摘要
提出了直齿面齿轮的碟形砂轮磨齿方法,根据磨齿加工原理,建立了碟形砂轮磨齿加工模型,利用磨齿加工过程中对小轮的双向修形来实现面齿轮副的啮合性能优化,推导了面齿轮齿面和小轮修形齿面方程。算例表明,对小轮磨齿加工参数和修形参数的调整,可使齿面接触迹线的位置和方向得到改善,从而降低面齿轮副对安装误差的敏感性,并得到抛物线传动误差,有效减小因安装误差引起的振动与噪声。
A grinding method of spur face-gear drive with dish wheel was presented.Based on the generation process of face-gear grinding,a mathematical model for gear grinding with dish wheel was established and the expressions of tooth face equations of face-gear drive were provided,respectively.From the numerical examples,it is proved that the position and orientation of the contact path of tooth face can be improved by changing the machine tool settings and modification parameters of the pinion,which will reduce sensitivity of the gear drive to misalignments.At same time,the predesigned parabolic function of transmission errors can be obtained,which will reduce noise and vibrations of the face-gear drive efficiently.
