SHAFT FOR DYNAMIC BEARING, DYNAMIC BEARING, AND METHOD FOR PRODUCING THE SHAFT

In a method for producing a shaft (2) for a dynamic bearing, relative vibration between a bar-like material (5) that is to be processed to the shaft (2) for a dynamic bearing and a grinding stone (processing tool)(11) for processing an outer peripheral surface (5a) of the material (5) is controlled....

Summary:In a method for producing a shaft (2) for a dynamic bearing, relative vibration between a bar-like material (5) that is to be processed to the shaft (2) for a dynamic bearing and a grinding stone (processing tool)(11) for processing an outer peripheral surface (5a) of the material (5) is controlled. This causes grooves (2b) to be arranged side by side in a circumferential direction of the outer peripheral surface (5a). In the shaft (2), the grooves (2b) and outer peripheral surfaces (2a) have uniform surface roughness, and the processed patterns are aligned in the circumferential direction. L'invention concerne un procédé de production d'un arbre (2) pour un palier dynamique, procédé comportant une étape consistant à contrôler la vibration relative entre un matériau du type barre (5), qui doit être usiné pour former l'arbre (2) pour le palier dynamique, et une pierre rectifieuse (outil d'usinage) (11) destinée à l'usinage de la surface périphérique (5a) du matériau (5). Le processus d'usinage entraîne la formation de rainures (2b) disposées côte à côte dans une direction circonférentielle de la surface périphérique externe (5a). Dans l'arbre (2), les rainures (2b) et les surfaces périphériques externes (2a) ont une rugosité en surface uniforme, et les modèles usinés sont alignés dans la direction circonférentielle.
