Title: Kazuyuki Ichikawa: Innovator in Constant-Velocity Joints

Introduction

Kazuyuki Ichikawa is a prominent inventor based in Okazaki, Japan. He has made significant contributions to the field of mechanical engineering, particularly in the design and functionality of constant-velocity joints. With a total of 9 patents to his name, Ichikawa's work has had a substantial impact on automotive and machinery applications.

Latest Patents

Ichikawa's latest innovations include a sliding-type tripod-shaped constant-velocity universal joint. This design allows for a reduction in size while minimizing induced thrust force. The joint features an outer race, a tripod with a boss portion and three tripod-shaft portions inserted into roller grooves, and rollers. Notably, the width of the tripod-shaft portions decreases from the root side to the leading-end side in the torque transmission region. Additionally, the torque-transmission-wise width increases in the same region, enhancing its performance.

Another significant patent is the constant velocity joint itself, which comprises an outer race, an inner race, balls, and a cage. The outer race has a partially spherical inner surface with multiple outer ball grooves, while the inner race features a corresponding partially spherical outer surface. The design ensures that the radial distance of the outer ball grooves from the rotational axis increases toward the opening end, optimizing the joint's functionality.
