1. Machine Element Design Design of Belts and Chains

2. Design of Classical V-belts Classical V belts cross sections

3. Design of V-belts  Calculation of design horse power  Design horse power=trainsmitted horse power(given)*S.F  Selection of belt type  Calculation of pulleys dimensions and center distance  Calculation of horse power rating according to belt type  Correcting the horse power rating  Calculating the number of required belt rows

13. Design of chains and Sprockets Roller chain Parts

14. Sprocket Dimensions  A Sprocket has three diameters:  Inner diameter  Outer diameter  Pitch diameter=P/sin(180/N)  Sprocket Parameters:  Pitch(P)  Number of Teeth(N)  chain parameter  Chain pitch(P)

15. Types of Sprockets

16. Selection of Service factor Design horse power=trainsmitted horse power(given)*S.F

17. Selection of Sprocket Type and Pitch based on horse power and speed of small sprocket

18. Roller Chain Dimensions(according to selected pitch)

19. Calculation of Center Distance and number of chain links  C: center distance  P: chain Pitch  L:chain length  N 1 : Number of small sprocket Teeth  N 2 : Number of largesprocket Teeth  d p : Pitch diameter of small sprocket  D p : Pitch diameter of large sprocket
