vitesse de sortie: tr/ min entre*R
vitesse entree*rapport de reducteur

vitesse dentree: vitesse de sortie /rapport de reducteur

rapport de reduction: 
  roue menante/roue menee
  
  
rendement global=nmenantes* nmenees

rendement=putile/pabsorbée

n=n1*n2*n3*n4*n5....

reducteur de vitesse: (tr/min)s<(tr/min)e
(tr/min)s=R*(tr/min)e

* de vitesse:(tr/min)s>(tr/min)e
(tr/min)s=R*(tr/min)e

poulie/couroie: N2/N1= d1/d2

roue dentees:
N2/N1=Z1 (nbr de dents)/Z2(nbr de dents)
