The raw edge V belt refers to a type of V-belt that has no fabric wrapping on its two working sides. Its compression rubber is reinforced with directional short fibers, while the tensile cord consists of specially hardened, high-strength synthetic fibers—commonly polyester. Thanks to its unique structure and material composition, the raw edge V belt offers enhanced transmission efficiency—typically about 10% higher than that of a wrapped V-belt—due to increased contact area and friction with the pulley.
Unwrapped Working Surfaces
Unlike wrapped V-belts, the raw edge V belt eliminates fabric covering on the sides, allowing the belt to make direct contact with the pulley. This design reduces energy loss from friction and enhances overall transmission efficiency.
Advanced Materials and Construction
The compression layer is embedded with directional short fibers, improving resistance to compression and maintaining structural stability. The tensile cord is made from specially treated, high-strength synthetic fibers that provide excellent tensile strength and enable the belt to perform reliably under high-speed and heavy-load conditions.
Higher Power Transmission Capacity
Due to its superior efficiency, the raw edge V belt can transmit greater power under the same conditions compared to traditional belts. This makes it ideal for applications where high power transmission is required.
Extended Service Life
Reinforced with directional short fibers in the rubber and hardened synthetic tensile cords such as polyester, the raw edge V belt offers high strength and fatigue resistance. These qualities significantly increase its durability and operational lifespan.
Energy Efficiency
The higher transmission efficiency means less energy is lost during operation. As a result, the raw edge V belt contributes to reduced power consumption and more energy-efficient system performance.
Compact Transmission Design
Thanks to its structural design, the raw edge V belt requires less installation space, allowing for more compact and efficient mechanical layouts. This is particularly advantageous in applications where space constraints are a concern.
High-Speed Capability
Its advanced material composition and construction allow the raw edge V belt to maintain stable performance even at high speeds. It is well-suited for equipment that demands fast and reliable power transmission.
Excellent Flexibility
Toothed raw edge V belt offers outstanding flexibility, enabling use with smaller pulley diameters and broader speed ranges. It is ideal for producing variable speed V-belts used in industrial continuously variable transmissions (CVTs) and motorized scooters.
