compound epicyclic gear train.
The Fig. shows the arrangement of wheels in a compound epicyclic gear train. The sun wheel S₂ is integral with the annular wheel A₁. The two arms are also integral with each other. The number of teeth on the wheels are as follows: S₁=24, A₁=96, S₂=30, A₂ = 90If the shaft P rotates at 1980 r.p.m., find the speed of the shaft Q, when A₂ is fixed At what speed does Q rotate, when A₂ instead of being fixed, rotates...

Answer given is No=-143rpm (in opposite direction to A)
A compound epicyclic gear is as shown in Figure 4.9. Ai and S2 form a compound wheel, which rotates freely on shaft O. The Planet wheels P1 and P2 rotate on pins fixed in arms attached to shaft O. and A2 have internal teeth: the others have external teeth, with the following numbers, tsi=40; tp1=30 ; tpz=20; ts2=50. If Si rotates at 500 rpm and wheel Az is fixed, find the...
