Assignment Help Mechanical Engineering
Reference no: EM13906491

You are to design a Flat pulley drive for a refrigeration system with the compressor pulley diameter being 450mm and the motor pulley diameter being 200mm. The two shafts will be 1.95m apart and connected to a closed belt. Find

a. The angle of contact /angle of lap for the two pulleys.

b. Find the required length of belt.

c. Select a suitable belt and, ignoring the elongation at fitting but using the guide mass/unit length, calculate the power transmitted if the maximum permissible tension is 1kN and the coefficient of friction is 0.25 if the motor rotates at 1450rpm.

d. Also find the minimum initial tension require at commissioning stage.
