Title: The Innovations of Mitsuru Sugita

Introduction

Mitsuru Sugita is a notable inventor based in Inuyama, Japan. He has made significant contributions to the field of engineering, particularly in the development of bearing technologies. With a total of seven patents to his name, Sugita's work has had a considerable impact on the industry.

Latest Patents

One of Sugita's latest patents is a half bearing with grooves preventing leakage of lubricating oil. This innovative design constitutes a cylindrical plain bearing that supports a shaft for rotation when two half bearings are combined. The half bearing features two circumferential ends, each equipped with a plurality of circumferential grooves that extend substantially over the overall circumferential dimension. These grooves include portions located at both ends of the half bearing, each having a larger axially sectional area than the grooves formed in the load-bearing portion during shaft rotation.

Another significant patent is a bearing device for internal combustion engines. This device comprises a crankshaft made of steel that has not been subjected to surface hardening. The crankshaft's structure is mainly composed of pearlite with a pro-eutectoid ferrite fraction of at most 3%. It is processed to achieve a surface roughness of at most 0.8 μm. The bearings in this device contain an aluminum bearing alloy bonded to a back plate and include at least Si particles of less than 4 mass%. This design effectively suppresses early abrasion and scratches of the crankshaft, making it equivalent to or less than the abrasion loss of conventional DCI shafts.
