A slip clutch is used

• A. To Reduce Speed
• B. As A Brake
• C. As A Torque Arm
• D. To Limit Torque

Answer: (D)

Slip clutches are designed to protect a drive system by preventing excessive torque from being transmitted. They allow a bit of slippage when the torque demand exceeds a preset limit, so the drive can keep turning without overloading the motor or gears. Up to that limit, the clutch engages and transmits torque; once the limit is reached, friction surfaces slip, capping the torque that reaches the driven side. This makes it a torque-limiting device rather than a device to reduce speed or to brake. It’s not a torque arm, which is a structural lever, and it’s not used to actively slow or stop motion; instead it absorbs overload and allows harmless slip, then re-engages when load drops. The torque limit is usually adjustable by changing spring preload or friction coefficient, allowing customization for different equipment loads. In practice, it protects components like belts, gears, and motors, enabling smooth starts and preventing sudden jolts or stalling.
