What does the term “misalignment” refer to in power transmission systems?

The term “misalignment” in power transmission systems specifically refers to the improper alignment of rotating shafts. When two or more shafts are connected by couplings, they must be aligned correctly to ensure efficient transfer of power and minimize wear and tear on the components. Misalignment can lead to increased vibration, premature failure of bearings, and excessive wear on the connecting parts, which can ultimately cause operational issues and increased maintenance costs.

In contrasting instances, alignment of electrical circuits, fixed structures, and the positioning of belts in relation to pulleys do not directly pertain to the alignment of rotating shafts. While these factors may play a role in overall system performance, they are not classified under the term "misalignment" in the context of power transmission. Misalignment specifically highlights the critical importance of aligning rotating elements to maintain system integrity and functionality.
