The amount a gear system can alter rotational speed is a function of the relative sizes of the gear wheels, and it's known as the gear ratio. The gear ratio formula turns out to be fairly simple. You basically count the number of teeth on the driven wheel and divide that by the numbe...
When calculating planetary or epicyclic gear ratios, first note the number of teeth on the sun and ring gears. Add them together to calculate the number of planetary gear teeth. Following this step, the gear ratio is calculated by dividing the number of driven teeth by the number of driving ...
In general, though, a higher inventory turnover ratio is better than a lower one. A ratio of 2 or above is usually considered good. A ratio of 4 or above is usually considered excellent. There are a few exceptions to this rule. If your company sells products with a long shelf life, ...
