slip friction clutch
Noun: A slip friction clutch is a type of mechanical coupling device designed to transmit rotational force (torque) from one shaft to another. Its defining characteristic is that it is engineered to intentionally slip or disengage when the transmitted torque exceeds a predetermined safe level. This slipping action protects the machinery's components from damage due to overload or jamming.
The term is used specifically in mechanical and automotive engineering contexts to describe a safety feature within a power transmission system.
Examples: * The slip friction clutch in the conveyor system prevents motor burnout if a blockage occurs. * Engineers installed a slip friction clutch to safeguard the delicate gears from sudden shock loads. * When the drill bit jammed, the slip friction clutch slipped, preventing the drive shaft from twisting.
- Torque Limiting: A primary function of a slip friction clutch is torque limiting. It is calibrated to slip at a specific torque value, making it a passive safety device.
- Protection Mechanism: It acts as a mechanical fuse, sacrificing its own frictional engagement to protect more expensive or critical components like motors, gearboxes, or driven tools from damage.
- Safety Clutch: A general term for clutches designed to protect machinery, which includes slip friction clutches.
- Torque Limiter: A broader category of devices that limit transmitted torque, of which a slip friction clutch is one common type.
- Overload Clutch: Another synonym emphasizing its role in preventing damage from excessive load.
- Friction Clutch: The general category. A slip friction clutch is a specific type of friction clutch with a built-in safety slip feature.
- Safety clutch
- Torque limiter (mechanical type)
- Overload clutch
- Locking Clutch or Positive Engagement Clutch: A clutch designed to firmly lock two shafts together without slipping under load.
- Rigid Coupling: A direct, non-slipping connection between two shafts.
-
a friction clutch that will slip when the torque is too great
