寻求提高齿轮类另件的感应加热淬火质量,是目前普遍存在的热处理技术关键。在原频率为200～250KC 的高频设备上添加频率为30～50KC 的超音频部分,理论上是可行的,实际上也是容易实现的。利用超音频感应加热处理,对于提高齿轮类另件的质量,效果显著。本文从理论上对超音频感应加热设备振荡线路的选择及其元件参数的计算、制作和选用进行了论述;对超音频设备的结构特点、调整与功率效率作了叙述,对在调试过程中出现的一些问题作了说明;并进行了超音频加热的工艺试验,其结果表明,对于一般常用中小模数齿轮以及凸轮轴、花键轴易于实现仿形硬化。
Seeking to improve the quality of induction heating and quenching of gear parts is the key to the ubiquitous heat treatment technology. In the original frequency of 200 ~ 250KC high-frequency equipment to add the frequency of 30 ~ 50KC super audio part of the theory is feasible, in fact, is also easy to achieve. The use of super audio frequency induction heat treatment, to improve the quality of the other parts gear, the effect is significant. In this paper, the choice of oscillating circuit of super-audio frequency induction heating equipment and the calculation, fabrication and selection of its components parameters are discussed in theory. The structural characteristics, adjustment and power efficiency of the super audio equipment are described. During the debugging process, Some of the problems were described; and the process of super audio frequency heating test, the results show that for the common small and medium modulus gear and camshaft, spline shaft easy to achieve the shape hardening.
