How to calculate the gear ratio of the reducer

CalculationReducerThe gear ratio method:

1. In a pair of gears, the gear with a small number of teeth is called a pinion, and the gear with a large number of teeth is called a large gear. When the number of teeth is the same, the driving gear is called a pinion, and the driven gear is called a large gear;

2. In a pair of external gears, the rotation is reversed for you, the small gear rotates to the right, and the large gear rotates to the left;

3. In a pair of internal gears, the two gears run in the same direction;

4. In a pair of gears, the number of revolutions and the number of teeth are inversely proportional, the number of revolutions of the pinion is more than that of the large gear, and the ratio of the number of teeth and the gear ratio of the reducer are as follows: Number of teeth ratio ⅰ = number of teeth of the large gear/number of teeth of the pinion; worm nut Gear: Gear ratio ⅰ = number of worm gear teeth / number of worm bars.
