我们曾在本刊1967年第三期中谈过齿轮的麻点、崩齿、齿牙压碎、齿面压碎及轴柄折断等五个问题。本文着重谈齿轮表面组织对齿牙破损的影响。屈氏体对齿轮破损的影响齿轮在热处理淬火时,由于冷却速度过缓或齿牙表面含碳量偏低,使齿牙表面的金相组织为马氏体+网状屈氏体(见图1～3),造成齿牙表面早期磨损和压
We have talked about five issues in the third issue of the journal, 1967, such as pitting, collapsing teeth, crushing of teeth, crushing of tooth flanks and fracture of the shaft. This article focuses on the influence of gear surface structure on tooth damage. Effect of troostite on gear breakage When the gear is quenched in heat treatment, the microstructure of the tooth surface is martensite + reticular troostite due to the slow cooling rate or the low carbon content of the tooth surface 1 ~ 3), resulting in early wear and tear on the tooth surface
