The under given diagrams provide guidelines for selection of belt section with in the selected type of V-belts. It is often appropriate to make calculations with a different section. In marginal cases we recommend our customers to select the closest smaller section, since it is our experience that this provides the consumer the given best solution, economically as well as technically.
From an overall point of view, we further recommend our customers to select the largest possible pulley diameter within the limits of the recommended maximum belt speed and the space available.
The under given Section selection diagrams are a function of the design power PD [kW] and the number of revolutions n1 [rev/min] of the smaller pulley
Design power P D = PM c1 [kW]
PM = Power consumption of the driven unit in kW or the rated kW of the driving unit.
c1 = Service factor
The belt section is found in the intersection of lines drawn from the design power PD in the left-hand side of the diagrams and the number of revolutions n1 on the bottom line. The pulley diameter dd [mm] corresponding to the recommended maximum belt speed is also shown here.
