Patent JP-H074429-A (JP)
Title: Rolling bearing
Inventor: IJUIN SEIJI
IPC: F16C19/52
Filed: 1993-06-18
Abstract: PURPOSE:To prevent a bearing from being worn by providing a plurality of recessed grooves for a guide surface in the circumferential direction, tilting each recessed groove to the axial direction, and thereby making the aforesaid tilt direction a direction by which fluid within a rolling element set section is taken in the recessed groove by means of rotation. CONSTITUTION:Worn powder falls off when it passes through each recessed groove 9 even if worn powder bites in the surface of a guided surface 7a plated with silver. Meanwhile, there exists a flow in each recessed groove 9, which discharges lubricant and air within a cage 6 to the outside of the cage 6 by a pumping action followed by the rotation of an inner ring. By this constitution, worn powder having fallen off at the section of each recessed groove 9 is discharged out of the cage 6 by the flow, so that wear due to worn powder can thereby be prevented. Lubricant coming in the inside of each recessed groove 9 comes in a minute gap between a guide surface 8a and the guided surface 7a by a wedge action followed by the rotation of the inner ring, so that a firm lubricating film is thereby formed by a wedge film effect. Because of the aforesaid constitution, the lubricating film is hardly damaged even if the cage 6 is swung freely.
