a) Calculate power lost in overcoming friction and the number of collars required for the thrust bearings whose contact surfaces are 20 cm external radius and 15 cm internal radius. The coefficient of friction is 0.08. The total axial load is 30 kN. The intensity of pressure is not to exceed 0.35 Mpa. The speed of the shaft is 420 rpm. b) Establish a formula for the frictional torque transmitted by a cone clutch. a) Calculate power lost in overcoming friction and the number of collars required for the thrust bearings whose contact surfaces are 20 cm external radius and 15 cm internal radius.
