Title: Daijiro Kitahara: Innovator in Rolling Bearing Technology
Introduction
Daijiro Kitahara is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of rolling bearing technology, holding a total of 7 patents. His innovative approaches have led to advancements in the design and manufacturing of preload-adjustable rolling bearings.
Latest Patents
Kitahara's latest patents include a groundbreaking method for preload-adjustable rolling bearings. This assembly method involves several steps, such as providing a shaft with a first inner raceway and an inner ring that is press-fitted onto the shaft. The design ensures that the pitch of both raceways is greater than what is required to achieve a predetermined preload. Additionally, the method incorporates an outer ring with outer raceways and a plurality of balls positioned equidistantly in the circumferential direction. The rolling bearing unit is vibrated using piezoelectric elements while the inner ring is moved axially. This innovative approach allows for the measurement of the resonant frequency of the rolling bearing unit with a vibration sensor, enabling precise control of the preload. The inner ring can be pressed onto the shaft with minimal energy, preventing any scratching of the raceway and rolling surfaces.
