6级以上精度的淬火齿轮,采用展成磨齿精加工,其效率低、成本高。我校已创造出一种经济成型磨齿法。在没有齿轮磨床的条件下,只需少量的投资就能加工6级精度的齿轮。新加工法的效率较锥面砂轮展或磨齿高一倍以上,成本降低50％以上。本文介绍成型磨齿的表面质量研究成果。 Quenching more than 6 precision gear, the use of the exhibition into grinding gear finishing, its low efficiency, high cost. Our school has created a kind of economic forming grinding method. In the absence of gear grinding machine conditions, with only a small amount of investment can be processed 6 precision gear. The efficiency of the new processing method than the cone wheel grinding or grinding teeth more than doubled, reducing the cost of more than 50%. This article introduces the research results of the surface quality of profile grinding teeth.
