齿轮的寿命和运行在很大程度上取决于接触表面的性质，这些性质在齿轮寿命期间不可避免地发生变化。磨合过程中的初始形貌变化是一个重要的特征效应。本文着重于如何磨合的表面形貌的特点，什么方法可以用于此目的。为了表征磨合，齿轮在FZG背靠背试验台上运行，并使用Form Talysurf Intra原位测量表面形貌的变化。这使得相同的齿轮齿面能够以足够的精度进行测量，以跟踪其在跑合的不同阶段的发展。在三种情况下测量所制造的齿轮齿面：在初始制造条件下，在标准跑合程序之后，以及在效率测试之后。运行的特点是定性绘制粗糙度曲线和定量分析选定的一组粗糙度参数。本文证明：粗糙峰在初始磨合阶段被磨掉;粗糙度、波纹度和形状可以使用仔细选择的多项式拟合和高斯滤波器来分离;表面形貌可以在初始、磨合后和原位操作后进行检查;并且在特定情况下可以观察到初始表面的完全磨损。(C)2015 Elsevier B.

Gear life and operation are largely determined by the properties of the contacting surfaces, which inevitably change over the gear life. The initial topography transformation, a characteristic effect of running-in, is very important. This paper focuses on how the running-in of the surface topography can be characterized and what methodology can be used for this purpose. To characterize running-in, gears were run in an FZG back-to-back test rig and the changes in surface topography were measured in situ using a Form Talysurf Intra. This enables the same gear tooth surface to be measured with enough precision to follow its development through the different stages of running-in. Gear tooth surfaces as manufactured were measured on three occasions: in initial manufactured condition, after a standard running-in procedure, and after an efficiency test. Running-in was characterized both qualitatively by plotting roughness profiles and quantitatively by analyzing a selected set of roughness parameters. This paper demonstrates that: the asperity peaks were worn off in the initial running-in stage; roughness, waviness, and form can be separated using a carefully chosen polynomial fit and the Gaussian filter; surface topography can be examined initially, after running-in, and after operation in situ; and complete wear of the initial surface can be observed in specific circumstances.
