本文提出了一种新的双作用环面蜗杆副的结构形式,其特点是蜗轮齿面上的一次二次作用面是分开的,从而使蜗轮副分度面的形成原理及外形都产生了很大的变革.本文分析了这种新型蜗轮副的设计原理及接触润滑特性,结果表明,它不仅能克服传统的双作用环面蜗杆副在润滑及油膜承载能力方面的缺点,而且具有一系列优点,如可以压缩蜗杆副的中心距;能使作用在蜗杆上的大部分径向力相互抵消;显著地提高了刚度等.这些优点使这种新结构特别适用于高速重载传动.
This paper presents a new double-acting toroidal worm deputy structure, which is characterized by a worm gear tooth surface is a secondary role of the surface is divided, so that the formation of worm gear sub-surface principle and appearance have produced a very Great changes.This paper analyzes the design principle and contact lubrication characteristics of the new worm gear pair.The results show that it not only overcomes the shortcomings of traditional double-acting toroidal worm pairs in lubrication and film bearing capacity, but also has a series of advantages , Such as centering the worm pairs, enabling most of the radial forces acting on the worm to cancel each other, significantly increasing the stiffness, etc. These advantages make the new structure particularly suitable for high-speed heavy-duty transmissions.
