Slewing gearing plugging spacing structure for wind driven generator

The utility model discloses a slewing gearing plugging spacing structure for a wind driven generator. The spacing structure comprises a slewing gearing outer ring, steel balls, seal rings, isolating blocks, a slewing gearing inner ring, a plugging, a plugging hole and locating pins. The plugging hole is disposed in an annular roller path of the slewing gearing inner ring or outer ring and is provided with the plugging inside; the slewing gearing inner ring or outer ring and the plugging are provided with two non-overlapping locating holes provided with the locating pins respectively; the axes of the locating holes form included angles of 30 degrees to 90 degrees with a circular ring-shaped plane of the slewing gearing inner ring or outer ring; and the plugging is fixed to the slewing gearing inner ring or outer ring through the two locating pins. By employing the two locating pins to locate the plugging, the spacing structure prevents the plugging of the slewing gearing from shifting when being applied a tang
