Title (EN) ROTOR AND ROTATING ELECTRIC MACHINE WITH THE ROTOR
(FR) ROTOR ET MACHINE ÉLECTRIQUE ROTATIVE DOTÉE DE CELUI-CI
(JA) 回転子およびこの回転子を備えた回転電機
Abstract: front page image
(EN)A motor has a rotating shaft (58) having a key groove (58a) formed in it, a through-hole (20a) capable of receiving the rotating shaft (58), a rotor core formed on the inner surface defining the through-hole (20a) and having a key section (42) fittable in the key groove (58a), and stress relaxation grooves (40, 140) depressed from the peripheral surface of the rotating shaft (58) and formed at those portions of the inner surface, defining the through-hole (20a), of the rotor core which are adjacent to the key section (42). The inner surface of the through-hole (20a) is formed in a circular arc shape. Of the inner surfaces of the stress relaxation grooves (40, 140), bottom surfaces (R1, R11) which are radially outer portions of the grooves (40, 140) have circular arc portions with the center (101) defining the through-hole (20a) as the center.
(FR)Moteur comportant un arbre rotatif (58) pourvu d'une rainure (58a) de clavette, un trou traversant (20a) conçu pour recevoir l'arbre rotatif (58), un noyau rotorique formé sur la surface intérieure définissant le trou traversant (20a) et comportant une partie de clavette (42) susceptible de se loger dans la rainure (58a) de clavette, et des cannelures (40, 140) de relaxation des contraintes ménagées en retrait de la surface périphérique de l'arbre rotatif (58) au niveau des parties de la surface intérieure définissant le trou traversant (20a) du noyau statorique qui occupent une position adjacente à la partie de clavette (42). La surface intérieure du trou traversant (20a) prend la forme d'un arc de cercle. Les surfaces de fond (R1, R11) des surfaces intérieures des cannelures (40, 140) de relaxation des contraintes forment des parties orientées radialement vers l'extérieur desdites cannelures (40, 140) et présentent des parties en arc de cercle dont le centre (101) coïncide avec le centre du trou traversant (20a).
(JA)モータは、周面にキー溝(58a)が形成された回転シャフト(58)と、回転シャフト(58)を受け入れ可能な貫通孔(20a)と、貫通孔(20a)を規定する内表面に形成され、キー溝(58a)に嵌合可能なキー部(42)とを有するロータコアと、貫通孔(20a)を規定するロータコアの内表面のうち、キー部(42)と隣り合う位置に形成され、回転シャフト(58)の周面から離れるように凹まされた応力緩和溝(40、140)とを備え、貫通孔(20a)の内表面は円弧状に形成され、応力緩和溝(40、140)の内表面のうち、径方向外方に位置する応力緩和溝(40、140)の底面(R1,R11)は、貫通孔(20a)を規定する中心(101)を中心とする円弧部を有する。
