Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a bearing ring which is convenient for lubrication. Background Art

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the rotating body of the machine, reduce the friction coefficient during its movement, and ensure its rotation accuracy; a bearing ring is an annular part of a radial rolling bearing with one or more raceways. The bearing ring is divided into an outer ring and an inner ring, and the two together with the rollers form a rolling bearing.

[0003] When a bearing is in use, a thin oil film needs to be formed on its rolling surface and sliding surface to prevent excessive wear between the balls and the bearing ring. However, a dust cover is usually installed between the outer ring and the inner ring of the existing bearing for dust prevention, resulting in the need to remove the dust cover when adding lubricating oil, making the addition of lubricating oil less convenient. For this reason, we propose a bearing ring which is convenient for lubrication to solve the above-mentioned problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a bearing ring which is convenient for lubrication to solve the problems mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a bearing ring which is convenient for lubrication, comprising:

[0006] A bearing ring body, a raceway is opened on the inner wall of the bearing ring body, a plurality of annularly and equidistantly distributed oil storage grooves are opened on one side wall of the bearing ring body, a plurality of oil outlet holes are opened on the raceway, and the plurality of oil outlet holes are respectively communicated with the plurality of oil storage grooves. A sponge adsorbed with lubricating oil is placed in each of the plurality of oil storage grooves. A sealing ring is arranged on one side wall of the bearing ring body where the oil storage groove is opened. A plurality of sliding rods are slidably connected to the sealing ring. One ends of the plurality of sliding rods are fixedly welded with pressing plates, and the plurality of pressing plates are respectively arranged in the plurality of oil storage grooves. The outer ends of the plurality of sliding rods are fixedly welded with a pressing ring. A part of the sliding rods is sleeved with a tension spring, and two ends of the tension spring are respectively fixedly connected with the sealing ring and the pressing ring.

[0007] Preferably, a plurality of fastening bolts are arranged on the sealing ring, and a plurality of screw holes are opened on one side wall of the bearing ring body where the oil storage groove is opened. The plurality of fastening bolts are respectively threadedly connected in the plurality of screw holes.

[0008] Preferably, sealing gaskets are fixedly bonded to the edges of the plurality of oil storage grooves.

[0009] Preferably, a sealing ring is fixedly installed on the pressing plate.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] When in use, when it is necessary to lubricate the balls of the bearing, the pressing ring can be pressed towards the bearing race, so that the pressing ring drives a plurality of sliding rods to slide on the sealing ring, thereby driving a plurality of pressing plates to move inwards in the oil storage groove to squeeze the sponge adsorbed with lubricating oil. After being squeezed, the adsorbed lubricating oil flows out of the sponge and flows into the raceway of the balls through the oil outlet holes, realizing the lubrication effect of the balls in the raceway. The operation is simple and convenient, and there is no need to disassemble and assemble the dust cover of the bearing back and forth, greatly improving the convenience of ball lubrication.
