The Challenge:
Product Showcase..Schenck Launches New Spare Parts Kit....3
It was approximately five years ago when
the Joe Gibbs Racing Team received driver
complaints
about
driveline
vibration
and approached Schenck about balancing
their redesigned driveshafts.
The Solution:
JGR and Schenck partnered to develop
and fine-tune a balancing process to balance
their newly designed driveshafts for their
NASCAR racing teams.
Working closely with the engineering staff
at Joe Gibbs Racing to meet their requirements, Schenck established a procedure, and
through a series of testing and analysis, finetuned and executed the procedure, to
balance and correct the JGR’s driveshafts to
a better balancing tolerance than what was
currently being used.

The
Schenck
HK40
/
CAB
920
driveshaft balancing system installed at
Schenck in Deer Park, NY provides excellent
repeatability and accuracy, and has been
applied successfully to balance hundreds of
JGR driveshafts over the past 5 years.
Balancing Theory: What is unbalance?
According to ISO 1925, Unbalance is that
condition which exists in a rotor when a
vibratory force, or motion, is imparted to its
bearings as a result of centrifugal force.
Rotation and unbalance in a driveshaft causes
centrifugal force to act on the driveshaft. The
centrifugal force increases with the square of
the speed.

The 2015 Sprint Cup season resulted in all four
cars making the Chase for the Cup.
The ultimate goal was achieved by Joe Gibbs
Racing in 2015 as their Number 18 race team,
with driver Kyle Busch, won the Sprint Cup
Championship!
All of us at Schenck congratulate our customer
and partner on the championship win and
another very successful season!
Schenck’s Unique In-House Balancing
Service Capabilities Include:
The remaining unbalance in the driveshafts,
when they are rotated, creates a centrifugal
force that is imparted to the rest of the
vehicle’s driveline as vibration. Reducing the
driveshaft unbalance is one way to reduce
overall vibration and improving performance.
Result:
The improved JGR shaft design and assembly
process, as well as control and precision provided by the balancing process, have resulted
in superior vibration measurements made on
dynamometers at the Joe Gibbs Racing facility
in Huntsville, NC as well as on the track. This
has resulted in no reported complaints of
driveline vibration by their team of now 4
drivers.
•
Low and high speed driveshaft balancing
(automotive & aerospace)
•
R&D / Prototype development balancing
•
Contract and large volume balancing
•
Turbine and Compressor and Blade moment
mass weighing, and blade set distribution
•
Balancing of Rotors from a few ounces up to
10,000 pounds
•
Balancing of Rotors with and without
journals, and self-driven assemblies
It has been more than five years of balancing
these driveshafts with improved results noted
by the JGR team when tested at approximately
9600 rpm. On race day, all four JGR teams
(No.18, No.11, No. 19 & no. 20 cars) in
the Sprint Cup Series had improved
results. The minimized driveline vibration
directly resulted in increased horsepower
and performance!!
Joe Gibbs Racing looked to Schenck to provide
balancing expertise, high quality, and
reliable service needed to help keep them at
the front of the field.

Introducing the CABflex3
After evacuating the test chamber, the rotor is
accelerated to its service speed or predefined
balancing speed and the measuring run is
conducted.
After measuring, the rotor is
decelerated to a stop, and air is reintroduced into
the test facility. Since each balancing run includes
these additional, time-consuming processes, it is
easy to understand that an operator will seek to
balance the rotor with the least amount of
measuring and correction runs as possible.
CABflex3 features expanded capabilities such as online evaluation, for real-time measuring and analysis
processes
conducted
in
parallel.
Remote
diagnostics for Schenck Service, remote monitor
display for customer viewing areas, and an offline software version for office use, provide
reliability and flexibility for the new
CABflex3
System.
Integration
of
force monitoring and
process data is also built-in.
Schenck is excited to announce our latest
flexible rotor balancing solution!
The vast majority of high-speed balancing and
over-speed testing facilities employ Schenck’s
CABFLEX Flexible Rotor Balancing System for
balancing and testing of compressor, turbine,
and generator rotors. The CABFLEX Systems
are used to analyze rotor vibrations to calculate
unbalance corrections.
The latest CABFLEX System, CABflex3, follows
in the footsteps of its successful predecessors,
and provides additional capability and increased
efficiency. The new CABflex3
provides
significant
advances
in measuring and
process functions. An improved measuring
chain and expanded analysis tools, integrated
into a modern, simple user interface, makes it
all possible.
High-speed balancing of turbine and generator
rotor requires extensive knowledge, since these
rotors are flexible and therefore exhibit different
dynamic behavior and vibration amplitudes with
a change in speeds. Balancing is often time
consuming and therefore expensive in terms of
operating
costs,
especially
considering
balancing of the largest turbine rotors requires
accelerating rotors in excess of 300 tons to
their service speeds.
Our template-based printing with built-in Microsoft
Word® templates automatically populates certain
fields with measurement data and graphs. This
standardizes your printout formatting with data such
as rotor information, test data, procedure, and
notes, and allows for customized layouts to
incorporate your company branding and logos with
your customer data.
CABflex3 offers a new operating concept that
increases efficiency of the balancing process.
Clearly-arranged, interactive graphics, combined
with a logical navigation structure, ensure quick
and error-free operation of the software.
The CABflex3 System further improves the
efficiency of the flexible rotor balancing, and will
continue to be the standard at test facilities
worldwide. It is available as a new system and
modernizations of existing systems. Regardless of
the existing hardware setup, the new CABflex3
System can be configured with hardware and
software options to meet the specific needs of each
end-user.
For balancing of these bladed rotors, the
facilities are equipped to operate under vacuum
conditions to reduce frictional losses and heat
generated by windage. With an evacuation time
of up to 45 minutes in the largest facilities, this
is a time consuming step required prior to each
measuring run.

Off-Line Condition Monitoring:
Power Generation and Beyond
In our last issue, we focused on online
condition monitoring. This issue focuses on
Schenck's
off-line
condition
monitoring
services.
Schenck has been providing condition
monitoring equipment and services for over 20
years! Here is a clear example of how our
service can result in cost savings.
We have been
contracted by a Power
Generation Plant to perform off-line condition
monitoring service for their plant since 2013.
This service includes routine-based data
collection and analysis of auxiliary plant
equipment. The plant has a total of 50
machines made up of various
pumps,
compressors and fans.
The routine data collection includes taking overall
vibration readings and FFT spectrums to see the
overall machine condition plus the BCU (Bearing
Condition Unit) and envelope spectrum to analyze
the bearing condition. After the data is collected
our software program is used to analyze
the vibration readings and look at the overall
trend.
Figure 1 shows the trend diagram from July 2013
to January 2016 for a motor’s outboard bearing
in the horizontal direction. The overall vibration
reading taken in January 2016 is high (greater
than 0.3 in/sec). Figure 1 also shows the
frequency spectrum with a high peak at the
running speed which is an indication for
unbalance.
Figure 1
Based on this unbalance indication, the plant's
maintenance department was notified of our
findings and an appropriate balancing procedure
was performed on this motor! Statistics show that
a reduction of the vibration level by 20% will
increase the bearing life by 95%.
