The bearing roller can be customized with different length and outer diameter according to customer requirements. Bearing rollers are available in a variety of designs, series, variants and sizes. The main design differences are the row number of rollers and the design and materials of inner/outer ring flanges and cages. The bearing can meet the challenges of radial heavy load and high speed. Adapted to axial displacement, they provide high stiffness, low friction and long service life.
The bearing rollers are also available in sealed or split designs. In sealed bearings, the rollers are protected from contamination, water and dust, keeping the lubricant inside and removing the contamination. This results in lower friction and longer service life. Split bearings are mainly used for bearing arrangements that are difficult to reach, such as crankshafts, and bearing rollers simplify maintenance and replacement.
Bearing rollers Develop high durability roller bearings to continuously improve the performance of wind turbine gearbox bearings
The high durability bearing improves the torque power density of the wind turbine gearbox, reduces the bearing and gear size by up to 25% by increasing the bearing rated life, and avoids early bearing failure by improving reliability. Bearing roller high durability wind turbine gearbox bearings rely on an optimized combination of custom steel and heat treatment processes to improve fatigue resistance and reliability. This optimized chemical heat treatment process improves the bearing surface and subsurface characteristics.
The heat treatment process of wind power gearbox improves the surface material performance of bearing parts, improves the material strength of the surface layer and below the surface layer, and can effectively cope with the high stress application conditions during the bearing operation. The performance of rolling bearings is very high. Much depends on raw material parameters, such as microstructure, residual stress and hardness.
This customized steel and heat treatment process has several advantages: increase the rated life of the bearing, and reduce the bearing size of the bearing roller under the same operating conditions; The bearing capacity of new bearing rollers is increased to resist typical failure modes of gearbox bearings and early bearing failure modes, such as white corrosion cracks, pitting corrosion and wear. Bearing roller
The internal bearing bench test and calculation show that the bearing life is increased by 5 times compared with the current industry standard. In addition, internal bearing bench testing also showed a 10 fold increase in resistance to early failures due to stress. The improvement of the bearing roller performance of the high durability gearbox means that the bearing size can be reduced, which is helpful to improve the torque power density of the gearbox. This is crucial for the design of a new generation of large megawatt multistage wind turbine.
