Latest Patents

One of Tsuchida's latest patents is for a multipoint contact ball bearing. This design is constructed to prevent damage to the rolling surfaces of the balls while ensuring durability and maintaining radial load capacity. The inner raceway features a complex curved surface, including a pair of side surface sections with a generating line shape that has a radius of curvature larger than 50% of the ball diameter. Additionally, the inner raceway bottom section connects the inside end edges in the width direction of the side surface sections, featuring a concave curved surface with a generating line shape that has a radius of curvature less than 50% of the ball diameter. The edges of both sides in the width direction of the inner raceway bottom section and the inside end edges of the inner raceway side surface sections are smoothly continuous, with finishing performed on both sections.

Another notable patent is for a ball bearing and supporting construction. This invention includes an inner ring fitted on a rotational shaft, which features an inner ring raceway on its outer circumferential surface. The outer ring includes an outer ring raceway on its inner circumferential surface, with a plurality of balls rotatably provided between the two raceways. A crown resin cage retains the balls at equal intervals in a circumferential direction. The bore diameter of the inner ring is 100 mm or more, and the radial clearance results in a state where the inner ring is assembled to the rotational shaft at 20 µm or more.
