摘　　要：渐开线圆柱齿轮齿廓测量中采样方式的不同会对齿廓偏差产生影响,而标准中未对其进行规定.依据采样定理,首先通过齿廓形状偏差的临界频率确定出齿廓上的采样频率;然后,利用所测齿轮精度等级与齿面粗糙度标准之间关系,确定出齿廓展开长度上的理论采样间距;最后,进行齿廓偏差采样实验.验证结果表明:所提出的采样方法是可行的.Different sampling methods would affect tooth profile deviation in involute tooth profile measurement,while the standard has provided anything about it.In this paper,based on the sampling theorem,first of all,the sampling frequency of the tooth profile would be determined by critical frequency of tooth profile shape deviation,then the relationship between the accuracy class and the tooth surface roughness standards is used to determine the theoretical sampling in the longitudinal direction of the tooth profile expanded,and finally the experiment of tooth profile deviation sampling is conducted and verified.The results demonstrate that the method is feasible.
