摘要
采用正交试验法研究了加热温度、保温时间、工件冷却时间、搅拌速度等四种因素对61810轴承外圈椭圆变形、硬度和组织的影响。结果表明,套圈硬度和组织均能满足技术要求,工件冷却时间对椭圆变形影响较大,搅拌速度次之。通过试验,确定了61810轴承外圈的最优热处理工艺参数。
The effects of the heating temperature, holding time, workpiece cooling time, stirring speed and so on four kind of factors on the bearing outer ring 61810 elliptical deformation, hardness and organization were studied by the orthogonal experiment method, the results showed that the ring stiffness and organization could meet the technical requirements, the influence of workpiece cooling time on elliptical deformation was greater, followed by the stirring speed. Through the experiment, most superior heat treatment craft parameter of 61810 bearing outer ring had been identified.
