variable drive belt

The most common material used in timing belts is various types of rubber. Synthetic rubber, such as neoprene, is often preferred due to its superior resistance to heat and wear compared to natural rubber. The rubber provides flexibility, allowing the belt to bend around pulleys without cracking. This elasticity also contributes to a quiet operation, reducing engine noise. However, rubber's susceptibility to degradation from oil, heat, and ozone exposure necessitates the incorporation of additives and reinforcements.

To ensure optimal performance and prolong the lifespan of wrapped V-belts, regular maintenance is crucial. This includes inspecting belts for signs of wear, such as cracks or fraying, and checking tension and alignment regularly. Proper tensioning is especially important, as both under-tensioned and over-tensioned belts can lead to excessive wear or failure. Additionally, keeping the pulleys clean and free from debris will help maintain the belt's integrity and efficiency.
