Lubricating Patents (Class 384/13)
  • Patent number: 11020933
    Abstract: The present invention relates to techniques for lowering friction between moving surfaces of, for example, an internal combustion engine. Friction reduction is achieved by adding texture modifications to surfaces that come in contact with each other. Texture modifications that reduce friction in accordance with the present invention include dimples of varying geometries and depths ion the surfaces of components. The present invention also relates to the fabrication technique for applying the texture to the surfaces. In another embodiment, the patterned soft mask is applied onto a large surface (flat or curved including cylindrical rollers surfaces) to be followed by electrochemical etching to imprint the textures onto the component And, in another embodiment, a diamond-like-carbon (DLC) film may be applied to the turbine component to also reduce friction.

  • Patent number: 8998491
    Abstract: A linear actuator includes a guide mechanism and a retainer. On a guide block of the guide mechanism, a pair of ball-circulating grooves is formed on the lower surface that faces a cylinder body. Multiple balls are loaded in the ball-circulating grooves. Paired cover blocks are respectively mounted on the two ends of the guide block. The retainer has the form of paired ball clips, which are formed as arms to engage with the cover blocks when the clips are inserted in the ball-circulating grooves to hold the balls. Paired cover plates are respectively mounted on the end faces of the cover blocks, and arm-shaped cover clips are mounted so as to hold the cover plates. The cover plates, the cover blocks, and the guide block are thereby integrally linked.

  • Patent number: 8888367
    Abstract: Lubrication for rolling elements is carried out within the turnaround passages. For resupply of lubricant, the end seals and end caps have lubricating holes lying in alignment with each other to allow any lubricant injection needle piercing through there. A porous compact impregnated with lubricant fits in a concavity in the end cap. The concavity has an opening to communicate the concavity with the turnaround passage. The porous compact is composed of reservoirs, conjunctive parts, and applicator noses extending through openings to expose their tips into the turnaround passages. The lubricating hole in the end cap has a slit through which the porous compact is exposed to the lubricating hole to allow the lubricant flowing into the porous compact.
