Iff ear-trailis with filultiple gears wife fallo will Chialige ffolli set to set. If there are two sets of gears off a given shaft, both spin at the same RPM. The ratio from gear set to gear set is calculated separately then multiplied together. Example: A has 8 teeth; B has 36 teeth; the ratio for the A:B is 9:2. B*# has 8 teeth; C has 60; the ratio for B*#:C is 15:2. Multiply 9:2 x 15:2. The net gear ratio is 9135:4 C B RATIO HOW MANY TIMES A= 10; B=20; B**= 5;C=10 If A turns one time, C will turn A= 10; B=40; B**= 5; C=5 If A turns one time, C will turn A= 36; B=12; B**= 36; C=3 If C turns one time, A will turn A= 10; B=60; B**= 5; C=60 If B turns one time, C will turn A= 12; B=48; B**= 8; C=6 If A turns one time, C will turn
