Title (EN) COMPRESSOR
(FR) COMPRESSEUR
(JA) 圧縮機
Abstract:
(EN) A compressor that: compresses refrigerant including a hydrofluorocarbon having the characteristic of causing disproportionation reactions; and has provided therein an elastic bearing (2) as a heat-generation suppression unit (1) that suppresses excessive heat generation resulting from linear contact between an edge of a bearing (B) and a drive shaft (S) during rotation of the drive shaft (S), same being provided in a contact section between the drive shaft (S) and the bearing (B).
(FR) L'invention concerne un compresseur qui comprime un fluide frigorigène comprenant un hydrofluorocarbure ayant la caractéristique de provoquer des réactions de dismutation, et qui comporte un palier élastique (2) en tant qu'unité de suppression (1) de génération de chaleur qui supprime une génération de chaleur excessive résultant d'un contact linéaire entre un bord d'un palier (B) et un arbre d'entraînement (S) pendant une rotation de l'arbre d'entraînement (S), celui-ci étant placé dans une section de contact entre l'arbre d'entraînement (S) et le palier (B).
(JA) 不均化反応を起こす性質を有するフッ化炭化水素を含む冷媒を圧縮する圧縮機において、駆動軸(S)と軸受部(B)との接触部に、駆動軸(S)の回転中に軸受部(B)の端縁が駆動軸(S)と線接触することで過度に発熱するのを抑制する発熱抑制部(1)として弾性軸受部(2)を設ける。
