Název v původním jazyce

A study of hydrodynamically lubricated contact between axial rings of a high-speed gearbox

Popis výsledku v původním jazyce

The pressure field and losses in hydrodynamically lubricated contact between axial rings of the pinion and the wheel of a high-speed gearbox under steady-state loading are investigated. For that reason a computer program was developed to numerically solve the general Reynolds and energy equations simultaneously, with consideration of a viscosity-temperature relation. The Barus’ empirical equation was used to express a viscosity-pressure relation as well. For chosen design parameters, dissipative heat in the lubricated contact is shown as a function of transmitted axial force. It is presented that the contact axial force and losses are influenced by the state how the gap between rings is filled.
