环面蜗杆传动因其多齿啮合特性而具有承载能力强等优势,但其约束数相应增加,对制造误差及装配误差更为敏感。为降低重载环面蜗杆传动的误差敏感性,提出了一种修正型渐开线齿轮包络环面蜗杆传动。构建渐开线齿轮与媒介齿轮及环面蜗杆三者之间的啮合几何学模型,建立了传动副空间点接触局部共轭接触分析方法;通过数值分析及有限元仿真分析,揭示了修正型渐开线齿轮包络环面蜗杆传动啮合特性的变化规律。结果表明,该新型环面蜗杆传动具有较低的误差敏感性,同时保持了高载荷下的承载能力。针对某人机交互7 000 m自动化钻机重载机器人回转关节,研制了修正型渐开线包络环面蜗杆传动减速器样机,并进行了相关性能试验,验证了理论分析的准确性。
Due to the characteristics of multi-tooth line contact
toroidal involute worm drive has the advantages of high bearing capacity and so on. However
due to increased constraints
it is more sensitive to manufacturing error and assembly error. To reduce the error sensitivity
this study proposes a modified toroidal involute worm drive based on the medium gear. The meshing geometry model between involute gears
medium gears and toroidal worms is constructed
and the local conjugate contact analysis method of space points of the drive pair is established. The spatial point-contact analysis method is developed
combined with numerical analysis and finite element simulation analysis
and the variation principles of meshing characteristics are revealed.The results show that the novel toroidal worm drive has lower error sensitivity
and can maintain the bearing capacity under high load. Based on a man-machine interactive heavy-duty robot rotary joint applied to 7 km automatic drilling rigs
a prototype of modified involute enveloping toroidal worm drive reducers is developed
and the correctness of theoretical analysis is verified.
