Title: Yuichiro Hirai: Innovator in Damper Device Technology
Introduction
Yuichiro Hirai is a prominent inventor based in Okazaki, Japan. He has made significant contributions to the field of damper device technology, holding a total of 10 patents. His innovative designs have advanced the functionality and efficiency of various mechanical systems.
Latest Patents
Hirai's latest patents include a damper device that features a dynamic damper coupled to a first intermediate member. In this design, first and second inner-side springs, which act in series, are straight coil springs positioned between a second intermediate member and a driven member. This configuration restricts the outward movement of the springs in a radial direction, creating a gap between each body portion of the springs and the second intermediate member or the spring abutment portion of the driven member. Another notable patent describes a dynamic damper coupled to an intermediate member of a damper device. In this design, a drive member has additional abutment portions that are coupled to the end portions of vibration absorption springs before the first and second inter-element stoppers operate. The second inter-element stoppers engage before the first, ensuring that the additional coupling portions are effectively connected to the vibration absorption springs.
