我厂配套矿山采掘、装载等机械的12马力、20马力风马达,其中定子是一个形状复杂、精度较高的零件,我们在小批量试生产中,采用了不同的热处理方法,并对定子的变形进行了比较。其中以离子氮化为最好,现介绍如下:一、渗碳、淬火对定子变形的影响定子材料:20Cr;渗碳层深度:1.5～2.0毫米;要求硬度 Rc=58～62。其热处理工艺见图1。 I plant supporting mining mining, loading and other mechanical 12 horsepower, 20 hp wind motor, the stator is a complex shape, high precision parts, we in small batch of trial production, using a different heat treatment, and the stator Deformations were compared. One of the best for the ion nitriding, are described below: First, the effect of carburizing and quenching on the stator deformation Stator material: 20Cr; carburized layer depth: 1.5 to 2.0 mm; required hardness Rc = 58 ~ 62. The heat treatment process shown in Figure 1.
