Abstract
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 tangential force, thereby effectively preventing the low repeated locating accuracy caused by an assembly crevice of the plugging.

In the technique scheme, described locating stud is a taper pin, and described positioning hole is a cone shape hole.
In the technique scheme, the small end of described 2 cone shape holes is on 1 circular planes of pivoting support outer ring simultaneously or is in respectively on 2 ring planes of pivoting support outer ring.
In the technique scheme, the parallel axes of described 2 cone shape holes or be different surface beeline.
In the technique scheme, described 2 cone shape holes all pass or part is passed pivoting support outer ring and obstruction.
The utility model working principle: after the steel ball of pivoting support and spacing block are put into the steel ball rolling channel of pivoting support via plugging hole, plugging hole is put in obstruction deviate from raceway to prevent steel ball or spacing block.Then 2 taper pins are put into the cone shape hole that passes pivoting support inner ring (or outer ring) and stop up respectively, will be stopped up tightening on the inner ring or outer ring of pivoting support.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
The utility model is by the use of two locating stud position structures, when making the obstruction of pivoting support be subjected to tangential force, no longer is subjected to displacement, and can effectively avoid because the low problem generation of repetitive positioning accuracy is caused in the fit up gap of stopping up.
