Under what conditions are silent chains used?

Silent chains are specifically designed for high-speed applications due to their unique construction, which minimizes noise and vibration. These chains consist of a series of interconnected links that mesh smoothly, allowing for efficient power transmission at elevated speeds. The design helps to reduce wear and extend the lifespan of the chain when used in situations where conventional chains might be less efficient.

In contrast, silent chains are not typically preferred in low-speed applications, as their design benefits, such as reduced noise, are less critical at lower operational speeds. Additionally, while silent chains can perform adequately under corrosive conditions, there are generally better-suited materials and chain types for corrosive environments. Although they can handle moderate stress loads, they are particularly optimized for high-speed scenarios rather than high stress. Thus, their primary application focus is in environments where high-speed movement is paramount.
