Question

A gear wheel having 80 teeth is in mesh with a 25 tooth gear. What is the gear ratio?

Answer 1

or perhaps the other way around, 80/25

Answer 2

The gear ratio can be found by dividing the number of teeth on the driven gear (25) by the number of teeth on the driving gear (80).

Gear Ratio = Number of teeth on driven gear / Number of teeth on driving gear
= 25 / 80
= 0.3125

Therefore, the gear ratio is 0.3125 or 31.25%.

Answer 3

Apologies for the confusion. You are correct.

The gear ratio is found by dividing the number of teeth on the driving gear (80) by the number of teeth on the driven gear (25).

Gear Ratio = Number of teeth on driving gear / Number of teeth on driven gear
= 80 / 25
= 3.2

Therefore, the gear ratio is 3.2.
