Title: Rolling bearing
Inventor: DAN TAKESHI
IPC: F16C33/58
Filed: 2019-04-16
Abstract: To provide a rolling bearing to be used under high speed rotation, for improving the performance of supplying lubricating oil to the internal of the bearing without requiring a scoop component and an oil groove.SOLUTION: An inner ring 10 of the rolling bearing has a trapping recessed part 16 opened to the end face to be able to trap lubricating oil injected from an oil supply nozzle, and an oil hole 18 leading from the trapping recessed part 16 to an inner ring outer diameter surface. The inner ring itself functions to trap the lubricating oil and supply it to the internal of the bearing, so there is no need for the scoop component conventionally needed to reduce the number of components. No need to provide the oil groove in the inner diameter surface of the inner ring prevents the creepage of the inner ring without reducing the contact area between a rotary shaft and the inner ring, resulting in no need to set an excessive interference. No need for the scoop component and the oil groove also results in no need for a complicated flow path design for the lubricating oil.SELECTED DRAWING: Figure 1
