Abstract
PURPOSE:To carry out not only the cooling of a screw shaft but also the direct cooling of a ball nut itself and obtain a ball screw suited to high-speed and high-accuracy application by providing plural cooling fins which project outward on the outer periphery of a ball nut. CONSTITUTION:A cylinder body 10 having plural radially projecting cooling fins 9 is fitted on the outer peripheral part of a ball nut 1 increasing the radiating area by these cooling fins 9 to diffuse the generated hear on a nut 1 side by means of air cooling. Thereby, the ball nut 1 side on which generated heat is liable to accumulated can be effectively cooled, in a ball screw in which the cooling of only the screw shaft 3 side was conventionally carried out, thereby, stabilizing various characteristics such as the pre-load, rigidity value, life, etc., of a ball screw. Also, the thermal deformation of a feeding table 2 which is joined to a ball nut 1 can be prevented, obtaining a ball screw suited to high-speed and high-accuracy application.
