Lead Crowning and Anti-twist for Tooth Flank of a Heat Treated Helical Gear on Internal CNC Honing Machine

摘要

The internal gear honing is more popular than the external gear honing by its advantages such as higher contact surface and easier correct profile errors. It is usually applied for modifying the gear surface to compensate for the distortions after heat treatment process. However, the lead crowning and anti-twist tooth flank of a helical gear on internal CNC gear honing has not studied yet. Therefore, a novel method for lead crowning tooth flank of work gear surfaces is proposed by using a linear swivel angle function of the honing wheel and a variable pressure angle (VPA) honing wheel is also applied for anti-twist of the crowned tooth flank in honing process.
