How do you calculate the center distance of the belt wheel? Thank you!
The size and center distance of the belt wheel are generally determined according to the requirements of the structure and the transmission ratio. Because the length of the triangle is divided according to the series, so can only choose and design the closest size triangle, finally according to the actual size of the selected triangle to determine the center distance of two pulley. Belt transmission mechanism design want to consider the problem of center distance adjustment, because the triangle belt transmission at work after a period of time often take the tension becomes smaller (loose) need to be adjusted.
The dl band has a round, a triangle with a nodal line, which is the basis for calculating the ratio of the transmission ratio and the center distance. You know the principle and you can calculate it. All I know is that I don't have the formula.
Start by measuring the maximum distance between the two wheels (take the outer diameter of the wheel), subtract the radius of the small wheel and subtract the radius of the big wheel, which is the center of the center
