DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0027] Embodiment 1

[0028] As shown Figures 1 to 2 in the figure, this embodiment proposes a bearing sealing structure, including a sealing structure 2. The sealing structure 2 includes a protective shell 201. A fixing block 202 is fixedly connected to the side surface of the protective shell 201. A rotating rod 203 is fixedly connected to the side surface of the fixing block 202. One end of the rotating rod 203 away from the fixing block 202 is rotatably connected to a mounting block 204. One end of the mounting block 204 away from the rotating rod 203 is rotatably connected to a cover plate 205. A positioning block 206 is fixedly connected to the side surface of the cover plate 205. A rotating rod 207 is rotatably connected to the side surface of the positioning block 206. A rotating plate 208 is fixedly connected to the circumferential surface of the rotating rod 207. A rotating shaft 210 is rotatably connected to the side surface of the protective shell 201. A clamping block 211 is fixedly connected to one end of the rotating shaft 210 away from the protective shell 201. A positioning plate 214 is fixedly connected to the top of the protective shell 201. A damper 215 is fixedly connected to the top of the positioning plate 214. One end of the damper 215 away from the positioning plate 214 is fixedly connected to a support plate 217. A sliding rod 218 penetrates through the top of the support plate 217. The design and rotation mechanism of the cover plate 205 ensure that the bearing can be effectively sealed inside the protective shell 201 after installation. This sealing structure can prevent dust, moisture and other pollutants from entering the bearing, thereby extending the service life of the bearing and reducing the maintenance frequency. Through the mechanism of rotating the cover plate 205 and the rotating plate 208, convenient opening and closing operations can be achieved. When it is necessary to inspect or replace the bearing, the cover plate 205 can be easily opened without using complex tools or disassembling the entire protective shell 201, which improves the maintenance efficiency.

[0029] In this embodiment, by placing the bearing body 101 inside the protective shell 201, rotating the cover plate 205 to drive the mounting block 204 to rotate, so that the cover plate 205 covers the top of the protective shell 201. At this time, rotating the rotating plate 208 to drive the rotating rod 207 to rotate, so that the rotating shaft 210 is clamped into the card slot 209, and rotating the clamping block 211 to the vertical state can fix the cover plate 205. When it is necessary to take out the bearing, rotate the clamping block 211 to the horizontal state, rotate the rotating plate 208 to make the card slot 209 disengage from the rotating shaft 210, and the cover plate 205 can be opened, realizing the function of sealing the bearing. When the cover plate 205 covers down, the pressure generated squeezes the sliding rod 218 and the support plate 217, so that the sliding rod 218 moves downward. Then, the sliding rod 218 moves downward to squeeze the return spring 219. Through the elastic force of the return spring 219, the sliding rod 218 is reset, and the spring 216 is compressed, thereby converting the vibration energy into elastic potential energy. The spring 216 generates a reaction force opposite to the vibration direction to offset the vibration force, realizing the function of protecting the cover plate 205 and the protective shell 201.

[0030] Embodiment 2

[0031] AsFigures 3 to 5 As shown, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes a bearing sealing structure. An inner wall of a protective shell 201 is fixedly connected with a hydraulic cylinder 220. One end of the hydraulic cylinder 220 is slidably connected with a hydraulic rod 221 through a piston, and the other end of the hydraulic cylinder 220 is slidably connected with a force-receiving rod 222 through a piston. A force-receiving plate 224 is fixedly connected to a top of the force-receiving rod 222, and a pressing plate 225 is fixedly connected to one end of the hydraulic rod 221. A clamping groove 209 is formed in a side surface of a rotating plate 208, and a fixing plate 212 is fixedly connected to an inner wall of a cover plate 205. An extrusion block 213 is fixedly connected to a side surface of the fixing plate 212, and the force-receiving plate 224 is located on a movement track of the extrusion block 213. A reset spring 219 is fixedly connected to a bottom of a sliding rod 218, and one end of the reset spring 219 away from the sliding rod 218 is fixedly connected to a top of a positioning plate 214. A spring 216 is fixedly connected to a bottom of a support plate 217, and one end of the spring 216 away from the support plate 217 is fixedly connected to a top of the positioning plate 214. A compression spring 223 is fixedly connected to a circumferential surface of the force-receiving rod 222, and one end of the compression spring 223 away from the force-receiving rod 222 is fixedly connected to a side surface of the hydraulic cylinder 220. An initial state of the spring 216 is a relaxed state, the number of the springs 216 is set to two, and they are symmetric with respect to a vertical central axis of the positioning plate 214. A clamping block 211 is located on a movement track of the clamping groove 209, an initial state of the reset spring 219 is a relaxed state, the number of the fixing plates 212 is set to two, and they are symmetric with respect to a vertical central axis of the cover plate 205.

[0032] A bearing includes a bearing body 101. A sliding groove 104 is formed in a top of the bearing body 101, and rolling balls 102 are arranged on an inner wall of the sliding groove 104. A connecting rod 103 is fixedly connected to an inner wall of the bearing body 101. A hydraulic system and the pressing plate 225 are used to clamp the bearing body 101 to ensure that the bearing maintains a stable position and direction during operation. This is particularly important for equipment under high-speed operation or high-load working conditions, which can reduce damage and failures caused by bearing movement or loosening, help reduce vibrations of the equipment and the bearing during operation, and thus extend their service life and reduce maintenance costs.

[0033] In this embodiment, by rotating the cover plate 205 to drive the fixing plate 212 to rotate, and then by rotating the fixing plate 212 to drive the extrusion block 213 to rotate, the extrusion block 213 rotates to squeeze the force-receiving plate 224 to displace downward, and then the force-receiving plate 224 squeezes the force-receiving rod 222 to displace downward, so that the force-receiving rod 222 displaces inward to squeeze a piston inside the hydraulic cylinder 220. The piston inside the hydraulic cylinder 220 pushes the liquid inside it, and the liquid inside the hydraulic cylinder 220 pushes another piston to displace. The piston pushes the hydraulic rod 221 to displace, and the displacement of the hydraulic rod 221 pushes the pressing plate 225 to displace, and then the pressing plate 225 displaces to clamp the bearing body 101, realizing the function of fixing the bearing.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
