“…Face-hobbing cutter is widely used in the manufacture of external spur gears [38]. As the basic geometry of the cutter includes a rack, the cutting process can be regarded as the meshing of a gear and a rack [39].…”

Tooth surface wear damage is one of the main causes of gearing system failure. Excessive wear leads to tooth profile loss and an increase in transmission errors, as the worn gear surfaces are no longer conjugate. Thus, the enhancement of gear durability against wear is important for gear application. Recent works show that cutter modification can aid in reducing the tool wear in gear processing, while the wear performance of the gears produced by modified cutters is still unknown. Therefore, this study focuses on the wear performance of the gear generated by modified cutter. Numerical results show that the wear resistance can be enhanced through proper cutter modification.

“…Lead modification is usually performed by changing the center distance between the tool and the gear. However, this change in center distance creates a twisted tooth flank on the gear, which may induce transmission errors of the work gear pairs, and cause the tooth wear and noise of the mating gear pair [7,8]. To reduce the twist of the crowned helical tooth flank, Tran [9] proposed a nonlinear function of additional rotation angle for the helical gear during its hobbing process.…”

A compensating method based on continuously deflecting the dressing wheel is proposed to eliminate twist error of the lead modification tooth flank. Combining the tooth flank contact trace and the lead modification curve, the mechanism of the twist error of the modified tooth flank is first analyzed. Second, a tooth profile error model is developed at the upper and lower end faces. The tooth flank twist amount is calculated by subtracting the tooth profile error at the upper and lower end faces. Then, the tooth profile slope deviation of the twisted tooth flank is transformed into the pressure angle deviation of the tooth profile, and the method of compensating the pressure angle of the worm wheel is applied to eliminate the pressure angle deviation of the tooth flank caused by the twist error. The grinding partition of the worm wheel is performed according to the diagonal grinding process, and a worm wheel dressing method for continuously deflecting the dressing wheel is provided to compensate for the twist error of the lead modification tooth flank. Finally, the continuous generating grinding experiment of the lead modification gear verifies the feasibility of the proposed method.

“…The deviations could be separated into each degree of freedom of the machine and each degree of freedom is corresponding to each axis of the machine. According to compensating the error of each axis, the deviation of the flank could be adjusted (Shih and Chen, 2012;Tang et al, 2014;Jiang and Fang, 2015). This method could be transplanted to the TP worm manufacture.…”

Planar enveloping hourglass worm (TP worm) with better load capacity and transmission efficiency is a type of transmission superior to traditional cylindrical worm. It could be used to lightweight design. As the flank of the worm is a complex toroidal surface, higher demands are needed for the manufacture and the assembly. This paper proposes a new principle to adjust the processing precision of the worm. The principle is based on the research on the influence of the parameter errors on the deviations of the feature lines on the flank. With different types of parameter errors, the shape and the value of the deviation curves of the feature lines are different. At last, two cases are introduced to verify that the principle could be used to improve the precision of the TP worm.
