Processing technology of spiral bevel gear

Before grinding the spiral bevel gear used for the test, ensure the same machining process and its machining process as the actual production. The surface before gear grinding is carburized and quenched, and the process flow of heat treatment (carburization and quenching) is as follows:

① Surface carburizing: keep heating at about 900 ℃ in the carburizing furnace for a certain time, and the carburizing layer depth is 1.0-1.4 mm.

② Quenching: furnace cooling to about 800 ℃, holding for a certain time, oil cooling.

③ Low temperature tempering: keep 180 ℃ for a certain time, and then cool the air to normal temperature.

The heat treatment process is completed, and the gear to be ground is shown in the figure.
