Gears, Velocity Ratios and Mechanical Advantage
not easy to estimate; it depends on many factors, including the torque and speed, the tension of the belt, the friction between the belt and the pulley, and the elasticity of the belt. • The rule with pulleys is that the reduction ratio is determined by the ratio between their diameters.

Gear ratios and compound gear ratios
Gear ratios and compound gear ratios. Working out simple gear ratios (two gears) A feature often requested in my gear program is that it should calculate and display the gear ratio.. The reason it does not have this feature is that the gear ratio is also the tooth count ratio (of the two gears), and that is a value that the user has to enter.

Calculation of reduction ratio in crushing [image: (13553)] Crushing Equipment. The selection of the right crushing equipment is influenced by many factors some of which are upstream of the crushing plant ( blasting pattern and mining method) and others which are downstream of the crushing plant ( mill and grinding circuit selection).

How to calculate reduction ratio  eHow UK
· Calculate the reduction ratio by dividing output torque by input torque. If 50 footpounds on the output results from 10 footpounds on the input, the reduction ratio is 5 to 1. This is similar to counting gear teeth. In that case, a 42tooth gear driven by a 14tooth gear calculates to 42/14, or a 3to1 reduction ratio.

How to Calculate Percentage Reduction  Sciencing
· The formula for finding the percentage of reduction is: P = a / b × 100. Where P is the percentage of reduction, a is the amount of the reduction and b is the original amount that was reduced. Subtract the final amount from the initial amount to find the amount of the reduction. For example, if your salary was 59,000 and it was reduced to ...

Mechanical Gear Reduction Calculator
Output Speed = Input Speed / Ratio of Gear Reduction. Example: A gear reducer with 1000 in/lbs of input torque, an input speed of 2000 RPM, and a reduction ratio of :1 is: Output Torque = 1000 x Output RPM = 2000 / Calculated out this gives an output torque of 3,500 in/lbs and an output speed of RPM.
