摘要： A preload adjusting device for a ball screw is disposed between screw nuts of a ball screw and comprises: two preload pieces each formed at a side thereof with a slant surface. The two preload pieces are mounted between the screw nuts in such a manner that the slant surfaces of the two preload pieces abut against each other, by such arrangements, a combined thickness of the two preload pieces will be changed by a relative displacement between the preload pieces, and in this way, a preload between the screw nuts is adjusted.
