【摘要】 具有蜗轮偏转角的圆柱滚子包络内啮合蜗杆是一种新型的能实现多负载和不同角度输出的蜗杆副,分析蜗轮偏转角对潜在的根切现象和圆柱滚子自转性的影响,对深入了解该传动装置具有重要意义。利用一界曲线方程和自转角公式分别对其根切现象和自转性能进行分析,得出当蜗轮偏转角大于等于44°时,该装置将会发生根切;同时蜗轮偏转角越大,其蜗轮轮齿的自转性能越差,并且发现蜗轮轮齿上的接触线曲率越大,其自转性能越差。该研究给蜗轮偏转角的选取提供了参考。更多还原

【Abstract】 The cylindrical roller enveloping end-face internal engagement worm gear with the worm-wheel rotational deflection is a novel transmission that can achieve multi-load and different corner angular outputs. Analysis of the effect of the worm gear deflection angle on potential root-cutting and rotation of performance is important for understanding the device. The analysis of root-cutting and performance of rotation is carried out by using boundary curve equation and rotational formula. The study indicates that the worm-wheel rotational deflection angle that is equal or larger than 44° has occurred undercutting,and the performance of rotation is degraded with the increase in wheel rotational angle; at the same time,performance of rotation is degraded with the increase in the curvature of the contact line on the cylindrical roller. The study provides a reference for the selection of the worm-wheel rotational deflection of this new driving.更多还原
