Description

Technical Field

[0001] This utility model relates to the field of generator rotor technology, and in particular to a generator rotor assembly that is easy to install. Background Technology

[0002] A generator is a device that converts mechanical energy into electrical energy. Its core components include a stator assembly and a rotor assembly. The rotor assembly typically consists of a shaft and components such as a rotor core, magnets, or windings fixedly mounted on it. In the manufacturing and assembly process of traditional generators, fixing the rotor assembly onto the shaft is a critical and highly demanding process.

[0003] Traditional rotor assembly installation uses an interference fit, requiring the inner bore of the rotor assembly to be press-fitted to the designed position on the shaft under immense pressure. This process necessitates specialized equipment such as presses, making operation extremely inconvenient. Furthermore, an interference fit is an irreversible, permanent connection; if misalignment or angular deviation is discovered after press-fitting, the entire rotor assembly and shaft may be rendered unusable, resulting in high costs and difficulty in guaranteeing yield. Therefore, there is an urgent need for a generator rotor assembly that is easy to install. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a generator rotor assembly that is easy to install.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easy-to-install generator rotor assembly includes a rotor assembly that is sleeved on a rotating shaft. Mounting slots are provided on both sides of the rotating shaft, and mounting components are fitted onto the rotor assembly corresponding to each mounting slot. Fixing seats are provided on both sides of the rotor assembly above the mounting components. Each fixing seat has a retaining cavity, and movable retaining components are fitted onto the rotating shaft corresponding to each retaining cavity. Screws for locking the retaining components are inserted into both sides of the fixing seats.

[0007] Furthermore, in a preferred configuration, spring cavities are provided on both sides of the rotating shaft within the mounting groove, and springs are installed outward within each spring cavity.

[0008] Furthermore, in a preferred configuration, the other end of each spring is connected to a locking element, and each locking element is provided with a wedge-shaped slope.

[0009] In addition, a preferred structure is that each of the spring cavities is fixedly provided with a guide member, and each of the clips is adapted to have a guide cavity corresponding to the guide member.

[0010] Furthermore, in a preferred configuration, through holes are provided on both sides of the fixing base, and screws are adapted to pass through the through holes.

[0011] In addition, a preferred structure is that both sides of the card have screw grooves, and the screw grooves are adapted to screws.

[0012] The beneficial effects of this utility model are as follows: the structure of automatically inserting the clamp into the clamp cavity by pushing the spring can realize the quick alignment and initial fixation of the rotor assembly and the rotating shaft. In addition, the locking method of screws and screw grooves realizes the reliability and disassembly of the connection, which is convenient for later maintenance and adjustment. It effectively solves the problems of irreversibility, high scrap rate and cumbersome operation of traditional interference fit. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-7A generator rotor assembly for easy installation includes a rotor assembly 1, which is mounted on a rotating shaft 2. Mounting slots 21 are provided on both sides of the rotating shaft 2, and mounting parts 11 are fitted onto the rotor assembly 1 corresponding to the mounting slots 21. Fixing seats 3 are provided on both sides of the rotor assembly 1 above the mounting parts 11. Each fixing seat 3 has a retaining cavity 31, and movable retaining parts 5 are fitted onto the rotating shaft 2 corresponding to the retaining cavity 31. Screws 4 for locking the retaining parts 5 are inserted into both sides of the fixing seats 3.

[0023] Both sides of the rotating shaft 2 are provided with spring cavities 22 within the mounting grooves 21, and springs 221 are installed outwardly within each spring cavity 22. The elastic force of the springs 221 allows the locking piece 5 to be stably pushed into the locking cavity 31. It is worth noting that the springs 221 are high-strength anti-vibration springs in the prior art, ensuring sufficient preload even under extreme vibration conditions. This is prior art and will not be elaborated further.

[0024] The other end of each spring 221 is connected to a retainer 5, and each retainer 5 is provided with a wedge-shaped slope 51. By providing the wedge-shaped slope 51, the rotor assembly 1 can first contact the wedge-shaped slope 51 during installation, so as to push the retainer 5 into the spring cavity 22.

[0025] Each spring cavity 22 is fixedly equipped with a guide member 23, and each clamping member 5 is provided with a corresponding guide cavity 53. The adaptation between the guide member 23 and the guide cavity 53 can improve the stability of the clamping member 5 during movement.

[0026] The fixing base 3 has through holes 32 on both sides, and the screws 4 are adapted to pass through the through holes 32. The clamping member 5 has threaded grooves 52 on both sides, and the threaded grooves 52 are adapted to the screws 4. The clamping member 5 can be fixed by the engagement between the screws 4 and the threaded grooves 52. It is worth noting that a threaded self-locking mechanism, which is common in the prior art, is provided between the screws 4 and the threaded grooves 52 to ensure that they can be firmly engaged.

[0027] In this embodiment, when the user needs to assemble the rotor assembly 1 onto the rotating shaft 2, he only needs to align the mounting part 11 on the rotor assembly 1 with the mounting groove 21 on the rotating shaft 2, and then directly put the rotor assembly 1 onto the rotating shaft 2.

[0028] During the downward movement of the rotating shaft assembly 1, the bottom of the rotating shaft assembly 1 will contact the wedge-shaped slope 51 on the clamp 5, so that by pushing the wedge-shaped slope 51, the clamp 5 will be pushed into the spring cavity 22, and at this time the spring 221 will be compressed.

[0029] When the mounting component 11 moves to the bottom of the mounting groove 21, the locking component 5 and the locking cavity 31 are aligned. At this time, the locking component 5 can automatically return to the locking cavity 31 by the elastic force of the spring 221. Then, the screw groove 52 on the locking component 5 is aligned with the through hole 32 on the fixing base 3. Finally, the user only needs to pass the screw 4 through the through hole 32 and insert it into the screw groove 52.

[0030] Furthermore, when the rotor assembly 1 and the shaft 2 rotate, the clamping piece 5 will move outward due to the centrifugal force generated by the rotation. At this time, the clamping piece 5 can be more stably clamped in the clamping cavity 31, thereby further improving the installation stability of the rotor assembly 1.

[0031] In this utility model, the structure of the spring 221 pushing the card 5 to automatically engage into the card cavity 31 can realize the rapid alignment and initial fixation of the rotor assembly 1 and the rotating shaft 2. Combined with the locking method of the screw 4 and the screw groove 52, the reliability and disassembly of the connection are realized, which facilitates later maintenance and adjustment. It effectively solves the problems of irreversibility, high scrap rate and cumbersome operation of traditional interference fit.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
