How does angular misalignment affect rotating machinery?

Angular misalignment occurs when two shafts are not aligned at the appropriate angle, which can significantly affect the performance and lifespan of rotating machinery. When angular misalignment is present, the components of the machine do not rotate in a perfectly symmetrical manner, leading to uneven distribution of forces.

This misalignment creates conditions that cause uneven wear on bearings and seals, ultimately shortening their lifespan. Additionally, the imbalance caused by angular misalignment can lead to increased vibration. Excessive vibration can not only diminish the performance of the machinery but also lead to secondary issues such as structural damage or increased maintenance needs.

In contrast, the other options suggest that misalignment either enhances efficiency, has no effect, or reduces power consumption, which is not accurate. Angular misalignment typically detracts from the efficiency and operational stability of rotating machinery, emphasizing the importance of proper alignment in the performance and reliability of mechanical systems.
