Abstract
The latest research clearly demonstrates the excellent capability of the gear skiving technology. To improve the twisted flanks of cylindrical gears when performing a lead modification in skiving process, a correction method is proposed. First, a kinematic model of power skiving and correction tooth surface are established based on the engagement principle of crossed helical gear. The phenomenon of flank twist in the skiving process is investigated and the counter lines of modified error on both flanks are obtained. Then, a correction method for cylindrical gears lead modification is proposed to correct the twisted tooth flanks by optimizing the cutter profile. In this method, the cutter profile is formulated as B-spline curves using a curve fitting technique, and a sensitivity matrix and correction polynomial coefficients are derived. Thus, the skiving tooth flank can be approximated to the desired tooth flank by adjusting the coefficients of the polynomials. Finally, a numerical example shows that the optimization method of cutter profile can effectively reduce the modified errors as well as improve the modification twist in gear skiving process.
