Title: Hiroki Segawa: Innovator in Clutch Technology

Introduction

Hiroki Segawa is a notable inventor based in Fukuroi, Japan. He has made significant contributions to the field of clutch technology, holding a total of 4 patents. His innovative designs have advanced the functionality and efficiency of one-way clutches.

Latest Patents

One of Hiroki Segawa's latest patents is a unidirectional clutch. This invention includes an inner race, an outer race, and a plurality of cams that are interposed between the inner race's outer peripheral surface and the outer race's inner peripheral surface. These cams serve to transfer torque between the inner and outer races. The design also features a retaining mechanism that holds the plurality of cams in place, along with a spring member that biases the cams to torque non-transfer positions. The retaining mechanism consists of a first retainer fixed to the outer race, which has a cylindrical retaining portion that maintains the cams at a predetermined interval in a circumferential direction. Additionally, a second retainer is located on the inner diametrical side of the cylindrical retaining portion, allowing the cams to swing in a torque transferring direction when engaged with the inner race and outer race surfaces.

Another significant patent involves a method of manufacturing the outer retainer of a one-way clutch that includes windows. This method entails placing the outer retainer into a die and using a thin punch to punch out slits in the outer retainer. The process involves sliding the punch toward the axis of the outer retainer from the outer periphery-sided curve portion of the outward flange to the inner periphery-sided curve portion, utilizing a die and punch for precision.
