20. DESIGN AND ANALYSIS OF 3- STAGE EPICYCLIC GEAR BOX FOR AIRCRAFT APPLICATION

Planetary Gear System is an assembly of gears where one or more planet gears revolve around a gear put at focus named Sun gear and a ring gear circles the entire framework. It is fit for accomplishing high decrease proportions in an extremely minimal bundle. Huge number of assembling mistakes can impact the anxieties actuated onto the stuff framework. In this paper, a nitty gritty investigation of the plan of a planetary gearbox is done from the start. In the wake of planning, this exploration uses the limited component technique to research the variety of stresses happening because of misalignments. Here, the anxieties analyzed are occurring due to misalignments resulting from the tolerances on center distance bet ween gears and also from the tolerances on parts. In this paper, we have reviewed the research papers mainly dealing with the designing and analysis of a planetary gearbox.
