Abstract

PURPOSE: To reduce the fluctuation of an electron beam collision surface in a rotary anode type X-ray tube by providing means for varying a spring for imparting preliminary pressure to a ball bearing in thrust direction and the preliminary pressure in a stator thereof to thereby enable use with low preliminary pressure after imparting sufficient preliminary pressure to machine a specimen.
CONSTITUTION: A spring 19 for imparting preliminary pressure to ball bearings 10, 11 in thrust direction is provided in the cylindrical stator 12 of a rotary anode, and means 16-18 for varying the preliminary pressure are provided therein. A movable stopper 16 having tapered surface is arranged between the spring 19 for imparting the preliminary pressure to the bearings 10, 11 to space predetermined interval, for examble, via the cylindrical spacer 13 at the outer periphery of the rotary shaft 9 and the bottom of the stator to vary the preliminary pressure in the range from 10 to 100kg by adjusting screws 17, 18. After sufficient preliminary pressure is applied to the bearings 10, 11 thus to grind the electron collision surface, the bearings can be used under low preliminary pressure without damage to thereby reduce the fluctuation of the electron collision surface in the X-ray tube.
