V-belt is also called triangular belts, also called cloth-covered V-belt. The triangle has two kinds of special core structure and rope core structure. The rope core is also an ordinary belt core, which is twisted or woven from fibers. The special belt core is composed of polyester tempered brown wire, with good adhesion, flex resistance, high strength, no stretching, and its service life is 5-10 times that of the V-belt with rope core structure.
V-belt can be divided into normal V-belt and narrow V-belt according to specifications
Ordinary V-shaped triangle belt is divided into seven levels: Y, Z, A, B, C, D, E
Narrow V-belts are divided into ordinary narrow V-belts and powerful narrow V-belts.
The ordinary narrow V has four specifications: SPZ, SPA, SPB, and SPC.
Powerful narrow V with XPA, XPB, XPC
Combined V-belt, several identical ordinary V-belts or narrow V-belts work together. There are 3V, 5V, 8V and so on.
The cross-sectional area of O-type, A-type, B-type, C-type, D-type, and E-type tapes gradually increases.
The top width and thickness, the top width and thickness can be determined to determine the pulley groove of the V-belt, and vice versa, the pulley groove of the pulley determines the type of V-belt (A/B/C..) that should be used.
Ld: reference length. When the V-belt rotates and bends around the pulley, the layer whose length and width remain unchanged is called the neutral layer. Under the specified tension, the circumference measured along the neutral layer of the triangle belt is called the reference length Ld
La: outer circumference
Li: inner circumference
Lw: the length of the pitch line is the length of the center line of the triangle belt
The model identification of ordinary V-belts is generally: A 950 LI 1150 Ld
The model identification of the narrow V-belt is generally: SPC 1500 LW
The parameters of the hexagonal belts are roughly the same as the above description. Welcome to consult and contact us.
