基于保证齿轮心部硬度的离心机齿轮选材方法

Material selection method of centrifuge gear based on ensuring gear center hardness

通过离心机齿轮选材的实际应用实例,找到一种衡量齿轮心部冷却速度的方法,为选择合适的淬透性材料和可靠保证离心机齿轮心部硬度提供依据。最终以实际的试验数据和实际应用验证确认G20CrNi2MoH钢应用于X和R系列齿轮能够保证实物心部硬度,而K系列齿轮必须采用17CrNiMo6钢,才能够保证实物心部硬度。

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.
