Abstract: Through the practical application of centrifuge gear selection, a method for measuring the cooling rate of the gear core is found, providing a basis for selecting suitable hardenability materials and reliably ensuring the hardness of the centrifuge gear core. Finally, the actual experimental data and practical application verify that the application of G20CrNi2MoH steel to X and R series gears can ensure the hardness of the actual core, while K series gears must use 17CrNiMo6 steel to ensure the hardness of the actual core.

Key words: centrifuge gear, material selection, core hardness, core cooling rate, hardenability
