Title: Shigeyuki Ono: Innovator in Seal Devices and Universal Joint Boots
Introduction
Shigeyuki Ono is a notable inventor based in Ogasa-gun, Japan. He has made significant contributions to the field of mechanical engineering, particularly in the development of seal devices and universal joint boots. With a total of 5 patents to his name, Ono's innovations have enhanced the performance and reliability of various mechanical systems.
Latest Patents
One of Ono's latest patents is a seal device designed to suppress static leakage. This innovative seal device features a seal lip that slides in contact with a seal flange, which includes a thread groove that exerts a fluid pumping action during shaft rotation. This design effectively prevents sealing fluid from leaking between the housing and a rotating shaft. The seal lip is attached to the inner periphery of the shaft hole, while the seal flange is affixed to the outer periphery of the rotating shaft. The sliding area of the seal flange is a flat surface without thread grooves, and it has areas on both the outer and inner peripheral sides that contain thread grooves to enhance fluid pumping when the shaft rotates.
Another significant patent by Ono is for a boot for universal joints. This boot includes a bellows part and a ring-shaped mounting part at one end, designed to receive a cup for one of the two members that move relatively to each other. The inner peripheral surface of the mounting part features protrusions that extend toward the axial center, and the seal lip's height decreases from the bottom of the protrusion to the peak, while its width increases. This design improves the sealing performance of the boot, ensuring better protection for the universal joint.
