Q1. A spur gear train with a speed reduction of 3:1 is to be used in a sugarcane crusher. A single cylinder petrol engine running at 720 rpm drives the input gear and supplies (Q+5) kW power. Medium shocks are involved in sugarcane crusher. Calculate the module and specify all dimensions of the gears. The pinion is made of steel (Sut = 750 MPa) & gear is made of cast iron (Sut = 450 MPa). Both gear and pinion are having a surface hardness of 350 BHN. Both gear & pinion are having involute teeth with 20° pressure angle. Use a factor of safety of 2.
