What are the commonly used materials for timing pulleys?

The timing belt is made of steel wire rope or glass fiber as a strong layer, and an endless belt covered with polyurethane or neoprene. The inner circumference of the belt is made into a tooth shape to make it mesh with a toothed pulley. When the synchronous belt is driven, the transmission ratio is accurate, the force on the shaft is small, the structure is compact, the oil resistance, the wear resistance is good, the aging resistance is good, the general use temperature is -20 ℃-80 ℃, v<50m/s, P<300kw, i<10, can also be used for low-speed transmission for the transmission that requires synchronization. Frequently, customers inquire about the materials commonly used for timing belts and pulleys? The materials used by our company are as follows: 1. Rubber timing belt material/material: high-quality synthetic neoprene + skeleton material is imported high-quality glass fiber cord + toothed surface adopts nylon 66 high-elasticity cloth + various auxiliary materials for different purposes; 2. Polyurethane timing belt material/material: Polyurethane belt back + steel wire rope (or polyester rope) tensile layer + polyurethane belt teeth 3. Synchronous pulley material/material: according to your machine, heavy or light, the commonly used pulley materials are: aluminum alloy, steel, cast iron, stainless steel, nylon, copper, plastic, POM polyoxymethylene plastic (Saigang )Wait. Among them, 45# and aluminum alloy are the most common.
