1, what is the division of triangle specification? The specifications of the v belt is by the wide ( Back) With high ( Thick) The size of the dividing. 2, what's the size of the triangle model corresponding to? O ( 10 * 6) , type A ( 12. 5 * 9) , type B ( 16. 5 * 11) , C ( 22 * 14) And type D ( 21. 5 * 19) , E ( 38 * 25. 5) 3, how the Angle of the V belt options? V belt ( Base width) Angle is 40 degrees, and the belt pulley groove Angle is divided into 32 degrees, 34 degrees, 36 degrees, 38 degrees, according to specific choice of pulley groove diameter and benchmark choice. 4, pitch circle diameter of pulley, how to calculate? The diameter of the pulley minus twice the high pitch diameter can be obtained. The meaning of 5, model on the tag? Is A triangle model, O, A, B, C, D, E, F seven models, know model is equal to the triangle section size, type A is: the top 13 mm width, height 8 mm, 40 degree Angle; '800' for the triangle length within weeks, the unit is mm. 6, ceramic tile line two axis center distance is 3 m, C type pulley straight through to 250 mm. Would you please estimate the type of this group of triangle? Formula: L = 2 + Pi ao ( d1和d2) / 2 + ( d1 - d2) * ( d1 - d2) / 4 ao ao: center distance, d1, d2 is diameter.
