Abstract

Procédé de fabrication d'une aube coulissante d'un compresseur consistant à sélectionner un matériau de base approprié de l'aube coulissante du compresseur et à réaliser une coupe, un traitement thermique, un ébavurage, une nitrification, un broyage et une mouture fins sur le matériau de base afin d'obtenir une aube coulissante qualifiée. Une rainure pour aiguille de roulement destinée à la mise en place d'aiguilles de roulement est obtenue par les étapes suivantes : 1) perçage : percer un trou ayant un diamètre légèrement inférieur à celui d'une aiguille de roulement sur un côté du matériau de base de l'aube coulissante ; 2) alésage : aléser le trou percé ; 3) pierrage : effectuer un pierrage dans le trou alésé de sorte que la surface du trou atteigne une précision spécifiée ; et 4) coupe : couper selon une ligne de coupe sur le matériau de base pierré de l'aube coulissante, et découper une partie supérieure du trou dans l'aube coulissante pour obtenir l'aube coulissante du compresseur avec une rainure pour aiguille de roulement. À l'aide procédé, le trou après traitement a une précision élevée et une aube coulissante de précision élevée est obtenue ; et les aiguilles de roulement sont limitées par un côté en forme d'arc de la rainure de manière à ne pas tomber de l'ouverture dans la partie supérieure d'une ouverture de rainure, et par conséquent, une partie de limitation n'a pas besoin d'être agencée sur un côté latéral d'une rainure d'aube coulissante.
