OPTIMIZATION OF RAVIGNEAUX PLANETARY GEAR SET
, 2018 The advancement of the automotive industry tended to replace classical gears with fixed axes, withplanetary gear set with movable axes. Planetary gear sets have many advantages over classical gears, but theirdesign is more complex. One of the planetary gear sets, which is highly applicable in the automotive industry,is the Ravigneaux planetary gear set.
