A slip friction clutch is an essential mechanical component that connects and disconnects the power transmission between two shafts. In engineering, slip friction clutches are often referred to as slip clutches, overrunning clutches, freewheel clutches, or torque-limiting clutches. These synonyms describe the clutch's purpose of allowing smooth operation and protecting other mechanical parts from damage caused by excessive torque or sudden loads. Additionally, the slip friction clutch assists in improving overall vehicle performance and helps prevent sudden stops, stalls, or jerks. Each synonym has its specific use and application, but all of them serve the same purpose, which is to ensure safety and stability in power transmission systems.
