Description

Technical Field

[0001] The utility model relates to the technical field of training teaching aids, in particular to a training teaching aid for the concentricity of a horizontal pump coupling. Background Art

[0002] A coupling is a mechanical component used to connect two shafts (driving and driven) in different mechanisms, enabling them to rotate together and transmit torque. It typically consists of two halves, each connected by a key or tight fit, secured to the shaft ends and then joined together in some other manner. In high-speed, heavy-load power transmission, some couplings also provide cushioning, vibration reduction, and improved dynamic performance of the shaft system. Coupling concentricity error primarily refers to the eccentricity and tilt of the two shafts. Greater coupling concentricity error increases power loss, impacting torque transmission efficiency and correspondingly increasing motor current. In severe cases, this can lead to safety hazards such as motor burnout and mechanical collisions.

[0003] Coupling concentricity measurement is also known as wheel alignment. The motor shaft and pump shaft are connected by a coupling. After installation, the axes of the two shafts must be nearly aligned to ensure smooth, vibration-free operation. Currently, pump stations used in water conservancy projects are large and complex to inspect and maintain, making them difficult for interns to learn. Utility Model Content
