Latest Patents

One of Okamoto's latest patents is a bearing with an oil film thickness measuring device. This invention features sensor portions at the distal ends of four common optical fibers, which are connected to sensor mounting portions located at four positions along the axial direction of the bearing body. A lubricating oil containing a fluorescent agent is supplied to the sliding surface of the bearing body. A laser beam generated from a laser beam generator is branched into four beams, which are applied to the oil film on the sliding surface through each of the sensor portions. The fluorescence generated by the fluorescent agent in the oil film is introduced into a photomultiplier tube via a return-route optical fiber, allowing for the detection of the oil film thickness. This method enables the measurement of oil film thickness at four distinct positions.

Another notable invention is a cylindrical sliding bearing. In this design, the radial rigidity of the inner circumferential surface of the sliding layer varies in the circumferential direction. This variation allows the inner circumferential surface to include areas of relatively high and low radial rigidity, enhancing the bearing's performance under radial compression forces.
