2 kW of power will be trasnmitted via chain-sprocket system.Rotational speed of input shaft is 20 rpm. Required approximaterotational speed of input shaft is 20 rpm. Required approximaterotational speed for the out shaft is 7 rpm. Approximate distancebetween center lines of input and output shafts should be 900 mm.This chain-sprocket system is used for an elevator and it is askedto use single or multiple DIN 8187 chain with 31.75 mm pitch.
a) Calculate number of teeth on sprocket, which is on outputshaft, is number of teeth on the sprocket on input shaft is 19.
b) Calculate input power for selection of chain and select theappropriate chain type.
c) Calculate pitch circle diameters of driving and drivensprockets, linear velocity of chain, length of chain, (number ofchain links), and exact center line distance between driving anddriven sprocket.
d) Calculate factor of safety of the selected chain.
