以一个经过抛光和浸蚀的美国费城齿轮厂感应淬火后的轮齿为例,其外部经表面渗碳硬化,芯子进行了热处理,因而齿的强度大、齿面耐久。请注意,自齿侧经齿根直至下一个齿侧均经均匀齿面淬火,完全不会出现缩短齿轮寿命的应力集中。感应淬火的温度极高,但只限于局部高温。本公司一次只淬一个齿,齿轮其他部分可以散热。用这种方式生产出来的齿轮表面淬火均匀、芯子韧性 Taking a polished and eroded gear tooth factory in Philadelphia, USA as an example, the outer surface is carburized and hardened, and the core is heat-treated. Therefore, the strength of the tooth is high and the tooth surface is durable. Please note that there is no stress concentration that shortens the life of the gear at all from the tooth flank to the tooth flank until the next tooth flank is evenly toothed. Induction hardening temperature is very high, but only for local high temperature. The company only quenches a tooth, the other parts of the gear can heat. The gears produced in this way are surface-hardened and the core is tough
