Approximation Solution for TEHL of Bevel Gears in PSD
Journal of Applied Mathematics and Physics, 2013 To study the lubrication of the contact zone between half-shaft gears and planet gears in the power-split device (PSD), TEHL line contact of bevel gears in PSD is approximately computed based on a theory in which a bevel gear is equalized to an equivalent spur gear.
