摘要： A hydrodynamic bearing device comprises a shaft bush having a substantially conical inclined dynamic pressure surface around the outer circumference thereof which is relatively rotatably inserted in a bearing sleeve having a substantially conical inclined dynamic pressure surface around the inner circumference thereof. A substantially conical inclined bearing space is created in the gap between the inclined dynamic pressure surfaces of the bearing sleeve and shaft bush. Lubricant fluid is filled inside the inclined bearing space. A proper dynamic pressure generating means is formed on at least one of the inclined dynamic pressure surfaces of the shaft bush and bearing sleeve. The lubricant fluid is pressurized by the dynamic pressure generating means to generate dynamic pressure, by which the shaft bush and the bearing sleeve are relatively elevated in the radial and thrust directions so that their rotations are supported in a non-contact manner. A fluid sealing portion is provided in the inclined bearing space to prevent the lubricant fluid from leaking outside of the inclined bearing space. A fluid pressurizing means is provided between the inclined bearing space and the fluid sealing portion to pressurize the lubricant fluid in the direction to push it toward the inside of the inclined bearing space.

摘要： A hydrodynamic bearing apparatus comprises a shaft and a bearing having facing hydrodynamic surfaces therebetween. Hydrodynamic pressure generating grooves are disposed on at least one of the facing hydrodynamic surfaces of the shaft and bearing. The apparatus relatively rotatably supports the shaft and bearing by the hydrodynamic pressure from a lubricant fluid filled between the facing hydrodynamic surfaces. One of the shaft and bearing, on which the hydrodynamic pressure generating grooves are formed, are made of a metallic material whose thermal expansion coefficient is smaller than that of a copper containing material. A working layer made of the copper containing material is formed on the hydrodynamic surface side of the metallic material. The surface of the working layer functions as the hydrodynamic surface. The hydrodynamic pressure generating grooves are formed on the working layer.
