Latest Patents
Kubo's latest patents include innovative designs for high-speed rotating apparatuses. One of his patents describes a high-speed rotating apparatus having a face-to-face angular contact ball. This invention features a combination of two angular type ball bearings arranged face-to-face, where the diameter of the balls in the second bearing is smaller than that of the first. This design allows the ball bearing unit to support a substantially unidirectional axial load at high speeds, with a pitch circle diameter and rotating speed range of 800,000 to 3,000,000 mm.rpm. The radial load can be up to one-fifth of the axial load.
Another patent by Kubo involves a high-speed rotating apparatus with face-to-face contact ball bearings. This design also utilizes two angular type ball bearings in a face-to-face arrangement. It is engineered to support a unidirectional axial load while optimizing the contact angles of the bearings to enhance fatigue life and improve the endurance of the rolling bearing unit. The parameters for this invention include a pitch circle diameter and rotating speed range of 700,000 to 2,000,000 mm.rpm, with the radial load being up to twice the axial load.
