[Case Study] Introduction of Implementation Cases in the Energy Sector (Clients: Railway Technical Research Institute, Wind Power Related Companies)

バリューイノベーションジャパン

<Introduction of Case Studies> ADB has been evaluated and adopted in environments where traditional bearings tend to face challenges, such as vacuum, water, rust, high temperatures, high-speed rotation, and micro-vibrations. Here, we introduce actual delivery cases. ■ Delivery Achievements: Railway Technical Research Institute, Wind Power Related Companies Due to the unavailability of the initially planned product for use as a touchdown bearing during magnetic bearing failure, ADB was urgently adopted. Through evaluation in actual machines, the stable support performance of ADB was confirmed, and there have been voices suggesting that "for radial support, ADB may be more suitable than magnetic bearings." Currently, it is being proposed as "flywheel energy storage."

Bearing 'ADB' that reduces friction by up to 1/14.
A huge response worldwide! Non-contact between balls without a holder = fundamentally solving the challenges of friction, damage, and lubrication management.

<Structure and Mechanism of ADB> The mechanism of ADB is very simple. There are small "indentations" where the outer ring's balls make contact. In a standard bearing, the balls roll directly beneath the shaft, but in ADB, the indentations on the outer ring cause the balls to roll slightly off to the side from directly underneath. As a result, even though the balls make a complete rotation, the distance they travel is shorter. This causes the balls to slightly decelerate when passing through the indentations and to accelerate again after passing through. Consequently, behind the accelerated balls, the following balls are still decelerating, creating small gaps between the balls. ADB utilizes this principle to naturally separate the balls without the use of retainers.
