2. What are round belts used for?
Round belts, also known as O-ring belts, endless round belts, or endless drive belts, are primarily used for power transmission applications. They are commonly used in line shaft or live roller conveyors and powered roller conveyors. These belts are designed to stretch and do not require a belt tensioner.
3. What are the different types of V-belts?
V-belts come in various types based on their cross-section dimensions. Some common types include standard, wedge, narrow, fractional horsepower, banded, cogged, and double V-belts. Each type is designed for specific applications and has different characteristics.
4. What material is used for O-ring belts?
O-ring belts are made from various rubber materials, including natural rubber, neoprene, EPDM, nitrile, and silicone rubber. The choice of material depends on factors such as heat resistance, oil resistance, chemical resistance, and abrasion resistance, based on the specific application requirements.
5. What are the two types of drive belts?
There are two main types of drive belts: V-belts and serpentine belts. V-belts are used in systems where the crankshaft pulley turns to drive other pulleys. Serpentine belts are used in systems where the belt travels around multiple pulleys in a serpentine path.
6. What is the alternative to rubber belts?
PVC belts are a popular alternative to rubber belts. They are lighter, use less energy in operation, and can reduce ongoing operational costs and carbon footprint. This makes them a growing priority in many industries.
