Schaeffler introduces quality standard for bearings used in wind power applications
Schaeffler has introduced a wind power standard (WPOS) for its rolling bearings used in wind power applications.
The company created the standard in response to the demands of multi-megawatt turbines, the development of which has led to higher forces and torques, meaning components are being subjected to ever-increasing loads. At the same time, any downtime or maintenance can be very costly, especially in the case of offshore plants.
Schaeffler claims that the new standard for products and processes enables it to ensure the high quality and reliability of its bearings and to offer customers the same quality as it is already providing in the automotive and aerospace sectors.
In future, the relevant bearings will be labelled with a ‘WPOS’ mark. It is expected that all Schaeffler bearings for wind power applications will be included in the WPOS standard by the beginning of 2014.
- Internal audits will monitor compliance with strict quality specifications that apply to all development and design teams, as well as for all of Schaeffler’s manufacturing locations worldwide that design and manufacture bearings for wind turbines.
- In order to ensure high standards are implemented, Schaeffler uses co-ordinated, transparent processes in close collaboration with customers and suppliers, with a defined change management structure, strict quality monitoring and comprehensive documentation.
- Selective supplier development ensures high levels of quality in terms of the quality of steel used, for instance.
- The design process involves product development in conjunction with customers and includes providing advice and guidance on selecting the correct bearing type, matching the bearing to the environmental conditions, designing the bearing while considering WPOS requirements and calculating the life, contact pressure and static factors of the bearing design.
Schaeffler’s Fiesta E-Wheel Drive concept car successfully competed against other electric vehicles in the fourth Silvretta E-Car Rally on 4–7 July 2013 in Montafon, Austria. The car finished ahead of other electric vehicles, some of which are already in volume production.
In this technical article, Dr Steve Lacey, engineering manager at Schaeffler UK, discusses the importance of selecting a special surface coating or corrosion-resistant material for rolling, plain and linear bearings operating in harsh food, beverage or packaging environments.
Schaeffler is offering its linear actuator and bearings for swivel drives as a complete system for photovoltaic (PV), concentrating photovoltaic and concentrating solar power systems. These systems operate more efficiently when their mirrors, collectors and PV modules accurately track the course of the sun during the day.
Schaeffler has supplied four spherical roller bearings with tapered bores to the Portland Valderrivas cement plant after the existing bearings in the company’s roller press reached the end of their service lives. Portland Valderrivas contracted an engineering service provider and Schaeffler showed its fitters exactly how to mount the bearings.
Schaeffler has worked closely with the steel industry to develop a high-strength quenched and tempered steel specifically for wind-turbine slewing rings that are subjected to extreme loads during blade and tower adjustment.
