### 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.

By input we understand the source of power, in our case could be an electric motor. By output we mean where the power is delivered ( hydraulic pump). The gear ratio i can be calculated in two ways: as a ratio between the number of teeth of the output gear and the number of teeth of the input gear [i=frac{z_{OUT}}{z_{IN}}]
