Shaft Alignment Tool
Designed for professional alignment in harsh industrial environments,
the TKSA 71 complements SKF's offering with a high-end shaft alignment
tool. The instrument is very versatile with ultra-compact measuring
units for use in extremely narrow spaces. Its dedicated software
applications enable different types of alignments, including horizontal
and vertical shafts, spacer shafts and machine trains. Superior
alignment performance and long-term industrial durability are achieved
with an innovative instrument design that offers high measurement
accuracy and excellent protection against dust and water in harsh
environments.
Shaft Alignment Overview
Shaft misalignment is one of the most significant and most preventable
contributors to premature machine failure. When a machine is placed in
service with less than optimal shaft alignment, the following conditions
are likely:
- Poor machine performance
- Increased power consumption
- Increased noise and vibration
- Premature bearing wear
- Accelerated deterioration of gaskets, packing, and mechanical seals
- Higher coupling wear rates
- Increased unplanned downtime
Proper alignment is achieved when the center lines of each shaft are
co-linear when the machine is under load and at normal operating
temperatures. This is often referred to as shaft-to-shaft alignment. If
the shafts of a machine train are not co-linear, when the machine is in
operation, they are misaligned. In essence, the objective is to have a
straight line through the centers of all of the shafts of the machines.
The SKF Shaft Alignment for TKSA 71 is a wireless shaft alignment tool
that allows an easy and accurate method for aligning the shafts of a
driving machine (e.g. electric motor) and a driven machine (e.g. pump).
Principle of Operation
The TKSA 71 is a Line Laser Shaft Alignment System and it has two
measuring units that are mounted on each shaft, or on each side of the
coupling. After rotating the shafts into different measuring positions,
the system calculates offset and angular misalignment values between the
shafts. The values are compared with user defined tolerance limits and
adjustments of the machine can be made instantly.
During the measuring procedure, measurements are taken in three
positions, each separated by at least 20°. As the shafts are rotated
through an arc, any parallel misalignment or angular misalignment causes
the detectors to measure the difference in their positions relative to
each other.
Positioning information from the measuring units is wirelessly
communicated through Bluetooth Low Energy to the displaying device,
which calculates the amount of shaft misalignment and advises corrective
adjustments of the machine feet.
If the shafts of a machine train are not co-linear when the machine is
in operation, they are by definition misaligned. While the actual shaft
positions can be illustrated in three dimensional space and the center
lines can be defined mathematically, it is easier to relate the
relationship between shafts at the coupling as an offset, an angle, or
any combination of the two in the vertical and horizontal axes.
Alignment Applications
The TKSA 71 functions quickly and intuitively using six software apps
tailored for different alignment jobs. Designed for use without prior
training, these simple-to-use apps are available free of charge for both
Android and iOS platforms. Common features include comprehensive,
automatic reports, export and sharing options, instructional videos
within the app, built-in tolerance guidelines, 3-D live view,
disturbance compensation and a fully functional demonstration mode.

The SKF Shaft Alignment Tool TKSA 71 has achieved high user satisfaction
in wind turbines where its compact, lightweight design has helped
technicians to carry the instrument up the tower and perform alignments
in very narrow spaces. In general industrial applications, technicians
benefit from the tool’s versatility and ease of use, instantly becoming
familiar operating the tool and performing machine alignment. Developed
especially for demanding alignment tasks, the TKSA 71 provides superior
performance in vertical shaft and machine train alignments.
