Latest Patents

Kudou's latest patents showcase his ingenuity and technical proficiency. The first patent outlines a comprehensive manufacturing method for a drawn cup needle roller bearing with a seal ring. This method involves several intricate steps, including:

- Forming a seal ring by pressing a metal plate, creating an annular first intermediate material.

- Subjecting this material to burring, where a portion is bent to form an L-shaped cross-section, resulting in a second intermediate material with a cylindrical portion and an outward flange.

- Removing the outward flange to create a cylindrical third intermediate material.

- Finally, applying cold rolling techniques to refine the inner diameter, outer diameter, and cross-sectional shape.

The second patent describes the features of the drawn cup needle roller bearing itself, which consists of a shell with a raceway surface and inward flange portions. It includes a cage with multiple pockets and needles, allowing for free rotation along the raceway surface. The incorporation of a cylindrical floating seal ring enhances dimensional accuracy and optimizes lubricant control within the bearing.
