4.1 MAXIMUM POWER WITH NO BELT SLIP. The power transmitted by a pulley was shown to be P = πND (F1 - F2) = v(F1 - F2) When the belt starts to slip the force ratio is (F1 /F2) = eµθ Substituting for F2 we have P = πNDF1(1 -e -µθ) It may be easier to use belt velocity instead of wheel speed. v = πND P = v F1(1 -e-µθ)

10/14 · What is belt drive? A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently, or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel.

Design of v belt drives complete notes ebook free download pdf V-belt drives are most recommended for shorter center distances. In comparison to flat belt drives, these drives are slightly less efficient. V belt can have transmission ratio up to 1:15 and belt slip is very small. As the belts are endless type, V-belt drives do not suffer
