Abstract

The present invention relates to the technical field of accessories for bearings, and discloses a bearing auxiliary lubrication assembly and a bearing lubrication structure. Among them, the bearing auxiliary lubrication assembly includes an oil injection circular arc section and an oil return circular arc section for being arranged on both axial sides of the bearing. A plurality of oil injection holes are provided on the oil injection circular arc section, and the outlet of each oil injection hole faces the circular ring area where the gap between the outer ring and the inner ring of the bearing is located. An oil guiding groove that is radially outwardly open and runs along the circumferential direction of the oil injection circular arc section is provided on the oil injection circular arc section, and the inlet of each oil injection hole is communicated with the oil guiding groove. By using the bearing auxiliary lubrication assembly of the present invention, the lubricating oil can be directly sprayed onto the rollers of the bearing through the way of guiding flow for lubrication, and part of the lubricating oil can return to the bearing through the oil return circular arc section to realize the re-lubrication of the bearing, so that the utilization rate and lubrication efficiency of the lubricating oil can be greatly improved.
