Description

Technical Field

[0001] This utility model relates to the field of bearing replacement tooling technology, specifically a generator bearing replacement tooling. Background Technology

[0002] The principle of generators is mainly based on the laws of electromagnetic induction and electromagnetic force. DC generators work by using external mechanical force to rotate conductor coils in a magnetic field. The coils continuously cut magnetic field lines, generating an induced electromotive force. When the windings rotate 90°, the two winding sides are at the physical neutral plane of the magnetic field, the brushes do not contact the commutator segments, and no current flows through the windings. When the windings rotate another 90°, the current direction changes due to the external mechanical force, and this cycle repeats, converting mechanical energy into DC electrical energy output. AC generators consist of a stator and a rotor. The stator is a fixed component containing a set of electrical conductors wound around an iron core. The rotor is a moving component that generates a rotating magnetic field in one of three ways: through induction (common in large generators using brushless AC generators), through permanent magnets (common in small AC generators), or using an exciter (a small DC power supply that powers the rotor through conductive slip rings and brush assemblies). The rotor generates a moving magnetic field around the stator, inducing a voltage difference between the stator windings, thus producing AC output. When repairing generators, a generator bearing replacement fixture is needed.

[0003] Different models of wind turbine generators have different models. When using a lead screw to pull out components such as slip rings, end caps, and tensioning sleeves, special tooling needs to be made for each type of wind turbine generator because the sizes of slip rings, end caps, and tensioning sleeves are different. This results in a waste of time and money to make tooling. Utility Model Content

[0004] The purpose of this utility model is to provide a generator bearing replacement fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a generator bearing replacement fixture, comprising a rectangular plate,

[0006] A side plate fixedly installed on the side wall of the rectangular plate;

[0007] And a replacement component located on the side of the rectangular plate;

[0008] The replacement component includes an adjustment mechanism located on the side of the rectangular plate;

[0009] A replacement mechanism is provided on the side of the rectangular plate.

[0010] Preferably, the adjusting mechanism includes a bidirectional threaded rod, one end of which is rotatably connected to the inner wall of the side plate via a bearing, a turntable is fixedly installed at one end of the bidirectional threaded rod, an adjusting plate is installed on the side wall of the bidirectional threaded rod, a slider is fixedly installed on the side wall of the adjusting plate, and a mortise block is fixedly installed at the bottom of the slider.

[0011] Preferably, the side wall of the bidirectional threaded rod is threadedly connected to the inner wall of the adjusting plate, and a turntable is fixedly installed at one end of the bidirectional threaded rod.

[0012] Preferably, the sidewall of the adjusting plate is slidably connected to the sidewall of the rectangular plate, the sidewall of the slider is slidably connected to the inner wall of the rectangular plate, and the top of the collateral block is slidably connected to the bottom of the rectangular plate.

[0013] Preferably, there are two collateral blocks, both of which are of equal shape and size, and are symmetrically arranged with respect to the center plane of the rectangular plate in the left-right direction.

[0014] Preferably, the side wall of the bidirectional threaded rod is rotatably mounted with a bearing connecting seat via a bearing. The side wall of the bearing connecting seat is fixedly connected to the side wall of the rectangular plate. A triangular reinforcement is fixedly mounted on the side wall of the bearing connecting seat. The side wall of the triangular reinforcement is fixedly connected to the side wall of the rectangular plate. By setting the bearing connecting seat, the stability of the bidirectional threaded rod can be improved. The stability of the bearing connecting seat can be effectively improved by the triangular reinforcement.

[0015] Preferably, the replacement mechanism includes a lead screw, which is threadedly connected to the inner wall of the rectangular plate through a threaded hole. A connecting seat is rotatably mounted on the bottom of the lead screw via a bearing, and an internal hexagon block is fixedly mounted on the top of the connecting seat.

[0016] Preferably, a collar is fixedly installed on the side wall of the internal hexagonal block, and a handle is fixedly installed on the side wall of the collar.

[0017] Preferably, there are six handles, which are evenly distributed on the side wall of the collar.

[0018] Preferably, there are two side plates, both of which are of equal shape and size, and are symmetrically arranged with respect to the midpoint of the rectangular plate in the left-right direction.

[0019] This utility model provides a generator bearing replacement fixture. It has the following advantages:

[0020] (1) In this utility model, the distance between the collateral blocks is adjusted by the operator according to the size of the bearing. The operator rotates the turntable, which in turn drives the position of the bidirectional threaded rod to rotate. Since the side wall of the bidirectional threaded rod is threadedly connected to the inner wall of the adjusting plate, the bidirectional threaded rod will drive the side wall of the adjusting plate to move when it rotates. The adjusting plate will drive the position of the slider to move, and the slider will drive the position of the collateral blocks to slide, thus quickly adjusting the distance between the two collateral blocks. When replacing components such as slip rings, end covers, and tension sleeves of different generator models, the position of the internal hexagon block can be directly rotated. One end of the connecting seat will contact one end of the generator, and the internal hexagon block will drive the threaded rod to rotate. The position of the rod is rotated. Since the side wall of the lead screw is threadedly connected to the inner wall of the rectangular plate, the rotation of the lead screw will drive the position of the rectangular plate to move. The rectangular plate will further drive the position of the collateral block to pull out the generator's slip ring, end cover, tension sleeve and other components. When pulling out the generator's slip ring, end cover, tension sleeve and other components, the force-bearing nut of the tooling can be evenly stressed, allowing the generator's slip ring, end cover, tension sleeve and other components to be pulled out. It can also quickly replace and disassemble the bearing. This solves the problem that when using a lead screw to pull out slip ring, end cover, tension sleeve and other components of different wind turbine generator models, because the slip ring, end cover, tension sleeve and other components are different sizes, each wind turbine generator needs to be made with special tooling, which is time-consuming and costly.

[0021] (2) By setting an internal hexagonal block, the operator can better rotate the position of the lead screw. The collar and handle on the side wall can improve the rotation effect of the lead screw, making it easier for the operator to use the device. Attached Figure Description

[0030] Side plates 2 are fixedly installed on the side wall of rectangular plate 1. There are two side plates 2, and the two side plates 2 are equal in shape and size. The two side plates 2 are symmetrically arranged with respect to the middle surface of the rectangular plate 1 in the left and right directions.

[0031] And the replacement component 4 is located on the side of the rectangular plate 1;

[0032] Replacement component 4 includes an adjustment mechanism 41 located on the side of rectangular plate 1;

[0033] A replacement mechanism 42 is provided on the side of the rectangular plate 1.

[0034] The adjusting mechanism 41 includes a bidirectional threaded rod 413. One end of the bidirectional threaded rod 413 is rotatably connected to the inner wall of the side plate 2 via a bearing. A turntable 416 is fixedly installed at one end of the bidirectional threaded rod 413. An adjusting plate 415 is installed on the side wall of the bidirectional threaded rod 413. A slider 414 is fixedly installed on the side wall of the adjusting plate 415. A collateral block 417 is fixedly installed at the bottom of the slider 414.

[0035] In this embodiment, the side wall of the bidirectional threaded rod 413 is threadedly connected to the inner wall of the adjusting plate 415, and a turntable 416 is fixedly installed at one end of the bidirectional threaded rod 413.

[0036] Furthermore, the side wall of the adjusting plate 415 is slidably connected to the side wall of the rectangular plate 1, the side wall of the slider 414 is slidably connected to the inner wall of the rectangular plate 1, and the top of the mortise block 417 is slidably connected to the bottom of the rectangular plate 1.

[0037] Furthermore, there are two collateral blocks 417, both of which are equal in shape and size, and are symmetrically arranged with respect to the center face of the rectangular plate 1 in the left-right direction.

[0038] Furthermore, a bearing connecting seat 412 is rotatably mounted on the side wall of the bidirectional threaded rod 413 via a bearing. The side wall of the bearing connecting seat 412 is fixedly connected to the side wall of the rectangular plate 1. A triangular reinforcement 411 is fixedly mounted on the side wall of the bearing connecting seat 412. The side wall of the triangular reinforcement 411 is fixedly connected to the side wall of the rectangular plate 1. By setting the bearing connecting seat 412, the stability of the bidirectional threaded rod 413 can be improved. The stability of the bearing connecting seat 412 can be effectively improved by the triangular reinforcement 411.

[0039] Example 2: Based on Example 1, a preferred embodiment of the generator bearing replacement fixture provided by this utility model is as follows: Figures 1 to 5 As shown: The replacement mechanism 42 includes a lead screw 421, which is threadedly connected to the inner wall of the rectangular plate 1 through a threaded hole. The bottom of the lead screw 421 is rotatably mounted with a connecting seat 422 via a bearing, and the top of the connecting seat 422 is fixedly mounted with an internal hexagon block 423.

[0040] In this embodiment, a collar 425 is fixedly installed on the side wall of the internal hexagon block 423, and a handle 424 is fixedly installed on the side wall of the collar 425.

[0041] Furthermore, there are six handles 424, which are evenly distributed on the side wall of the collar 425.

[0042] In practical implementation, when the operator uses the device, they first adjust the distance between the collateral blocks 417 according to the size of the bearing. The operator then rotates the turntable 416, which in turn rotates the position of the bidirectional threaded rod 413. Since the side wall of the bidirectional threaded rod 413 is threadedly connected to the inner wall of the adjusting plate 415, the rotation of the bidirectional threaded rod 413 will move the side wall of the adjusting plate 415. The adjusting plate 415 will move the position of the slider 414, which in turn will slide the position of the collateral blocks 417, quickly adjusting the distance between the two collateral blocks 417. This adjustment is applicable to different types of generators. When replacing components such as the slip ring, end cover, and tension sleeve of the generator, the position of the internal hexagon block 423 can be directly rotated. One end of the connecting seat 422 will contact one end of the generator, and the internal hexagon block 423 will drive the position of the lead screw 421 to rotate. Since the side wall of the lead screw 421 is threadedly connected to the inner wall of the rectangular plate 1, when the lead screw 421 rotates, it will drive the position of the rectangular plate 1 to move. The rectangular plate 1 will further drive the position of the mortise block 417 to pull out the generator's slip ring, end cover, tension sleeve, and other components. When pulling out the generator's slip ring, end cover, tension sleeve, and other components, the force-bearing nut of the tooling can be evenly stressed, pulling out the generator's slip ring, end cover, tension sleeve, and other components. Bearings can also be quickly replaced and disassembled.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
