Designed to improve the reliability of large gearboxes used in wind power generators and other industrial machines, NSK has introduced a long-life, large-size roller bearing. The principal innovation of the new bearing is a combination of special heat treatment technology and proprietary NSK material that delivers superior flaking resistance, including that of white structure flaking. The result is seven times longer service life than that provided by a standard steel (SUJ2) bearing.
Bargteheide – Drives with advanced condition monitoring capabilities that support predictive maintenance have been showcased by NORD DRIVESYSTEMS at this year's Hannover Messe exhibition. NORD employs frequency inverters with an integrated PLC to monitor the complete drive system, evaluate sensor data, and assess the system state by means of intelligent algorithms. An industrial gear unit demonstrates the condition monitoring approach based on sensors and dedicated evaluation technology. Vibration and oil sensors provide crucial live data about the wear and tear. Vibration analysis then enables conclusions about the state of the bearings as well as the gearing, and oil analysis can help determine when the lubricant needs changing.
NORD DRIVESYSTEMS AC vector drives up to 90 kW have been certified by Underwriters Laboratories of Canada. This is in addition to the existing UL certification for the United States and allows for more efficient drive configuration for the North American market, because the additional line filter that was previously necessary for use in Canada is now no longer required. Users gain various benefits: cost savings, faster wiring, reduced space requirements, and simplified configuration. NORD offers a highly versatile range of drive electronics for all applications and industries, featuring a series of cabinet AC vector drives for motor outputs up to 160 kW and two decentralized inverter lines for field installation with models up to 22 kW. The intelligent controllers provide an integrated PLC, scalable functionality, and flexible interface options.
