Abstract

The invention relates to a double-row spherical roller bearing double-lip sealing structure and a wind driven generator, and belongs to the related technical field of wind power equipment. The double-row spherical roller bearing double-lip sealing structure mainly comprises an inner sealing ring; a pressing plate is arranged on the sealing ring; the inner side of the pressing plate is provided with a sealing ring body, a bearing end cover and a double-row spherical roller bearing body; the sealing ring body comprises a sealing ring body top which is connected with one end of a bent waist part, the other end of the bent waist part is in sealing connection with a vertical transition part, and the vertical transition part is connected with the bottom of the sealing ring body; and the lower surface of the bottom of the sealing ring body is provided with a first sealing lip and a second sealing lip. According to the double-row spherical roller bearing double-lip sealing structure and the wind driven generator, by improving a sealing ring body in an existing roller bearing sealing structure, the problems of sealing failure and leakage of the original sealing structure under special working conditions are effectively solved through the double-row spherical roller bearing double-lip sealing structure.

Description

technical field [0001] The invention relates to the technical field related to wind power equipment, in particular to a double-row spherical roller bearing double-lip seal structure and a wind power generator. Background technique [0002] The single-bearing structure of the main shaft bearing of megawatt wind turbines mostly uses double-row spherical roller bearings. Such as figure 1 As shown, the current sealing structure of this kind of bearing mainly adopts the skeleton sealing structure of single lip, which includes the inner sealing ring 1-1, the upper part of the sealing ring 1-1 is the pressure plate 1-2, and the inner side of the pressure plate 1-2 is the sealing ring 1-2. 3. Bearing cover 1-4 and double row spherical roller bearing body 1-5. [0003] Because the spherical roller bearing allows the main shaft to move radially relative to the bearing seat, when the wind wheel is subjected to a load that is not perpendicular to the main shaft, the main shaft will mo...
