[Case Study] Introduction of Implementation Examples in the Automotive and Engine Fields (Clients: Toyota Motor Corporation, LiquidPiston, etc.)

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 are prone to challenges, such as vacuum, water, rust, high temperatures, high-speed rotation, and micro-vibration. Here, we introduce actual delivery cases. ■Delivery Achievements: Toyota Motor Corporation, LiquidPiston, and others We delivered a design report for ADB that meets the high-speed rotation conditions of 180,000 rpm with a shaft diameter of 33 mm, specifically for turbochargers that are exposed to particularly harsh environments among automotive parts. Additionally, we have confirmed the use of smaller diameter products (see photo).

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.
