Abstract[English]
Provided is a structure for mitigating an impact in a radial direction of a flange axis when an impact is applied to a flange. A vacuum pump includes: a casing having an inlet port flange with a bolt hole formed therein; a rotor shaft disposed within the casing; and a rotor blade that is able to rotate together with the rotor shaft; wherein the inlet port flange includes a recessed portion that is formed continuously adjacent to the bolt hole in a radial direction of the rotor shaft and has a depth smaller than a thickness of the inlet port flange to leave a first thin portion, and a through hole formed adjacent to the bolt hole in a direction opposite to a rotational direction of the rotor shaft with a second thin portion interposed therebetween.[French]
Est proposée une structure pour atténuer un impact dans un sens radial d'un axe de bride lorsqu'un impact est appliqué à une bride. Une pompe à vide comprend : un boîtier comportant une bride d'orifice d'entrée avec un trou de boulon formé à l'intérieur de celui-ci ; un arbre de rotor disposé à l'intérieur du boîtier ; et une pale de rotor qui peut tourner conjointement avec l'arbre de rotor ; la bride d'orifice d'entrée comprenant une partie évidée qui est formée en continu adjacente au trou de boulon dans un sens radial de l'arbre de rotor et présente une profondeur inférieure à une épaisseur de la bride d'orifice d'entrée pour laisser une première partie mince, et un trou traversant formé adjacent au trou de boulon dans un sens opposé à un sens de rotation de l'arbre de rotor avec une seconde partie mince interposée entre ceux-ci.
