[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0031] Reference Figure 1-7 A motor bearing protection structure includes a motor body 1, the motor body 1 includes a shell 101 and a rotating shaft 102, the shell 101 is provided with an auxiliary structure 2, the auxiliary structure 2 includes a lubricating component 3, the lubricating component 3 is provided with an auxiliary component 4, the lubricating component 3 includes a storage box 301, the storage box 301 is provided with a connecting component 302, the auxiliary component 4 includes a half gear 401, the side of the half gear 401 is provided with an auxiliary component 402, the half gear 401 is fixedly connected to the rotating shaft 102 and is not in the sealing cavity 1011, and the half gear 401 is staggered with the inclined plate 103.

[0032] A sealed cavity 1011 is provided in the housing 101, and the sealed cavity 1011 can be filled with lubricating oil, which can cool down the body while lubricating. Both ends of the rotating shaft 102 pass through the sealed cavity 1011 and extend a portion thereof. A plurality of inclined plates 103 are fixedly connected to the outer surface of the rotating shaft 102, and the plurality of inclined plates 103 are all located in the sealed cavity 1011. The plurality of inclined plates 103 are arranged at equal angles, and the inclined plates 103 can stir the lubricating oil when rotating, thereby making the temperature of the lubricating oil in the sealed cavity 1011 as even as possible.

[0033] A liquid inlet 3011 is provided on the top of the storage box 301. The liquid inlet 3011 is used for adding lubricating oil. A maximum scale is set in the storage box 301. The maximum scale does not exceed the second fixed tube 3022. The lubricating oil should not be added beyond the maximum scale, and the lubricating oil in the storage box 301 should not be filled up. A plug 3012 is provided in the liquid inlet 3011. The storage box 301 is located on one side of the outer shell 101 and corresponds to the sealed cavity 1011.

[0034] The connecting assembly 302 includes a No. 1 fixed tube 3021 and a No. 2 fixed tube 3022 which are fixedly connected to the storage box 301, and the other ends of the No. 1 fixed tube 3021 and the No. 2 fixed tube 3022 are fixedly connected to the outer shell 101. The No. 1 fixed tube 3021 and the No. 2 fixed tube 3022 are both provided with control valves, which are not shown in the figure. The two ends of the No. 1 fixed tube 3021 and the No. 2 fixed tube 3022 are respectively connected to the storage box 301 and the sealed cavity 1011. One end of the No. 1 fixed tube 3021 is located at the bottom of the storage box 301, and one end of the No. 2 fixed tube 3022 is located on one side of the storage box 301 and is higher than the highest point of the sealed cavity 1011.

[0035] The auxiliary component 402 includes a slider 4021 slidably connected to the storage box 301, both ends of the slider 4021 pass through one side of the storage box 301 and extend a portion thereof, one side of the slider 4021 is fixedly connected to two connecting plates 4022, one end of the connecting plate 4022 passes through the outer shell 101 and extends into the sealed cavity 1011, one side of the connecting plate 4022 is fixedly connected to a rack 4023, and the rack 4023 corresponds to the half gear 401, the two racks 4023 are symmetrically arranged, and the half gear 401 is located between the two racks 4023.

[0036] Before use, inject the lubricating liquid into the storage box 301 through the liquid inlet 3011 until it reaches the maximum scale. During this process, the lubricating liquid entering the storage box 301 will enter the sealed cavity 1011 through the No. 1 fixed tube 3021 and fill the sealed cavity 1011, thereby immersing the bearing in the lubricating liquid to achieve lubrication. Then, the plug 3012 is used to block the liquid inlet 3011, and then the control valves on the No. 1 fixed tube 3021 and the No. 2 fixed tube 3022 are adjusted. The lubricating liquid in the No. 1 fixed tube 3021 can only enter the storage box 301 from the sealed cavity 1011, while the opposite is true for the No. 2 fixed tube 3022.

[0037] When in use, the rotating shaft 102 will rotate with the inclined plate 103 and the half gear 401. As the rotating shaft 102 rotates, the bearing will generate a large amount of heat. At this time, the lubricating fluid can also cool the bearing. Under the principle of thermal expansion and contraction, the lubricating fluid in the sealed chamber 1011 will expand, thereby causing the pressure in the sealed chamber 1011 to increase. At this time, the lubricating fluid will flow to the storage box 301 through the No. 1 fixed tube 3021.

[0038] When the half gear 401 rotates, it will move the two racks 4023 back and forth, and when the racks 4023 move, they will move the connecting plate 4022, so that the slider 4021 slides in the storage box 301. When the slider 4021 moves to the farthest point, it will not block the No. 1 fixed tube 3021. When the slider 4021 moves outward, the volume in the storage box 301 will decrease, thereby increasing the pressure in the storage box 301. This will cause a pressure difference between the storage box 301 and the sealed cavity 1011. At this time, the lubricating fluid in the storage box 301 will pass through the No. 2 fixed tube 3022. The lubricating fluid in the sealed cavity 1011 often flows in the sealed cavity 1011 and increases the pressure in the sealed cavity 1011, and the lubricating fluid in the sealed cavity 1011 flows into the storage box 301 through the No. 1 fixed tube 3021, so that the lubricating fluid circulates in the storage box 301 and the sealed cavity 1011, thereby cooling the lubricating fluid in the sealed cavity 1011; when the slider 4021 moves inward, the volume in the storage box 301 decreases, thereby reducing the pressure in the storage box 301, and changing the pressure difference between the storage box 301 and the sealed cavity 1011 again, so that the lubricating fluid circulates.

[0039] At the same time, the rotation of the inclined plate 103 can stir the lubricating oil in the sealing chamber 1011 and make its temperature more uniform.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model.
