What is efficiency of spur gear?
Spur Gear Efficiency Spur gearing is a parallel shaft arrangement, and these gears can achieve much higher efficiencies compared to other gears types. Its efficiency varies from 94% to 98% with lower gears ratios.
How is gear ratio calculated?
To calculate the gear ratio: Divide the number of driven gear teeth by the number of drive gear teeth. In our example, it’s 28/21 or 4 : 3. This gear ratio shows that the smaller driver gear must turn 1,3 times to get the larger driven gear to make one complete turn.

What is the formula for gears?
The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).
