Copulatio est series duarum rotarum dentatarum ad copulationem et duorum filorum catenarum. Foramen axis cuiusque rotae dentatae tractari potest, quo fit ut haec copulatio flexibilis, facile instituatur, et in transmissione valde efficax sit.
Characteres:
1. Magnitudo compacta, efficacia transmissionis altior quam aliae copulae, efficacia sumptuum
2. Facile tractatu et centro collocatione
3. Ambitui operandi valde resistens cum longa vita
4. Spatium inter rotam dentatam et catenam transmissionem flexibilem permittit.
Numerus copulationis: 3012, 4012, 4014, 4016, 5014, 5016, 5018, 6018, 6020, 6022, 8018, 8020, 8022, 10020, 12018, 12022
