摘要
为提高精锻成形的弧齿锥齿轮齿面的接触性能,根据小轮切齿加工参数和相应的齿面模型,构建与小轮齿面符合设定传动关系的完全共轭大轮齿面.以该齿面为基准面,提出一种二阶easeoff齿面构建方法.根据构建的大轮离散目标齿面,采用离散齿面轮齿接触分析的计算方法,以临界干涉法判断啮合状态,得到离散齿面的啮合印痕和传动误差曲线,所得传动误差与预置传动关系基本吻合.分析了二阶ease-off齿面参数对传动误差曲线及齿面接触区的影响,结果表明:ease-off各变量可实现对接触椭圆长度、接触迹线角度、接触区位置的精确控制.
To improve the contact performance of precision forging spiral bevel gear,a fully conjugated gear surface with predesigned transmission relation was established based on the pinion tooth surface model and the pinion machining-tool parameters.Taking the conjugate surface as base level,an approach was proposed to built second order ease-off surface.Based on the discrete tooth surface,the contact pattern and the transmission error curve were obtained by computational method with the critical interference judging of meshing state,and the simulation results were basically consistent with the predesigned transmission relation.The effects of second order ease-off surface parameters on the transmission error curve and contact pattern of tooth surface were also investigated.The results show that the accurate control on the length and location of the contact ellipse and the angle of the contact path can be realized by the ease-off surface parameters.
