Wind Turbine Bearings SKF - Nautilus bearing

      SKF Tapered bearing distributor in China editing, along with the development of wind turbines, wind power generators become the development trend of the market, and one of its main components bearing various suppliers also become the target relative to catch up. SKF Group in order to meet this goal developed for wind turbine SKF Nautilus bearing tapered roller bearings.

      SKF specially developed for high-power wind turbines large contact angle of tapered roller bearings Nautilus bearings. SKF Nautilus bearing for the back to back in the form of tapered roller bearings, with the larger the contact angle (45 °). SKF Nautilus bearing not only allow single bearing spindle configurations as possible, while greatly reducing the traditional design of the drive chain length so compact wind turbine designs. Of course, this design also ensures the bearing or drive all the features.

      SKF Nautilus bearing a remarkable feature is its use of a segmented plastic cage, segmented cage design, as each individual component is very small, and no intermediate links, even in the loaded state of the bearing will not affect the deformation of the shape of the cage and the rolling element guide. Also, because each component only four rolling, therefore, the holder will be generated by the friction is reduced to a minimum range. SKF Nautilus bearings of plastic, not only to ensure adequate strength, and its lighter weight to ensure the rotation of the bearing performance, while reducing the friction in the bearing, so that the application of more reliable and lubricating higher selectivity.

      In addition, the traditional pairing (or double row) tapered roller bearings, the contact angle is generally only about 20 °, while ensuring its larger radial load capability, bearing axial load carrying capacity and the ability to withstand the overturning moment subject to certain restrictions. SKF Bearing break through the traditional design of the contact angle, the contact angle of each single bearing enlarged to 45 °, in the bearing radial load capacity of the premise, greatly strengthened the axial load bearing capacity, while, SKF Bearings can also withstand large overturning moment. Configuration of the conventional double bearing comparison, SKF Nautilus bearing load is applied to two lines of intersection of the center line from the axis is much longer than the general configuration of tapered roller bearings, these two points of intersection on a point of the support shaft runs. But also to adjust the bearing preload condition to optimize the rigidity of the system.

      SKF Nautilus bearing as SKF Bearing Tapered Roller Bearing part of the sample. SKF Nautilus series bearings to improve wind turbine wind generator power at the same time, reduce their weight, reduce the manufacturing cost of the entire wind turbine for wind power producers who brought the most direct economic benefits.
