Gear Ratio Calculator: Mechanical Drive & Transmission Tool

    Created by Md jony islam

    Simple gear calculator

    Calculate gear ratios and speed relationships between driving and driven gears. Get instant ratio measurements with tooth count inputs. Engineers use the gear ratio calculator to identify how driving element speed relates to torque generation in mechanical systems with driving and driven gears. Currently the transmission calculator allows input of gear teeth values or diameters to produce gear ratio and speed outputs. The gear ratio calculator determines accurate mechanical advantage relationships together with ratio outputs to support power transmission work in all areas of engineering, including mechanical devices and automobiles.

    Additional Information

    • Gear ratio is the relationship between the number of teeth on two gears that are meshed together.
    • Formula: Gear Ratio = Driven Teeth ÷ Driving Teeth
    • The ratio determines the speed and torque relationship between the gears.
