Learn calculation for gear ratio. ... In the example, 3:1 gear ratio means that the driving gear has three teeth, and the driven gear has one tooth. How Does Gear Ratio Work? In a simple gear system, two gears with different numbers of teeth are meshed together. When the input gear rotates, it transfers its rotational energy to the output gear.

WhatsApp: +86 18221755073Calculating Gear Ratios. The formula for working out gear ratios is MA = (N1*N2*N3)/(n1*n2*n3). In this equation, N1, N2, and N3 are the teeth on the driving gears, and n1, n2, and n3 are the teeth on the driven gears. This lets designers pick the right gear setup for their project. They can aim for more force or more speed, as needed.

WhatsApp: +86 18221755073A planetary gear can also be used as a so-called direct drive. The carrier and the sun gear are firmly fixed to the ring gear. In this case, the rotary motion is transmitted directly from the input shaft to the output shaft (transmission ratio 1:1). Such a direct drive is used, for example, in three-speed gear hubs as the "2nd gear".
