Title: Yusaku Nakazono: Innovator in Sealing Technology
Introduction: Yusaku Nakazono is a notable inventor based in Tokyo, Japan, recognized for his contributions to sealing technologies. With two patents to his name, Nakazono has demonstrated a commitment to enhancing the functionality and reliability of sealing devices in various applications.
Latest Patents: Among Nakazono's latest innovations are two significant patents focusing on sealing devices. The first patent involves a unique sealing device designed to suppress the degradation of sealing properties due to the conduction of heat generated by the movement between a resin-made sealing member and a rotating shaft in conjunction with a rubber-made sealing member. This sealing device incorporates a rubber sealing member, a resin sealing member, a support ring, and a case. The support ring features both a large diameter portion with an inward flange, which secures the component to the case, and a small diameter portion that interacts with the rubber sealing member's lip, ensuring enhanced performance under thermal stress.
The second patent presents a lip type seal, which includes a cartridge fitted to the inner periphery of a shaft hole, a first lip seal member, a case, a second resin lip seal member, a backup ring, and an adapter. An innovative design feature includes a protrusion section on the case's first flange, designed to engage with the second lip seal member, preventing it from whirling and potentially detaching. This dual-layer protection is further secured by a projecting section on the backup ring, ensuring that the lip seal remains in place under dynamic conditions.
