Standard of curvature and shape of drums and pulleys for conveyor and flat belts

 

 

 

 

 

Shape of conical rollers for guiding conveyor belts

Shape of conical rollers for guiding conveyor belts  

b = drum width

bc = width of the cylindrical part

bo = band width

of = outside diameter

e = conicity

 

Calculating the drum width:

b = 1.1 x bo + 10 (mm)

Calculating conicity :

e = (from + 100) / 500 (mm)

Calculation of the cylindrical part in relation to the total width of the drum :

bc = b / 2

 

Curved pulley shape for power transmission belts with a polyamide core

To calculate the radius of curvature of the pulleys, apply the following formulae:

Curved radius of polyamide flat power transmission belts

Pulley Diameter Crown height h

up to 112 0.3
over 112       up to 140 0.4
over 140       up to 180 0.5
over 180       up to 224 0.6
over 224       up to 355 0.8
over 355       up to 500 1
over 500       up to 1000 1.2
