Design Calculators - Mechanical

This calculator determines the speed ratio and unknown parameters (speed, diameter, or number of teeth) for belt and pulley, or chain and sprocket drive systems. It's essential for designing and analyzing power transmission systems.

Key Inputs:

• Unit System: Select Metric (mm, RPM) or Imperial (inch, RPM) for measurements.
• Drive Type: Choose 'Belt/Pulley' (uses diameters) or 'Chain/Gear' (uses number of teeth).
• Calculation Mode: Select which parameter you want to calculate (e.g., Driven Speed, Driver Diameter).
• Driver Diameter (\(D_{driver}\)) / Teeth (\(T_{driver}\)): Diameter of the driving pulley/sprocket or number of teeth on the driving gear.
• Driven Diameter (\(D_{driven}\)) / Teeth (\(T_{driven}\)): Diameter of the driven pulley/sprocket or number of teeth on the driven gear.
• Driver Speed (\(N_{driver}\)): Rotational speed of the driving shaft (e.g., motor speed).
• Driven Speed (\(N_{driven}\)): Rotational speed of the driven shaft.

Calculated Outputs:

• Speed Ratio ((\(i\)) or (\(SR\))): The ratio of driver speed to driven speed, or driven diameter/teeth to driver diameter/teeth.
• Calculated Parameter: The value of the unknown parameter based on the selected calculation mode.
