滚子在轴承中,承受着拉伸、压缩、弯曲、剪切和交变等复杂应力,因此要求其原材料应具备:接触疲劳强度高,耐磨性好,弹性极限高,韧性好,尺寸稳定性好,防锈性能强和加工性能良好。 一、滚子常用的钢种 1.高碳铬轴承钢 高碳铬轴承钢又名铬轴承钢或滚铬钢。长期使用证明,这种钢基本可以满足在一般工作条件下的轴承滚子的要求,其使用量在我国约占轴承用钢的
Roller bearings, subject to the tensile, compression, bending, shear and alternating and other complex stress, requiring its raw materials should have: contact fatigue strength, good wear resistance, high elastic limit, good toughness, dimensional stability Good, rust-proof and processing performance is good. First, the commonly used steel roller 1. High-carbon chromium bearing steel High-carbon chromium bearing steel, also known as chromium bearing steel or rolled chromium steel. Long-term use of proof, this steel can basically meet the requirements of the bearing roller under normal working conditions, the amount of its use in our country about bearing steel
