The present invention relates to a rotational shaft assembly for a scissors type bucket apparatus and a scissors type bucket apparatus having the same, which employs a slidable rotary member that can be easily separated and replaced instead of a bearing permanently fixed to rotatably cross-link a pair of scissors arms, and minimizes the number of components and maximizes assembly characteristics. To this end, the rotational shaft assembly for a scissors type bucket apparatus comprises an installation pipe fixed to a first scissors arm; a rotary member including a bush fixed to the installation pipe and a rotary wheel installed to be slidably rotated relatively with respect to the bush; a central shaft coupled to penetrate through the rotary wheel, a second scissors arm, and an auxiliary arm such that the central axis can rotate together with the rotary wheel, the second scissors arm, and the auxiliary arm, and fastened to be aligned an end portion of a rotational shaft; a fixed ring shrink-fit to a gap formed between an outer circumferential surface of an end portion of the central shaft and the second scissors arm; a cover plate pressing the fixed ring from an outer circumferential surface of the second scissors arm such that the fixed ring is shrink-fit; a plurality of longer axis pins installed around the central shaft in a circumferential direction and penetrating the auxiliary arm, the rotary wheel, the second scissors arm, and the cover plate to bind them; and a pressing nut fastened to a front end portion of the longer axis pin to fix the longer axis pin and inducing the cover plate to press the fixed ring. |
