In view of the limitation of the existing single error evaluation methods,this paper uses the method of spatial evaluation. Firstly,the mathematical model of involute topological modification tooth surface and the actual tooth surface model of involute topological modification are constructed. Then,Dimensional tooth surface and the actual topology of the tooth surface to match the three-dimensional,and finally establish a spatial evaluation model. The method can evaluate the topological shape of the tooth surface and extract the single tooth surface error. The method can also measure and evaluate the error of topological modified helical gears,which provides a theoretical basis for the overall measurement and evaluation of gears in space.
