Selection of V-belts
Thread Content
Who knows the formula for calculating the length of V-belts, as well as the cross-sectional dimensions of type ABC?

It’s calculated by using the necessary numbers, such as the diameter of the two wheels and the distance between the centers of the two wheels, etc. I had notes on this a long time ago, but they’re not with me now.
The formula is L=2ao+pi(d1+d2)/2+(d1-d2)×(d1-d2)4ao, where ao is the center distance. d is the diameter of the two wheels; pi=π. The cross-sectional dimensions are A=13*8, B=17*10.5, C=22*13.5. The central angle Ψ is 40 degrees·
