Design procedure for flat belt

Requried data

Power to be trancemited

Input and output of the shaft speed

Center distance between pully

Step:1 Calculation of pully diameter

By using belt speed,assuming number of belt the minimum pully

diameter is choosen from PSG design data book (page number 7.54)

Step:2 Calculation of design power in kw

Design=(Rated(kw) x load correction factor(ks))/(Arc of contact factory x

small pully factor (kd))

From PSG Design data book (page number:7.53,7.54 and 7.62) the

values of ks ,kd is found respective

Step:3 Selecton of bending:

The type of belt is selected from PSG data book page number:7.54

Step:4 Load correcton factor:

Load ratting at V m/s =(load rating 10 m/s x (v/10))

V =(d1N1)/60

Step:5:Determination of belt width

Width of the belt =(design power is kw/(load rating x no of plies)

From PSG design data bookn pg.no.7.52 standard width of belt is

selected

Step:6: Determination of pully width

From PSG data book pg no 7.54,7.55 the pully width is selected

Step:7:Calculation of belt length

Open belt drive:

L=2c+(/2)+(D+d)+((D-d)2/4c)
