Description

Technical Field

[0001] This utility model relates to the field of bearing plate technology, specifically to an oil-free lubricated bearing plate. Background Technology

[0002] Oil-free lubricated bearings are sliding bearings that can operate stably for a long time without external lubricating oil. They achieve friction reduction and wear resistance through the material itself or embedded solid lubricants. The bearing plate of oil-free lubricated bearings is a bimetallic plate with low carbon steel as the base material. A copper and steel alloy layer is formed on the outer surface of the low carbon steel through a high-temperature sintering process.

[0003] Existing oil-free lubricated bearing plates, after being sintered with low-carbon steel and copper / steel alloys, achieve a dense bond between the two metals through repeated rolling. However, it has been found that the different metals have different thermal deformation coefficients, and cracks easily appear between the base material and the sintered metal when there are frequent temperature changes. Although repeated rolling achieves a dense bond between the two metals, the interfacial bonding force between the different metals is insufficient. Therefore, we propose an oil-free lubricated bearing plate to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide an oil-free lubricated bearing plate to solve the problems currently found in the market as described in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil-free lubricated bearing plate, comprising a bimetallic plate, wherein the bimetallic plate is composed of a base metal plate and a sintered metal plate, and graphite insertion holes are equidistantly arranged on the bimetallic plate, wherein...

[0006] The substrate metal plate has a first slot equidistantly formed on the side near the sintered metal plate. A first strip is fixedly connected to the side of the sintered metal plate corresponding to the first slot. A second slot is formed on the side of the sintered metal plate near the first strip. A second strip is fixedly connected to the side of the substrate metal plate corresponding to the second slot.

[0007] Preferably, the substrate metal plate is made of low-carbon steel.

[0008] Preferably, the sintered metal plate is made of a steel-copper alloy.

[0009] Preferably, both the first card slot and the second card slot are T-shaped slots, and the internal dimensions of the first card slot and the second card slot match the external dimensions of the first card strip and the second card strip.

[0010] Preferably, the first card strip and the sintered metal plate are integrally fixedly connected.

[0011] Preferably, the second card strip is integrally fixedly connected to the base metal plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In the production of bimetallic plates, the substrate metal plate is pre-processed to form a first groove and a second strip. Alloy powder is then spread evenly on the substrate metal plate, and the substrate metal plate and the sintered metal plate are bonded together by sintering. The pre-processed first groove and second strip ensure a tight bond between the substrate metal plate and the sintered metal plate, greatly enhancing the bonding strength between them and preventing cracks from appearing.

[0014] In this invention, steel-copper alloy powder is spread evenly on a base metal plate 2, and then sintered to form a sintered metal plate 3. After the sintered metal plate 3 is formed, a first retaining strip 6 and a second retaining groove 7 are automatically formed, so that the first retaining groove 5, the first retaining strip 6, the second retaining groove 7 and the second retaining strip 8 are tightly connected. After rolling, cracks are avoided between the base metal plate 2 and the sintered metal plate 3 under extreme working conditions, thereby improving the safety of the oil-free lubricated bearing.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3 This utility model provides a technical solution: an oil-free lubricated bearing plate, comprising a bimetallic plate 1, which is composed of a base metal plate 2 and a sintered metal plate 3. Graphite insertion holes 4 are equidistantly arranged on the bimetallic plate 1.

[0021] The base metal plate 2 has a first slot 5 equidistantly opened on the side close to the sintered metal plate 3. The sintered metal plate 3 is fixedly connected to the side corresponding to the first slot 5 with a first strip 6. The side of the sintered metal plate 3 close to the first strip 6 has a second slot 7. The base metal plate 2 is fixedly connected to the side corresponding to the second slot 7 with a second strip 8.

[0022] During the production of bimetallic plate 1, the base metal plate 2 is pre-processed, and a first slot 5 and a second slot strip 8 are processed on the base metal plate 2. Alloy powder is then spread evenly on the base metal plate 2, and the base metal plate 2 and the sintered metal plate 3 are bonded together by sintering. Through the pre-processed first slot 5 and second slot strip 8, the base metal plate 2 and the sintered metal plate 3 are tightly bonded together by the first slot 5, the first slot strip 6, the second slot 7 and the second slot strip 8, which greatly enhances the bonding strength between the base metal plate 2 and the sintered metal plate 3 and avoids cracks between the base metal plate 2 and the sintered metal plate 3.

[0023] Please see Figures 1 to 3 The base metal plate 2 is made of low-carbon steel, and the sintered metal plate 3 is made of steel-copper alloy.

[0024] Please see Figures 1 to 3 Both the first slot 5 and the second slot 7 are T-shaped slots, and the internal dimensions of the first slot 5 and the second slot 7 match the external dimensions of the first clip 6 and the second clip 8. The first clip 6 is integrally fixedly connected to the sintered metal plate 3, and the second clip 8 is integrally fixedly connected to the base metal plate 2. After steel-copper alloy powder is laid flat on the base metal plate 2, the sintered metal plate 3 is formed by sintering. After the sintered metal plate 3 is sintered, the first clip 6 and the second slot 7 are automatically formed, so that the first slot 5, the first clip 6, the second slot 7 and the second clip 8 are tightly connected. After rolling, cracks are avoided between the base metal plate 2 and the sintered metal plate 3 under extreme working conditions, thereby improving the safety of the oilless lubricated bearing.

[0025] Working principle: In the production of this oil-free lubricated bearing plate, the base metal plate 2 is pre-processed during the production of the bimetallic plate 1. A first groove 5 and a second strip 8 are machined on the base metal plate 2. Alloy powder is then spread evenly on the base metal plate 2, and the base metal plate 2 and the sintered metal plate 3 are bonded together through sintering. The pre-processed first groove 5 and second strip 8 ensure a tight bond between the base metal plate 2 and the sintered metal plate 3, greatly enhancing the strength of the base metal plate 2. The bonding strength between the base metal plate 2 and the sintered metal plate 3 is improved to prevent cracks from appearing between the base metal plate 2 and the sintered metal plate 3. After steel-copper alloy powder is spread on the base metal plate 2, the sintered metal plate 3 is formed by sintering. After the sintered metal plate 3 is formed, the first locking strip 6 and the second locking groove 7 are automatically formed, so that the first locking groove 5, the first locking strip 6, the second locking groove 7 and the second locking strip 8 are tightly bonded. After rolling, cracks are prevented from appearing between the base metal plate 2 and the sintered metal plate 3 under extreme working conditions, thereby improving the safety of the oilless lubricated bearing.
