What is the effect of material selection on the transmission efficiency of raw-edge v belts

In modern transmission systems, Raw-Edge V Belts are key power transmission components, and their transmission efficiency is affected by many factors. The physical, chemical and mechanical properties of materials are important indicators that determine their performance. Reasonable material selection can significantly improve the overall efficiency of the transmission system.

The physical properties of materials are one of the core factors that affect the transmission efficiency of Raw-Edge V Belts. Specifically, indicators such as elastic modulus, elongation and hardness are directly related to the performance of the belt under working conditions. When materials with high elastic modulus are subjected to the same stress, their deformation degree is relatively small, which can effectively reduce the elastic sliding phenomenon during the transmission process, thereby improving the transmission efficiency. At the same time, materials with low elongation can maintain a stable length during long-term operation, avoiding the decrease in preload and slippage caused by material elongation. In addition, the hardness of the material is also closely related to the friction coefficient. Moderate hardness can ensure good contact between the transmission belt and the pulley, enhance friction, reduce the risk of slippage, and thus improve transmission efficiency.

Heat resistance, oil resistance and corrosion resistance are key indicators. In high temperature environments, materials with good heat resistance can maintain the stability of their physical and chemical properties and avoid the reduction of transmission efficiency due to softening. Materials with good oil resistance perform well in lubricating oil or hydraulic oil environments, ensuring long-term use without being affected. In addition, materials with good corrosion resistance can effectively resist the erosion of corrosive media such as acids and alkalis, extend the service life of the transmission belt, and improve the overall transmission efficiency.

Mechanical properties are another key factor affecting the transmission efficiency of Raw-Edge V Belts, including tensile strength, fatigue resistance and wear resistance. High tensile strength of the material means that it can withstand greater tension, reducing the risk of breakage during transmission, thereby improving transmission efficiency. Materials with good fatigue resistance can maintain stable performance under frequent start-stop and speed-changing transmission, avoiding the reduction of efficiency due to fatigue. Materials with strong wear resistance can reduce the wear between the transmission belt and the pulley, extend the service life, reduce maintenance costs, and further improve transmission efficiency.

In practical applications, the material selection of Raw-Edge V Belts must take into account specific working conditions and environmental factors. For example, for transmission systems operating in harsh environments such as high temperature, dust, and humidity, materials with excellent heat resistance, oil resistance, corrosion resistance, and wear resistance should be preferred. At the same time, for transmission systems that bear high loads and high speeds, high-strength, low-elongation, and high-elasticity materials are required to ensure that excellent transmission efficiency can be maintained under harsh conditions.
