针对硬齿面双圆弧齿轮存在的砂轮端面廓形计算复杂、磨削干涉的问题提出了一种成形磨削方法。根据齿轮啮合原理,得到双圆弧齿轮的基本齿廓和齿面方程式。在此基础上,对双圆弧齿轮的成形磨削接触条件和砂轮廓形进行求解。最后,在双圆弧齿轮成形磨削实例中,分别通过仿真切削加工和磨齿实验验证所提方法的有效性。实验结果表明,该方法有效地解决了硬齿面双圆弧齿轮成形磨削的技术难题。 Aiming at the complicated calculation of grinding wheel face profile and grinding interference existed in the double-arc gear with hardened tooth surface, a forming grinding method is proposed. According to the gear meshing principle, the basic tooth profile and tooth surface equation of the double arc gear are obtained. Based on this, the forming contact condition and profile of the double circular arc gear are solved. Finally, in the case of double arc gear grinding, the effectiveness of the proposed method is verified by simulation cutting and grinding experiments respectively. The experimental results show that the method effectively solves the technical problems of the forming grinding of hardened double-arc gear.
