Overview of Different Shaft Alignment Methods

Pros of regular shaft alignment checks include extended machinery life and the reduced likelihood of flexible couplings wearing out.

Types of shaft misalignment

There are two types of misalignment—angular misalignment and offset misalignment or parallel misalignment and they may occur in horizontal plane (axial) and vertical ( Radial) plane.

The distance between the shaft centers of rotation, typically measured at the coupling center, is called offset misalignment, or parallel

misalignment. It is usually expressed in mils (where 1 mil = 0.001 in.).

Angular misalignment is when the slope of one shaft (usually the moveable machine) is different than the slope of the shaft of the other machine (usually the stationary machine). This difference is sometimes referred to as “gap,” “face,” or simply “angularity.”

This measurement is similar to measuring the slope of a roof (i.e., rise/run). Mils are used to measure the rise, while inches are used to

measure the run (distance along the shaft). Mils per inch are used to measure angular misalignment.

Angular and parallel misalignment manifests itself in following interrelated problems Increased vibration

• Increased energy loss and high power consumption.
• Increased load on bearings, seals and other mechanical components
• Reduced production capacity
• Reduced product quality
• Reduced life span
• Coupling failures
• Increased repair time

Even the most conservative surveys carried out over the last ten year in a wide variety of industries indicate that 50% of all machine breakdowns are directly due to poor alignment. Some surveys have shown that as much of 90% of machines are running beyond their recommended tolerances.

Choose an Alignment Method

Shaft alignment system, alignment tools ( Brackets, Dials or laser shaft alignment tool)

End users must pick an appropriate precision alignment technique based on available alignment tools for their equipment after they’ve prepared for alignment.

Brackets and arms are required for installation of measuring equipment in several alignment approaches along with face dial indicators. As the arms get longer, they become more prone to sagging, which may cause significant measuring mistakes if end users don’t factor it into account; as a result, the arms become more prone to sagging.

Laser system with sensors are more accurate and less prone to sagging. It can be used to correct both horizontal misalignment and vertical misalignment.

RIM AND FACE DIAL METHOD

The oldest and most commonly utilized dial indicator technique is the Rim and Face technique. This is ideal for hubs with a short distance between shaft ends and large diameter. The method requires use of dial gauges horizontally and vertically to achieve correct shaft alignment.

Alignment measurements of driver and the driven piece of equipment may be offset as per manufacturer.

Advantages for RIM and Face Method:

• Rotating one shaft is all that is required.
• This method is simpler than others when trying to see the placement of the shaft.

Disadvantages of RIM and Face Method:

If there is any axial float, it is difficult to obtain face readings.

• Typically, the coupling must be removed by the user.
• Graphical calculations are more complicated than other methods.
• If the hub periphery is not round or flat and square relative to the shaft, the readings will be affected; if the hub face is out-of-square or out-of-round.

Method 2 — Reverse Dial Method

For most alignments, reverse Dial (indicator) is the most optimal method.

Advantages of Reverse Dial Method:

• In general, it is more accurate than the face and periphery methods.
• The readings are not affected by axial float, out-of-roundness, or out-of-squareness in the hub.
• Graphs can be plotted more easily than other methods.
• Measuring can be done with the coupling installed.

Disadvantages of the Reverse Dial Method:​

• Both shafts must be rotated by the end user.
• The method is not accurate for shafts that are closely coupled.
