DISPOSITIVO PER L'INDURIMENTO SUPERFICIALE DI ALBERI A CAMME PER MOTORI A CUMBUSIONE INTERNA |
摘要 |
An apparatus for hardening the cam tracks of camshafts in which one or more camshafts to be hardened are mounted adjacent a master camshaft for synchronous rotation therewith. A plurality of burners are slidably mounted adjacent each track to be hardened for movement toward and away from the track. A follower on the corresponding track of the master camshaft controls movement of the burner. An eccentric oscillates a plate on which the camshafts are mounted to cover all of the cam track. The burner is turned on and off so that the zone of the cam base circle is not heated and remains unhardened. |
