The utility model relates to a device for ball screw transmission for machinery technical field. It includes lead screw and transmission sub-assembly, the transmission sub-assembly includes nut overcoat and holder, surface machining becomes the smooth surface in the nut overcoat, processing has a through-hole on the said holder, and the holder expandes the integral multiple that through-hole centre-to-centre spacing that the back corresponds is lead screw pitch, the smooth surface and the after-fixing of holder surface connections of said nut overcoat are provided with the steel ball in the through-hole, the position of through-hole keeps unanimous with the circulation of the raceway of lead screw, forms the transmission sub-assembly, on the transmission sub-assembly is provided with drive gear, the lead screw passes the holder and passes through raceway and steel ball connection on the lead screw. Rotation and linear motion's conversion between transmission sub-assembly and the lead screw can be realized to this device, and it is little to rub in addition, high transmission efficiency, and small in noise has improved life, has saved the cost, and the suitability is strong in addition, has liberated the labour greatly, has improved production efficiency
