Title: **Kazuyoshi Harimoto: Innovator from Iwata With a Focus on Connecting Rod Technologies**
Introduction
Kazuyoshi Harimoto is a prominent inventor based in Iwata, Japan, known for his significant contributions to mechanical engineering through his innovative designs and patents. With a total of 13 patents to his name, Harimoto's work is particularly noted for its emphasis on cost-effective and efficient manufacturing processes in connecting rod technologies.
Latest Patents
Among his latest innovations are two key patents: the connecting rod and bearing-equipped connecting rod. The design of the connecting rod assembly features a configuration of multiple separate rod segments, each comprising a big end portion, a small end portion, and an intervening shank portion. This unique assembly approach allows for easy and inexpensive manufacturability by laminating the rod segments together. Furthermore, Harimoto introduced a ring member that is press-fitted into the end portions of these segments, thereby forming a robust laminated structure equipped with shell-type bearings.
In addition, Harimoto has developed a novel rocking bearing designed to reduce costs while maintaining performance. This invention features a raceway formed on the inner periphery of an arcuate bearing ring, which houses rolling elements within pockets provided by a retainer. The use of pressed steel plates in the construction of the bearing ring not only minimizes material costs but also contributes to the lightweight and compact nature of the bearing design.
