“…The matrix L 2s (f s , c t , z t ) is obtained by deleting the last column and row of the transformation matrix M 2s (f s , c t , z t ), as shown in equation (8). Solving equations (6), (7), (9), (11), (12), (13) and (14) defines the tooth surface of the shaved work gear that is produced using the proposed auxiliary crowning method.…”

“…Seol and Litvin 13 proposed a modified geometry for the involute spur and helical gears with parallel and crossed axes that are used in gear shaving, which localizes and stabilizes the bearing contact and reduces noise and vibration. More recently, Hung et al 14 and Chang et al 15 developed a mathematical model for a shaved gear with auxiliary crowning that takes into account both the parameters for the gear shaving machine and cutter assembly errors. Although this is still considered to be a standard pitch cylinder model, further study of the meshing point between the work gear and the shaving cutter during pitch cylinder operation was needed.…”

For a parallel gear shaving process, the tooth flanks of a shaved work gear surface are longitudinally crowned using an auxiliary crowning mechanism. However, the flanks are only crowned in the longitudinal direction and not in the cross-profile direction so there is a natural twist on the shaved work gear surfaces. A new shaving method for double-crowning that has no natural twist in the tooth flanks on the work gear surfaces is proposed, which uses a variable pressure angle shaving cutter in a parallel gear shaving process. Three numerical examples are presented to verify the merits of the proposed shaving method. The tooth flanks are crowned in both the cross-profile and the longitudinal directions, and natural twists in the shaved tooth flanks are reduced significantly.

“…The investigation results show that the internal gear honing is most efficient process for gear finishing and it provides an excellent surface finish of work gear compared with other gear finishing processes. Hung et al [14] and Chang et al [15] developed a mathematical model of the shaved gear with an auxiliary crowning by taking into account the setting parameters of the gear shaving machine and cutter assembly errors. However, the developed model was considered at the standard pitch cylinder.…”

The gear honing is the most economical way for hard finishing an involute helical gear after hobbing and heat treatment or after shaving and heat treatment. The gear honing can also be applied to the modification of gear tooth surfaces to compensate for the distortions that occur during heat treatment process. Most published papers on the technology of gear honing describes on the principle of generated gear surface. However, the longitudinal tooth flank crowning of a helical gear with honing has not been investigated yet. Therefore, in this paper, we proposed a novel method for longitudinal tooth flank crowning of work gear surfaces by setting a crossed angle between the honing cutter and work gear axes as a linear function of honing cutter's traverse feed in the honing process. A mathematical model for the tooth profile of work gear honed by a standard honing cutter is also established. Three numeral examples are presented to illustrate and verify the merits of the proposed gear honing method in longitudinal crowning.
