前言本试验研究是针对矿井SGW-40、80型可弯曲刮板输送机上的一级轴圆弧伞齿轮,经高浓度碳氮共渗工艺处理后,试验了耐磨性、静弯、冲击、疲劳等性能,并与常规渗碳、碳氮共渗工艺作了对比,结果表明,20CrMnTi钢制齿轮采用高浓度碳氮共渗工艺是适宜的。一、试验方法1.高浓度碳氮共渗介质含氮化合物介质种类很多,但三乙醇胺应用效果较好,故用其作为主要共渗介质。由于三乙醇胺粘度大,流动性差,需加入一定量的工业酒精稀释,比例为三乙醇胺:酒精=3:1。为提高渗层的碳含量,用双头滴油
Preface The experimental study is aimed at the first-class shaft arc bevel gear on SGW-40 and 80 bendable scraper conveyors. After high-concentration carbonitriding process, the wear resistance, static bending, impact, Fatigue and other performance, and compared with conventional carburizing, carbonitriding process, the results show that 20CrMnTi steel gear with high concentration carbonitriding process is appropriate. First, the test method 1. High concentrations of carbonitriding medium There are many types of nitrogen-containing compounds, but triethanolamine application is better, so use it as the main infiltration medium. Triethanolamine viscosity, poor liquidity, the need to add a certain amount of industrial alcohol dilution, the ratio of triethanolamine: alcohol = 3: 1. In order to improve the carbon content of the layer, use double drop of oil
