Belt Tension Calculator vs Pulley Speed Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Belt Tension Calculator
Find the tight-side tension required in a belt drive to transmit a given power at a known belt speed. Use it when designing V-belt or flat-belt systems to size belts, pulleys, and shafts correctly.
- Answers
- Tight Side Tension (N)
- Inputs
- Transmitted Power, Belt Speed, Wrap Angle, Belt Type
Pulley Speed Calculator
Calculates the output shaft speed of a belt-and-pulley system based on pulley diameters and input speed. Use it when designing drive systems to achieve a target RPM ratio between driver and driven shafts.
- Answers
- Output Speed (rpm)
- Inputs
- Input Speed, Input Pulley Diameter, Output Pulley Diameter
