Planetary Gear Fatigue Behavior in Automatic Transmission

SAE Technical Paper Series, 2006
<div class="htmlview paragraph">An automatic transmission planetary gear fatigue test is used to screen lubricant performance of various automatic transmission fluids. The key use of this test is to assess the ability of a lubricant to extend or limit planetary gear system fatigue life.

Deformability of elements of a planetary gear transmission

Russian Engineering Research, 2010
An analytical method is outlined for determining the stress state of the pole and satellite shaft in a planetary gear transmission within their contact zone. The influence of these elements on the pliability of the joint and on the directional error of the satellite shaft is established. Measures are proposed for equalizing the loads in the couplings.
