( Use of P S G Design Data Book permitted )

UNIT I DESIGN OF FLEXIBLE ELEMENTS 

Design of Flat belts and pulleys – Selection of V belts and pulleys – Selection of hoisting wire ropes
and pulleys – Design of Transmission chains and Sprockets.

UNIT II SPUR GEARS AND PARALLEL AXIS HELICAL GEARS 

Speed ratios and number of teeth-Force analysis -Tooth stresses – Dynamic effects – Fatigue strength
– Factor of safety – Gear materials – Design of straight tooth spur & helical gears based on strength
and wear considerations – Pressure angle in the normal and transverse plane- Equivalent number of
teeth-forces for helical gears.
