class="w3-opacity">CONCEPTS DESIGN OF MACHINE MEMBERS– II Course Objectives: • This course gives the insight of slider and roller bearings and the life prediction. • Learn to design I.C engine parts • Design the mechanical systems for power transmission elements such as gears,belts,ropes,chains, keys and levers UNIT – I BEARINGS: Classification of bearings- applications, types of journal bearings – lubrication – bearing modulus – full and partial bearings – clearance ratio – heat dissipation of bearings, bearing materials – journal bearing design – ball and roller bearings – static loading of ball & roller bearings, bearing life. UNIT – II ENGINE PARTS: Connecting Rod: Thrust in connecting rod – stress due to whipping action on connecting rod ends – cranks and crank shafts, strength and proportions of over hung and center cranks – crank pins, crank shafts. Pistons, forces acting on piston – construction design and proportions of
