V-BELT DRIVES

• Introduction to V-belts and wedge belts - belts versus gears, types of belt, standard pitch lengths and commercial pulleys
• Geometry of a drive - centre distance and belt length
• Kinetics of a belt on a pulley - tension ratio, effect of pulley diameter, centrifugal effects
• Fatigue of belt in double- peaked cycle - belt drive design equation, effect of pulley size and belt number on fatigue life
• Effectiveness of fatigue life usage
• Belt drive selection - duty factor, selection steps
• Drive selection using the tabular approach of codes and commercial literature
• Special drives - V-flat and pivoted motor drives
• Traction mechanics - a more realistic model which recognises belt / pulley adhesion and initial tension.
