The difference between SPB v-band and b v-band

There are three differences between SPB V belt and B V belt * * *:

1, with different cross-sectional areas: SPB V tape has a narrow cross-sectional area and belongs to narrow V type; The cross-sectional area of B-V belt is very large.

2. The rubber formula of SPB V belt is different: the rubber formula of SPB V belt is more complicated and diverse; The rubber formula of B-type V-belt tape is simple.

3. Their compositions are different: SPB V tape consists of wrapping layer, stretching layer (top glue), strength layer, compression layer and buffer glue; While the B-V belt has no cushion rubber layer.

Extended data triangle classification:

1, ordinary belt core

The cores of ordinary V-belts with cores are mostly cord cores, and a few are cord cores. Because these two kinds of belt core structures are twisted or braided by fibers, the mutual shearing between fibers leads to the gradual fracture and elongation of the belt core during the operation of V-belt. Therefore, the common V-belt produced by cord belt core and cord belt core can only be used in low-load transmission system.

2. Special belt core-polyester toughened brown belt core

The belt core of the special V-belt with core adopts the integral solid rod-shaped belt core structure of polymer polyester toughened brown silk. Because polyester tempered brown silk is a solid and untwisted structure with good adhesion, flexibility resistance, high strength and no running length, it not only greatly improves the service life of rubber transmission belt, but also has a balanced service life, so enterprises can realize maintenance-free and regular replacement.
