Belt drive mainly include: flat belts, v-belts, synchronous toothed belt three, three belts have national standards, but the pulley due to the change of the transmission ratio, power is larger, not corresponding national standards or national standards cannot cover all the content, but the national standard to determine the selection scope, conditions of use, design method, etc.
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 is 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).
In addition to the standard number is similar to national standard of ISO 1081-1995 standard rules on the conveyor belt, v-belt and triangular edge belt, and the selection of grooved pulley, the design specification. It is divided into SPZ, SPA, SPB, SPC, and SPD type 5 pulley.
It seems to be the output speed: the input speed = the diameter of the pulley diameter of the motor pulley
