摘要： There is provided a rotating anode X-ray tube capable of efficiently discharging intense heat generated when X-rays are generated and achieving a high output power, a long-time continuous operation and a long operating life of the bearings. A rotating anode X-ray tube is provided with a target, a rotor, a shaft, rolling bearings and a bearing housing for supporting the rolling bearings. An accommodating, section for accommodating Ga or Ga alloy is defined by a center portion of the shaft and an inner surface of the bearing housing between the rolling bearings. Pumping grooves and labyrinth grooves are provided axially outwardly of the accommodating section for preventing the Ga or Ga alloy from leaking.

摘要： In a method of fabricating a variator disc, an outer periphery (5) of the input disc (D1), with a spline hole (4) thereof meshed with an input shaft (6), is finished using the input shaft (6) as a working reference. Subsequently, a race (2) is finished with high precisions using the outer periphery (5) as a working reference. There is an alternative method wherein a spline hole (4) with a machining allowance is precisely formed by means of a broach (X) prior to the heat treatment of a blank (B); after hardening the blank (B) by the heat treatment, tooth flanks (4a) of the spline hole (4) are precisely finished by means of a finishing broach (Y); and then, a race (2) of an input disc (D1) is precisely finished using the tooth flanks (4a) as a working reference.

摘要： A dynamic pressure bearing is provided in which leakage of liquid lubricant due to precession of a housing can be prevented from occurring. In the dynamic pressure bearing, the inner diameter of a tapered inner peripheral face 20 of the housing 1 which constitutes a capillary sealing portion 23 is gradually increased as moving from an opening 17 toward the inner area in the axial direction. When the housing 1 is rotated, therefore, a centrifugal force applied on liquid lubricant existing on the tapered inner peripheral face 20 acts in the direction along which the liquid lubricant is pushed toward the inner area, as indicated by an arrow 19. Consequently, the centrifugal force which is due to precession of the housing 1, and which pushes the liquid lubricant 15 toward the outside as indicated by an arrow 29 can be cancelled by the force acting in the direction toward the inner area, with the result that leakage of the liquid lubricant due to precession of the housing 1 can be prevented from occurring.
