technology of slewing bearings in wind turbine generating

Extending Bearing Life in Wind Turbine Mainshafts With the growth of the U S wind industry and introduction of 1MW turbines higher loads and increased stresses are impacting mainshaft and gearbox bearing life Damage and failure modes are occurring sooner than expected and for many There are four common bearing design concepts for turbine rotor shafts The first is a two-point suspension with a toroidal roller bearing on the rotor side and a spherical roller bearing on the generator side This is used for turbines in the 6-MW category for example

Most wind turbines are designed to run at slow rotor speeds hence gearboxes are employed to transfer the torque from a slowly rotating input shaft (25–35 r p m ) to a high-speed output (1500–1800 r p m ) suitable for the AC generator A schematic of a wind turbine gearbox from Musial et al is shown in figure 16 The low-speed stage of

Slewing ring also known as slewing bearings or turntable bearing is a large bearing which is able to sustain the more axial load radial load and tilting moment It is known as: "machine joints" the essential machinery transmission parts between the two objects that need to be relative rotary motion
