of the bearing 4 and the gas to be exhausted by the pump. In exhausting the gas existing on the side of a suction port 11 toward an exhaust port 12 successively by turning a rotor 7, contact of the gas to be exhausted with the bearing 4 is prevented by feeding the inert gas such as nitrogen or argon gas stored in a gas tank 19 of the means 18 little by little to the bearing section 4. With such an arrangement, it is enabled to prevent that the lubricating oil supplied to the bearing 4 is deteriorated by the gas to be exhausted or that the lubricating function of the oil is deteriorated by forming a powdery substance through reaction of the gas to be exhausted with the lubricating oil.

CONSTITUTION:In a cylindrical fixed bearing section 11 a rotary shaft section 12 having the shape of a bottomed-cylinder is put upside down in a rotatable state and a polygon mirror body 13 fitted to the upper end face 15 of the rotary shaft section. The lower end face 25 of the polygon mirror body 13 is closely faced to the upper end face 22 of the fixed bearing section 11 provided with spiral air grooves 23 for producing dynamic pressure at regular intervals. Thus a thrust dynamic pressure bearing is formed between the lower end face 25 of the polygon mirror body 13 and upper end face of the fixed bearing section 11. Since the bottom surface of the polygon mirror body 13 which becomes the reference plane for the perpendicularity of the reflecting faces is directly supported by the thrust dynamic pressure bearing, the perpendicularity of the polygon mirror body against the rotary shaft can be set with high accuracy and highly accurate optical scan can be performed.
