Title (EN) ROTARY MACHINE
(FR) MACHINE ROTATIVE
(JA) 回転機械
Abstract:
(EN) An electric compressor 1 that is provided with: a bearing 20B that supports a rotary shaft 12 of a compressor impeller 8; a support wall part 23 that supports the outer circumference of the bearing 20B; a key groove 60 that is formed in the bearing 20B and the support wall part 23 and extends along a rotary shaft line X direction of the rotary shaft 12; and a key member 70 that is inserted into the key groove 60. The support wall part 23 is provided with an outer regulating part 42a that can contact one end part 70a of the key member 70 inside the key groove 60. An outer ring 51 of the bearing 20B is provided with an inner regulating part 61a that can contact another end part 70b of the key member 70 inside the key groove 60. The distance D between the outer regulating part 42a and the inner regulating part 61a is longer than the length L of the key member 70 in the rotary shaft line X direction.
(FR) L'invention concerne un compresseur électrique (1) qui est pourvu : d'un palier (20B) qui porte un arbre rotatif (12) d'une roue de compresseur (8) ; d'une partie paroi de support (23) qui porte la circonférence externe du palier (20B) ; d'une rainure de clé (60) qui est formée dans le palier (20B) et la partie paroi de support (23) et qui s'étend dans la direction de la ligne d'arbre rotatif (X) de l'arbre rotatif (12) ; d'un élément de clé (70) qui est inséré dans la rainure de clé (60). La partie de support (23) est pourvue d'une partie de régulation externe (42a) qui peut entrer en contact avec une partie d'extrémité (70a) de l'élément de clé (70) à l'intérieur de la rainure de clé (60). Une bague externe (51) du palier (20B) est pourvue d'une partie de régulation interne (61a) qui peut entrer en contact avec une autre partie d'extrémité (70b) de l'élément de clé (70) à l'intérieur de la rainure de clé (60). La distance (D) entre la partie de régulation externe (42a) et la partie de régulation interne (61a) est plus longue que la longueur (L) de l'élément de clé (70) dans la direction de ligne d'arbre rotatif (X).
(JA) コンプレッサインペラ8の回転軸12を支持する軸受20Bと、軸受20Bの外周を支持する支持壁部23と、軸受20Bと支持壁部23とに形成され、回転軸12の回転軸線X方向に沿って延在するキー溝60と、キー溝60に挿入されるキー部材70と、を備え、支持壁部23は、キー溝60内でキー部材70の一方の端部70aに当接可能な外方規制部42aを備え、軸受20Bの外輪51は、キー溝60内でキー部材70の他方の端部70bに当接可能な内方規制部61aを備え、外方規制部42aと内方規制部61aとの距離Dは、キー部材70の回転軸線X方向の長さLよりも長い、電動コンプレッサ1である。
