Abstract
The contact and kinematic conditions of a helical gear pair vary along the contact line and change continuously during the meshing cycle. The paper presents a transient elastohydrodynamic lubrication (EHL) analysis of this situation to evaluate the characteristics of the oil film separating the tooth surfaces under loaded conditions. In the analysis the load on each of the overlapping tooth contacts is varied according to the total instantaneous contact line length. Results are presented that reveal the practically important effects of different forms of tip relief and axial profile modification (crowning) on the contact stresses and film profiles. The results are compared with those obtained from equivalent quasi-static analyses at different positions in the meshing cycle.
