Description

Technical Field

[0001] This invention relates to the field of sliding bearing technology, specifically to sliding bearings for high-speed punch presses and their manufacturing process. Background Technology

[0002] Sliding bearings are spherical sliding bearings, with an inner spherical surface and an outer spherical surface as their sliding contact surfaces. They can rotate and oscillate at any angle during operation. They are manufactured using various special processes such as surface phosphating, slotting, extrusion, padding, and spraying. Sliding bearings are characterized by high load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning properties, and good lubrication.

[0003] The prior art discloses a bearing inner ring and its manufacturing process, as well as a self-lubricating spherical plain bearing, with publication number CN109139705A, belonging to the field of spherical plain bearing technology. The bearing inner ring includes a bearing inner ring substrate and a coating layer. The surface of the bearing inner ring substrate has a nitrided layer, and the coating layer is disposed on the surface of the nitrided layer. The nitrided layer on the surface of the bearing inner ring substrate effectively improves the surface hardness of the bearing inner ring substrate surface. The coating layer on the surface of the nitrided layer further improves the surface hardness and wear resistance of the bearing inner ring surface, reduces the friction coefficient of the bearing inner ring surface, and improves the anti-scraping ability of the bearing inner ring surface against the liner. The manufacturing process of the bearing inner ring includes preparing a nitrided layer on the surface of the bearing inner ring substrate using vacuum plasma nitriding, and then preparing a coating layer on the surface of the nitrided layer using physical vapor deposition. In the self-lubricating bearing, the bearing inner ring and the self-lubricating liner form a friction pair, reducing the wear rate of the liner and improving the service life of the spherical plain bearing.

[0004] The aforementioned sliding bearings utilize the inner ring of the bearing and the self-lubricating liner to form a friction pair during use, reducing the wear rate of the liner. However, the aforementioned sliding bearings do not have a self-lubricating component, which leads to excessive internal wear, affecting service life and resulting in poor practicality. Therefore, it is necessary to design a practical sliding bearing for high-speed punch presses and its manufacturing process. Summary of the Invention
