What are the features and advantages of ribbed belts

A ribbed belt, also known as a multi-ribbed belt, is a type of power transmission belt used in various applications. It is similar to a standard V-belt but has multiple ribs instead of a single groove. Ribbed belts are used to transmit power in machines and engines, such as cars, motorcycles, and industrial equipment. They are known for their high efficiency, low noise, and low maintenance requirements. 

A ribbed belt is made up of a flexible, reinforced rubber material with a series of ribs on the underside. The number of ribs can vary depending on the application, but the most common number is six. The ribs are designed to fit into grooves on the pulleys, creating a positive engagement that transfers torque. The ribs also increase the contact area between the belt and the pulley, allowing for greater power transmission.

Ribbed belts have several features that make them a popular choice for power transmission applications. Firstly, they have a high degree of flexibility, allowing them to bend and twist around pulleys without causing damage or slipping. Secondly, they have a high level of grip due to the ribbed design, which prevents slippage even under high loads. Thirdly, ribbed belts are known for their low noise operation, as the ribs reduce the vibration and noise associated with standard V-belts. Lastly, they have a long service life and require little maintenance, making them a cost-effective solution for many applications.

Ribbed belts have several advantages over other types of power transmission belts. Firstly, they are more efficient due to their ribbed design, which provides a greater surface area for power transmission. This results in less slippage and higher power transfer, reducing energy consumption and improving overall efficiency. Secondly, ribbed belts have a longer service life compared to standard V-belts due to their reduced wear and tear. This reduces downtime and maintenance costs, improving overall productivity. Lastly, ribbed belts are easy to install and adjust, requiring minimal tools and expertise.



This V-Ribbed Belts combines the high transmission of V-belt and  the flexibility of  flat belt. It contributes to system compactness, multi-axis layout, and small pulley diameter.
1. The transmission power is large, and the transmission power of the ordinary V-belt is 30% higher than that of the ordinary V-belt when the space is the same.
2. The drive system has a compact structure and can reduce costs. Under the same transmission power, the space of the transmission device is 25% smaller than that of the ordinary V-belt.
3. The belt body is thin and flexible, suitable for transmission with small diameter of pulley, and also suitable for high-speed transmission.
