Latest Patents

One of Yuichi Iguchi's latest patents is an oil feeding arrangement for shaft seal and bearings. This invention involves a bearing located in a bore formed in a casing, which rotatably supports a shaft extending inside the casing. A shaft seal is positioned between the shaft and the bearing bore, spaced from the bearing in a longitudinal direction of the shaft. An oil chamber is defined by the shaft seal and the bearing, with an oil feed hole formed in the casing to directly feed oil into the oil chamber from an oil source. The oil is then directed to the bearing from the oil chamber. A partition plate is placed in the oil chamber to create a gap between the shaft and itself, allowing part of the oil to flow to the bearing while the remainder is dammed by the partition plate to form an oil pool in which the shaft seal is always immersed.

Another significant patent is for a bearing support for a Lysholm compressor. In this invention, the Lysholm compressor features intermeshing male and female rotors that rotate within a casing to compress an axially flowing gas. The discharge-side shafts of the rotors are supported by discharge-side bearings, which fix the shafts in the thrust direction, while the suction-side shafts are borne by suction-side bearings, allowing movement in the thrust direction. The clearances of the rotors to the casing are properly set or selected to ensure optimal performance.
