Cylindrical roller bearings are very often used because of their high radial load capacity. The ability to accommodate angular misalignment is limited and has to be considered according to the manufacturers guidelines. The bearings with black oxide-coated offers protection at corrosion and substances, thus they have a good behavior at harsh environments.

Appropriate condition for axial loading is achieved when the axial to radial load ratio Fa/Fr is less than 0.4 and viscosity ratio κ is higher than 2.

Spherical roller bearings

  • Suitable for large radial loads and low to medium speeds;
  • Allows compensation for misalignment;
  • Usually for main shafts and gear;

Spherical roller bearings have a high radial loading capacity and can accommodate a higher degree of misalignment. The experiences in wind turbine gearboxes are at the time not unambiguous. Consequently the operating conditions such as the ratio Fa/Fr, and the ratio between roller diameter and roller length, low radial loads as well as the risk of a considerable amount of skidding has to be carefully evaluated.

Advanced rating life (Ladv)

The method to determine rating life Ladv is described in DIN ISO 281 Beiblatt 4/ ISO/TS 16281:2008.

The main influences that shall be considered in an advanced life calculation are:

  • Radial, axial, and moment loads;
  • Load sharing between rolling elements;
  • Load distribution along the roller length considering actual roller and raceway profiles;
  • Load distribution on flanges of bearings;
  • Elasticity of bearing, shaft and housing;
  • Internal design of the bearing, hereunder roller and raceway profiling;
  • Truncation of contact area;
  • Operating misalignment between inner and outer rings;
  • Operating internal clearance considering initial clearance, shaft and housing fit, and temperature of inner and outer rings;
  • Operating lubricant viscosity and required lubricant viscosity for full hydrodynamic lubrication condition;
  • Operating lubricant cleanliness;
  • Performance of additive package;
  • Such advanced methods shall be used in the design phase of a wind turbine gearbox. The advanced rating life shall be greater than the specified design life of the wind turbine.
