Abstract

L'invention concerne une machine-outil (1) comprenant : un carter (10) ; un moteur (20), en particulier un moteur électrique ; un arbre d'entraînement (22) dont le fonctionnement est assuré par le moteur (20) ; un entraînement par courroie (50) servant à transmettre la force d'entraînement du moteur (20) sur un outil ; et un premier ventilateur (30) servant à produire dans le carter (10) un trajet d'air (70) qui sert à refroidir au moins le moteur (20). Le fonctionnement du premier ventilateur (30) et de l'entraînement par courroie (50) est assuré par l'arbre d'entraînement (22). La machine-outil (1) comprend un second ventilateur (40) servant à produire dans le carter (10) un second trajet d'air (80) qui sert à refroidir au moins l'entraînement par courroie (50).
