Latest Patents
One of his latest patents is for a tapered roller bearing. This innovative design includes an inner ring with an outer circumferential surface featuring an inner raceway surface. The inner ring also has a cone back face rib portion that protrudes radially outward on its second axial side. The outer ring contains an outer raceway surface, and a plurality of tapered rollers are positioned between the inner and outer rings. An annular cage retains these tapered rollers, ensuring they are spaced from each other in a circumferential direction. The cage features a small-diameter annular portion and a large-diameter annular portion located on the second axial side, which includes an oil pocket with apertures for efficient lubrication.
Another notable patent is for a ball bearing. This design consists of an outer ring, an inner ring, and a plurality of balls, all held together by an annular cage. The cage allows oil to flow into the area between the outer and inner rings from one side in an axial direction, while facilitating outflow from the opposite side. The cage's annular portion is strategically designed to optimize oil flow, enhancing the bearing's performance.
