摘要: 为有效解决SAE5120钢制轴承套圈渗碳淬火后畸变较大的问题,对渗碳后的轴承套圈进行了感应矫形模压淬火。结果表明,与常规渗碳相比,经感应矫形模压淬火后轴承套圈的表面及心部马氏体细化,硬度提高,轴承套圈的畸变明显降低,从而可以削减磨削余量,起到降低生产成本和提高生产效率的效果。

关键词: 轴承套圈, 渗碳, 模压淬火, 畸变, 磨削余量

Abstract: In order to solve the problem of severe distortion of the SAE5120 steel bearing ring after carburizing and quenching, an induction fixture hardening process was carried out. The results show that, compared with conventional carburizing and hardening, the surface and core martensite of the bearing ring are refined, the hardness is increased, and the distortion of the bearing ring is significantly reduced. It is possible to reduce the grinding allowance, save the production cost and improve the production efficiency.

Key words: bearing ring, carburizing, fixture hardening, distortion, grinding allowance
