Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, and more specifically to a gear carburizing and quenching device. Background Technique

[0002] Gear carburizing and quenching is a surface treatment process to improve the hardness and wear resistance of gears. This process mainly includes two steps: gear carburization and quenching treatment. By exposing the gear surface to a high-temperature furnace containing a carbonizing agent, under certain temperature and time conditions, carbon elements diffuse into the gear surface to form a certain carburized layer. The surface hardness and wear resistance of the carburized gear are significantly improved.

[0003] When the existing gears are carburized and quenched, the gears need to be manually placed inside for quenching, which is relatively dangerous for users. And after quenching, the gears still need to be taken out from the outside of the limit posts. The gears have a high temperature after quenching, and it is rather troublesome to take them, resulting in low structural safety. Therefore, a gear carburizing and quenching device is provided.
