Abstract
A ball screw with maintenance device includes a screw shaft including a helical rolling groove; a nut having an outer circumferential surface in which at least two mounting holes is formed; two recirculation elements, which are mounted to the nut and each having a through hole having an open end set in a spacing distance from the rolling groove; a fixing cover mounted to the outer circumferential surface of the nut and includes a concentration trough formed therein. The through hole has an end communicating with the concentration trough. The concentration trough is connectable to a suction tube or an oil/grease supply tube. The suction tube can remove contamination from the interior of the nut through the through hole, and the part that has been cleaned up with the suction tube can be replenished with fresh oil/grease with the oil/great supply tube to achieve complete maintenance of the ball screw.
