TLDR
In this article, a process method for quenching a rotary support gear is described, which comprises the main steps of carrying out rough turning, finishing turning, gear shaping, quenched and tempering on an inner ring and an outer ring of the rotary gear.Abstract:
The invention discloses a process method for quenching a rotary support gear. The method comprises the main steps of carrying out rough turning, finishing turning, gear shaping, quenching and tempering on an inner ring and an outer ring of the rotary support gear; an inductor of a quenching device for quenching adopts a medium frequency quenching inductor; the quenching liquid is PGA (polyglycolic acid) quenching liquid; the quenching device comprises a rotary workbench; one side of the rotary workbench is provided with a fixing base capable of vertically moving; a slide base that moves horizontally is erected on a horizontal side plate on one side of the fixing base; the slide base is fixedly provided with a transformer for driving the medium frequency quenching inductor and assisting a localizing guide rod to operate; the induction head on the front end part of the medium frequency quenching inductor is trapezoidal; a coupling gap between the induction head and the dental groove corresponding to the induction head is reserved when the induction head matches with the dental groove corresponding to the induction head; in the quenching process, the process parameters such as the coupling gap between the medium frequency quenching inductor and the dental groove, the entering depth of the current, the speed of the dental groove line, the temperature and the concentration of the quenching liquid are set and regulated; and, the method provided by the invention enhances the quenching quality, and is particularly suitable for the quenching need of the rotary support gear made of the material 50 Mn or the material 42 CrMo and with the module of gear more than 6.read more
