“…Taking the right tooth flank in figure 2 as an example, the tooth profile error model at the upper and lower end faces of the gear is established. It is assumed that the lead modification curve of the right tooth flank is a drum-shaped curve [24], and the tooth root and tip of the upper end face correspond to contact traces 3 and 4, respectively. The drum-shaped modification curve is shown in figure 3.…”

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.

“…This was achieved by altering the tooth profile and inclination angle of the shaving cutter. Tran, VQ et al [10] proposed a novel approach to attain the tooth profile and longitudinal modification of long -face wide helical gears. This objective is accomplished through the utilization of a numerical control internal gear honing machine.…”

In order to achieve gear longitudinal modification and improve gear grinding efficiency, a novel gear grinding methodology is proposed, and the method of accurate control of longitudinal modification values is given. The core principle is that the grinding disc is installed obliquely to generated grinding teeth, and cubic boron nitride (CBN) is sintered on the grinding disc. Firstly, the principle of a novel gear grinding methodology is expounded. Secondly, based on this methodology, the control and adjustment model of longitudinal modification values is established, and it is concluded that the longitudinal modification values can be accurately controlled by the installation angle of the grinding disc. Finally, the effectiveness of this grinding methodology in achieving the whole teeth width grinding of gears and longitudinal modification, as well as improving gear grinding efficiency, is confirmed through VERICUT machining simulation; then, the analysis of tooth contact in the grinding gear pair revealed that longitudinal modification can effectively reduce the edge contacts, which can make the tooth surface load evenly distributed in tooth width direction.

“…Han [4] developed a mathematical model for lead and profile crowning modification of work gear by setting the movement of the honing wheel as two forth-order polynomial functions. Wu [5][6][7][8] presented methods for topology modification of helical gears using internal-meshing gear honing. Parallel, many researchers investigate the contact conditions, cutting force vibration, and teeth elastic deformation of honing wheel in the honing process, aiming at improving the honing performance.…”

Ring gear is an important transmission component, but restricted by its ring-shape structure, the tooth surfaces are pretty hard to be finished after heat treatment. Honing is the most commonly used finishing technique for external gear, but for ring gear, it is inconvenient. In this paper, a new type of cone-shape honing wheel is proposed and the honing mechanism is studied for improving the honing performance of ring gear. First of all, the mathematical model of the honing technology by use of cone-shape honing wheel is built, and the merits of the new honing method are discussed. Then, the contact conditions between the honing wheel and the work gear are analyzed, and it is found that the tool tilt angle of the honing wheel has good influences on the honing mark distribution of the work gear. Finally, the honing simulations for ring gear by use of cone-shape honing wheel are carried out, by which the feasibility of the new honing technique are verified.
