<p>A supporting structure of a planetary gear speed reducer having shifted tooth profile is provided to support a rotating ring gear in order to prevent the output axis from being shaken. A supporting structure of a planetary gear speed reducer includes a guide block(410) connected to the peripheral part of circular ring gear(240); a first guide hole formed at the connection part or adjacent part between a stationary ring gear(230) and a circular ring gear; a second guide hole formed at the connection part or adjacent part between a guide block and the circular ring gear; a bearing driver(440) which is installed to be connected to the guide face of a second guide hole and a first guide hole; an axis penetrating hole(450) formed penetrating to a specific direction in the stationary ring gear and guide block; a volt through hole(460) which is formed to be connected with the axis penetrating hole; a guide axis(470) installed through the axis penetrating hole; and an axis fixing bolt(480) combined in the stationary ring gear and the guide block.</p> |
