Title: Kanetsugu Tsurutani: Innovator in Thrust Ball Bearing Technology

Introduction

Kanetsugu Tsurutani is a notable inventor based in Mie, Japan. He has made significant contributions to the field of mechanical engineering, particularly in the design of thrust ball bearings. His innovative approach has led to the development of a unique patent that enhances the functionality of these essential components.

Latest Patents

Tsurutani holds a patent for a thrust ball bearing, which includes a pair of races that make an eccentric revolving motion relative to each other. The races are designed with a plurality of opposed annular raceway grooves defined by an outer edge and an inner edge. Balls are received in the respective opposed pairs of raceway grooves. Each raceway groove features a groove bottom pitch circle diameter that is smaller than the amount of offset. The height of the inner edge from the bottom of the groove is set at a predetermined value, while the height of the outer edge is larger than that of the inner edge. This arrangement effectively prevents the contact ellipse of the ball from riding over the outer edge of the groove. Tsurutani's innovation is encapsulated in 1 patent.
