... prevent premature failure of gears, extend their service life, reduce power losses and improve transmission efficiency. Design/methodology/approach This study addresses issues such as the unclear lubrication mechanism and inability to accurately predict transmission efficiency in the oil churning...

... on the transmission efficiency. Design/methodology/approach A mathematical model of transmission efficiency was established, and the efficiency of transmission was studied by means of numerical analysis. Findings The results demonstrate that the transmission efficiency decreases with the thickness of the oil...
