  • Patent number: 12188521
    Abstract: A rolling bearing fully-filled with plastic oil comprises an outer ring, an inner ring, a rolling element between the outer ring raceway and the inner ring raceway, a cage, and a plastic oil to provide lubrication for the bearing. The plastic oil includes a porous lubricating material containing oil. The plastic oil in a fluid state is combined with the rolling element and the cage to present a plastic state and forms an assembly of the rolling element, the cage and the plastic oil after the plastic oil is heated and cured with the bearing. When the bearing is running, the assembly revolves, the rolling element rotates in a window or pocket of the cage, and the lubricating oil contained in micropores of the plastic oil spills out of the micropores to lubricate the bearing.

  • Publication number: 20240337034
    Abstract: Systems and methods are provided for operating an electrolyzer. The systems and methods perform operations comprising extracting, by monitoring circuitry coupled to a plurality of electrolytic cells of an electrolyzer, a set of features comprising at least one of a goodness-of-fit measurement or direct current (DC) measurement of the plurality of electrolytic cells; tracking changes to the set of features over a time period; and generating, based on the changes to the set of features, a model representing operating conditions of the electrolytic cells on an individual electrolytic cell basis.

  • Publication number: 20240093733
    Abstract: Disclosed are a rolling bearing with fully-filled plastic oil and a manufacturing method therefor. A clearance between the existing cage and an outer ring raceway or outer ring flange or/and between the cage and an inner ring raceway or/and inner ring flange is so small that a plastic oil fluid cannot be filled into a free space inside the bearing fully, which not only limits the advantages of plastic oil-lubricated bearings, but also has other negative effects. In the invention, without affecting the performance of the bearing, unilateral radial clearances between the cage and an outer ring and between the cage and an inner ring are increased to over 0.
