Center Distance from Small Pulley to Big Pulley given Wrap Angle of Small Pulley Solution

STEP 0: Pre-Calculation Summary

Formula Used

Centre Distance between Pulleys = (Diameter of Big Pulley-Diameter of Small Pulley)/(2*sin((3.14-Wrap Angle on Small Pulley)/2))
C = (D-d)/(2*sin((3.14-α_s)/2))
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

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.
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.
Wrap Angle on Small Pulley - (Measured in Radian) - Wrap Angle on Small Pulley is the angle that the Belt wraps around the Small Pulley.

STEP 1: Convert Input(s) to Base Unit

Diameter of Big Pulley: 810 Millimeter --> 0.81 Meter (Check conversion here)
Diameter of Small Pulley: 270 Millimeter --> 0.27 Meter (Check conversion here)
Wrap Angle on Small Pulley: 160.67 Degree --> 2.80422050917876 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C = (D-d)/(2*sin((3.14-α_s)/2)) --> (0.81-0.27)/(2*sin((3.14-2.80422050917876)/2))

Evaluating ... ...

C = 1.61577823838388

STEP 3: Convert Result to Output's Unit

1.61577823838388 Meter -->1615.77823838388 Millimeter (Check conversion here)

FINAL ANSWER

1615.77823838388 ≈ 1615.778 Millimeter <-- Centre Distance between Pulleys

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.
