摘要： A hydrodynamic bearing having a high performance and a long life and a manufacturing method for the same are provided by forming hydrodynamic grooves to have a sufficient depth with a high accuracy, and sealing remaining pores on a bearing surface. A shaft is inserted into a bearing hole of a sleeve so as to be relatively rotatable. The bearing hole has a bearing surface having hydrodynamic grooves. The sleeve is formed by: forming metal powder to have a hollow cylindrical shape, sintering the metal powder; inserting a core rod in a pattern having a tapered surface into a bore of the sintered metal material; forming an inner surface having hydrodynamic grooves by pressing the sintered metal material from upper, lower and outer peripheral direction; inserting a core rod having a wide diameter portion and a narrow diameter portion into the bore of the sintered metal material to form the bearing bore surface of a hydrodynamic groove with the small diameter portion and to form the sleeve inner surface with the wide diameter portion at the same time; and removing the core rod from bore of the sintered metal material to have the inner periphery formed as such as the bearing inner surface and a large diameter portion as a lubricating fluid reservoir. Thus, grooves can be processed with a high accuracy.

摘要： A reduction gear equipped with a wave generator nearly elliptical in shape, two circular splines with differing numbers of internal teeth, a flex spline which partially meshes with the internal teeth of each of the circular splines and which is deformable in the radial direction and a bearing deformable in the radial direction, which, placed between the wave generator and the flex spline, renders both members relatively slidable, with notches which permit partial deformation of the bearing (6) or the flex spline provided in the wave generator or circular splines at positions corresponding to the balls of the aforementioned bearing, whereby backlash is eliminated and its positive operation is assured.
