According to the definition of tooth surface error in Chapter 4, it is used to represent the error between the target tooth surface of the small wheel and the theoretical tooth surface of the small wheel, as shown in the formula
Or:
Where {δ I} is the tooth surface error of all discrete points on the target tooth surface and the theoretical tooth surface of the pinion; AIJ is the quadratic term coefficient matrix of the pinion machining parameter adjustment group; bij is the primary term coefficient matrix of the pinion machining parameter adjustment group; CIJ is the constant term coefficient matrix of the pinion machining parameter adjustment group; P is the number of processing parameters.
Through the above analysis, according to {δ I}, AIJ, bij and CIJ, the adjustment group {Δ RJ} can be obtained.
