Definition
  1. Noun:
    • Mechanical connector: A "screw coupling" is a device used to connect two shafts or pipes by means of a threaded (screw) mechanism, allowing them to rotate together or to be securely joined in a mechanical system.
    • Railway component: In rail transport, a "screw coupling" is a type of coupling used to link railway carriages or wagons together, consisting of a screw thread that tightens the connection.
Usage Examples
  • (A threaded connector for rotating machinery.)
  • (A coupling device on trains.)
Advanced Usage
  • "screw coupling in engineering": a threaded joint used in pipelines or rotating equipment.

    • The pump's screw coupling allowed for easy disassembly during maintenance. (A threaded connector for easy removal.)
  • "screw coupling in railways": also known as a "screw coupler," it is a standard coupling in many European rail systems.

    • The old steam locomotive still used a screw coupling instead of automatic couplers. (A manual, threaded coupling.)
Variants and Related Words

    • The screw coupling relies on the screw's threads to hold the connection firm. (The coupling uses a screw component.)
  • Coupling (n): a device that connects two things together.

    • A screw coupling is a specific type of coupling that uses a threaded mechanism. (A general connector with a screw design.)
Synonyms
