Title: The Innovative Journey of Makoto Shibata

Introduction

Makoto Shibata, an accomplished inventor based in Aichi, Japan, has made significant contributions to the field of engineering with a total of 8 patents to his name. His innovative work is primarily focused on improving the functionality and efficiency of sliding bearings, which are essential components in various mechanical applications.

Latest Patents

Among his latest patents is a groundbreaking design for a sliding bearing and a method of manufacturing the same. This invention outlines a cylindrical sliding bearing that can effectively support a rotational shaft by utilizing a sliding surface, specifically the inner circumferential surface. Notably, the design includes a crowning with a sloped surface at both ends of the sliding surface in the axial direction. This crowning mechanism is defined by a first crowning formed from the sloped surface of a lining layer and a second crowning formed from the sloped surface of a back metal positioned beneath the first crowning. This innovative approach ensures the crowning does not contact the rotational shaft unevenly, a common issue with conventional sliding bearings.

Another notable patent details a design featuring a helically continuous projection formed around the sliding surface of the bearing at a specified pitch. The surface roughness of this sliding surface, which includes the projection, is meticulously chosen to be no greater than half the height of the projection. This design attribute significantly enhances the running-in performance of the sliding bearing, making it a valuable advancement in bearing technology.
