In which power transmission system is a torque transmitted of high capacity, typically with a speed ratio of 3:1?

The transmission of torque in a high-capacity system with a speed ratio of 3:1 is most commonly associated with a chain drive. This type of system is designed to efficiently transfer power between shafts while allowing for high torque transmission. Chain drives utilize a set of gears that engage with links of a chain, allowing for a robust and reliable connection that is ideal for applications requiring significant power, such as in heavy machinery or automotive applications.

Chain drives excel in situations where there is a need for greater distances between drive components, and they are less prone to slippage compared to belt drives. The 3:1 speed ratio indicates that for every three rotations of the input, the output will make one complete rotation, which is beneficial in providing a mechanical advantage to the system, enabling it to handle high loads effectively.

In contrast, while belt drives and gear drives can also transmit torque, they do so under different conditions and limitations. Belt drives are more suited for lower torque applications and may not achieve high torque transmission with the same reliability as chain drives. Gear drives can handle high torque but typically do not achieve speed ratios as efficiently as chain systems for specific designs. Hydraulic drives, on the other hand, operate on different principles, using pressurized fluid instead of
