Small Wind Turbine Generator (ALEKO WG400) Evaluation

I used grease and applied a small amount to the spindle, the bearings inner race and the inside of the stator. The reasseled turbine now spins much easier than oem. The oem spin was very tough. It took a little torque to get it to turn. Now with the greased components it spins with my hand turn and continues to spin!

Design and Development of a High Efficiency Air Turbine

Jun 07, 2019· Figure 11 shows the power output of the turbine and frictional power consumption of the spindle bearings over a range of speeds. The friction power of the spindle bearings is clearly quite significant, consuming over 40 W of power at 90,000 rpm. This is likely due to the large increase in bearing preload at high speeds.

Bearing arrangements for wind turbine main shafts | SKF | SKF

Different turbine manufacturers have different design philosophies that influence which bearings they use. One set-up is ‘loing and non-loing’, which uses two separate bearings on the main shaft. A loing bearing is exposed to both radial and axial loads, while a non-loing bearing accommodates only radial loads.

Technical principles - Schaeffler Group

On a shaft supported by two radial bearings, the distances between the bearing seats on the shaft and in the housing frequently do not coincide as a result of manufacturing tolerances. The distances may also change as a result of temperature increases during operation. These differences in distance are compensated in the non-loing bearing.
