Abstract
Broche de palier à air, comprenant : un corps de machine (1) comportant un trou d'arbre, une partie centrale d'arbre (2), un ensemble moteur (7) utilisé pour entraîner la partie centrale d'arbre (2) en rotation, un palier à air (3), un palier de butée (4) et un canal d'admission (6). La partie centrale d'arbre (2) est agencée pénétrante dans le trou d'arbre et est pourvue d'un disque volant de butée (21) ; le palier à air (3) est disposé dans le trou d'arbre et correspond à la surface de palier de cercle extérieur de la partie centrale d'arbre (2) ; le palier de butée (4) comprend un palier de butée avant (41) et un palier de butée arrière (42), qui correspondent respectivement aux surfaces avant et arrière du disque volant de butée (21) ; le canal d'admission (6) comprend un canal d'admission principal (61), un premier canal d'admission de dérivation (62) et un second canal d'admission de dérivation (63), les premier et second canaux d'admission de dérivation (62, 63) étant respectivement reliés aux paliers de butée avant et arrière (41, 42), et les ouvertures des premier et second canaux d'admission de dérivation (62, 63) étant de 0,8 à 1,0 mm. La broche de palier à air peut empêcher efficacement le palier de butée de générer une vibration d'air, ce qui permet d'améliorer considérablement la rigidité et la précision de rotation dynamique de la broche. L'invention concerne également une machine-outil de meulage comprenant la broche de palier à air.
