Title: Shouta Toho: Innovator in Tapered Roller Bearings

Introduction

Shouta Toho is a notable inventor based in Kuwana, Japan. He has made significant contributions to the field of mechanical engineering, particularly in the design of tapered roller bearings. With a total of 2 patents to his name, Toho continues to push the boundaries of innovation in his industry.

Latest Patents

Toho's latest patents focus on advanced designs for tapered roller bearings. The first patent describes a tapered roller bearing featuring an inner ring guidance design. This design includes a smaller diameter annular part of a cage and a smaller rib of the inner ring, which defines a smaller diameter-side clearance S. Additionally, a larger diameter annular part of the cage and a larger rib of the inner ring define a larger diameter-side clearance S. The bearing establishes a dimensionless number Y, which ranges from at least 0.39 to no more than 0.88, according to the equation: Y=(S/S)×(d/l).

The second patent also pertains to a tapered roller bearing, where a dimensionless number X is defined based on the small-diameter-side gap S, which is the gap between a small-diameter-side annular part of a retainer and a small collar part of an inner ring. It also considers the large-diameter-side gap S, the average roller diameter d, roller length l, and an outer member angle α. The dimensionless number X is specified to fall within the range of 0.69
