Piñonario: From Chain Specs to a Cut-Ready Sprocket
A Spanish-language calculator turns chain standard, pitch, and tooth count into sprocket dimensions, workshop measurements, and a downloadable DXF profile.
- For
- Machinists and power-transmission designers
- Worth noticing
- The DXF option includes separate reference circles for pitch and root diameters, and specifies an ISO 606 profile with exact arcs.
Field notes
The input flow separates chain standard, pitch, tooth count, strand count, and units, then groups results into diameters, measurement checks, tooth profile, hub, and material. Its sample 08B output includes rod-measurement data and estimated stock and finished-part weights. A caution says to check dimensions against the real chain because manufacturers may use different tolerances; the page also links the calculator to workshop fabrication examples.
