Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel shafts, in particular to an abrasion-resistant and scratch-proof stainless steel shaft. Background Technique

[0002] The shaft body is a connecting and transmitting component for power input and output. One end is connected to a gear and a gearbox through a bearing as the power input end, and the other end is connected to an external output end through a bearing, and can also be used as the connection support of two components;

[0003] After retrieval, the Chinese patent with the publication number CN209918903U discloses a high-strength and low-cost milling machine spindle structure.

[0004] In the above technical solution: it includes a shaft rod, connection sleeves are installed on both sides of the shaft rod, magnet blocks are installed inside the connection sleeves, a threaded groove is provided on one side of the connection sleeve, threads are provided on the inner wall of the connection sleeve, positioning blocks are installed at both ends of the shaft rod, a tungsten carbide layer is provided inside the shaft rod, a chromium layer is provided inside the tungsten carbide layer, a stainless steel layer is provided inside the chromium layer, and reinforcing ribs are embedded inside the stainless steel layer. Compared with the prior art, the beneficial effect of the utility model is that the spindle structure is provided with a tungsten carbide layer, a chromium layer, reinforcing ribs and a stainless steel layer, which is designed as a multi-layer metal composite, with low production cost and high strength;

[0005] However, in the above solution, the shaft body is usually connected to components for connection support or power transmission. When this technology is used as the support for the rotational connection between two components, friction will occur between the components and the surface of the shaft body, and this connection will scratch the surface of the shaft body. Usually, lubricating oil is added to reduce friction, but it is difficult for the lubricating oil to enter deep into the connection between the components and the shaft body. When the shaft body transmits power, components with transmission characteristics such as gears will be installed. Lubricating oil also needs to be applied between the gears to prevent excessive gear friction. The exposed gears can be directly lubricated, but more gears are installed inside. Although oil injection nozzles are provided inside these gears, the rotation of the gears causes the oil injection nozzles to be blocked by other components, making it inconvenient to apply lubricating oil.
