The Relationship Between Effective Hardened Layer Depth and Barkhausen Noise of Gear Material
摘 要
齿轮的渗碳和热处理工艺决定了其耐磨、抗疲劳强度,合理的有效硬化层深度可以提高齿轮的承载力,延长齿轮的使用寿命。针对齿轮加工常用材料18CrNiMo7-6钢,采用巴克豪森噪声检测方法,分析了材料热处理的有效硬化深度指标。试验发现,巴克豪森噪声信号随齿轮材料的有效硬化层深度的增加而呈逐渐减小的规律。
Abstract
Carburization and heat treatment process of gear determines its abrasion resistance and fatigue strength. The reasonable effective hardened layer depth can improve the bearing capacity of gear and prolong its service life. Barkhausen noise detection method is used to analyze effective hardened layer depth. Testing results show that Barkhausen noise signal will diminishing with the increase of the effective hardened layer depth of the gear material.
