“…Continuous generating grinding has the advantages of high efficiency and high precision, and has become an important gear processing method [16]. In terms of generating grinding, optimizing the correction curve, adjusting the machine tool axis correction amount, and changing the shape of the worm wheel are the primary ideas to eliminate the twist error.…”

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.

“…A beveloid non−circular gear transmission scheme was developed by J Han to improve stability and accuracy, reducing meshing impact and allowing backlash adjustment [11]. An adaptive design model is proposed by Bing Cao et al for the continuous generation of beveloid gears in common gear grinding machines [12].…”

The internal beveloid gear has good scientific research value and a broad application field. However, there is a lack of research on the nonlinear vibration characteristics of internal beveloid gears. The present study establishes a nonlinear vibration model that takes into account axial vibration, gear torsional vibration, and radial support vibration. The effects of various excitation parameters on the vibration characteristics of the gear transmission system are analyzed and computed using the Runge–Kutta method. After analyzing the dynamic model of the gear pair using numerical methods, the harmonic balance method is employed to obtain the theoretical analytical solution for a single−stage gear. The obtained results are compared with the velocity and acceleration time−domain response curves obtained from the numerical method, and they show excellent agreement.
