Unfortunately, the heat treatment process usually produces distortion of the gear, with the result that gear load is not uniformly distributed across the gear tooth face.

不幸的是，热处理过程通常会使齿轮发生扭曲和形变，这样齿轮上的载荷就不能均匀的分布到轮齿的表面。

The drawback with GB3480-83 Methods for the calculation of load capacity of involute cylindrical gears equivalent to ISO/DP6336/Ⅰ∽Ⅲ-1980 is also pointed out: when taking into account lubricating state of gear surface influence on loading capacity of gear surface, In the above it is study on based EHL, and is ignored that in the state of boundary lubricating, as well as favorableness conditions in gear surface conjugate meshing, the active atom resolved from the additive permeates the surface and forms the modifying layer totally different from its basic structure, elements and function and thus greatly raises the loading capacity of gear surface.

也指出了等效于ISO/DP6336/Ⅰ∽Ⅲ-1980的《GB3480-83渐开线圆柱齿轮承载能力计算方法》的缺陷：在考虑齿面间润滑状态对齿面接触强度承载能力影响时，是以弹性流体动力润滑理论为讨论问题的基础，未考虑边界润滑状态下，非活性润滑油抗磨添加剂在啮合过程中，由于各种有利因素会分解出活性原子，渗进齿轮表面，形成表面改性层，极大的提高了其承载能力。
