内燃机车和电力机车上有许多传动齿轮,尤其是用于牵引的主动齿轮和从动齿轮,因为受力大,必须增加表面硬度、磨损抗力和抗咬合力,提高疲劳强度和耐腐蚀力,为此经过机加工的齿轮需要热处理。 最近,铁道部科学院金化所研制成功了辉光离子氮化这一新型热处理装置的脉冲电源。它刚一问世就受到了用户的热烈欢迎。洛阳第一拖拉机厂专程到北京铁科院求购。其它用户纷至沓来,最初几台样机均被购走,就连做试验用的样机也被订购。 为什么这种专用的脉冲电源如此受宠呢?这还要从辉光离子氮化的神奇功能说起。
There are many transmission gears on diesel locomotives and electric locomotives, especially the driving gear and driven gear for traction. Because of the large force, it is necessary to increase the surface hardness, wear resistance and anti-bite force to improve the fatigue strength and corrosion resistance. This machined gear needs heat treatment. Recently, the Ministry of Railways Academy of Sciences Jinhua successfully developed glow ion nitriding pulse heat treatment of this new device. It was warmly welcomed by users as soon as it came out. Luoyang first tractor factory made a special trip to Beijing Iron ASTRI Buy. After other users, the first few prototypes were purchased, and even the prototype for testing was ordered. Why is this dedicated pulse power so favored? This also from the magical function of glow ion nitrilation.
