The
gear ratio of mating gears is defined as the ratio of
Number
of teeth on gear to that on pinion
Number
of teeth on pinion to that on gear
Number
of teeth on gear to the diameter of gear profile
None of these
Number
of teeth on gear to that on pinion
Gear
ratio (G) : It is the ratio of the number of teeth on the gear (T) to that on
the pinion (t)
Mathematically,
Where,
T = Number of teeth on gear
t = Number of teeth on pinion
Hence,
the correct option is (A).
