Abstract
A circulating assembly for a ball screw comprises a cassette and a separator. The fitting hole of the cassette facilitates the installation of the balls, and the separator is inserted in the fitting hole of the cassette, and the sub-return path in the front end of the separator cooperates with the main return path of the cassette to smoothly guide the circulation of the balls, so that the balls can be installed easily and quickly. And the helical groove of the screw doesn't need to extend to the shoulder portion thereof.
