Title: Ryo Shiina: Innovator in Rotary Device Technology
Introduction
Ryo Shiina is a prominent inventor based in Kashiwara, Japan. He has made significant contributions to the field of rotary devices, holding a total of 4 patents. His innovative designs have advanced the functionality and efficiency of various mechanical systems.
Latest Patents
One of Ryo Shiina's latest patents is a rotary device that features a housing accommodating a shaft and a rolling bearing. This rolling bearing includes an outer ring attached to the housing, an inner ring that rotates with the shaft, a plurality of tapered rollers, and a cage. The design is configured to generate a pumping action that facilitates fluid flow with an axial component in the bearing annular space during shaft rotation. Additionally, the housing has a closed space on one side of the rolling bearing, except for the side adjacent to the bearing. The rolling bearing also incorporates an oil reservoir portion at the end of the outer ring, designed to store lubricant.
Another notable patent involves a method of assembling a tapered roller bearing, along with a jig for use in this method. In this assembly process, a cage assembly is moved axially to approach an inner ring from a small rib portion side. The inner ring assembly is formed by having the tapered rollers of the cage assembly climb over a small rib portion to fit onto the inner raceway surface, which is then assembled to an outer ring. A jig is utilized adjacent to the small rib portion, featuring recessed grooves that allow contact with the tapered rollers. This design enables the tapered rollers to slide radially outward, increasing the diameter of the cage and facilitating the assembly process.
