齿轮轮齿表面的加工方法很多,因加工方法不同而形成了各种加工纹理(图1中列举了几种常见的齿面加工纹理)。齿面的形状也较复杂。加工纹理的多样性和表面形状的复杂性给齿面粗糙度的测量带来了很多困难。目前国内外对齿面粗糙度的检查和测量有下列几种常用方法。 There are many ways to process the surface of gear tooth surfaces. Various processing textures are formed due to different processing methods (several common tooth surface processing textures are listed in FIG. 1). The shape of the tooth surface is also more complicated. The complexity of the processed texture and the complexity of the surface shape present many difficulties in measuring the roughness of the tooth surface. Currently at home and abroad on the tooth surface roughness inspection and measurement of the following commonly used methods.
