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： The oil-free chain is obtained by connecting a pair of inner link plates which are connected by oil-impregnated bushings and a pair of outer link plates, which are connected by pins inserted into adjacent oil-impregnated bushings of adjacent inner link plates alternately. The oil-impregnated bushing is obtained by impregnating a bushing made of a metal sintered body with perfluoropolyether having a kinematic viscosity at 40° C. equal to or higher than 350 mm2/s. The bushing is impregnated with perfluoropolyether having a kinematic viscosity corresponding to the operating temperature of the oil-free chain.

摘要： A lubricating-layer-equipped bearing enabling a reduction in the minimum bearing load required in the initial operation, and a method for easily forming a lubricating layer in the lubricating-layer-equipped bearing. The extension from an inscribed circle S in which rollers are inscribed to a minimum inner-periphery face lid of a retainer 11 is provided as a non-lubricating space without a lubricating layer G being provided. The lubricating layer is formed in the bearing by inserting the bearing having a retainer inserted in an outer ring, in a forming die 7; feeding a fluid-lubricant 9 including a thermoplastic resin into the forming die; reducing pressure in the forming die with the fluid lubricant fed to remove air bubbles from the fluid lubricant; pressing a cylindrical elastic solid 13 having an outer shape greater than the minimum inner-diameter S2 of the retainer, into an inscribed circle; and heating and setting the thermoplastic resin.
