Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a cooling structure for a bearing end cover. Background Art

[0002] As an important part in mechanical design, the bearing end cover not only plays a role in protecting the bearing, dust-proof sealing and axial positioning. Among them, the bearing end cover affects the heat dissipation effect of the entire mechanical system through its structural design. The existing cooling method of the bearing end cover mainly relies on the heat conduction ability of the end cover itself to dissipate heat, and transfers the heat to the external environment through the material itself. However, the effect of this cooling method is limited by various factors. For example, the single heat conduction method has a low heat dissipation efficiency in the face of high-load or high-temperature environments. Since most bearing end covers are made of materials such as stainless steel, the heat conduction performance of these materials is limited and they cannot quickly and effectively export the heat, resulting in heat accumulation. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a cooling structure for a bearing end cover to solve the problem of poor heat dissipation effect of the existing bearing end cover.

[0004] To achieve the above purpose, the utility model provides a cooling structure for a bearing end cover, including an annular body;

[0005] An arc-shaped groove is coaxially opened at a position close to the inner ring inside the annular body, and a water inlet hole and a water outlet hole are respectively opened on the outer ring wall of the annular body. The water inlet hole and the water outlet hole are respectively communicated with the arc-shaped groove and are respectively located at the head end and the tail end of the arc-shaped groove.

[0006] A preferred solution is that both the water inlet hole and the water outlet hole are arranged radially along the annular body.

[0007] A preferred solution is that a plurality of first through holes are opened on the side wall of the annular body close to the outer circle circumference;

[0008] A plurality of second through holes are opened on the side wall of the annular body close to the inner circle circumference.

[0009] A preferred solution is that the annular body is made of stainless steel material.

[0010] A preferred solution is that it further includes two connecting pipes. The outer wall circumference of one end of the connecting pipe is provided with a first thread, and a flexible pipe is coaxially communicated with the other end;

[0011] The water inlet hole and the water outlet hole are provided with a second thread close to the outer circle;

[0012] The first thread is screwed with the second thread.

[0013] A preferred solution is that it further includes a water supply structure, and the water supply structure includes a water tank, a water pump, a water inlet pipe and a return pipe;

[0014] A water inlet pipe is provided with a water pump along the way. One end of the water inlet pipe is communicated with a water tank, and the other end is sleeved on a flexible pipe located on the water inlet hole.

[0015] One end of the return pipe is communicated with the water tank, and the other end is sleeved on a flexible pipe located on the water outlet hole.

[0016] The beneficial effects of the above solution are as follows:

[0017] The water inlet hole and the water outlet hole are connected to the water supply structure in the prior art. The flowing cooling water sequentially passes through the water inlet hole, the arc-shaped groove, and the water outlet hole. Through the arc-shaped groove coaxially arranged at a position close to the inner ring in the annular body, the bearing end cover forms an internal circulation cooling. The cooling water circulating inside conducts heat out, thereby reducing the temperature of the bearing and the surrounding structure. This cooling method not only improves the cooling efficiency, but also prolongs the service life of the structure and enhances the stability of the entire system. In addition, the internal circulation cooling quickly absorbs and discharges heat through the internal cooling medium, effectively preventing heat from accumulating inside the structure.

[0027] As Figures 1 - 4 shown, this embodiment provides a cooling structure for a bearing end cover, including an annular body 1. The annular body 1 is made of stainless steel. A plurality of first through holes 5 are opened in the side wall of the annular body 1 near the outer circumference of the outer ring. A plurality of second through holes 6 are opened in the side wall of the annular body 1 near the inner circumference of the inner ring.

[0028] An arc-shaped groove 2 is coaxially opened near the inner ring position inside the annular body 1. An inlet hole 3 and an outlet hole 4 are respectively opened on the outer ring wall of the annular body 1. The inlet hole 3 and the outlet hole 4 are both arranged along the radial direction of the annular body 1. The inlet hole 3 and the outlet hole 4 are respectively communicated with the arc-shaped groove 2, and the inlet hole 3 and the outlet hole 4 are respectively located at the head end and the tail end of the arc-shaped groove 2.

[0029] The inlet hole 3 and the outlet hole 4 are communicated with a water supply structure 10 in the prior art. The flowing cooling water sequentially passes through the inlet hole 3, the arc-shaped groove 2, and the outlet hole 4. By arranging the arc-shaped groove 2 coaxially opened near the inner ring position inside the annular body 1, an internal circulation cooling is formed for the bearing end cover. The cooling water circulating inside conducts heat out, thereby reducing the temperature of the bearing and the surrounding structures. This cooling method not only improves the cooling efficiency, but also extends the service life of the structure and enhances the stability of the entire system. In addition, the internal circulation cooling quickly absorbs and discharges heat through the internal cooling medium, effectively preventing heat from accumulating inside the structure.

The outer circumference of one end of the connecting pipe 7 is provided with a first thread 8, and a flexible pipe 9 is coaxially communicated with the other end of the connecting pipe 7. Second threads are opened near the outer ring of the inlet hole 3 and the outlet hole 4. The first thread 8 is screwed with the second thread. This facilitates the quick disassembly and assembly of the two connecting pipes 7 with the inlet hole 3 and the outlet hole 4.

[0031] As Figure 4As shown, the cooling structure of the bearing end cover further includes a water supply structure 10, and the water supply structure 10 includes a water tank 11, a water pump 12, a water inlet pipe 13 and a return pipe 14. The water inlet pipe 13 is provided with the water pump 12 along the way. One end of the water inlet pipe 13 is communicated with the water tank 11, and the other end of the water inlet pipe 13 is sleeved on the flexible pipe 9 located on the water inlet hole 3. One end of the return pipe 14 is communicated with the water tank 11, and the other end of the return pipe 14 is sleeved on the flexible pipe 9 located on the water outlet hole 4.

[0032] Start the water pump 12 to work. The cooling water sequentially passes through the water tank 11, the water inlet pipe 13, the water pump 12, the connecting pipe 7, the water inlet hole 3, the arc-shaped groove 2, and the water outlet hole 4, another connecting pipe 7, and the return pipe 14 and returns to the water tank 11. Through such a structural design, the continuously circulating cooling water inside continuously conducts heat out. In addition, the design of the flexible pipe 9 facilitates sleeving on the water inlet pipe 13 or the return pipe 14.

[0033] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
