<p>The present invention relates to a coupling structure of a gear train to allow an automatic transmission to freely be installed in the frame of a crane as a plurality of gears linearly arranged in an axial direction of a rotary shaft are supported on one side and an other side of a radial rolling bearing in the axial direction, and a plurality of gears linearly mounted on the rotary shaft in the axial and radial directions to be rotated are reduced when compared to a conventional coupling structure of a gear train; and to make the radial rolling bearing support the plurality of gears in the radial direction of the rotary shaft in balance.</p> |
