<p>The present invention relates to a drive apparatus using a pin rack, in which a main frame part, a main bar, a coupling piece, a connecting bar, a front/rear roller installation bar and a side surface roller installation bar are welded in a # shape and welded to occupy minimal space so space occupancy ration is minimized and a lower structure of the drive apparatus is stably maintained. Also, an installation bracket unit is installed on the connecting bar of the main frame part such that spaces at both sides of the main frame are secured and is assembled to the main frame part by a bolt and a nut to improve an assembly and an accuracy of a power transfer part. In addition, the power transfer part is installed at an inner part of a pair of installation brackets, a drive motor is installed in an available space of the both sides of the installation bracket, and because the drive motor is slantingly assembled in the installation bracket to maximally utilize limited space and install the drive motor and a portion of the drive motor protruding outward is minimized. Therefore, since an optimal frame structure is provided by the weldable main frame part, a bolt assembled to the main frame part and a nut assembling installation bracket part, components can be easily assembled and disassembled, an assembled state is solid and accurate and utilization of space is maximized.</p> |
