wind power bearing bearing temperature

The bearing temperature are the main reason:

The first: whether the lubricating oil quality deterioration? If the viscosity of lubricating oil can also result in INA bearing temperature Slewing drives‍ rise

Second: bearing assembly if too tight, the gap will lead to inadequate flange bearing temperature rise;

Third: bearing assembly too tight will result in bearing temperature rise;

Fourth: Race rotation on the shaft or shell will result in bearing temperature rise;

Fifth: the bearing load is too large will result in bearing temperature rise;

Sixth: if the bearing cage or a rolling Double Row Ball Slewing Bearing‍ body broken words, will result in bearing temperature rise.
