Abstract

L'invention concerne une pompe à vide à compression sèche, en particulier une pompe à vis, comprenant deux éléments de rotor (14) placés dans une chambre d'aspiration (12) et portés chacun par un arbre de rotor (22) respectif. Deux bouts d'arbre des arbres de rotor (22) font saillie à travers une paroi latérale (28) du corps de pompe (10). Une poulie crantée (38) est disposée sur chacun des deux bouts d'arbre (28). Ladite pompe comporte également un dispositif d'entraînement ainsi qu'un moteur électrique pour l'entraînement de l'arbre de rotor (22). Selon l'invention, l'entraînement des arbres de rotor (22) s'effectue par l'intermédiaire d'une courroie crantée (40). Pour permettre de recourir à une courroie crantée afin d'assurer l'entraînement, un jeu primitif entre les deux éléments de rotor (14) est supérieur à ± 0,75, en particulier supérieur à ±1°.
