What the four calculators do
- Rack and pinion — feed force, speed and drive torque from mass, acceleration, friction and the pinion geometry.
- Gearbox efficiency — overall efficiency of multi-stage drive trains from the efficiencies of the individual stages.
- Ball screw — sizing by lead, load and speed.
- Magnetic coupling — design by transmissible torque and containment shell situation.
That brings the tool collection to thirteen calculators.
Verified calculation paths, not quick rules of thumb
Behind these four calculators sits a stored reference implementation that is checked against fixed test vectors. If a formula changes, the deviation shows up before it goes live.
Just as important to us is where the calculators reach their limits: they say so explicitly when an assumption no longer holds — for instance with profile shift or helical gearing. A preliminary calculation does not replace a binding one, and we do not pretend otherwise.
The theoretical background sits in the matching guides, linked from each calculator.
