为了适应传递功率不断增大的需求，Flender Graffenstaden的R&D研发部门的专家、机加工的专家、质检专家和设计工程师组成的团队提供被认证的设计与制造工艺，来保证Flender Graffenstaden生产的设备在依旧高可靠性的前提下传递的功率更大，即使在非常高的功率及节圆线速度情况下。附上高强度的焊接与铸造箱体。Flender Graffenstaden齿轮箱设备可以根据技术文件的需求，在转子轴的自由端装上一台润滑油泵或者盘车装置。

For more than 60 years, Flender Graffenstaden is recognised as the world leader for Gearboxes used in Industrial Power Generation applications including either gas turbine or steam turbine driven generators.

Load Gear units are designed based on API or AGMA standard, and optimized in order to offer the maximum efficiency.

Each product is tested individually on one of our state of the art test bench at full speed, no load condition, partial load test or even back to back locked torque test.
Flender Graffenstaden also manufactures auxiliary gear units used on some of the most common design of Gas Turbines for starting and driving the auxiliary equipment such as compressors, oil pump etc…

Flender Graffenstaden High Performance gear units are used in all processes of the Oil & Gas industry throughout the world :.

Upstream : FPSO’s, Platforms, Onshore fields

Midstream : Pipeliners, LNG tankers

Downstream : Refineries, LNG plant, GTL plant

Petrochemicals : Fertilisers, PTA plant

For those applications, gear units are generally designed based on API 613, and are tailored to customer’s specifications – end users, engineering contractors, and OEM’s. Flender can accommodate mechanical running test at full speed full load, partial load test or even back to back locked torque test.

With an installed fleet of more than 13 000 high speed gearboxes and more than 60 years of experience, Flender Graffenstaden will become your alliance partner for the maintenance of your equipment at the highest technological level of performance and durability.

With our international presence, we have a team of highly skilled service engineers available when you need them.
Customer support is at the heart of Flender Graffenstaden’s philosophy.

Through a long history of gear manufacturing, Flender Graffenstaden has acquired the know-how and the experience to be a leader in the field of high speed gears. The industrial site of Strasbourg (France) has developed a tradition in high performance gear units for more than 60 years and through 13 000 references for the Power Generation and the Oil & Gas industries (speed reducer or increaser, auxiliary and special gearboxes)

Based on an experience of more than 12 000 thousands gear units, Flender Graffenstaden manufactures high efficiency gear units used in all processes in power plants, refineries, offshore and onshore oil and gas installations, petrochemical and industrial process plants around the world.
Flender Graffenstaden provides turbo parallel shafts and integral gear units with centerline distances ranging from 150 to 1500 mm. Designed to meet specific customer needs, our products can reach rotation speeds up to 40000 rpm and powers up to 100 MW.

In order to transmit these high powers, our case hardened and nitrided teeth are grounded with optimized corrections to ensure homogenous load distribution in operation and provide high reliability during the entire service life of the product. In addition to high precision manufacturing and control standards, each gearbox benefits from a dynamically optimized design of shafts and hydrodynamic bearings. Based on the most modern technologies and latest knowledge in the field of gearboxes, every single gear unit is tested in our facility to demonstrate satisfying operation while highly reliable instrumentation is installed to enable efficient monitoring on-site.

 
INTEGRAL GEAR UNITS

For industries looking for high efficiency compression systems, Flender Graffenstaden provides single or multiple meshing integral gear units using single helical and thrust collar designs. With impellers directly mounted to the gear casing, these products form an integral unit with the driven compressors and expanders (integrally geared compressor).
These multi-stage gear units can also incorporate other machines such as electric motors, steam, gas turbines, coolers and turboexpanders.
Using the latest knowledge in vibration analysis, journal and thrust bearing technology, sealing systems, finite element calculations for both shafts and casing and the know-how acquired over 60 years of gear manufacturing, Flender Graffenstaden now provides integral gear units weighting over 50 tons and wheel diameters reaching 3 meters for process plants.

TURBO GEAR UNITS

Driven by gas turbines, steam turbines or electrical motors, our single and double helical turbo parallel shaft gear units are preferred by professionals in search of high power transmission with very low power losses.
To accommodate the constantly increasing transmitted powers, our R&D experts, manufacturing professionals, quality specialists and design engineers team provide qualified design and manufacturing processes, ensuring the production of more powerful but still reliable gear units even at very high powers and pitchline velocities. 
Enclosed in rigid welded steel or cast iron casings, Flender Graffenstaden gear units can be equipped with a lubricating oil pump or a turning device connected to the free shaft ends of the gear train, according to specific needs.
