摘要

为解决目前齿轮超声滚压强化因设备的限制及振动的单一性导致强化效率低、作用范围小等问题，提出了一种新的对滚式齿轮纵扭复合超声滚压系统，包括纵扭复合变幅杆及与之匹配的工具齿轮。基于理论计算的方法推导出圆锥形复合变幅杆频率方程，求得相关设计参数。在圆锥段开螺旋槽并装配齿轮，利用有限元分析方法研究纵扭复合振动、计算齿面处纵扭复合振动位移及轨迹。采用单因素变量法及有限元分析方法并引入参数扭纵振比，研究槽数、槽深、槽宽、螺旋角等不同螺旋槽参数对纵扭复合超声振动的影响规律，得到最优的参数组合，采用轻量化方法设计出工具齿轮。结果证明，纵扭复合变幅杆设计满足要求，齿轮轻量化设计并装配后得到有效纵扭复合振动。在圆锥形复合变幅杆圆锥段开槽可产生纵扭复合振动，扭转振动效果主要与螺旋槽槽数、槽深、槽宽、螺旋角等参数相关；与工具齿轮装配得到对滚式齿轮纵扭复合超声滚压系统，为新的齿轮纵扭复合超声滚压装置工作性能达成提供了技术支撑。

Abstract

This study attempts to solve the problems such as low efficiency and relatively small range due to the constraints of device and monotony of vibration in ultrasonic assisted rolling of gears. A novel double-roller longitudinal torsional compound gear ultrasonic rolling system including a longitudinal torsional compound horn and its matching tool gear is proposed. Through the theoretically calculation method， the frequency equation of the horn is derived and the relevant design parameters are calculated. The longitudinal torsional compound vibration displacement and trajectory at the tooth surface are calculated by FEM with spiral grooves in the conical section and the assembled gear. The influences of different parameters of spiral groove such as number， depth， width and helical angle of the groove on torsional longitudinal compound vibration is analyzed by univariate method， FEM and an introduced parameter torsional longitudinal vibration ratio. The optimal parameter combination is obtained and the tool the gear is designed by using lightweight design method. The results show that the design of compound horn meets the requirements， and the effective longitudinal torsional compound vibration of the assembled gear is obtained. The longitudinal torsional compound vibration can be generated with spiral grooves in the conical section. The torsional vibration is mainly related to the number， depth， width and helical angle of the grooves. The double-roller gear longitudinal torsional compound ultrasonic rolling system is obtained by assembling with tool gear， it provides a technical support for the performance of the new gear longitudinal-torsional ultrasonic rolling device.
