This formula uses 1 Functions, 4 Variables

Functions Used

sin - Sine is a trigonometric function that describes the ratio of the length of the opposite side of a right triangle to the length of the hypotenuse., sin(Angle)

Variables Used

Diameter of Big Pulley - (Measured in Meter) - Diameter of Big Pulley is the distance from side to side of the flat of the Big pulley.
Diameter of Small Pulley - (Measured in Meter) - Diameter of Small Pulley is the distance from side to side of the flat of the Small pulley.
Centre Distance between Pulleys - (Measured in Meter) - Centre Distance between Pulleys is the distance between the centers of the big pulley and the small pulley.
Wrap Angle on Big Pulley - (Measured in Radian) - Wrap Angle on Big Pulley is the angle that the Belt wraps around the Big Pulley.

STEP 1: Convert Input(s) to Base Unit

Diameter of Small Pulley: 270 Millimeter --> 0.27 Meter (Check conversion here)
Centre Distance between Pulleys: 1575 Millimeter --> 1.575 Meter (Check conversion here)
Wrap Angle on Big Pulley: 200 Degree --> 3.490658503988 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = d+2*C*sin((α_b-3.14)/2) --> 0.27+2*1.575*sin((3.490658503988-3.14)/2)

Evaluating ... ...

D = 0.819461906679916

STEP 3: Convert Result to Output's Unit

0.819461906679916 Meter -->819.461906679916 Millimeter (Check conversion here)

FINAL ANSWER

819.461906679916 ≈ 819.4619 Millimeter <-- Diameter of Big Pulley

Define Wrap Angle?

The wrap angle is defined as the angle between the run-up and run-off of the belt on the pulley. In addition, the greater curvature causes greater bending stresses in the belt, which also limits the transmittable belt force. So-called idler pulleys can be used to increase the wrap angle.
