Description

Technical Field

[0001] This application relates to the field of bearing technology, and in particular to a tooling and method for repairing deformation defects in the bearing sleepers of non-standard thrust bearings. Background Technology

[0002] As a critical piece of equipment for nuclear safety, the charging pump in the chemical and volume control system operates at speeds up to 4600 revolutions per minute, with vibration requirements of less than 5.6 mm / sec. Due to the extremely high rotational precision of the charging pump, the rotating components and thrust devices require very high accuracy. During maintenance, one reason for the substandard thrust clearance of the charging pump in the chemical and volume control system was found to be a protrusion on the semi-clamping ring at the mating surface of the two half-pillars of the thrust bearing. This caused the pillars to twist and deform, increasing the circumferential diameter of the thrust pillars. After installation into the bearing housing, deformation occurred, affecting the accuracy of the thrust clearance.

[0003] Because non-standard thrust bearing sleepers are non-standard components that are neither round nor square, they cannot be directly clamped and machined on a lathe, making it difficult to achieve precise dimensional tolerances, form and position tolerances, and surface finishes. Currently, the conventional method for handling sleeper deformation defects is to replace them with new spare parts and re-measure and adjust the thrust clearance. Since sleepers are non-standard components with poor adaptability, they are rarely purchased for inventory. If new sleepers are urgently procured for replacement, the lead time from ordering to assembly and adjustment is estimated to be at least fifteen days. Furthermore, if the charging pump in the chemical and volumetric control systems is unavailable, the power plant cannot start generating electricity. Therefore, the economic losses caused by excessively long maintenance cycles due to the loss of resources from directly replacing parts are substantial. Summary of the Invention

[0004] Therefore, it is necessary to provide a tooling and method for repairing deformation defects in non-standard thrust bearings.

[0005] As one aspect of this application, a fixture for repairing deformation defects in roof tile sleepers is provided, used to clamp the sleepers to be repaired onto a processing device; the sleeper includes two half-sleeves, with the open ends of the two half-sleeves facing each other; each half-sleeve has a semi-annular structure; the fixture for repairing deformation defects in roof tile sleepers includes:

[0012] As another method for repairing deformation defects in roof tiles according to this application, a method for repairing deformation defects in roof tiles as described above is provided, the method comprising the following steps:

[0013] The first side of the first half-sleeper is connected to the first mounting shaft hole of the tile deformation defect repair tool by a fastener, and the first side of the second half-sleeper is connected to the second mounting shaft hole of the tile deformation defect repair tool by a fastener; the open ends of the two half-sleepers are connected to each other; wherein, the first side of the half-sleeper is configured as the side of the half-sleeper that contacts the tile.

[0017] Using the outer circular surface of the half-tile pillow as a reference plane, the processing equipment repairs the deformation defect areas on the two half-tile pillows along the end faces of the second sides of the two half-tile pillows; wherein, the second side of the half-tile pillow is configured as one side of the half-tile pillow opposite to the tile.

[0018] In one embodiment, the depth to which the fastener extends into the first mounting shaft hole and the depth to which the fastener extends into the second mounting shaft hole are the same; wherein, the depth to which the fastener extends into the first mounting shaft hole and the depth to which the fastener extends into the second mounting shaft hole are 1mm to 3mm.

[0019] In one embodiment, both the threaded surfaces of the first mounting shaft hole and the threaded surfaces of the second mounting shaft hole are coated with molybdenum disulfide anti-seize agent.

[0020] In one embodiment, the step of detecting the real-time form and position errors of the tile deformation defect repair fixture and the two half-tiles, and determining that the real-time form and position errors of the tile deformation defect repair fixture and the two half-tiles are all within a preset deviation range includes the following sub-steps:

[0021] When the processing equipment rotates at a preset speed, the real-time form and position error of the tile deformation defect repair tooling and the two half-tiles is detected, and it is determined whether the real-time form and position error of the tile deformation defect repair tooling and the two half-tiles is within the preset deviation range.

[0022] When the real-time form and position errors of the tile deformation defect repair tool and the two half-tiles are outside the preset deviation range, the first reference form and position error, the second reference form and position error, and the third reference form and position error of the tile deformation defect repair tool and the two half-tiles are detected respectively at the first rotation speed, the second reference form and position error at the second rotation speed, and the third reference form and position error at the third rotation speed; wherein, the first rotation speed, the second rotation speed, and the third rotation speed increase or decrease sequentially.

[0023] When the deviation between the first reference form and position error, the second reference form and position error and the third reference form and position error is greater than the preset deviation, the fastening torque and installation sequence of the fastener are adjusted.

[0024] The real-time form and position errors of the tile deformation defect repair tool and the two half-tiles are detected again when the processing equipment rotates at a preset speed. The real-time form and position errors of the tile deformation defect repair tool and the two half-tiles are then determined to be within the preset deviation range.

[0026] In one embodiment, the sub-step further includes a sub-step after the processing equipment rotates at a preset speed to detect the real-time form and position error of the tile deformation defect repair fixture and the two half-tiles, and to determine whether the real-time form and position error of the tile deformation defect repair fixture and the two half-tiles is within a preset deviation range:

[0027] When the real-time form and position errors of the tile sleeper deformation defect repair tool and the two half-tile sleepers are still outside the preset deviation range, a compensation shim is installed between the half-tile sleeper and the tile sleeper deformation defect repair tool.

[0028] The real-time form and position errors of the tile deformation defect repair tool and the two half-tiles are detected again when the processing equipment rotates at a preset speed. It is then determined whether the real-time form and position errors of the tile deformation defect repair tool and the two half-tiles are within the preset deviation range.

[0029] It was determined that the real-time shape and position errors of the tile sleeper deformation defect repair tool and the two half-tile sleepers were all within the preset deviation range.

[0031] In one embodiment, the step involves detecting the real-time form and position errors of the tile deformation defect repair fixture and the two half-tiles when the processing equipment rotates at a preset speed, using a dial indicator or digital dial indicator to detect the real-time concentricity of the tile deformation defect repair fixture and the two half-tiles and / or the real-time perpendicularity of the tile deformation defect repair fixture and the two half-tiles.

[0032] In one embodiment, the step of repairing the deformed areas on the two half-sleeves using the outer circular surface of the tile mounting plate of the tile deformation defect repair fixture as a reference surface includes: the actuating end of the machining equipment performing turning machining on the deformed areas on the two half-sleeves along the outer circular surface of the two half-sleeves; wherein the single feed rate of the actuating end of the machining equipment is 0.004mm to 0.006mm; the step of repairing the deformed areas on the two half-sleeves using the outer circular surface of the half-sleeves as a reference surface includes: the actuating end of the machining equipment performing turning machining on the deformed areas on the two half-sleeves along the second side end face of the two half-sleeves; wherein the single feed rate of the actuating end of the machining equipment is 0.004mm to 0.006mm.

[0064] Figures 1 to 5 As shown, Figure 1 The diagram shows a front view of the structural schematic of the tooling for repairing deformation defects of roof tiles provided in one embodiment of this application. Figure 2 The diagram shows a top view of the tooling for repairing deformation defects in roof tiles provided in one embodiment of this application. Figure 3 It shows Figure 2 A schematic diagram of the structure of section AA in the middle. Figure 4 A schematic diagram of the assembly structure of the two half-sleeves and the tooling for repairing deformation defects of the half-sleeves is shown. Figure 5 It shows Figure 4 A partial structural diagram of the first half-sleeper provided in the image.

[0065] An embodiment of this application provides a tooling for repairing deformed tile sleepers, used to clamp the tile sleepers to be repaired onto a processing device; the tile sleeper includes two half-sleeves, with the open ends 23 of the two half-sleeves connected to each other; each half-sleeve has a semi-annular structure; the tooling for repairing deformed tile sleepers includes: a tile sleeper mounting plate, a positioning reference hole, a plurality of first mounting shaft holes, a plurality of second mounting shaft holes, and a third mounting shaft hole.

[0066] The tile restoring plate has a semi-annular structure. A boss structure is provided on the tile restoring plate along its central axis at the inner ring edge. Two half-tile restoring sections are respectively placed on the tile restoring plate and fitted onto the boss structure. A positioning reference hole is opened on the tile restoring plate and located outside the boss structure. The two half-tile restoring sections are located on both sides of the positioning reference hole, and the positioning reference hole corresponds to the position where the open ends 23 of the two half-tile restoring sections meet. Here, the open ends 23 of the two half-tile restoring sections are in contact to form a complete tile restoring structure. However, the tile restoring section and its two half-tile restoring sections are neither circular nor square. Multiple first mounting shaft holes are opened on the tile restoring plate along its central axis and located outside the boss structure. Multiple first mounting shaft holes are arranged on one side of the positioning reference hole along the circumference of the tile restoring plate. Multiple second mounting shaft holes are formed on the sleeper mounting plate along its central axis and located on the outer side of the boss structure; multiple second mounting shaft holes are arranged on the other side of the positioning reference hole along the circumference of the sleeper mounting plate. A third mounting shaft hole is formed on the sleeper mounting plate along its central axis and passes through the boss structure. The third mounting shaft hole is used for positioning and mounting the sleeper deformation defect repair tooling and the processing equipment. Here, the third mounting shaft hole 15 can be fitted onto the processing equipment or the processing equipment can be sleeved on the outer circumferential surface of the sleeper mounting plate.

[0067] In the tile deformation defect repair fixture provided in this embodiment, two half-tiles are respectively installed on the fixture through the first mounting shaft hole and the second mounting shaft hole, and the relative positions of the two half-tiles are positioned through the positioning reference hole. After the two half-tiles are installed on the tile deformation defect repair fixture, the fixture with the half-tiles installed is then installed on the processing equipment through the third mounting shaft hole.

[0068] See again Figure 5As shown, a semi-segmented limiting bolt 60 is installed at the open end of the half-sleeper. This semi-segmented limiting bolt 60 is fixed to the open end 23 of the half-sleeper using a countersunk screw 80, so that the semi-segmented limiting bolt 60 is embedded within the open end 23 of the half-sleeper. Generally, the cross-section end of the semi-segmented limiting bolt 60 does not protrude from the open end 23 of the half-sleeper. One end of the nut of the semi-segmented limiting bolt 60 extends into the positioning reference hole. The engagement between the positioning reference hole and the semi-segmented limiting bolt 60 achieves the limiting of the open end 23 of the half-sleeper. Simultaneously, in cases where the countersunk screw 80 is difficult to disassemble (e.g., the inner hole of the countersunk screw slips), the positioning reference hole can accommodate the nut of the semi-segmented limiting bolt 60 without affecting processing. It should be noted that one semi-segmented limiting bolt 60 can be installed on each of the two half-sleepers or one on any one half-sleeper.

[0069] It should be noted that, as Figure 2 The adapter disc fixture shown is mainly used to adapt and install the first half-sleeper 20 with five tile blocks 50 and the second half-sleeper 30 with four tile blocks. It can be seen that five first mounting shaft holes 13 are continuously provided on one side of the positioning reference hole 12 on the tile deformation defect repair fixture 10, and four second mounting shaft holes 14 are continuously provided on one side of the positioning reference hole 12 on the tile deformation defect repair fixture 10. The number and specifications of the first mounting shaft holes 13 and second mounting shaft holes 14 arranged on the tile deformation defect repair fixture are not specifically limited here, and can be adjusted according to the number and specifications of the tile blocks 50 arranged on the first half-sleeper 20 and the second half-sleeper 30.

[0070] In one embodiment of this application, the fasteners used when installing the two half-sleeves and the sleeve deformation defect repair fixture 10 can be of the same specification. The depth to which the fastener 40 is inserted into the first mounting shaft hole 13 and the depth to which the fastener 40 is inserted into the second mounting shaft hole 14 are the same; wherein, the depth to which the fastener 40 is inserted into the first mounting shaft hole 13 and the depth to which the fastener 40 is inserted into the second mounting shaft hole 14 are 1mm to 3mm. For example, the depth to which the fastener 40 is inserted into the first mounting shaft hole 13 and the depth to which the fastener 40 is inserted into the second mounting shaft hole 14 can be 1mm, 2mm, or 3mm. It should also be noted that after the fastener is screwed into the limiting bolt 70 on the first half-sleeve 20 (or the second half-sleeve 30), the thread does not protrude from the end face of the first half-sleeve 20 (or the second half-sleeve 30). Here, a threaded hole is provided at the position of the limiting bolt 70 on the first half-sleeve 20 (or the second half-sleeve 30), and the fastener 40 is screwed into the threaded hole.

[0071] See Figure 6 As shown, Figure 6A flowchart illustrating a method for repairing deformation defects in roof tile sleepers according to an embodiment of this application is shown. A method for repairing deformation defects in roof tile sleepers according to an embodiment of this application includes:

[0072] In step S100, the first sides 21 of the two half-tile rests are respectively mounted on the tile rest deformation defect repair fixture 10 using fasteners 40, and the open ends 23 of the two half-tile rests are aligned; wherein, the first side 21 of the half-tile rest is configured as the side of the half-tile rest that contacts the tile 50. (See reference here.) Figure 4 As shown, Figure 4 A schematic diagram of the assembly structure of the two half-sleeves and the tooling for repairing deformation defects of the half-sleeves is shown.

[0073] In step S200, the tile deformation defect repair fixture 10 is installed on the processing equipment, and the first sides 21 of the two half-tiles are both arranged opposite to the processing equipment.

[0074] Step S300: The real-time form and position errors of the tile deformation defect repair fixture 10 and the two half-tiles are detected respectively, and it is determined that the real-time form and position errors of the tile deformation defect repair fixture 10 and the two half-tiles are all within the preset deviation range.

[0075] In step S400, using the outer circular surface of the tile deformation defect repair fixture 10 as a reference surface, the processing equipment repairs the deformation defect areas on the two half-tiles along the outer circular surfaces of the two half-tiles.

[0076] In step S500, using the outer circular surface of the half-tile pillow as a reference surface, the processing equipment repairs the deformation defect areas on the two half-tile pillows along the end faces of the second side 22 of the two half-tile pillows; wherein, the second side 22 of the half-tile pillow is configured as one side of the half-tile pillow opposite to the tile 50.

[0077] In this application, two non-standard (non-circular and non-square) half-sleeves are installed on the sleeve deformation defect repair fixture 10, which allows the deformation defects on the half-sleeves to be repaired on the processing equipment. This improves the adaptability of the half-sleeves and enables the leveling, alignment, and fine grinding of irregular sleeves of non-standard thrust bearings, thereby improving work efficiency and shortening maintenance time.

[0078] In an optional embodiment, in step S300, a dial indicator or a digital dial indicator can be used to detect the real-time concentricity of the tile deformation defect repair fixture 10 and the two half-tiles and / or the real-time verticality of the tile deformation defect repair fixture 10 and the two half-tiles.

[0079] In an optional embodiment, in step S400, the machining equipment can be a lathe, and the lathe tool turns the deformed defect areas on the two half-bearings along the outer circular surface of the two half-bearings. During the turning process, a low speed gear can be selected for the feed (the specific value is not limited here, but can be selected according to the actual working conditions), and the single feed amount can be controlled between 0.004mm and 0.006mm.

[0080] In an optional embodiment, in step S500, the machining equipment can be a lathe, and the lathe tool performs turning on the deformed defect areas on the two half-bearings along the end faces of the second side 22 of the two half-bearings. During the turning process, a low speed gear can be selected for the feed (the specific value is not limited here, but can be selected according to the actual working conditions), and the single feed amount can be controlled between 0.004mm and 0.006mm.

[0081] Furthermore, the fastener 40 can be a positioning bolt. The tightening torque of the positioning bolt can be 14 Nm to 18 Nm. For example, the tightening torque of the positioning bolt can be 14 Nm, 15 Nm, 16 Nm, 17 Nm, or 18 Nm.

[0082] In one embodiment of this application, the threaded surfaces of the first mounting shaft hole 13 and the second mounting shaft hole 14 are both coated with molybdenum disulfide anti-seize agent.

[0083] In one embodiment of this application, step S300 includes the following sub-steps:

[0084] When the processing equipment rotates at a preset speed, the real-time form and position errors of the tile deformation defect repair fixture 10 and the two half-tiles are detected, and it is determined whether the real-time form and position errors of the tile deformation defect repair fixture 10 and the two half-tiles are within the preset deviation range.

[0085] When the real-time form and position errors of the sleeper deformation defect repair fixture 10 and the two half-sleeves are outside the preset deviation range, the fixture 10 and the two half-sleeves are respectively detected at a first reference form and position under a first speed state, a second reference form and position under a second speed state, and a third reference form and position under a third speed state; wherein the first speed, the second speed, and the third speed increase or decrease sequentially. It should be noted that the first speed, the second speed, and the third speed are not specifically limited and can be adjusted according to the actual working conditions. For example, the lathe can be controlled to perform three checks of the reference form and position error at high speed, medium speed, and low speed.

[0086] When the deviation between the first reference form and position error, the second reference form and position error, and the third reference form and position error exceeds the preset deviation, adjust the tightening torque and installation sequence of the fastener 40 (generally from the middle to both sides). It should be noted that there is no specific limitation on the preset deviation; it can be adjusted according to the actual working conditions.

[0087] The real-time form and position errors of the tile deformation defect repair fixture 10 and the two half-tiles are detected again when the processing equipment rotates at a preset speed. It is then determined whether the real-time form and position errors of the tile deformation defect repair fixture 10 and the two half-tiles are within the preset deviation range. If it is determined that the real-time form and position errors of the tile deformation defect repair fixture 10 and the two half-tiles are both within the preset deviation range, the debugging is complete.

[0088] If it is determined that the real-time form and position errors of the tile sleeper deformation defect repair fixture 10 and the two half-tile sleepers are still outside the preset deviation range, it is necessary to install a compensation shim between the half-tile sleeper and the tile sleeper deformation defect repair fixture 10. It should be noted that compensation shims of different thicknesses can be installed between the half-tile sleeper and the tile sleeper deformation defect repair fixture 10, and the compensation shims can be stainless steel strips.

[0089] The real-time form and position errors of the tile deformation defect repair fixture 10 and the two half-tiles are detected again when the processing equipment rotates at a preset speed. It is then determined whether the real-time form and position errors of the tile deformation defect repair fixture 10 and the two half-tiles are within the preset deviation range. If it is determined that the real-time form and position errors of the tile deformation defect repair fixture 10 and the two half-tiles are both within the preset deviation range, the debugging is completed.

[0090] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
