The input gear has 22 teeth on it and the output gear has 45 teeth on it. what’s the reduction ratio? a. 3.3: 1 b. 4: 1 c. 2: 1 d. 3: 1

Solution:

Number of teeth on input gear= 22 teeth

Number of teeth on output gear= 45 teeth

Reduction=Number of teeth on output gear - Number of teeth on input gear

                 = 45 - 22

                  = 23

Reduction Ratio=(Number of teeth on output gear) / (Reduction)

→→Option C. 2: 1 is true.
