球面蜗轮副因其体积小、重量轻、承载能力大,而在重型机械等的各类机械的传动中得到了广泛的应用。球面蜗轮副最重要的优点,是它的瞬时接触线和齿面接触处综合曲率半径较大,很有利于油楔的形成和保持。但是,至今对它的啮合原理和传动的流体动力学的研究仍是不充分的。本文想就目前国内外能收集到的 Spherical worm gear because of its small size, light weight, carrying capacity, but in the heavy machinery and other types of mechanical transmission has been widely used. The most important advantage of the spherical worm gear is that its instantaneous contact line and the contact area of ​​the tooth face have a large overall radius of curvature, which is very conducive to the formation and maintenance of the oil wedge. However, the research of the meshing principle and the hydrodynamics of the transmission till now has not been enough. This article would like to collect at home and abroad
