All you need to know about shaft alignment

In machinery maintenance, shaft alignment is one of the most crucial processes. It impacts not only the efficiency but also the longevity of the equipment, which directly translates into cost optimization and profitability for the whole company.

Let’s examine this procedure and learn about its goals, strategies, and best practices.

Why is shaft alignment crucial to the upkeep of machinery?
Shaft alignment basically guarantees that the rotational centers of linked shafts are exactly the same. Shaft misalignment in an angular or parallel form without this procedure might lead to:

increased noise and vibration, which can lead to an uncomfortable working environment, possible damage to nearby components, bearing and seal wear and tear that requires frequent replacements, energy loss from inefficient power transmission that raises operating costs, early equipment failure, and shorter machinery lifespan.
Consequently, in the event that proper alignment techniques are not employed, businesses run the danger of incurring increased expenses, a reduced equipment lifespan, decreased productivity, decreased worker safety, and decreased profitability.

What are the most common methods of shaft alignment?
In fact, there are multiple methods that can be used to achieve precise alignment of shafts, ranging from traditional techniques to advanced laser systems.

Among the traditional ones, there is, for example, the dial indicator method. It involves mounting indicators on the shaft and rotating them to measure displacement. Although it offers a certain level of accuracy, advanced-level systems offer more precision.

The laser approaches provide real-time data for adjustments by measuring the shafts’ precise positions using laser beams. Because of their ability to precisely and automatically detect misalignments of any kind, they are the most effective solution for crucial machinery.

Which methods work best for aligning shafts?
Half the battle has already been won by integrating this procedure into machinery maintenance, but for best outcomes, the alignment process must adhere to specific guidelines, such these:

ensuring the foundation and baseplates are secure through pre-alignment inspections; taking thermal growth into account, particularly in hot locations; and doing routine maintenance and monitoring to identify any misalignment early.

proper training to ensure that maintenance personnel are trained in alignment techniques and have access to the appropriate tools, especially when using advanced laser systems,
preparing detailed records of alignment activities and adjustments to track the machinery’s condition over time.

All in all, shaft alignment is a fundamental aspect of machinery maintenance that significantly impacts performance, efficiency, and longevity. By implementing accurate alignment methods and adhering to best practices, companies can prevent operational issues, reduce maintenance costs, and extend equipment life. Learn more
