Patent number: 11835116Abstract: An inner circulation ball screw includes a screw shaft, a nut, and a return member. The nut is disposed on the screw shaft to form a load path with the screw shaft. The return member is disposed in an accessory slot of the nut to form a non-load path connected with the load path to form a circulation path for circulation of balls. The return member has a ball-discharging channel provided with one end connected with an ineffective thread section of the nut and the other end communicating with a ball-discharging hole of the nut. Therefore, the balls are allowed to move to the outside of the nut through the ball-discharging channel and the ball-discharging hole for preventing the balls from being stuck in the ineffective thread section, thereby solving the problems of high resistance and damaging to related accessories.Type: GrantFiled: November 21, 2022Date of Patent: December 5, 2023Assignee: HIWIN TECHNOLOGIES CORP.Inventors: Szu-Wei Yu, Chih-Ching Tsai, Shang-Hua Tsai
