What is the function of a motorcycle tensioner?

[MacLeilani]

The function of a tensioner is to guide and maintain tension, ensuring it always remains in the optimal tension state. Below is an introduction to tensioners: 1. Working Principle: A tensioner is a commonly used retaining device in belt and chain transmission systems. Its characteristic is to maintain appropriate tension in belts or chains during transmission, thereby preventing belt slippage or avoiding timing belt teeth from skipping or disengaging. It also prevents chain loosening or detachment and reduces wear on sprockets and chains. 2. Features: In terms of effectiveness, tensioners with spring structures are simple in design and inexpensive, making them widely used. Tensioners with rubber components, due to rubber's excellent elastic properties, have a longer lifespan than spring tensioners. However, they require higher-performance rubber, making them more expensive and less commonly used, typically found in high-end mechanical equipment.
