Description

Technical Field

[0001] The invention belongs to the technical field of power pipeline supports, and in particular relates to a self-lubricating, low-friction silicon carbide power pipeline support. Background Art

[0002] In some high and low temperature environments, the physical properties of metal expansion and contraction often damage the equipment connected to it, resulting in thermal stress. There are strict requirements for the force at the connection between pipelines and equipment, especially for dynamic equipment, such as large units and industrial pumps. Once the external force exceeds the required value, the related equipment will be damaged, seriously affecting normal production. Therefore, high requirements are placed on the pipe support at the connection of dynamic equipment to reduce the force and ensure the safety of the equipment.

[0003] For example, the application number is: CN202121939451.3, and the name is: A Chinese utility model patent for a low-friction, large-displacement silicon carbide single crystal power system pipe bracket, which discloses that a bearing support is installed at the lower end of the bracket body, a bearing is installed inside the bearing support, and a roller is installed on the inner ring of the bearing; the utility model converts plane friction into rolling friction, thereby converting the sliding friction between the original bracket and the supporting beam into rolling friction, and the rolling friction force is much less than the original sliding friction force; it is only one-sixtieth of the original sliding friction force.

[0004] However, due to the gap between the rotating shaft and the outer ring of the bearing, the lubricating oil will overflow from the gap between the rotating shaft and the outer ring when the bearing rotates, causing the lubricating oil to gradually decrease, increasing the friction of the bearing, and thus reducing the service life of the bearing.
