Description

Technical Field

[0002] Gear quenching is a heat treatment process, the main purpose of which is to make the surface or the whole of the gear material (usually steel) meet certain organizational and performance requirements through the process of heating and rapid cooling. During the quenching process, the gear is usually placed in an inductor (coil), and an alternating current of a certain frequency is passed through to generate an alternating magnetic field around the gear, thereby generating an induced current (eddy current) inside the gear. Due to the skin effect, the density of the current on the surface of the gear is higher, so the heating is mainly concentrated on the surface of the gear. When the temperature of the heating layer exceeds the critical point temperature of the steel, it is quickly cooled to achieve surface or overall quenching of the gear. In the existing patent application with application number CN202121597279.8, a gear quenching device is proposed. The gear quenching equipment has a low degree of automation, which is not conducive to the rapid quenching of the gear, resulting in low quenching efficiency of the gear, so it needs to be improved.
