UNIT 3 POWER TRANSMISSION DEVICES Power ...
This can be used for transmission of speed at low power. Figure : Cross Belt Drive Since power transmitted by a belt drive is due to the friction, belt drive is subjected to slip and creep. Let d 1 and d 2 be the diameters of driving and driven pulleys, respectively. N 1 and N 2 be the corresponding speeds of driving and driven pulleys, respectively. The velocity of the belt .
