Title (EN) A ROTOR UNIT AND A METHOD FOR ITS BALANCING
(FR) UNITE ROTOR ET PROCEDE D'EQUILIBRAGE CORRESPONDANT
Abstract: front page image
(EN)A gas turbine unit (20) has a rotor unit (10) comprising a mono-shaft (30), a compressor wheel (40), a turbine wheel (50), a tie bolt (60), and a tie bolt nut (70). The mono-shaft (30) is essentially cylinder-shaped with a centre through hole for containing the tie bolt (60), and has a first supporting bearing arrangement (100) detachably attached to a first end and a second supporting bearing arrangement (110) detachably attached to a second end. The compressor wheel (40) and the turbine wheel (50) constitute a detachable unit, which is attached by means of the tie bolt (60) at the second end of the mono-shaft (30), forming a shaft overhang, the tie bolt protruding through the centre of the mono-shaft and into the centre of the turbine wheel.
(FR)L'invention concerne un ensemble turbine à gaz (20) dont l'unité rotor (10) comprend un mono-arbre (30), une roue (40) de compresseur, une roue (50) de turbine, un boulon (60) d'assemblage et un écrou (70) de boulon d'assemblage. Le mono-arbre (30), qui est de forme sensiblement cylindrique, est percé d'un trou traversant central destiné au logement du boulon (60) d'assemblage. Il comporte, en outre, un premier dispositif porteur (100) d'appui fixé libérable à une première extrémité et un second dispositif porteur (110) d'appui fixé libérable à une seconde extrémité. La roue (40) de compresseur et la roue (50) de turbine constituent un module amovible, qui est fixé à la seconde extrémité de l'arbre (30) au moyen du boulon (60) d'assemblage, formant ainsi un porte-à-faux du fait que le boulon d'assemblage dépasse au niveau du centre de l'arbre et rentre dans le centre de la roue de turbine.
