The method for manufacturing fluid power transmissions sequentially performs: a first process of assembling a provisional blade-core assembly (38) obtained from connecting multiple blades (2b) to a core (2c) so as to move freely by lining up the multiple blades (2b) on a blade alignment jig (J1) and superposing the core (2c) above the group of blades (2b) while loosely inserting protruding pieces (30) provided on each blade (2b) in engaging holes (31) provided on the core (2c) and then bending the tips of the protruding pieces (30) so as to keep the protruding pieces (30) from slipping out of the engaging holes (31); a second process of setting the provisional blade-core assembly (38) at a prescribed position on the inner surface of a shell (2s); and a third process of soldering the protruding pieces (30) to the engaging holes (31) and the blades (2b) to the shell (2S), respectively. As a result, ease of assembly is favorable and it is possible to bond the three parts, the shell, the blades and the core, without strain and obtain a high quality impeller for a fluid power transmission. Se proporciona un método para fabricar una transmisión de energía por fluido en donde el método incluye en secuencia un primer paso de ensamblar un ensamble provisional de cuchilla/núcleo (38) que tiene una pluralidad de cuchillas (2b) unidas de manera móvil a un núcleo (2c), que involucra alinear la pluralidad de cuchillas (2b) en un portapiezas de alineación de cuchilla (J1), colocar un núcleo (2c) sobre un grupo de cuchillas (2b) mientras que al mismo tiempo se extiende de manera holgada una pieza proyectada (30) provista en cada cuchilla (2b) a través de un orificio de cierre (31) provisto en el núcleo (2c) y doblar una parte de extremidad de la pieza proyectada (30) de manera que se evita que la pieza proyectada (30) salga del orificio de cierre (31), un segundo paso de ajustar el ensamble provisional de cuchilla/núcleo (38) en una posición predeterminada sobre una cara interior del armazón (2s), y un tercer paso de llevar a cabo un afianzamiento entre la pieza proyectada (30) y el orificio de cierre (31) y entre la cuchilla (2b) y el armazón (2s); de esta manera, la facilidad de ensamblado es buena, y es posible obtener un impulsor de alta calidad de una transmisión de energía por fluido al unir sin distorsión tres piezas, es decir, un armazón, una cuchilla y un núcleo.
