Title: Takayuki Miyagawa: Innovator in Pulley and Bearing Technology

Introduction

Takayuki Miyagawa is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of mechanical engineering, particularly in pulley and bearing technology. With a total of 4 patents to his name, Miyagawa's work has had a notable impact on the industry.

Latest Patents

Miyagawa's latest patents include a pulley rotation support apparatus designed to enhance the functionality of driven pulleys. This apparatus utilizes a three-point-contact-type or four-point-contact-type radial ball bearing. The design incorporates an offset quantity, which is an axial-direction distance between the center of a radial load applied from the endless belt to the driven pulley and the center position of the radial ball bearing. This offset is set to 40% or less of the pitch circle diameter of the radial ball bearing, ensuring optimal performance. Additionally, the radial clearance of the bearing is maintained at 0.2% or less of the pitch circle diameter.

Another significant patent involves a rolling bearing that addresses the frequencies generated by undulations on the inner and outer ring raceways and the rolling surface of the balls. This innovation ensures that the frequencies do not coincide with the rotational frequency of the supported rotation member. As a result, the rolling bearing exhibits minimal abnormal vibration and noise, even when used at low temperatures, thus enhancing its durability.
