töörihmad

Töörihmad, also known as conveyor belts or transmission belts, are continuous loops of material used to transfer power from one rotating shaft to another or to move materials from one place to another. In industrial settings, they are crucial for powering machinery and transporting goods on assembly lines. For personal use, such as in cars, they are essential for operating various components.

The design and material of a töörihm depend heavily on its intended application. For power transmission, belts are often made from rubber, neoprene, or polyurethane, reinforced with cords of steel, polyester, or Kevlar for added strength and to prevent stretching. These belts typically have a V-shape or a flat profile to ensure proper grip on the pulleys. In contrast, conveyor belts, designed for material handling, are generally wider and flatter, made from durable rubber or fabric composites that can withstand abrasion and heavy loads.

The functioning of a töörihm relies on friction between the belt and the pulleys. When one pulley is rotated, it drives the belt, which in turn rotates the second pulley. This simple mechanical principle allows for efficient power transfer over distances. Maintenance is key to ensuring longevity and preventing breakdowns. Regular inspection for wear, tension adjustment, and proper alignment are necessary to optimize performance and safety. Different types of töörihmad exist, including synchronous belts (timing belts) which have teeth to ensure precise synchronization between shafts, and V-belts, commonly used in automotive applications.
