摘　　要：【目的】齿轮硬化层深度是影响齿轮强度和承载力的关键因素之一。现有研究表明,齿轮不同的失效模式所要求的有效硬化层深度不同。传统的硬化层深度设计往往仅考虑了硬化层与模数的关系,未充分考虑齿轮服役环境、性能要求及失效模式等的影响,未真实反映硬化层深度的理论内涵。【分析】以渗碳淬火齿轮为例,汇总了国内外对有效硬化层深度研究的相关文献及标准;在此基础上,给出了齿轮不同失效模式下的有效硬化层深度设计方法,并给出了最佳硬化层深度的推荐值。[Objective]The depth of the hardened layer of gears is a significant factor influencing on strength and load-carrying capacity of gears.Modern research shows that different failure modes of gears require different effective hardened case depths.The traditional design of the hardened case depth often only considers the relation between the hardened layer and modulus,does not fully consider the influence of gear service environment,performance requirements and failure mode,and does not truly reflect the theoretical connotation of the hardened case depth.[Analysis]Taking the carburized and quenched gear as an example,the domestic and foreign literature and standards on the effective hardened case depth was summarized.The design method of the effective hardened case depth under different failure modes of gears was given,and the recommended value of the best hardened case depth was given.
