摘要： A housing has a vertically extending cylindrical bore, with a radical bearing surface formed on the inner peripheral surface, and a thrust bearing surface formed on the inner bottom surface of the cylindrical bore. A shaft member which is supported rotatably in the cylindrical bore of the housing has a radial receiving surface and a thrust receiving surface respectively formed on the outer peripheral surface and the bottom surface. A dynamic pressure generating groove of a spiral shape is formed in at least one of the radial bearing surface and ther radial receiving surface. When the shaft member is rotated, a gas in the housing is sucked by the pumping action of the dynamic pressure generating groove and flows into a pressure chamber between the thrust bearing surface and the thrust receiving surface through a radial space between the radial bearing surface and the radial receiving surface. The pressure in the pressure chamber maintains the shaft member in a floating position by a predetermined amount. The shaft member has a passage bore formed along a center axis line. The passage bore includes a restricted aperture of a smaller diameter which opens at the thrust receiving surface of the shaft member to thereby allow the gas in the pressure chamber to be exhausted into the housing through the passage bore.
摘要翻译：壳体具有竖直延伸的圆柱形孔，内圆周表面上形成有自由基轴承表面，以及形成在圆柱孔内底表面上的止推轴承表面。可旋转地支撑在壳体的圆筒孔中的轴构件具有分别形成在外周表面和底表面上的径向接收表面和止推接收表面。在径向轴承表面和径向接收表面中的至少一个中形成螺旋形状的动态压力产生槽。当轴构件旋转时，壳体中的气体通过动压产生槽的泵送作用被吸入，并通过径向支承表面和径向轴承表面之间的径向空间流入推力轴承表面和推力承受表面之间的压力室中径向接收面。压力室中的压力将轴构件保持在浮动位置预定量。轴构件具有沿着中心轴线形成的通道孔。通道孔包括较小直径的限制孔径，其在轴构件的推力接收表面处开口，从而允许压力室中的气体通过通道孔排出到壳体中。

摘要： A bearing with dynamic pressure grooves includes an outer cylinder made of a metal and a resin sheet bonded to the inner peripheral surface of the outer cylinder. The resin sheet is made of a thermoplastic resin, for example, a polytetra fluoroethylene, as a main component mixed with a wear-resistant improving material, for example, graphite or the like. The resin sheet is formed with a pattern of dynamic pressure generating grooves formed in an inner surface by plastic work. The pattern of grooves is varied depending on the types of relative movement between the outer cylinder and a shaft body, i.e., whether an axial linear movement, a rotational movement, or a spiral movement.

摘要： This invention relates to sealing and bearing means by use of ferrofluid, in which a magnet is utilized effectively in cooperation with grooves engraved on one surface thereof, the grooves having the function for generating the dynamic pressure of the ferrofluid. The ferrofluid is retained in a gap between a rotary shaft and a magnet of cylindrical or disc type enclosing the rotary shaft concentrically. The magnet performs excellent two functions of bearing and sealing respectively.

摘要： In an assembly of linear feeding means in which a carrying or carriage member is supported on a rod shaped supporting member and these two members can be relatively moved in lengthwise direction, a plurality of recesses each having a shape or arrow head are disposed such that the tip end of each of the arrow head type recesses is directed to either one direction or to the other opposite direction of the relative movement of the assembly.By virtue of this construction, hydrodynamic pressures are directed in both directions as to ensure smooth running of the assembly.
