Abstract:
In this paper, transient EHL equations considering vibration effects of
gear transmission system and its evaluation have been given. In research
of transient EHL, transient effects of variable load, variable curvature
radius and variable rolling veloiety are combined and have been used to
lubrication problem of involute spur gears. Where, the variable load is
the dynamic load caused by vibration of gear transmission system which
is solved by numerical method with a model of eight-masses and
sixteen-degrees of freedom. The vibrant-transient EHL problem of each
meshing point along the meshing line is considered as a time procedure
and the full numerical solution has been made. One example of the
numerical solution is given. The pressure spike and the minimum film
thickness varying along the meshing line, as well as the pressure
distribution and film shape of seven special meshing points are shown in
figures.
