Description

Technical Field

[0001] The utility model relates to the technical field of generator bearing maintenance, in particular to a generator bearing quick-release assembly. Background Art

[0002] Generator bearings are key components in generator sets. They carry the rotation and support of the rotor and have an important impact on the normal operation and stability of the generator set. With the continuous increase in the power and speed of the generator set, the technical requirements for generator bearings are also getting higher and higher. Therefore, it is necessary to disassemble and maintain the generator bearings regularly to keep their stable performance and ensure the stable operation of the generator.

[0003] The existing generator bearing disassembly structure mainly includes bearing locking devices, disassembly tools, bearing extractors and other parts. For example, the Chinese patent with publication number CN218747519U, entitled: A generator repair bearing disassembly device, is to put the lower end of the claw under the bearing, place a top pad on the upper axial surface of the generator, and then insert the square nut into the square hole of the crossbeam frame, align the two holes, and at the same time insert the handle into the screw rod hole, screw the screw rod into the square nut and then screw it into the top pad threaded hole, then rotate the handle clockwise, the lower end of the screw rod pushes the top pad and the bearing to make relative movement, and the bearing can be pulled out. However, before it is used and disassembled, it is first necessary to use a rope or cord to fix the generator rotor to prevent it from rotating and ensure stability during the disassembly process. Only then can a wrench be used to remove the corresponding end cover of the bearing. At this time, a bearing disassembly tool is placed in the gap of the bearing outer ring, and force is applied to the bearing outer ring to pull it out inward. Finally, the motor is placed inside the disassembly device for disassembly, so that the overall disassembly steps require advanced preparation operations before the motor can be placed inside the disassembly structure for disassembly. As a result, the overall disassembly process is not coherent, and the installation steps of the motor during disassembly are increased, making the overall process more cumbersome and complicated, and increasing certain labor and time costs. Therefore, the present application provides a generator bearing quick-release assembly to meet the needs. Utility Model Content

[0004] The purpose of the present application is to provide a generator bearing quick-release assembly, which solves the problem of cumbersome and complicated pre-use preparation work in the prior art, and achieves the purpose of simplifying the overall disassembly steps and making it more convenient to disassemble.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a generator bearing quick-release assembly, comprising a mounting base, the mounting base is fixedly connected to a placing platform, and the top of the placing platform is slidably connected to two clamping fixings, the clamping fixings are used to clamp and fix the motor rotor, the side wall of the mounting base is slidably connected to a sliding seat via an electric slide rail, and the top of the sliding seat is fixedly connected to a mounting member, the interior of the mounting member is fixedly connected to a linear drive, and the free end of the linear drive is fixedly connected to a driving member, both sides of the driving member are fixedly connected to interference fixings via an electric telescopic rod, and the electric telescopic rod is used to drive the interference fixings to clamp and fix the motor bearing, a hollow member is rotatably connected to the mounting base via a driving motor, and two clamping plates are arranged inside the hollow member, and the clamping plates are used to limit the motor end cover.

[0007] Preferably, an anti-slip piece is fixedly connected to one opposite side of the two clamping fixing pieces, and a plurality of anti-slip convex strips are fixedly connected to the anti-slip piece.

[0008] Preferably, a plurality of guide openings are provided on the top of the placement platform, and a plurality of guide blocks are fixedly connected to the bottom of the clamping fixture, and the guide blocks are slidably connected inside the guide openings.

[0009] Preferably, a plurality of heating plates are fixedly connected to opposite sides of the two clamping plate bodies through mounting openings, and the same heat spreader is fixedly connected to adjacent heating plates.

[0010] Preferably, through openings are provided at the top and bottom of the hollow member, and an adjusting member is slidably inserted inside the through opening, the free end of the adjusting member is fixedly connected to the clamping plate, and a limiting structure is fixedly connected to the adjusting member.

[0011] Preferably, the limiting structure includes positioning holes opened on the side walls of the hollow member and the adjusting member, and the number of positioning holes on the adjusting member is several, the hollow member is connected with the positioning member through the mounting base, and the free end of the positioning member passes through the positioning holes and penetrates both sides of the adjusting member.

[0012] In summary, the technical effects and advantages of the utility model are:

[0013] The utility model has a reasonable structure. By providing a linear drive and a resistance fixing part, the linear drive can be directly driven during use to push the driving part to be inserted into the inside of the motor bearing. Then, when the driving part is inserted into a suitable position inside the bearing, the electric telescopic rod can be directly controlled by an external controller, so that the two electric telescopic rods are forced to move away from each other, thereby contacting and fitting with the inner wall of the motor bearing. At this time, the driving part can be driven to retract by the linear drive, and its retraction force can be transmitted to the motor bearing through the electric telescopic rod and the resistance fixing part, so that the bearing is stressed and moves under the action of its force, thereby reducing the capture of manual disassembly and achieving the effect of quick disassembly.

[0014] In the utility model, by arranging a driving motor and a heating plate, before use, the adjusting member can be pushed to make it slide along the through-hole under force, and then the clamping plate body can be pushed to move inside the hollow member, so that the clamping plate body and the motor end cover are more closely fitted. At this time, the hollow member can be directly driven to rotate by the driving motor, and its rotational force will act on the motor end cover through the clamping plate body, so that the motor end cover can be rotated and disassembled under the action of its rotational force. At the same time, if the bearing to be processed is a large or tightly fitted bearing, the heating plate can be effectively controlled by an external controller, so that the heating plate enters a working state for heating. The heat of the heating plate can be effectively transferred to the heat spreader, so that the heat spreader evens out its heat, and the evenly distributed heat acts on the outer ring of the bearing. At this time, the outer ring of the bearing will expand due to the heat, thereby improving the convenience of disassembly.

[0015] In the utility model, a clamping fixture is provided through an electric push rod, and the electric push rod can be directly controlled by an external controller during use, so that the electric push rod effectively pushes the clamping fixture to move linearly along the top of the placement platform, and then adjusts the movement trajectory of the clamping fixture, so that the clamping fixture is subjected to force to clamp the rotor of the motor in and out, and a limiting force is applied to the motor rotor to ensure the stability of the rotor during disassembly.

[0028] Combine the following Figure 1-4 The embodiment shown describes the technical solution of the utility model:

[0029] It includes a mounting base 1, which is fixedly connected to a placing platform 2, and the top of the placing platform 2 is slidably connected to two clamping fixings 3, the clamping fixings 3 are used to clamp and fix the motor rotor, the side wall of the mounting base 1 is slidably connected to a sliding seat 5 through an electric slide rail 4, and the top of the sliding seat 5 is fixedly connected to a mounting member 6, the interior of the mounting member 6 is fixedly connected to a linear drive 7, and the free end of the linear drive 7 is fixedly connected to a driving member 8, both sides of the driving member 8 are fixedly connected to a conflicting fixing member 10 through an electric telescopic rod 9, and the electric telescopic rod 9 is used to drive the conflicting fixing member 10 to clamp and fix the motor bearing, a hollow member 12 is rotatably connected to the mounting base 1 through a driving motor 11, and two clamping plates 13 are arranged inside the hollow member 12, and the clamping plate 13 is used to limit the motor end cover.

[0030] When it is in use, the mounting base 1 can be directly placed on a plane, and then the motor to be processed can be directly placed on the top of the placement platform 2. At this time, the clamping fixture 3 can be directly pulled to clamp the motor's rotor in and out, thereby ensuring the stability of the rotor during disassembly. The electric slide rail 4 and the drive motor 11 can be effectively controlled by an external controller. When the clamping plate 13 is about to contact the end cover of the motor, the drive motor 11 can directly drive the hollow part 12 to rotate, and its rotational force will act on the motor end cover through the clamping plate 13, so that the motor end cover can be rotated and disassembled under the action of its rotational force. At the same time, the electric slide rail 4 can also drive the line through the sliding seat 5 and the mounting part 6 under the action of its external control force. The linear drive 7 moves, and the linear drive 7 and the connected driving member 8 and the abutting fixing member 10 move synchronously. When the driving member 8 moves to the central axis of the motor, the linear drive 7 can be directly driven to push the driving member 8 to be inserted into the inside of the motor bearing. Then, when the driving member 8 is inserted into a suitable position inside the bearing, the electric telescopic rod 9 can be directly controlled by an external controller, so that the two electric telescopic rods 9 are forced to move away from each other, thereby abutting and fitting with the inner wall of the motor bearing. At this time, the driving member 8 can be driven to retract by the linear drive 7, and its retraction force can be transmitted to the motor bearing through the electric telescopic rod 9 and the abutting fixing member 10, so that the bearing is stressed and moves under the action of its force, thereby achieving the effect of quick disassembly.

[0031] Side mounting plates 19 are fixedly connected to both sides of the mounting base 1 , and side walls of the side mounting plates 19 are fixedly connected to side walls of the clamping fixture 3 via a plurality of electric push rods 20 .

[0032] During its use, the electric push rod 20 can be directly controlled by an external controller, so that the electric push rod 20 effectively pushes the clamping fixture 3 to move linearly along the top of the placement platform 2, and then effectively adjusts and limits the movement trajectory of the clamping fixture 3, making the clamping fixture 3 more stable and convenient during adjustment and use, and also increasing its limiting force on the motor rotor.

[0033] The two clamping fixing members 3 are fixedly connected to the opposite side with anti-skid members 21 , and the anti-skid members 21 are fixedly connected to a plurality of anti-skid convex strips.

[0034] During its use, the provision of the anti-slip member 21 can effectively increase the contact friction between the motor rotor and the clamping fixture 3, making it more stable during use. At the same time, the anti-slip convex strips cooperate with each other to improve the overall fixing effect to a certain extent.

[0035] A plurality of guide openings 22 are formed on the top of the placement platform 2 , and a plurality of guide blocks 23 are fixedly connected to the bottom of the clamping fixture 3 . The guide blocks 23 are slidably connected to the inside of the guide openings 22 .

[0036] When the clamping fixture 3 is subjected to force to slide along the top of the mounting base 1, the sliding force of the clamping fixture 3 can be effectively transmitted to the guide block 23, so that the guide block 23 slides along the guide opening 22 under the action of its force. At this time, the setting of the guide opening 22 will limit the moving trajectory of the clamping fixture 3, thereby ensuring the stability of the clamping fixture 3 during the sliding adjustment and avoiding the possibility of its displacement or tilt.

[0037] A plurality of heating plates 14 are fixedly connected to one side of two opposite clamping plates 13 through mounting openings, and a same heat spreader 15 is fixedly connected to adjacent heating plates 14 .

[0038] During its use, if the bearing to be treated is a large or tightly fitted bearing, the heating plate 14 can be effectively controlled by an external controller so that the heating plate 14 enters a working state for heating. The heat of the heating plate 14 can be effectively transferred to the heat spreader 15, so that the heat spreader 15 can evenly distribute its heat and apply the evenly distributed heat to the outer ring of the bearing. At this time, the outer ring of the bearing will expand due to the heat, thereby improving the convenience of its disassembly.

[0039] Through openings are provided at the top and bottom of the hollow member 12 , and an adjusting member 16 is slidably inserted inside the through opening. The free end of the adjusting member 16 is fixedly connected to the clamping plate 13 , and a limiting structure is fixedly connected to the adjusting member 16 .

[0040] Before use, the adjusting member 16 can be directly pushed to slide along the through-hole under force, and then the clamping plate 13 can be pushed to move inside the hollow member 12, so that the clamping plate 13 and the motor end cover are more closely fitted, thereby improving the support and fixing effect of the clamping plate 13.

[0041] The limiting structure includes positioning holes 17 opened on the side walls of the hollow member 12 and the adjusting member 16, and the number of positioning holes 17 on the adjusting member 16 is several. The hollow member 12 is plugged with a positioning member 18 through the mounting base 1, and the free end of the positioning member 18 passes through the positioning holes 17 and penetrates both sides of the adjusting member 16.

[0042] During the disassembly of the motor end cover, the positioning piece 18 can be directly pushed so that the positioning piece 18 is forced to be inserted along the positioning hole 17 between the hollow piece 12 and the adjusting piece 16, thereby forming a plug-in structure, limiting the relative position between the adjusting piece 16 and the hollow piece 12, and increasing the stability of the clamping plate 13 during use to a certain extent, thereby avoiding the possibility of it being offset or falling off.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
