  • Ball screw with a circulating assembly
    Patent number: 8813596
    Abstract: A ball screw with a circulating assembly is disclosed. The circulating assembly of the ball screw is divided into a first circulating block and a second circulating block and can be assembled on the ball screw in such a method that the first and the second circulating blocks are assembled separately, so that the circulating assembly is applicable to the screw shaft whose helical groove doesn't extend to the shoulder portion thereof. In addition, the circulating assembly is limited in terms of an angle, and the relation between the first circulating block and the second circulating block is especially limited, so that the ball screw is applicable to the nuts with smaller outer diameter. Hence, the ball screw can be applied to both the nuts with smaller diameter and the screw shafts whose helical groove doesn't extend to the shoulder portion thereof.
