High Speed Turbogears

The high-speed series of gearboxes comprises:

• Parallel shaft gearboxes with horizontal axes (single and multi-stage) and vertical axes i.e. series GB, G, GN, GS, SG.
• Planetary gearboxes with rotating or stationary planet carrier.
• MULTICOM multiple output shaft gearboxes for driving compressors
• MAAG Original Synchronizing clutch couplings

Experience and Technology: More then 100 years of gear manufacturing experience.

Close collaboration with our customers and constant involvement in their many and varied requirements has kept us at the leading edge technically and competitive in terms of price, quality and performance. Down through all these years, the experience and new technical know-how gained have been immediately applied to our designs. This has led to custom-made high performance gearboxes that give enduring service all over the world.

The main applications are drivers for:

• Centrifugal compressors
• Axial compressors
• Generators
• Pumps

Irrespective of whether the gearboxes are intended for compressor, generator or pump drives, we have always welcomed – and will continue to welcome – the challenge of finding an optimum solution for our customers.

Technology

The increasingly exacting requirements of gearbox design have also involved ever increasing pitch line velocities. Pitch line velocities exceeding 220 m/s have been achieved during back-to-back testing of gearboxes developed for basic research. These gearboxes transmit about 30 MW at pinion speeds of 16,000 rpm.

The knowledge and experience gained in these processes have led to the development of:

• Optimized centre distance and face width.
• Great design flexibility and rapid adaptation to customer requirements
• Radial bearings developed and tested by Maag on our own test bed enhance the acknowledged high reliability of our high performance gearboxes.
• High efficiency and hence low lubricating oil requirements that bar any comparison.
• Separate axial and radial bearings.
• Single or double helical gears.
• Gear cases hardened by the CARBOMAAG process.
• Gears precision-ground on the world's most accurate gear-grinding machines; With longitudinal and profile tooth-flank modifications compensate for the previously computed operational deformations under load so as to obtain an optimum tooth-contact pattern.
• A quality assurance system based on the requirements of the ISO 9001 standard embraces all activities. Standard and also the environmental responsibility of ISO 14001 embraces all activities.
