Specifications

THB's pitch bearings allow the turbine blade to be indexed or positioned to optimize blade angle, depending on wind speed. Our yaw bearings allow the turbine nacelle to rotate into the wind and support the nacelle on the tower.

 

Types:Generally, yaw and pitch bearing structures are single row ball slewing rings four-point contact bearing and double row ball slewing ring four-point contact bearing. And both these two types of bearings can be further divided into bearings without gears, bearings with internal gears, bearings with external gears according to gear position.

 

Material and heat treatment

Rolling elements' material: GCr15 or GCr15SiMn bearing steel

Rings' material: 42CrMo

Value of notched bar impact work: less than 27J at -20oC

Hardness of rings: 55HRC~62HRC after hardening and quenching

Hardness of raceway: 55HRC~62HRC after hardening and quenching

Width of soft area: larger than plug diameter +35mm at the groove of the plug

 

Gear: involute cylindrical gear with radial modification coefficient x=+0.5; precision and modulus as ISO standard

Radial and axial clearance of yaw bearings: 0~50μm

Radial and axial clearance of pitch bearings: less than 0μm

Lubrication: through lubrication hole(screwed hole: M10×1)

Seal material: NBR

Spacer: self-lubricated spacers,which can compensate for lubrication when lubrication oil is unevenly distributed in order to maintain best lubrication status between balls and groove contact areas.

Cage: integrated steel cage which has simple structure and can save space and accommodate more balls to increase load capacity. Compared with traditional segmented cage, integrated cage is easier to assemble and more stable and reliable.

Preservation treatment: except for groove and gear all other surfaces should be applied thermal spraying anti-corrosion treatment according to ISO standard, when applied zinc coating, the thickness of anti-corrosion should be no less than 160μm, other anti-corrosive treatment shall be applied if it meets performance requirements of the machine.

 

Wind turbine applications:

Pitch and yaw

High and low wind speed

Land-based or offshore

800KW to 3.0 MW

Critical operating temps to -40oC
