Latest Patents
Yamada's latest patents include advanced designs for ball screw devices. One notable patent describes a ball screw device that features a circulation path for returning balls from the endpoint to the start point of the load path. This design incorporates a return path, scooping paths, and connecting paths. The scooping path is characterized by an arc-shaped center line that curves outward in the radial direction as it approaches a reference imaginary flat plane. This plane includes the center axis of the screw shaft and the center line of the return path in the circumferential direction. The connecting path is arranged on this reference plane and consists of a straight path with a linear center line extending orthogonally to the center axis of the screw shaft. The design ensures that the radius of curvature of the scooping path, the scooping angle, and the length of the straight path are optimized for effective ball circulation.
Another patent focuses on a ball screw device that includes a screw shaft, a nut, a circulation part, and balls. This design features a housing concave groove on the outer circumferential surface of the nut, which extends linearly in the axial direction. The circulation part is strategically arranged within the housing groove to prevent radial displacement while allowing circumferential movement. This innovative design enhances the functionality and reliability of ball screw devices.
