Title: The Innovative Contributions of Yoshito Oku
Introduction
Yoshito Oku is a prominent inventor based in Kyoto, Japan, known for his significant contributions to the field of fluid dynamic-pressure bearings. With a total of 14 patents to his name, Oku has made remarkable advancements in technology that enhance the efficiency and reliability of various mechanical systems.
Latest Patents
Among his latest patents is a fluid dynamic-pressure bearing device and spindle motor. This innovative design includes a rotatable shaft, a hub, a fixed portion, and a lubricating liquid. The hub features a thrust bearing surface that extends radially from the shaft, while the fixed portion includes an upper thrust bearing surface that faces the hub thrust surface. Together, these components form an upper thrust dynamic-pressure bearing. The design also incorporates an annular gap that is larger than the total axial dimension of the upper thrust gap and the average depth of the dynamic-pressure generating grooves. This configuration minimizes shaft loss and reduces the likelihood of lubricating liquid shortages or leaks.
Another notable patent is a small-size, small-height fluid dynamic-pressure bearing device that effectively reduces shaft loss and is less prone to issues such as lubricating liquid shortages. This design features a thrust dynamic-pressure bearing located at an inner position, with a slightly widened gap outside to retain lubricating liquid. An oil circulating path is also integrated into the design, enhancing the overall functionality of the device.
