degree of rotation of A2 / degree of rotation of A1 = 1/Gear ratio = 40/82 __________________ eq.1
=> Degree of rotation of A2 = 10*40/82 = 4.878 degrees ________________________ Answer
A1 (driving gear) has 40 teeth and A2 (driven gear) has 82 teeth. If A1 rotates...

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...
