What is a belt drive used for?

Belt drive, in machinery, a pair of pulleys attached to usually parallel shafts and connected by an encircling flexible belt (band) that can serve to transmit and modify rotary motion from one shaft to the other.

Difference Between Open Belt Drive and Cross Belt Drive?

In open belt drive, driving shaft and driven shaft rotate in same direction. In crossed belt drive, driving shaft and driven shaft rotate in opposite direction.

How to Calculate Length of an open belt drive?

Length of an open belt drive calculator uses Total length of the belt=pi*(Radii of the smaller pulley+Radii of the larger pulley)+(2*Distance between the centers of two pulleys)+(((Radii of the larger pulley-Radii of the smaller pulley)^2)/Distance between the centers of two pulleys) to calculate the Total length of the belt, Length of an open belt drive is based on two factors: the center-to-center distance between pulleys and the arc of contact between the belt and the pulleys, which depends on the relative pulley diameters. Total length of the belt and is denoted by L symbol.

How to calculate Length of an open belt drive using this online calculator? To use this online calculator for Length of an open belt drive, enter Distance between the centers of two pulleys (x), Radii of the smaller pulley (r2) and Radii of the larger pulley (r1) and hit the calculate button. Here is how the Length of an open belt drive calculation can be explained with given input values -> 63.46548 = pi*(6+10)+(2*5)+(((10-6)^2)/5).

FAQ

What is Length of an open belt drive?
Length of an open belt drive is based on two factors: the center-to-center distance between pulleys and the arc of contact between the belt and the pulleys, which depends on the relative pulley diameters and is represented as L=pi*(r2+r1)+(2*x)+(((r1-r2)^2)/x) or Total length of the belt=pi*(Radii of the smaller pulley+Radii of the larger pulley)+(2*Distance between the centers of two pulleys)+(((Radii of the larger pulley-Radii of the smaller pulley)^2)/Distance between the centers of two pulleys). Distance between the centers of two pulleys is the horizontal distance between larger and smaller pulley, Radii of the smaller pulley is a straight line from the center to the circumference of pulley and Radii of the larger pulley is a straight line from the center to the circumference of pulley.
How to calculate Length of an open belt drive?
Length of an open belt drive is based on two factors: the center-to-center distance between pulleys and the arc of contact between the belt and the pulleys, which depends on the relative pulley diameters is calculated using Total length of the belt=pi*(Radii of the smaller pulley+Radii of the larger pulley)+(2*Distance between the centers of two pulleys)+(((Radii of the larger pulley-Radii of the smaller pulley)^2)/Distance between the centers of two pulleys). To calculate Length of an open belt drive, you need Distance between the centers of two pulleys (x), Radii of the smaller pulley (r2) and Radii of the larger pulley (r1). With our tool, you need to enter the respective value for Distance between the centers of two pulleys, Radii of the smaller pulley and Radii of the larger pulley and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Total length of the belt?
In this formula, Total length of the belt uses Distance between the centers of two pulleys, Radii of the smaller pulley and Radii of the larger pulley. We can use 1 other way(s) to calculate the same, which is/are as follows -
