Title: Yuichi Nishitani: Innovator in Shaft Coupling and Rotation Apparatus Technologies

Introduction

Yuichi Nishitani is a notable inventor based in Obu, Japan. He has made significant contributions to engineering, particularly in the fields of shaft coupling structures and rotation apparatuses. With a total of 3 patents to his name, Nishitani continues to push the boundaries of innovation.

Latest Patents

One of his latest patents is a shaft coupling structure that features a unique design. In this structure, a first shaft and a second shaft are coupled using a combination of a key coupling and a clamp coupling. The first shaft includes a cylindrical portion for the insertion of the second shaft, along with slits formed in the cylindrical portion. These slits are created by cutting portions of the shaft in the axial direction. A clamping fastener is mounted on the outer circumference of the first shaft where the slits are located, allowing the slits to also function as a keyway for the key. The design includes multiple slits arranged in the circumferential direction.

Another significant patent involves a rotation apparatus that includes a motor and a speed reducer. This speed reducer consists of a casing, an internal gear integrated with the casing, and a planetary gear that engages with the internal gear. A carrier body is positioned in the axial side of the planetary gear. The motor and speed reducer are connected through an adapter, which features a motor-fixed surface, a carrier-fixed surface, and an externally fixed surface that is not parallel to the carrier-fixed surface. The driven member is connected to the casing and is designed to rotate within a range of 180 degrees.
