Abstract

Dispositivo para el templado simultáneo periférico inductivo de superficies de rodadura (2A, 3A) y radios de transición en cigüeñales (1) con gorrones (2, 3) expuestos directamente uno junto a otro, y con diferentes posiciones angulares en el plano un perpendicular a su eje de rotación (D) directamente uno tras otro, habiéndose previsto por lo menos de forma aproximada en la misma dirección (C) en los gorrones (2, 3) inductores (8, 9), los cuales - cada uno de ellos corresponden a un gorrón (2, 3) y están colocados uno tras otro, cortando la dirección del eje del cigüeñal (1), así como por lo menos dos ramas inductoras dispuestas paralelas entre sí (8C, 8D, 9C, 9D) de las cuales en cada una está dispuesta una rama inductora (8D, 9D) en una zona cubierta (4) del gorrón (2, 3) y la otra rama inductora (8C, 9C) está dispuesta en una zona marginal del gorrón (2, 3) dirigida hacia una gualdera (5, 6), - cada uno de ellos está formado con una sección inductora larga (8A, 9A) y una sección inductora corta (8B, 9B) de tal manera que las secciones inductoras largas (8A, 9A) presentan parcialmente una anchura (b_1), que son mayores que la mitad de la anchura total (B) de la superficies de rodadura (2A, 3A), y - las secciones inductoras largas (8A, 9A) están dispuestas de tal manera que por lo menos uno de los cuadrantes superiores (I, II) del perímetro del gorrón abarcan por lo menos 60º, caracterizado porque - las secciones largas inductoras (8A, 9A) presentan en conjunto una anchura que es mayor que la mitad de la anchura total (B) de la superficies de rodadura (2A, 3A), - las secciones inductoras largas (8A, 9A) presentan siempre una dirección periférica del cigüeñal (1) una separación (E), y - las secciones inductoras largas en los cuadrantes inferiores (III, IV) que limitan en el cuadrante superior (I, II) abracan por lo menos 30º.
