Filed: 1982-01-18
Abstract: PURPOSE:To reduce skewing in a cross roller bearing for a rotating wheel by interposing a spacer, one end surface of which is plane, the other end portion thereof being a concave curved surface a little larger than the radius of curvature of a roller between adjacent rollers. CONSTITUTION:In a cross roller bearing for a rotating wheel, rollers 13 are kept away from each other by spacers 17.

The thickness (a) of the leading end circle of the concave curved surface 172 on the large side (bearing inward side) is smaller than the thickness (b) of the trailing end circle thereof on the small side (bearing outward side). Therefore, each roller is always rotated on its own axis which is the same central point, and the differential slide of each roller is uniformalized so as to maintain  a stable movement and prevent the roller from falling.

Abstract: PROBLEM TO BE SOLVED: To attenuate and absorb the rotating energy when a rotator is broken during high-speed rotation to prevent the secondary breakage by fixing, to the circumference of a support cylinder for supporting the rotor of a turbo- molecular pump, an annular stopper ring opposed to the lower inner side of a screw groove pump stage through a minute clearance. SOLUTION: When this turbo-molecular pump is operated, a current is carried to each of magnetic bearings 9-11 to lay a rotating shaft 7 and a rotor 6 into the floated state, and a motor 12 is driven to rotate the rotor 6 at high speed. At this time, a first stage compression is performed between a rotor blade 5 and a stationary blade 4 through a gas intake port 2, and a second stage compression is performed in a screw groove pump stage 8 to exhaust air through an exhaust port 3. Even if the rotor 6 is broken due to excessive vibration or internal abnormality occurrence at this time, the scattering of broken pieces of the rotor 6 can be suppressed since the center part of the rotor 6 is firmly fixed to the rotating shaft 7 by an upper stopper 31, and the lower end of the screw groom pump stage 8 is collided to a stopper ring 33 to absorb the kinetic energy of the rotor 6.
