齿轮高频淬火变形是一个很复杂的问题,影响变形的因素很多,例如齿轮的原始组织,加工应力,热处理工艺规范,操作方法以及感应器结构等等。即使对上述各因素都严格控制也不可能不产生变形,但却可以使变形减小。我们在生产中对齿轮进行了多次测量,并与机械加工配合进行了一些试验,在本总结中将对伞齿轮的一般变形规律,产生变形的原因以及防止方法加以分析。一、伞齿轮变形的特点:伞齿轮在高频淬火过程中应用通常的方法都使内孔趋于缩小,但沿齿轮中心线的不同部位的变形情况 Gear induction hardening deformation is a very complex issue, many factors that affect the deformation, such as the original organization of gears, processing stress, heat treatment process specifications, methods of operation and sensor structure and so on. Even if the above factors are strictly controlled, it is impossible not to produce deformation, but it can reduce the deformation. We have conducted many measurements of gears in production and conducted some experiments in cooperation with machining. In this summary, we will analyze the general deformation rules of bevel gears, the causes of deformation and the prevention methods. First, the bevel gear deformation characteristics: bevel gear in the high-frequency quenching process using the usual methods are to make the hole tends to shrink, but along the gear center line of different parts of the deformation
