The pulley groove is a shallow one, two different sides, and the belt is new
The type of the triangle is: the common type O A, B, C, D, E, 3V, 8V, the ordinary plus strong type AX BX CX DX EX 3VX 5VX 8VX, narrow V SPZ SPA SPB SPC, and the narrow V band XPA XPB XPC. Each model of the triangle has the section size of the triangle belt, the section size of A type A triangle is: the top width is 13mm, the thickness is 8mm. The section size of type B triangle is: the top width
pulley Degree 17MM, the thickness is 10.5 MM. The section size of C type triangle is: the top width is 22MM, the thickness is 13.5 MM. The section size of the D type triangle is: the top width is 21.5 MM, the thickness is 19MM. The section size of E type triangle is: the top width 38MM, the thickness is 25.5 MM. Dimensions (width * height) : O (10 * 6), A (12.5 * 9), B (16.5 * 11), C (22 * 14), D (21.5 * 19), E (38 * 25.5).
Standard regulations of the state of v-belt type O, A, B, C, D, E, F seven kinds of models, there are three kinds of corresponding pulley wheel groove Angle 34 °, 36 °, 38 °, at the same time, rules for each triangle model corresponding to each small minimum diameter of pulley groove Angle, large pulley provisions have been made. The grooves of the pulley are divided into 32 degrees 34 degrees 36 degrees 38 degrees, depending on the grooves and the base diameter of the belt wheel. The pulley groove Angle related to the diameter of the pulley, different models of belt pulley groove Angle under different diameter range of pulley groove Angle number is as follows: O pulley on the pulley in 50 mm to 71 mm diameter range is 34 degrees; At 71mm ~ 90mm, it is 36 degrees, > 90mm is 38 degrees. A type A pulley is 36 degrees for the wheel diameter of 71mm to 100mm, and for 100mm ~ 125mm. > 125 mm is 38 degrees; The type B pulley is 34 degrees in diameter from 125mm to 160mm. 160mm ~ 200mm is 36 degrees, > 200mm is 38 degrees; The c-type pulley is 34 degrees in diameter between 200mm ~ 250mm, 36degree for 250mm ~ 315mm, and 38 degrees for > 315mm. The d-type pulley is 36 degrees in diameter from 355mm to 450mm, and 38 degrees for > 450mm. The E type 500mm ~ 630mm is 36 degrees, > 630mm is 38 degrees.
