DETAILED DESCRIPTION

[0024] The present application will be further described below with reference to the drawings.

[0025] Example 1, refer to Figures 1-2The present invention includes a shaft body 1, a shaft hole 2 that runs through the front and back at the center of the shaft body 1, and mounting holes 3 that are located away from the center of the shaft body 1 distributed around the outer circumference of the shaft hole 2. The mounting holes 3 are connected to the shaft hole 2.

[0026] Reference Figures 1-2 Multiple oil reservoirs 4 are circumferentially distributed near one end of the outer wall of the shaft 1. Each oil reservoir 4 contains an oil storage cavity 5. The oil storage cavity 5 contains a lubrication assembly 6 for lubricating the outer circumferential surface of the shaft 1. The lubrication assembly 6 includes multiple electrically operated telescopic columns 601 located at the bottom of the oil reservoir 4. Each of the electrically operated telescopic columns 601 has a pressure plate 602 placed horizontally inside the oil reservoir 4 on the side facing the outer circumferential surface of the shaft 1. The outer wall of the pressure plate 602 is in contact with the inner wall of the oil reservoir 4. A first spring 603, pressed against the pressure plate 602 and the bottom of the oil reservoir 4, is sleeved on the outer wall of the electrically operated telescopic columns 601. Corresponding arc-shaped openings 604 are provided near the outer wall of the shaft 1 and on the outer wall of the shaft 1. The arc-shaped openings 604 connect the oil storage cavity 5 to the outside. A corresponding [missing information - likely a specific component or element] is placed inside the arc-shaped opening 604. The oil reservoir 4 is equipped with a matching ball bearing 605 and a liquid sensor 606 for detecting lubricating oil located between the pressure plate 602 and the arc-shaped opening 604. The cover plate 7 has an oil inlet 12 on one side corresponding to the oil reservoir 4, which connects to the oil storage cavity 5. When the machine shaft is running, it is easy to cause jamming or wear on the outer wall of the machine shaft due to excessive friction. This utility model delivers lubricating oil to the oil reservoir 4 through the oil inlet 12 of the cover plate 7.
