In addition, the ball screw disclosed by the invention is simple to dismount and mount.

Description

technical field [0001] The invention relates to a ball screw and belongs to the technical field of mechanical components. Background technique [0002] The ball screw is a mechanical part that is driven by the relative movement of the nut and the screw. It has better mechanical transmission efficiency and is widely used. However, if the ball screw lacks lubrication for a long time, the friction between the nut and the screw may increase and the wear of the ball screw may be accelerated. [0003] Therefore, in order to avoid the above-mentioned technical problems, it is indeed necessary to provide a ball screw with improved structure to overcome the above-mentioned defects in the prior art. Contents of the invention [0004] In view of the above-mentioned technical problems, the object of the present invention is to propose a ball screw capable of continuous self-lubrication. [0005] The technical solution of the present invention is realized as follows: a ball screw, wh...
