    摘要: A bearing (100) has a contact surface (110) for mating with a rotatable member. The contact surface has a plurality of crystalline grains (120) distributed at random; a plurality of micro-grooves (130) are formed among the crystalline grains; the micro-grooves communicate with each other thereby forming a net. The micro-grooves accommodate lubricant therein so that when the rotatable member rotates, a sufficient lubrication can be obtained between the bearing and the rotatable member. The bearing is formed by machining and then thermally etching a preform which is formed by powder metallurgy.

    摘要: Disclosed herein is a method of manufacturing a hydrodynamic bearing in which a metal bearing made of sintered metal powder is internally subjected to chemical etching, to form hydrodynamic pressure grooves thereon, thus assuring a high-precision and reliable hydrodynamic bearing. The method includes: compressing metal powder that is a raw material of the bearing in a press unit, and sintering the compressed metal powder at a predetermined temperature, thus preparing a sintered bearing; removing foreign substances adhering to the sintered bearing through a deburring process, and pressing the sintered bearing into a desired shape; forming a hydrodynamic groove, configured to generate hydrodynamic pressure, on an internal surface of the shaped bearing using chemical etching; and conducting a post treatment of cleaning the bearing including the hydrodynamic grooves thereon and drying the bearing.

    摘要: A plate-like material is pressed and a middle concave portion centered on a center axis is formed in one axial surface of the material. Likely, an annular concave portion centered on a center axis and radially outwardly arranged is formed in one and/or the other axial surface of the material. The material is then cut along a radially outer rim of the middle concave portion, and between a radially outer rim and a radially inner rim of the annular concave portion. In this way, a thrust plate having indented portions at radially inside and outside portion of the one and/or the other axial surface thereof is manufactured. A burr formed in press working is accommodate within the indented portion and does not axially protrude from the one and/or the other axial surface of the thrust plate.
