An oil injection lubrication component for a bearing

Abstract

The present invention relates to the technical field of accessories for bearings, and discloses an oil injection lubrication assembly for bearings, which includes an oil injection ring and an oil return ring arranged on both axial sides of the bearing. The oil injection ring is provided with a plurality of oil injection holes, 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. The oil injection ring is provided with an oil guiding groove that extends along the circumferential direction of the oil injection ring and opens radially outward, and the inlet of each oil injection hole is communicated with the oil guiding groove. By setting the oil injection ring in the present invention, the lubricating oil no longer simply lubricates the bearing by relying on the natural flow mode, but directly jets onto the rollers of the bearing through the way of guiding and spraying, which can improve the utilization rate of the lubricating oil and the uniformity of lubrication, and through the oil return ring, part of the lubricating oil returns to the bearing again to realize the re-lubrication of the bearing, so that the utilization rate of the lubricating oil and the lubrication efficiency can be greatly improved, and the purpose of fully lubricating the bearing can be achieved.
