我们在机械修理工作中,常遇到一些齿轮有少数齿严重磨损,甚至轮齿折断而需要更换。为了及时修复和减少修理费用,我们用嵌补法修复齿轮,实践证明对于传动精度要求不高的齿轮是适用的。特别对于模数大、齿数多的大齿轮更有实用价值。修复过程是这样:在齿轮的损坏部位加工出燕尾槽,若被修复齿轮是淬火的,应先在拟加工部位局部退火(可用粘土包住不退火部位,再用乙炔焰加热退火部位),再将经加 We are in the mechanical repair work, often encountered some gear serious wear and tear of a few teeth, and even broken teeth and need to be replaced. In order to promptly repair and reduce the cost of repairs, we repair the gear with the interpolation method, the practice proved that the gear accuracy is not high for the gear is suitable. Especially for the modulus, the number of large gear more practical value. The repair process is as follows: The dovetail groove is machined into the damaged part of the gear. If the gear to be repaired is quenched, local annealing at the part to be machined (clay can be used to envelop the un-annealed part and acetylene flame to heat the annealed part) Will be added
