Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a self-lubricating structure for a hydro-generator bearing. Background Technology

[0002] A hydroelectric generator is a device that converts water energy into electrical energy, mainly used in hydroelectric power stations. Its working principle involves water flow driving a turbine to convert water energy into mechanical energy, which is then used by the turbine's shaft to drive the generator's rotor, converting the mechanical energy into electrical energy for output. Bearings play a crucial role in supporting and guiding the rotating components, and their lubrication directly affects the generator's operational stability, efficiency, and service life.

[0003] Currently, existing methods can only apply lubricating oil to the surface of the outer ring of the bearing. The lubricating oil cannot penetrate into the bearing to lubricate the balls, resulting in bearing wear and unstable operation. Utility Model Content

[0004] The purpose of this invention is to solve the problem of poor lubrication effect caused by the difficulty in timely and evenly applying lubricating oil to the surface of rolling elements, and to propose a self-lubricating structure for hydro-generator bearings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A self-lubricating structure for a hydro-generator bearing includes a housing. A bearing support is fixedly connected to one end of the housing. An outer bearing ring is fixedly embedded within the bearing support, and an inner bearing ring is rotatably connected within the outer bearing ring. A first groove is provided on the inner side of the outer bearing ring, and a second groove is provided on the outer circumference of the inner bearing ring. Multiple balls are rotatably embedded between the second groove and the first groove, and a retainer is sleeved between the balls. A liquid storage box is snapped onto one end of the outer bearing ring. The liquid storage box has a cavity, and multiple outlet pipes are sealed and inserted into one side of the liquid storage box. The other end of each outlet pipe is located between the first and second grooves. A pressing plate is slidably connected within the cavity. Multiple push rods are fixedly connected to one side of the pressing plate, and the other end of each push rod extends out of the liquid storage box. A rubber sealing ring is snapped onto the circumference of the pressing plate.

[0007] Furthermore, two fixing blocks are fixedly connected to the outer walls of both ends of the outer casing of the machine body, and fixing bolts are threaded into the top of the fixing blocks.

[0008] Furthermore, two lifting rings are fixedly connected to the top outer wall of the casing.

[0009] Furthermore, the top of the liquid storage box is provided with a filling tube, which is connected to the cavity.

[0010] Furthermore, a liquid level observation window is embedded on one side of the liquid storage box.

[0011] Furthermore, one end of each of the multiple push rods is fixedly connected to a handle, and the outer wall of the handle is provided with an anti-slip groove.

[0012] Furthermore, a drive shaft is inserted into one end of the outer casing of the machine body, and one end of the drive shaft is inserted into the inner bearing ring.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By pushing the handle, the extrusion plate and rubber sealing ring are moved, thereby pushing the lubricating oil in the cavity into the outlet pipe, and then inputting it from the outlet pipe into the first groove and the second groove, thereby lubricating the balls and reducing bearing wear.

[0015] 2. The liquid level observation window allows for monitoring of the lubricating oil usage in the reservoir, facilitating timely replenishment of lubricating oil and ensuring proper lubrication of the bearings. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A self-lubricating structure for a hydro-generator bearing includes a housing 1. One end of the housing 1 is fixed with a bearing support 4 by bolts. An outer bearing ring 5 is fixedly embedded in the bearing support 4. An inner bearing ring 6 is rotatably connected to the outer bearing ring 5. A first groove 501 is provided on the inner side of the outer bearing ring 5. A second groove 601 is provided on the outer circumferential wall of the inner bearing ring 6. A plurality of balls 7 are rotatably embedded between the second groove 601 and the first groove 501. A cage 8 is sleeved between the plurality of balls 7. The cage 8 refers to a bearing part that partially wraps all or part of the rolling elements and moves with them, used to isolate the rolling elements, and usually also guides the rolling elements and keeps them in the bearing.

[0024] One end of the outer bearing ring 5 is snapped with a liquid storage box 9. The liquid storage box 9 has a cavity 10 inside. A plurality of liquid outlet tubes 16 are sealed and inserted into one side of the liquid storage box 9. The other end of the liquid outlet tube 16 is located between the first groove 501 and the second groove 601. The liquid outlet tube 16 has a needle tube structure, does not contact the bearing structure, and will not interfere with the rotation of the bearing.

[0025] A squeezing plate 14 is slidably connected inside the cavity 10. Multiple push rods 18 are integrally formed on one side of the squeezing plate 14. The other end of the push rods 18 extends out of the liquid storage box 9. A handle 13 is integrally formed on one end of the multiple push rods 18. A rubber sealing ring 15 is engaged around the circumference of the squeezing plate 14. Pushing the handle 13 moves the squeezing plate 14 and the rubber sealing ring 15, thereby pushing the lubricating oil in the cavity 10 into the liquid outlet pipe 16, and then inputting it from the liquid outlet pipe 16 into the first groove 501 and the second groove 601, thereby lubricating the ball 7.

[0026] Two fixing blocks 2 are welded to the outer walls of both ends of the outer casing 1. Fixing bolts are threaded into the top of the fixing blocks 2. The outer casing 1 is fixed and installed by fixing blocks 2 and fixing bolts. Two lifting rings 3 are welded to the top outer wall of the outer casing 1 to facilitate the hoisting of the outer casing 1.

[0027] The top of the liquid storage box 9 is provided with a filling tube 11, which is connected to the cavity 10. The top end of the filling tube 11 is threaded with a sealing cap. By unscrewing the sealing cap, lubricating oil can be injected into the cavity 10 inside the liquid storage box 9 from the filling tube 11. A liquid level observation window 12 is embedded on one side of the liquid storage box 9 to observe the usage of lubricating oil in the liquid storage box 9, so as to facilitate timely replenishment of lubricating oil. The outer wall of the handle 13 is provided with anti-slip grooves to facilitate operation of the handle 13. One end of the outer shell 1 is connected to a drive shaft 17, and one end of the drive shaft 17 is connected to the inner bearing ring 6.

[0028] The working principle of this embodiment is as follows: When in use, unscrew the sealing cap and inject lubricating oil into the cavity 10 inside the reservoir 9 through the filling tube 11. After injection, tighten the sealing cap to seal the filling tube 11. Then, push the handle 13 to move the extrusion plate 14 and the rubber sealing ring 15, thereby pushing the lubricating oil in the cavity 10 into the outlet tube 16, and then inputting it from the outlet tube 16 into the first groove 501 and the second groove 601, thereby lubricating the ball bearing 7.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
