Description

Technical Field

[0001] The utility model relates to the field of bearings, in particular to a wear-resistant bearing ring. Background Art

[0002] Sliding bearings are a common type of bearings, also known as lubricating pairs. This type of bearing is mainly composed of inner and outer sleeves and grease. Compared with ordinary bearings, it only forms a lubricating film through lubricants to reduce the contact friction between the bearing and the shaft. Therefore, its bearing ring is subject to greater friction than that of a bearing with rollers. Especially during its operation, the inner ring often deflects due to the leakage of lubricating oil, which wears the outer ring. Therefore, a bearing ring with good lubrication effect and more wear resistance is required. Summary of the invention

[0003] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures specifically pointed out in the description and the drawings of the description.

[0004] The utility model aims to overcome the above-mentioned shortcomings and provide a wear-resistant bearing ring which has the advantages of good self-lubricating effect, being able to support automatic oil replenishment during operation and being more wear-resistant.

[0005] The utility model provides a wear-resistant bearing ring, wherein a bearing inner ring is sleeved inside the bearing ring, comprising a bearing outer ring, an oil felt ring and a partition ring, the inner circle of the bearing outer ring is provided with a baffle, the baffle is bent upward along the axial direction and forms an annular limiting cavity with the side wall of the bearing outer ring, the oil felt ring is arranged in the limiting cavity, the partition ring covers the top of the oil felt ring, the outer circle of the partition ring is provided with a plurality of oil grooves, and the bearing inner ring is arranged above the partition ring.

[0006] In some embodiments, at least one oil inlet channel is provided through the side wall of the outer ring of the bearing, the inner ring of the outer ring of the bearing is provided with a first guide groove, and the outer ring of the inner ring of the bearing is provided with a second guide groove. When replenishing lubricating oil, the oil inlet channel connects the first guide groove and an external oil inlet pipe.

[0007] In some embodiments, an extension portion extends outward from the top of the baffle, and the extension portion is in contact with and connected to the inner circle of the inner ring of the bearing.

[0008] In some embodiments, the bearing ring further includes a sealing ring, which is disposed on a side of the bearing outer ring away from the baffle and connected to the bearing inner ring.

[0009] In some embodiments, an annular oil storage chamber is provided in the sealing ring, and a plurality of balls are provided at the abutment between the sealing ring and the inner ring of the bearing, and the oil storage chamber provides lubricating oil for the balls.

[0010] By adopting the above technical solution, the beneficial effects of the utility model are:

[0011] 1. The utility model arranges a felt ring and a partition ring on the outer ring of the bearing. When the bearing is filled with lubricating oil, part of the lubricating oil passes through the oil groove and is stored in the gap in the partition ring and absorbed by the felt ring. When the inner ring of the bearing is unbalanced due to leakage of the lubricating oil, the partition ring is squeezed by the inner ring of the bearing, causing the lubricating oil absorbed by the felt ring to be discharged from the oil groove, and the space between the outer ring and the inner ring of the bearing is supplemented with lubricating oil, thereby realizing automatic oil replenishment during movement and improving the wear resistance of the outer ring.

[0012] 2. The utility model realizes the oil inflow of the bearing inner ring and the bearing outer ring by setting the guide groove, reduces the contact between the two, and further reduces the friction between the two; limits the movement of the bearing inner ring by setting the extension part to prevent it from shifting and increasing the friction between the two; facilitates the installation of the bearing by setting the sealing ring, and at the same time sets the ball between the sealing ring and the bearing inner ring to reduce the friction between the two.

[0013] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.

[0014] Undoubtedly, these and other objects of the present invention will become more apparent after the following detailed description of the preferred embodiments described with reference to various figures and drawings.
