In the fabric dye-printing system given in the figure, the motion is transmitted from the electric motor to the drum of the machine. There is a two-stage reducer in between. Number of teeth of gears z1=17; z2=85; z3=18; z4=72; The efficiency of a pair of gears is given as na=0.97 and the efficiency of each of the gearbox shafts and lower bearing pairs to the drum bearing is given as n=0.97. The diameter of the drum will be D=200 mm, the fabric speed will be v=1 m/s and the pulling force required to activate the band will be taken as F-2000 N. a) Find the number of revolutions of the engine. b) Find the required engine power.
