What are the characteristics of rubber wide-angle belts compared with other types of V-belts?

1. Structural design advantages

The rubber wide-angle belt adopts a 60° angle design (normal V-belts are usually 40°), which increases the contact area between the belt body and the pulley groove wall by about 30%. This design can reduce the pressure per unit area, reduce the risk of slipping, and increase the transmission efficiency to more than 98% (normal V-belts are about 90-95%).

Multiple narrow belts are combined into a whole through the top rubber layer to prevent a single belt from falling off or flipping. Rope core structure V-belts (general tensile strength) are prone to chain failures due to single-root breakage, while the wide-angle belt joint design ensures system stability.

2. Material performance advantages

The rubber wide-angle belt adopts ethylene propylene diene monomer (EPDM), and its temperature resistance range is only slightly increased compared to ordinary V-belts.

The surface of the rubber wide-angle belt is woven with 120~135° warp and weft yarns, and is bonded to the belt body through vulcanization, which increases the wear resistance by 40%, and is resistant to oil, acid and alkali corrosion.

Anti-fatigue and anti-stretching——

Skeleton layer: Aramid cords are arranged longitudinally, with a tensile strength of ≥25MPa and an elongation of <1% (the elongation of ordinary polyester cord core is about 3-5%).

Belt body design: The transverse groove structure disperses stress, reduces bending fatigue, and has a service life of 2-3 years (about 6-12 months for ordinary V-belts).

3. Adaptation to special scenarios

The low vibration of the rubber wide-angle belt (40% reduction in centrifugal vibration) is suitable for CNC machine tools and medical equipment, and the transmission error is <±0.5mm. Adapt to the wheel diameter 5M type (such as Ø50mm) to save installation space.

Adaptability to complex environments——

Sanitary scenarios: EPDM material is certified, washable, and anti-microbial, suitable for food processing lines.

Corrosive environment: The wide-angle cloth layer blocks chemical medium erosion, and the service life is 50% longer than that of polyurethane belts (such as electroplating workshops).
