The invention discloses a wind turbine generator main bearing seat capable of inhibiting wind wheel vibration transmission, and relates to the technical field of bearing seats. The wind turbine generator main bearing seat comprises a sliding rail, wherein first limiting blocks are fixedly connected with two ends of the sliding rail; a wind turbine generator main bearing seat body is slidably connected with the surface of the sliding rail; buffering blocks are fixedly connected with the surfaces of the first limiting blocks; first buffering cavities are formed in the buffering blocks; second buffering cavities are formed in the first buffering cavities; and first spring rods are fixedly connected with the inner side walls of the first buffering cavities. The wind turbine generator main bearing seat body is capable of moving, so that the mounting and dismounting operation can be facilitated; the vibration reducing measures are taken at the front and rear parts, so that the influence of wind wheel vibrations on a cabin and the tower drum can be effectively reduced; and meanwhile, the fan vibration load is weakened and the temperature of vibration reducing equipment is kept within a safe range through a heat dissipating device in the vibration reducing process, so that the situation of heat fading can be effectively avoided, the device buffering effect can be guaranteed, and the bearing seat service life can be prolonged.
Description
technical field [0001] The invention relates to the technical field of bearing housings, in particular to a main bearing housing of a wind turbine for suppressing vibration transmission of a wind turbine. Background technique [0002] The bearing seat is used to make the shaft run in a circle and support the shaft. The conventional usage is two or more bearings. Its function is to make the shaft run normally, and the bearing seat is used to support the bearing and fix the outer ring of the bearing. , only let the inner ring rotate, the outer ring remains stationary, always keep in line with the direction of transmission, and keep the balance. A sliding bearing housing, comprising a bearing housing main body, a protective shell is provided on the outer surface of the upper end of the bearing housing main body, an adapter sleeve is provided on the inner outer surface of the protective housing, and an adapter sleeve is provided on the rear end outer surface of the adapter sleev...
