Description

Technical Field

[0001] This utility model relates to the field of bearing lubrication technology, specifically to an automated steam turbine bearing lubrication device. Background Technology

[0002] Turbine bearings are important components of steam turbines, undertaking the crucial functions of supporting the rotor, bearing loads, and determining the rotor's position.

[0003] Steam turbine bearings require lubrication after prolonged use. Currently, lubrication is achieved by using absorbent cotton strips that come into contact with the bearing. However, friction occurs between the cotton strips and the bearing during rotation, leading to wear and tear on the strips over time, preventing them from making proper contact with the bearing and thus hindering lubrication. Additionally, the cotton strips only make contact on one side of the bearing, resulting in incomplete lubrication. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an automated turbine bearing lubrication device, in which a portion of the bearing to be lubricated can be immersed in lubricating oil, and the lubrication operation can be completed quickly by rotation, thereby solving the problems mentioned in the background art.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses an automated turbine bearing lubrication device, comprising a bearing 1 to be lubricated, an electric slide table 7, and multiple rotating shafts 2. One end of each rotating shaft 2 is inserted into the inner ring of the bearing 1 to be lubricated. A limiting ring 3 is installed on each rotating shaft 2 near the bearing 1 to be lubricated. Multiple ball grooves are provided on the opposite surfaces of the limiting rings 3, and balls 17 are movably installed in each ball groove. A portion of each ball 17 extends to the outside and contacts the side of the bearing 1 to be lubricated. A shaft 4 is installed on the other end of each rotating shaft 2. A ball bearing 5 is installed on the end of the shaft 4 away from the rotating shaft 2. An adjusting frame 6 is installed on the outside of each ball bearing 5. The other end of the adjusting frame 6 is fixedly connected to the platform on the electric slide table 7. A fixed seat 15 is located in the middle of the electric slide table 7. A cylinder 9 for moving the bearing 1 to be lubricated up and down is installed on the fixed seat 15. An upward lifting component is installed on the outside of the cylinder 9. When the rotating shaft moves inward, the balls on the limiting rings can contact the side of the bearing to be lubricated, thereby centering the bearing to be lubricated.

[0020] The electric slide has a dual-platform structure, and the two platforms move inward or outward synchronously, thereby driving the movement of the adjustment frame.

[0021] In this embodiment, the lifting assembly includes a first fixed frame 10, a second fixed frame 11, a rotating seat 12, a first motor 14, and multiple fixing blocks 13. The first fixed frame 10 is installed outside the cylinder 9. The end face of the second fixed frame 11 is in contact with the end face of the first fixed frame 10. The end of the second fixed frame 11 away from the first fixed frame 10 is bent to form a fixing part. The fixing part is provided with multiple fixing holes. Multiple fixing blocks 13 are installed on the second fixed frame 11. The rotating seat 12 is installed on the first fixed frame 10. One end of the rotating seat 12 extends between the fixing blocks 13. The first motor 14 is installed on one side of the fixing block 13. The rotating shaft 2 of the first motor 14 is fixedly connected to the rotating seat 12. A sealed bearing is embedded in one side of the fixing block. The rotating shaft of the first motor can be installed in the inner ring of the sealed bearing, which can provide support for the motor shaft.

[0022] In this embodiment, a socket is provided on the end face of the rotating shaft 2 on one side, and a plug portion 18 is protruding on the end face of the rotating shaft 2 on the other side. The plug portion 18 is inserted into the socket. The cross-section of the plug portion 18 and the socket is set in a polygonal structure. The rotating shafts on both sides are connected by the plug portion and the socket, so that the rotating shafts can rotate synchronously.

[0023] In this embodiment, a second motor 16 connected to the shaft 4 is installed on the adjustment frame 6 on one side. The second motor drives the shaft to rotate, and the rotation of the shaft synchronously drives the rotating shaft and the bearing to be lubricated.

[0024] In this embodiment, the adjustment frame 6 is provided with a weight reduction port in the middle, which reduces the material usage and cost of the adjustment frame.

[0025] In use, the retracting cylinder lifts the rotating shaft. After lifting, the first motor is started, which drives the rotating seat, the first fixed frame, and the cylinder. The cylinder then drives the adjusting frame and the rotating shaft, allowing the rotating shaft to tilt upwards. This moves the device from the center of the oil tank to the edge of the oil tank, facilitating the installation of the bearing to be lubricated. During installation, the electric slide is started, which drives the adjusting frame and the rotating shaft to open outwards, allowing the bearing to be lubricated to move between the rotating shafts. After the electric slide is started in the reverse direction, it drives the rotating shafts to close inwards until the opposite ends of the rotating shafts are inserted into the inner ring of the bearing to be lubricated, and the insertion part is inserted into the insertion hole, connecting the rotating shafts on both sides.

[0026] After the first motor starts in reverse, it can move the bearing to be lubricated from the edge of the oil sump to the middle. After the cylinder starts, it can move the bearing to be lubricated down, so that part of the bearing to be lubricated is immersed in the lubricating oil. At this time, the second motor can be started. The start of the second motor drives the shaft, the rotating shaft and the bearing to be lubricated. The lubricating oil is carried by the rotating bearing to be lubricated and then flows back to the oil sump to ensure the uniformity of the lubricating oil coverage.

[0027] After automatic lubrication, the bearing to be lubricated can be raised again and tilted upwards, allowing it to move from the center to the edge, facilitating its disassembly.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
