Latest Patents
Among his latest patents are innovations such as the lubricant sealing structure and strain wave gearing. The lubricant sealing structure is designed to prevent lubricant leakage through a gap between a hollow input shaft and an end plate. This innovative design incorporates a labyrinth seal that effectively seals the gap. The labyrinth seal is constructed with multiple gap portions defined by an oil-repellent surface featuring fine grooves arranged in a specific pattern. This oil-repellent surface is also present on the outer peripheral surface of the labyrinth seal, enhancing its effectiveness. The combination of the oil-repellent effect, the sealing capability of the labyrinth seal, and the oil-repellent surface work together to reliably prevent lubricant oil from leaking outside the device.
Another notable patent involves a strain wave gearing that includes a lubricant sealing structure. This design also aims to prevent lubricant leakage through a gap portion between a hollow input shaft and an end plate. The sealing structure consists of an oil-repellent surface facing the gap, an oil seal that effectively seals the gap, and an oil film
