Description

Technical Field

[0001] This utility model relates to the field of oil slinger ring disassembly technology, specifically to a disassembly tool for bearing oil slinger rings. Background Technology

[0002] The bearings of the boiler blower drive motors in the ethylene power unit are all sliding bearings, lubricated by oil slinger ring splash lubrication. When maintaining the motor, the oil slinger rings need to be disassembled. The structure of the oil slinger ring is as follows: Figure 5 As shown, two semicircular rings are combined into a circle through a stepped joint and then connected by fastening screws. The elastic pin is to ensure the precise positioning of the two semicircular rings forming the circle. Because the installation tightness of the elastic pin is relatively large, disassembly is difficult. Usually, one of the semicircular rings is separated from the other by hitting it with a hard object. This method of disassembly by hitting with a hard object can easily damage the oil slinger ring. Frequent knocking can cause pits and dents, making the oil slinger ring jammed during operation, preventing it from properly slinging oil and leading to the bearing burning out. Utility Model Content

[0003] The purpose of this invention is to design a disassembly tool for bearing oil slingers, which can solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A disassembly tool for a bearing oil slinger ring includes a top plate. The bottom of the top plate has a first vertical plate and a second vertical plate arranged opposite to each other. The first vertical plate has a first through hole. The second vertical plate has a cylinder on the side facing away from the first vertical plate. The second vertical plate has a threaded hole aligned with the first through hole and penetrating the cylinder. A screw is threaded into the threaded hole. A push rod is connected to one end of the screw facing the first through hole, and two symmetrically arranged handles are provided at the other end.

[0006] Furthermore, the end of the screw facing the first through hole is provided with an internal hexagonal groove, and one end of the push rod is fixedly connected with an external hexagonal head that mates with the internal hexagonal groove.

[0007] Furthermore, a first rubber pad is affixed to the side of the first vertical plate facing the second vertical plate.

[0008] Furthermore, a clamping plate is provided between the first vertical plate and the second vertical plate, and a sliding hole extending along its length is provided on the top plate. A slider that slides with the sliding hole is provided on the top of the clamping plate, and a limiting rod is provided on the top of the slider. A second through hole aligned with the first through hole is provided on the clamping plate, and a fixing block is provided on the top of the top plate near the first vertical plate. The fixing block and the limiting rod are fixedly connected by a spring.

[0009] Furthermore, a second rubber pad is attached to the side of the clamp facing the first vertical plate.

[0010] Furthermore, the handle is a retractable structure.

[0011] Furthermore, the handle includes a first round rod, a second round rod, and a handle housing. The diameter of the first round rod is smaller than the diameter of the second round rod. One end of the first round rod is fixed to the screw, and the other end is fixedly connected to the second round rod. The handle housing has an inner cavity that accommodates the first round rod and the second round rod. The inner cavity and the second round rod are slidably fitted. A limiting ring is provided at the opening of the inner cavity. The first round rod has an external thread, and the inner wall of the limiting ring has an internal thread that is threadedly fitted with the external thread.

[0012] The beneficial effects of this utility model are as follows:

[0013] When disassembling the oil slinger ring, place it between the first and second vertical plates, then ensure the inner side of the first vertical plate contacts the oil slinger ring and aligns the first through hole with one end of the elastic pin. Rotate the screw using the handle, moving it within the threaded hole, which in turn moves the push rod closer to the elastic pin. Once the push rod contacts the end of the elastic pin furthest from the first through hole, continue rotating the screw. The push rod will then push the elastic pin closer to the first through hole, making disassembly of the elastic pin simple and convenient. This avoids the need to strike the oil slinger ring with hard objects, preventing damage and extending its service life. Attached Figure Description

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] like Figure 1-4 As shown, a disassembly tool for a bearing oil slinger ring includes a top plate 1. The bottom of the top plate 1 has a first vertical plate 2 and a second vertical plate 3 arranged opposite each other. The first vertical plate 2 has a first through hole 4 for aligning with an elastic pin 22, facilitating the ejection of the elastic pin 22. The second vertical plate 3 has a cylindrical body 5 on its side facing away from the first vertical plate 2. The second vertical plate 3 has a threaded hole 6 aligned with the first through hole 4 and penetrating the cylindrical body 5. A screw 7 is threaded into the threaded hole 6. A push rod 8 is connected to the end of the screw 7 facing the first through hole 4. By rotating the screw 7, it moves within the threaded hole 6, thereby driving the push rod 8 to move closer to the elastic pin 22. The push rod 8 can push the elastic pin 22; the other end of the screw 7 is provided with two symmetrically arranged handles 9, which can drive the screw 7 to rotate; the side of the first vertical plate 2 facing the second vertical plate 3 is affixed with a first rubber pad 12, which plays a buffering role and prevents the first vertical plate 2 from leaving pits on the oil slinger ring 21; the end of the screw 7 facing the first through hole 4 is provided with an internal hexagonal groove 10, and one end of the push rod 8 is fixedly connected to an external hexagonal head 11 that mates with the internal hexagonal groove 10. The push rod 8 of different diameters can be replaced according to the diameter of the elastic pin 22 to adapt to oil slinger rings of different sizes and improve practicality.

[0025] A clamping plate 13 is provided between the first vertical plate 2 and the second vertical plate 3. A sliding hole 14 extending along its length is provided on the top plate 1. A slider 15 that slides with the sliding hole 14 is provided on the top of the clamping plate 13. A limiting rod 16 is provided on the top of the slider 15. A fixing block 18 is provided on the top of the top plate 1 near the first vertical plate 2. The fixing block 18 and the limiting rod 16 are fixedly connected by a spring 19. The clamping plate 13 can be moved away from the first vertical plate 2 by pushing the limiting rod 16 by hand, thereby stretching the spring 19. After releasing the hand, the spring 19 will contract. When used, the clamping plate 13 can be moved closer to the first vertical plate 2, thereby clamping the first vertical plate 2 and the clamping plate 13 onto the oil slinger ring 21, which facilitates the fixation of the disassembly tool. When holding the top plate 1 by hand, it can prevent the first through hole 4 from being misaligned with the elastic pin 22 due to hand tremors, thus increasing practicality. The clamping plate 13 is provided with a second through hole 17 aligned with the first through hole 4, for the top rod 8 to pass through. The side of the clamping plate 13 facing the first vertical plate 2 is affixed with a second rubber pad 20, which plays a buffering role and prevents the clamping plate 13 from leaving pits on the oil slinger ring 21.

[0026] The handle 9 is a telescopic structure, comprising a first round rod 901, a second round rod 902, and a handle housing 903. The diameter of the first round rod 901 is smaller than the diameter of the second round rod 902. One end of the first round rod 901 is fixed to the screw 7, and the other end is fixedly connected to the second round rod 902. The handle housing 903 has an inner cavity 904 that accommodates the first round rod 901 and the second round rod 902. The inner cavity 904 and the second round rod 902 are slidably fitted. A limiting ring 905 is provided at the opening of the inner cavity 904. The first round rod 901 has an external thread 906, and the inner wall of the limiting ring 905 has an internal thread 907 that is threadedly fitted with the external thread 906. By rotating the handle housing 903, the limiting ring 905 can be moved on the first round rod 901, thereby extending or shortening the length of the handle 9. Extending the length of the handle 9 makes it easier to rotate the screw 7 with less effort.

[0027] Working principle:

[0028] like Figure 5 and 6As shown, when using the disassembly tool, push the limiting rod 16 by hand to move the clamping plate 13 away from the first vertical plate 2, thereby stretching the spring 19. Then, place the oil slinger ring 21 between the first vertical plate 2 and the clamping plate 13, aligning the first through hole 4 and the push rod 8 with the two ends of the elastic pin 22 respectively. After releasing the hand, under the contraction force of the spring 19, the clamping plate 13 can move closer to the first vertical plate 2, thereby clamping the first vertical plate 2 and the clamping plate 13 onto the oil slinger ring 21, thus fixing the disassembly tool onto the oil slinger ring. 21. Then, hold the top plate 1 with one hand and use the other hand to rotate the screw 7 through the handle 9, so that the screw 7 moves in the threaded hole 6, which can drive the push rod 8 to move closer to the elastic pin 22. After the push rod 8 contacts the end of the elastic pin 22 away from the first through hole 4, continue to rotate the screw 7. The push rod 8 will push the elastic pin 22 closer to the first through hole 4, making the elastic pin 22 easy to disassemble. This avoids hitting the oil slinger ring with hard objects, prevents damage to the oil slinger ring, and improves the service life of the oil slinger ring.
