Analysis for surface quench cracks of big bearing ring;
大型轴承座圈表面淬火裂纹分析
The final mechanical property of bearing ring depends on the deformation, In order to make bearing ring have good quality and obtain high prouction efficieny, this paper analyzes multiple rolling range in the machining,rang of the equipment, considers the equipment capacity and the deformation of ring blank, and then sets a mathematical model of process parameter in rolling.
在设备能力范围内，分析了冷辗扩加工的综合辗压区，综合考虑了辗压时的力能参 数与环坯变形状态，建立了轴承座圈冷辗扩加工工艺参数分析的数学模型。
