Học thuậtThân thiện
Definition
- Noun:
- A revolving rod that transmits power or motion: A cylindrical mechanical component that spins around its longitudinal axis to transfer energy, torque, or movement from one part of a machine to another.
Usage Examples
- Noun:
- The engine's rotating shaft connects directly to the gearbox.
- A broken rotating shaft caused the entire assembly to seize.
- Power from the turbine is delivered via a long, steel rotating shaft.
Advanced Usage
- Technical Context: In engineering, a "rotating shaft" is a fundamental element in systems like motors, pumps, compressors, and transmissions. Its design must account for factors like torsional stress, rotational speed, and bearing support.
- The design team analyzed the fatigue life of the rotating shaft under maximum load.
Variants and Related Words
- Shaft (noun): A broader term for a long, cylindrical rod or bar. Not all shafts rotate (e.g., a stationary axle).
- Drive Shaft (noun): A specific type of rotating shaft that transmits torque from the engine to the wheels in a vehicle.
- Rotor Shaft (noun): The rotating shaft within an electric motor or turbine.
- Axle (noun): A shaft on which a wheel rotates. An axle may or may not itself rotate, depending on the design.
Synonyms
- Spindle: A slender rotating shaft, often used in machinery for holding a tool or workpiece.
- Arbor: A shaft or spindle on which a cutting tool or workpiece is mounted.
- Mandrel: A shaft or bar used to hold a workpiece during machining.
Related Phrases
- Shaft Rotation: Refers to the act or speed of the shaft's spinning motion.
- Monitor the shaft rotation to ensure it does not exceed the rated RPM.
- Shaft Alignment: The process of ensuring two or more rotating shafts are correctly positioned relative to each other.
- Proper shaft alignment is critical for reducing vibration and wear.
