Introduction

Yuhi Hirata is an inventor based in Osaka, Japan, whose patent work addresses the durability and performance of chain-drive systems. He is associated with Tsubakimoto Chain Company.

Latest Patents

Hirata is credited with 1 patent, titled “Chain.” The invention is designed to improve wear resistance, limit chain elongation, reduce vibration and noise, and increase drive efficiency. It uses link plates and pins, with sliding surfaces treated with a hardened layer containing specified metal carbides or nitrides. Where the chain uses bushings as sliding components, their sliding surfaces may also receive the hardened layer.

Career Highlights

Hirata’s documented patent contribution focuses on surface engineering for chain components. By applying hardened layers to pins and other components that slide against them, the design aims to reduce wear at key contact surfaces and support more reliable chain operation.

Collaborations

Hirata’s listed coworkers include Kazuyuki Ebinuma and Yusuke Saito. His patent is associated with Tsubakimoto Chain Company.

Conclusion

Yuhi Hirata’s patent reflects a practical approach to improving chain performance through wear-resistant surface treatments, with the goal of extending service life and making drive systems quieter and more efficient.
