Abstract

Toroidal involute worm (TI worm) exhibits high load-bearing capacity and transmission efficiency. However, its complex spatial geometry complicates machining processes and limits mass production. This study combines the enveloping principle of the TI worm with the internal whirling technique. A novel method is developed for enveloping the TI worm via internal whirling. The influence of tool offsets and mounting angles on the tooth surface deviations between internal whirling-enveloped TI worm and standard TI worm is investigated. The results indicate that the tooth surface of the internal whirling-enveloped TI worm closely approximates that of modified standard TI worm. The amount and position of the modification can be effectively controlled through tool offset and mounting angle adjustments. Experimental measurements reveal a maximum tooth surface deviation below 0.04 mm. The machined worm meshes in the middle of the involute helical gear, reducing offset load risks. Comparative tests confirm comparable transmission performance between machined worm and standard TI worm. This study establishes theoretical and experimental foundations for mass production of TI worm via internal whirling to meet industrial demands.

内旋包络TI蜗杆齿面偏差的研究

环面渐开线蜗杆具有较高的承载能力和传动效率。然而，其复杂的空间几何形状使加工过程复杂化，限制了批量生产。本研究将TI蜗杆的包络原理与内旋技术相结合。提出了一种利用内旋包络TI蜗杆的新方法。研究了刀具偏移量和安装角度对内旋包络TI蜗杆与标准TI蜗杆齿面偏差的影响。结果表明，内旋包络TI蜗杆的齿面与改进的标准TI蜗杆齿面非常接近。通过调整刀具偏移和安装角度，可以有效地控制修正量和位置。实验测量显示，最大齿面偏差小于0.04 mm。加工后的蜗杆啮合在渐开线斜齿轮的中间，减少了偏置负载的风险。对比试验证实，加工蜗杆与标准TI蜗杆的传动性能相当。本研究为大规模生产TI内旋蜗杆以满足工业需求奠定了理论和实验基础。
