Abstract (en)
[origin: WO2010007635A1] A method and device for induction hardening rolling tracks (4)of bearing thrust blocks (3). At least two inductors are used (6, 8) initially arranged in tandem, which are held at a prefixed distance from a surface (2) of the track and parallelly to the same; the thrust block (3) is rotated at a first angular speed (V1) with respect to a first inductor (6), held fixed, while a second inductor (8) is rotated in the same direction as the thrust block but at a second angular speed (V2), double the first, so as to leave a first side (22) of the first inductor (6) and, essentially after a complete rotation, arrange itself sided to a second side (23) of the first inductor, on the side opposite to the first; simultaneously, the inductors are electrically fed and at least one cooling shower (13a, b,d), operatively connected to the other inductors (6, 8), is actuated.
