PROGRAM The oldest pekrun gearboxes have now outlived us - they have been operating for more than 100
years. We are of course particularly proud of our history. Every pekrun gearbox, as well as every
gearbox manufactured by a third-party company, can be reconditioned by us, adapted to other requi-
rements or retrofitted with the latest monitoring technology. This means that we can secure your
investment and conserve your budget.
SERVICE However, the prerequisite for reliable and continuous operation is careful maintenance and quick
customer service provision - and our employees will be on site with you in 24h worldwide.
We are permanently striving to optimise every last detail - and it is these details that you learn to
appreciate over the lifetime of your pekrun gearbox. Material quality, manufacturing capabilities and
many years of design experience have now made our gearboxes into reliable high-tech tools. Now as
MÜHLENGETRIEBE
then, the final assembly and the test run are still an exhilarating moment. Therefore, you will continue
to find a certain passion in every pekrun employee as a proud gearbox manufacturer.
KNOW HOW We share this combination of know how and passion with selected partners and can now look back
on very successful synergies.
If you visit us you will feel the power of a 150t aggregate, the precision of a gear wheel or the aesthe-
tics of a turbo gearbox. This aesthetic is a common thread throughout all areas of the company at
pekrun. It is the living expression of our corporate identity and can be found of course in our buildings,
our internet presence and naturally our image brochures and this catalogue.

Areas of application pekrun has built turbo gearboxes since 1950 and followed the trend for greater performance, the highest rotatio-
nal speeds and longer product life cycles, while at the same time delivering the maximum level of operational safety.
Our fast-running spur gearboxes can be found worldwide across the energy generation sector. pekrun turbo gear-
boxes have been installed in the oil, gas, petroleum and chemical industries. They are driven by electrical motors,
combustion engines, gas turbines, steam turbines or water turbines. The processing machines include generators,
compressors, pumps or blowers that require high to very high rotational speeds.
Characteristics Extremely quiet operation, low vibration
Designed for continuous operation
High level of operational safety, long life cycle, low maintenance
pekrun advantages Environmentally friendly due to the high level of efficiency in the transfer of very high performance and rotational
speeds
Decades of know how and the latest calculation methods enable optimal adaptation to the customer‘s requirements
Certified quality management system
Quality testing including gearing measurement, ultrasound and non destructive test, noise, vibration, bearing clea-
rance and run-out measurements, 3D measuring arm, contact patterns and test runs
Comprehensive level of service with inspections and noise and vibration measurements
Quick repairs and provision of spare parts for our own and third-party products
All industry standards are available: DIN, API, AGMA

Models Spur gearbox
Sizes Center distance in standard version of 100mm to 800mm, larger on request
Transmission ratios freely selectable, up to 1:10 single-stage, up to 1:25 two-stage
Performances 50 kW to 30 MW, higher performance on request
Nominal torque Up to 100 kNm and more
Installation position Horizontal or vertical
BSR
Rotational speed Up to approx. 30,000 min-1
Circumferential speed max. 145 m/s
Standard type code ASR (A=single-stage, S=spur, R=Ratiopek)
BSR (B=two-stage, S=spur, R=Ratiopek)
Integral special models AVT (A=single-stage, V=half flange for attaching turbine or impeller housing & impeller
directly attachable to gearbox shaft, T=driven by turbine)
AVK (A=single-stage, V=half flange for attaching compressor housing & spiral directly attachable
to gearbox shaft, K=driven by a compressor)
Thrust collar version available for all models
Versions Wheel sets in double or single helical gearing, manufactured out of high alloy case-hardened
steels
All wheel sets are dynamically balanced. Single helical gearing can be realised with or without
thrust collars, for a highly stable operating performance the shafts are supported by low-mainte-
AVT
nance, split, two and four-surface friction bearings as standard, tilting pad bearings are fitted for
higher rotational speeds
Special versions External axial forces or those caused by the gearing can either be absorbed through combined
axial/radial bearings or separate special axial bearings (if required, with load compensation)
Gearboxes with low rotational speeds can be fitted with antifriction bearings made out of espe-
cially high quality materials
Seals on the shaft ends are normally fitted with non-contact labyrinth seals, special seals such as
slide ring seals or radial carbon ring seals are fitted for special applications
Lubrication All gearboxes require a pressurised oil lubrication and can also be connected to a central lubrica-
tion system, the oil pump can be flange-mounted to a free shaft end in the form of a gear wheel
or screw spindle pump and be directly driven by the gearbox
Separate pressurised oil lubrication when no central lubrication system is available
Options Monitoring facilities: Resistance thermometer, machine thermometer, oil pressure indicator,
