Research on the influence of rolling cone parameters on the relative sliding velocity on the contact line of rolling cone enveloping hourglass worm pair

Abstract：To study the rotational angular velocity of the rolling cone and the relative sliding velocity on the contact line during the work process of rolling cone enveloping hourglass worm pair, the positive pressure of the rolling cone tooth surface was distributed to every discrete point on the contact line based on the force characteristics.The relative sliding velocity of every discrete point on the contact line was obtained by using the numerical calculation software, and the influence of rolling cone tip radius and rolling cone angle on the relative sliding speed were analyzed.The results showed that the self-rotation of the rolling cone could significantly reduce the relative sliding speed between the meshing tooth surfaces, and the two parameters which included the rolling cone tip radius and the rolling cone angle could be optimized, so as to make the relative sliding speed of the meshing tooth surfaces the least.This layed a theoretical foundation for further research on the transmission efficiency of worm gear pair.
