Main types of couplings
Published Time:
2025-06-25
Features: Simple structure, no buffering or compensation capability, requires strict alignment of the two shafts. Applicable scenarios: Suitable for occasions with high alignment accuracy, stable load, and no impact, such as low-speed, high-torque transmission systems.
Rigid Coupling
Features: Simple structure, no buffering or compensation capability, requires strict alignment of the two shafts.
Applicable scenarios: Suitable for occasions with high alignment accuracy, stable load, and no impact, such as low-speed, high-torque transmission systems.
Common types: Flange coupling, sleeve coupling, clamp coupling, etc.
Flexible Coupling
Features: Has the ability to compensate for the relative displacement of the two shafts; some types also have buffering and damping functions.
Applicable scenarios: Suitable for occasions with axial, radial, or angular displacement, such as high-speed, light-load, or impact transmission systems.
Common types:
Flexible couplings without elastic elements: Gear couplings, slider couplings, universal couplings, etc.
Flexible couplings with elastic elements: Elastic bushing pin couplings, star couplings, tire couplings, etc.
Safety Coupling
Features: When the transmitted torque exceeds the set value, the coupling will automatically disconnect or slip, protecting the equipment from damage.
Applicable scenarios: Suitable for occasions requiring overload protection, such as cranes and winches.
