Now why the wind power gear box are not spherical roller bearings, tapered roller bearings and all tend to use?
The bearing load is not the same type, spherical roller bearings are generally suitable for coarse, can withstand axial load where the radial, can withstand axial impact load, but he is not sensitive to axial impact load, and when the inner ring and stick rotation relative to the axis of the outer ring, will lead to the dynamic eccentricity, not concentric, will slide.Paired cone type X arrangement, also can withstand the axial load where the radial axial load, also can withstand the axial load and the internal reverse, can compensate each other, suitable for high-speed operation, as the axis fixed end configuration, but to the adjustment of internal clearance requirements is very high, it can be said that he used to adjust the amount of success mainly depends on in the gap.
