Title: Nobuo Iwatani: Innovator in Preload Measurement Technology
Introduction
Nobuo Iwatani is a distinguished inventor based in Kanagawa, Japan. He is known for his contributions to the field of preload measurement technology, particularly in rolling bearings. His innovative approach has led to the development of a unique apparatus that enhances the accuracy of preload measurements.
Latest Patents
Nobuo Iwatani holds a patent for a "Preload measuring apparatus of rolling bearing." This apparatus is designed to measure the preload of a rolling bearing and includes several key components. The bearing support is responsible for supporting a rolling bearing by holding both ends of a shaft inserted into the inner ring of the bearing. The pressurization device applies a predetermined weight in the axial direction onto the rolling bearing. Additionally, the excitation device generates vibrations through the drive of piezoelectric elements. A vibration sensor detects the vibrations produced on the rolling bearing, while the control section operates the excitation device to obtain the resonance frequency. This frequency is then used to calculate the preload of the rolling bearing before the predetermined weight is applied.
