Title: Eri Watabe: Innovator in Rolling Bearing Technology
Introduction
Eri Watabe is a prominent inventor based in Fujisawa, Japan. She has made significant contributions to the field of rolling bearings, holding a total of three patents. Her innovative designs focus on enhancing performance and durability in mechanical applications.
Latest Patents
One of her latest patents is for a deep-groove ball bearing. This design includes an outer ring, an inner ring, a plurality of balls, and a seal member. The axial cross-sectional width is smaller than the radial cross-sectional height, and the thickness of the inner ring is greater than that of the outer ring. Additionally, the pitch diameter of the ball is larger than the median diameter between the inner diameter of the inner ring and the outer diameter of the outer ring. This configuration allows for reduced width and weight, secured load capacity, prevention of grease leakage, and an extended service lifespan. Another notable patent involves a lubricant composition and a rolling bearing that utilizes this composition. The lubricant contains a fatty acid metal salt, a metal dithiocarbamate, a phosphorous-type additive, and a basic additive, with a total acid value of 3.7 mgKOH/g or more. This innovation improves anti-fretting performance and reduces the decrease in fretting resistance, even when exposed to fluorine-type grease.
