OEMs (Original Equipment Manufacturers) are no longer using V-Belts in their machinery or engines due to several reasons, including the evolution of power transmission technology and the specific advantages and disadvantages of V-Belts compared to other power transmission methods.
One reason for the shift away from V-Belts is the increasing use of serpentine belts. Serpentine belts are more efficient than V-Belts, as they have a larger surface area in contact with the pulley and can transmit power more effectively. Additionally, serpentine belts have a longer service life than V-Belts and require less maintenance. OEMs have also been opting for direct drive systems, which eliminate the need for belts altogether and provide even greater power transmission efficiency.
Another reason for the decline in the use of V-Belts is their limited speed capability. V-Belts are designed for lower speed applications and are not suitable for high-speed machinery and engines. As technology advances and machines become more powerful, the need for higher speed power transmission methods has increased.
V-Belts also have a tendency to slip, reducing power transmission efficiency and requiring more frequent adjustments. This can lead to increased maintenance costs and downtime for machinery and engines. Serpentine belts and direct drive systems have a lower risk of slipping and require less maintenance, making them more attractive to OEMs.
The shift away from V-Belts has impacted the industry as a whole, with many manufacturers discontinuing V-Belt production lines and focusing on serpentine belts and direct drive systems. While V-Belts still have their place in some machinery and engines, their use is becoming less common in new equipment.
In summary, OEMs are no longer using V-Belts in their machinery and engines due to the increasing use of more efficient power transmission methods such as serpentine belts and direct drive systems. The limited speed capability and tendency to slip of V-Belts have made them less attractive to manufacturers, who are looking for more reliable and efficient power transmission options.
