AI Technical Summary
When existing roller shafts are used, it is difficult for lubricating oil to enter the bearing evenly, resulting in insufficient lubricity in some areas.
A roller shaft is designed for easy lubrication, including a spindle, bearing body, arcuate baffle and oil outlet hole. Lubricating oil enters between the outer ring and inner ring of the bearing through the oil outlet hole of the arc baffle, achieving automatic lubrication.
This design allows lubricating oil to enter the bearing evenly, avoiding the inconvenience of manual manual coating, ensuring uniform lubrication of the bearing and extending service life.

[0013] (III) Beneficial effects
[0014] Compared with the prior art, the utility model provides a roller shaft that is easy to lubricate and has the following features:
[0015] Beneficial effects:
[0016] The roller shaft which is easy to lubricate drips lubricating oil into the arc-shaped baffle plate. At this time, the lubricating oil will flow in the arc-shaped baffle plate and drop between the outer ring of the bearing and the inner ring of the bearing at multiple oil outlet holes. This process does not require manual application of the outer ring of the bearing and the inner ring of the bearing, and the lubricating oil can be evenly applied to the outer ring of the bearing and the inner ring of the bearing in the arc-shaped baffle plate, so that the bearing body can be easily lubricated.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-4 The utility model is a roller shaft that is easy to lubricate, comprising a main shaft 3 and a bearing body, wherein the bearing body comprises a bearing outer ring 1 and a bearing inner ring 2, a plurality of balls are arranged between the bearing outer ring 1 and the bearing inner ring 2, the main shaft 3 passes through the bearing inner ring 2, and there is an interference fit between the main shaft 3 and the bearing inner ring 2, an arc-shaped baffle 4 is fixedly arranged on one side of the bearing inner ring 2, a plurality of oil outlet holes 6 are arranged at the bottom of the arc-shaped baffle 4, and a circular baffle 5 is fixedly arranged on the top of the arc-shaped baffle 4;
[0024] When the present structure is in use, the main shaft 3 is mostly in a vertical state. Through the multiple balls provided, the bearing inner ring 2 can make the bearing outer ring 1 rotate normally under different conditions, and the lubricating oil can be dripped into the arc baffle 4. At this time, the lubricating oil will flow in the arc baffle 4, and the lubricating oil will fall between the bearing outer ring 1 and the bearing inner ring 2 at the multiple oil outlet holes 6. This process does not require manual application of the bearing outer ring 1 and the bearing inner ring 2, and the lubricating oil can be evenly introduced into the arc baffle 4 between the bearing outer ring 1 and the bearing inner ring 2, so that the bearing body can be easily lubricated.
[0025] Furthermore, the arc baffle 4 and the circular baffle 5 are an integrated structure, and both the arc baffle 4 and the circular baffle 5 are made of metal, and both the arc baffle 4 and the circular baffle 5 can be made of aluminum alloy. Aluminum alloy has the advantages of high strength and good corrosion resistance, which can make the arc baffle 4 and the circular baffle 5 not easily damaged.
[0026] In this structure, the sizes of the plurality of oil outlet holes 6 are the same.
[0027] In this structure, a frame 7 is provided inside the arc baffle 4, and the frame 7 is fixed inside the arc baffle 4 through a support plate 8. By providing the frame 7, when the main shaft 3 is in a horizontal state, the lubricating oil can be conveniently added to the inside of the arc baffle 4 through the frame 7. As the bearing outer ring 1 rotates, the lubricating oil can still drip evenly between the bearing outer ring 1 and the bearing inner ring 2.
[0028] Furthermore, the frame 7 and the support plate 8 may be an integrated structure.
