ABSTRACT:
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. In the calculation, the housing is taken as the reference
system and the influence of the housing’s rotating on the lubrication is
ignored. Film pressure, film thickness and temperature rise are
analyzed under maximum load condition. This research provides some
approximate reference data for the design of lubrication and cooling system of
PSD.
