摘要
针对目前内齿轮加工方法中普遍存在的精度低、效率低等不足,提出一种运用鼓形蜗杆刀具进行内齿轮连续分度的展成加工方法。以微分几何和啮合原理为基础建立鼓形蜗杆传动二次包络理论及鼓形蜗杆刀具齿面数学模型。分析内渐开包络母面重现的必然性及内齿轮加工共轭关系。研究鼓形蜗杆刀具齿面的轴向齿形特性及齿面根切规律,并给出刀具齿面根切的避免方法。应用虚拟中心距原理分析鼓形蜗杆刀具的粗加工工艺参数优化方法及其精确加工原理。该研究工作为内齿轮的高效高精加工提供了一种有效途径。
Aiming at the disadvantage of current internal gear manufacturing method, a continuous generating method for internal gear with crown worm cutter is presented. Based on the theories of differential geometry and gear mesh, the secondary action principle of crown worm driving and the mathematical model of crown worm cutter are established. The necessity for the reproduction of internal involute generating surface and the conjugate relationship of internal gear processing are also analyzed. The tooth profile of the crown worm cutter is studied, namely to analyze the law of the parameters on tooth undercutting, and the approach to avoid the tooth undercutting is provided. The rough processing parameter optimization methodology and precise processing principle are analyzed based on the principle of virtual center distance. The studies supply an effective and precise approach to process internal gears.
