Title: Yuzuru Sanbongi: Innovator in Friction Technology
Introduction
Yuzuru Sanbongi is a notable inventor based in Hokkaido, Japan. He has made significant contributions to the field of friction technology, holding three patents that showcase his innovative approach to solving complex engineering challenges.
Latest Patents
One of his latest patents is the Hard-faced friction mating member. This invention involves a friction mating member that is fabricated by providing a surface of a base member with a hard coating. This coating has a load point displacement characteristic where the elastic range, defined as the ratio of elastic deformation to maximum indentation depth, is at least 50% in a load range from 1 to 50 mN. The friction mating member is designed to cope with both an increasing friction coefficient in a high-speed range and a decreasing friction coefficient in a low-speed range, without being affected by the type and deterioration of the lubricating oil. Additionally, it maintains an m-V characteristic with a positive gradient over a long period of use, effectively addressing issues related to noise and vibration.
Another significant patent is the Wet friction disc clutch. This invention utilizes different patterns and sizing of the oil dispersal grooves of interleaved toothed discs. The design promotes the removal of oil from the friction material, particularly from the disc that rotates at a lower speed, enhancing the overall efficiency of the clutch system.
