新型环面蜗杆副由蜗杆、钢球和蜗轮构成,利用失配共轭技术,提高了其承载能力和适应性。在分析蜗杆廓面结构特征的基础上,给出了蜗杆廓面的准线方程,提出了基于准线的成形法加工方法,着重分析了加工过程中的原理性误差,推导出了廓面法向误差公式。以一组数值参数为例,绘制了齿形误差和齿向误差图,并在OpenGL平台上进行误差可视化处理。结果表明:成形法加工的蜗杆廓面齿形和齿向误差值较小,能够保证获得高精度的传动廓面。
The new toroidal worm consists of a worm, a steel ball and a worm gear, utilizing mismatched conjugate technology to improve its carrying capacity and adaptability. Based on the analysis of the structural characteristics of the worm profile, the quasi-line equation of the worm profile is given, the method of forming based on the quasi-line is proposed, the principle error in the machining process is analyzed emphatically, and the profile method To the error formula. Taking a set of numerical parameters as an example, the tooth profile and tooth profile are plotted, and the error visualization is performed on the OpenGL platform. The results show that the tooth profile and tooth orientation errors of the worm profile processed by the forming method are small, and the transmission profile with high precision can be guaranteed.
