Title (EN) METHOD FOR POLISHING BLADE TIP OF MOVING BLADES, AND JIG FOR POLISHING BLADE TIP OF BLISK
(FR) PROCÉDÉ DE POLISSAGE DE POINTE D'AUBE D'AUBES MOBILES, ET GABARIT DE POLISSAGE DE POINTE D'AUBE DE DISQUE MONOBLOC
(JA) 動翼の翼端研磨方法及びブリスクの翼端研磨用治具
Abstract:
(EN) When blade tips (11c, 13c, 15c, 17f) of moving blade rows (11, 13, 15, 17) are polished with grindstones (21, 23, 25, 27), a jig (30) is inserted into the moving blade rows (11, 13) of a blisk, and a jig (40) is inserted into the moving blade rows (13, 15). Blade engaging parts (33, 43) of the jigs (30, 40) engage respectively with the width-direction side parts of corresponding moving blades (11b, 13b, 13b, 15b) with a damping member (33a, 33b, 43a, 43b) made of rubber, etc., interposed therebetween. Disk engaging parts (31, 41) of the jigs (30, 40) are engaged to disks (11a, 13a, 13a, 15a) of the moving blade rows (11, 13, 13, 15) to which the blade engaging parts (33, 43) are respectively engaged.
(FR) Lorsque des pointes d'aube (11c, 13c, 15c, 17f) de rangées d'aubes mobiles (11, 13, 15, 17) sont polies à l'aide des meules (21, 23, 25, 27), un gabarit (30) est inséré dans les rangées d'aubes mobiles (11, 13) d'un disque monobloc, et un gabarit (40) est inséré dans les rangées d'aubes mobiles (13, 15). Des parties de prise d'aube (33, 43) des gabarits (30, 40) sont respectivement en prise avec les parties latérales dans la direction de largeur d'aubes mobiles correspondantes (11b, 13b, 13b, 15b), un élément d'amortissement (33a, 33b, 43a, 43b) en caoutchouc, etc., étant interposé entre elles. Des parties de prise de disque (31, 41) des gabarits (30, 40) sont en prise avec des disques (11a, 13a, 13a, 15a) des rangées d'aubes mobiles (11, 13, 13, 15) avec lesquelles les parties de prise d'aube (33, 43) sont respectivement en prise.
(JA) 動翼列(11,13,15,17)の翼端(11c,13c,15c,17f)を砥石(21、23、25、27)により研磨する際に、ブリスクの動翼列(11,13)の間に治具(30)を挿入し、動翼列(13,15)の間に治具(40)を挿入する。治具(30,40)の翼係止部(33,43)は、対応する動翼(11b,13b、13b,15b)の幅方向における側部に、ゴム等の緩衝部材(33a,33b、43a,43b)を介してそれぞれ係止する。治具(30,40)のディスク係止部(31,41)は、翼係止部(33,43)をそれぞれ係止した動翼列(11,13、13,15)のディスク(11a,13a、13a,15a)に係止する。
