Unveiling the 48:16 Gear Ratio

What is a Gear Ratio?

Before we delve into the specifics of the 48:16 gear ratio, it’s essential to grasp the concept of gear ratios in general. In simple terms, a gear ratio is a numerical representation of the relationship between the number of teeth on two intermeshing gears. It indicates how many times one gear will rotate in comparison to the other gear.

Decoding the 48:16 Gear Ratio

The 48:16 gear ratio refers to a gear system where the driving gear, or the gear connected to the power source, has 48 teeth, while the driven gear, which receives power from the driving gear, has 16 teeth. In this configuration, for every revolution of the driving gear, the driven gear completes three revolutions.
