Abstract In order to obtain a better driving mechanism of the differential pump, high-performance velocity vane pump was presented. The driven by novel eccentric non-circular gears. working principle and structure were studied. transmission high-order multisegment deformed gears established, then characteristics discussed. Finally an example given. showed that deformed, could meet large displac...

The paper briefly reviews Duncan Dowson's ground-breaking contribution to the theory of elastohydrodynamic lubrication in relation understanding gear tooth contacts. His early work with Higginson on numerical modelling finally explained how gears can operate successfully, and avoid wear, due generation a stiff, protective oil film. resulting minimum film thickness equation stands as reliable re...

Abstract To assess the meshing quality of spiral bevel gears, static characteristics are usually checked under different contact paths to simulate deviation in footprint from design point heel or toe gear flank caused by assembly error two axes. However, effect path on dynamics lubricated conditions has not been reported. In addition, most studies regarding gears disregard condition because com...

Abstract The alignment deviation of the V-vertex two symmetrically arranged gears with different rotation directions is a unique geometric parameter double helical gears, which has an important effect on vibration, noise, and gear service life. Aiming to more accurately represent manufacturing accuracy their transmission performance, this paper proposes meaning v-vertex basis contact line tooth...
