摘要： In a grease filled bearing for a machine such as a turbo molecular pump that rotates at high speed, objects are to prevent grease retained in an inner circumferential part of a ball retainer from being forced out to the outside of the bearing due to centrifugal force, thereby achieving extension of the operational life of the bearing, and preventing occurrence of rotational mass unbalance due to the grease forced out. A retainer (1) of a ball bearing includes a main body (1A) having a circular annular shape, and plural circular pockets (1a) for retaining balls (4) therein that extend through the main body (1A) in a radial direction, wherein intermediate parts between adjacent pockets (1a) in an inner circumferential surface of the main body (1A) define recesses (1b) for holding grease.

摘要： A thread groove type vacuum pump in which the gap between a rotor and a stator is not subjected to any influence of the rotor temperature and thus the pumping performance does not deteriorate during plasma combustion in a nuclear fusion reactor. The thread groove pumping portion is formed as a circular cone so that the expansion and contraction of the rotor occurs along the generatrix of the circular cone. The pump exhibits supreme pumping performance throughout the whole running mode of the vacuum pumping system of the nuclear fusion reactor because the gap between the rotor and the stator is kept constant despite changes of thermal expansion due to the temperature change of the rotor caused by the different gas loads.

摘要： Disclosed is a vacuum pump having a peripheral groove vacuum pump unit which includes a casing provided with an inlet port and an outlet port; a rotor disposed within the casing and including a rotor shaft journaled on the casing, a rotor body fixed to the rotor shaft and provided integrally with a rotor disk; and a stator fixedly disposed within the casing and provided with an annular groove receiving the peripheral portion of the rotor disk. Both sides of the peripheral portion of the rotor disk are cut in steps or portions of the side walls of the annular groove corresponding to the peripheral portion of the rotor disk to form flow passages on both sides of the peripheral portion of the rotor disk. Partitions are projected from the stator into the flow passages. The starting ends of the flow passages on the inlet side of the partitions communicate with the inlet port, and the terminating ends of the same on the outlet side of the partitions communicate with the outlet port. The vacuum pump is capable of operating at a high pumping speed. Spaces between the peripheral portion of the rotor disk and the inner surfaces of the annular groove of the stator need not be sealed and large clearances may be formed therebetween, so that the components of the vacuum pump can easily be machined without requiring high machining accuracies. The vacuum pump can be formed with a compact construction. Solid particles sucked into the vacuum pump together with the gas or those produced by chemical reaction resulting from compression can be discharged outside and the vacuum pump is able to operate without problems occurring even if solid particles are contained in the gas.
