Description

Technical Field

[0001] The utility model relates to the field of motor rotor shafts, and particularly relates to a novel motor rotor shaft. Background Art

[0002] The motor rotor shaft, as an indispensable core component of the motor, is of self-evident importance. It is not only the cornerstone for supporting and driving the rotating components, but also responsible for transmitting torque to ensure the precise positioning between the rotating components and the stator, thereby efficiently realizing the conversion of mechanical and electrical energy. The design and manufacturing quality of the rotor shaft are directly related to the overall performance and operation reliability of the motor. With the rapid development of technology, the design and manufacturing processes of the rotor shaft are also continuously improving, striving to ensure the safe operation of the motor while improving efficiency.

[0003] However, while undertaking key tasks, the motor rotor shaft also faces severe challenges. Under long-term high-speed rotation and heavy-load working conditions, the continuous friction between the rotor shaft and the bearing is extremely likely to cause wear at the journal part. This wear may be caused by various factors such as insufficient lubrication systems, aging and failure of grease, improper adjustment of bearing clearances, or pollution of the external environment.

[0004] When the motor rotor shaft needs to be repaired or replaced, its disassembly process is often complex and full of challenges. First of all, the rotor shaft is closely connected to multiple precision components such as bearings, couplings, and gears. The disassembly and installation of these components require extremely high precision and professionalism. Secondly, the limitations of the motor installation environment, such as small space or obstruction by surrounding equipment, may make the disassembly work even more difficult. Especially for large motors, the weight and volume of their rotor shafts pose extremely strict requirements for the disassembly work, and professional lifting equipment and teamwork must be relied on to ensure safety.

[0005] In addition, any negligence or improper operation during the disassembly process may cause irreversible damage to the rotor shaft or other components, thereby increasing the maintenance cost and bringing potential safety risks. More troublesome is that due to the difficulty of disassembly, the regular inspection and maintenance of the rotor shaft have become extremely difficult, which may lead to wear problems being difficult to detect and handle in a timely manner, thereby threatening the long-term stable operation of the motor. Summary of the Utility Model

[0006] The main purpose of the utility model is to provide a novel motor rotor shaft, which can effectively solve the problems put forward in the background art.

[0007] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A new type of motor rotor shaft includes a main shaft and a rotor winding. Embedding holes and docking hole positions are respectively provided at both ends of the main shaft, and modular motor rotors are installed at the embedding holes and docking hole positions of the main shaft. Through the modular motor rotors, rapid disassembly and assembly are achieved, and later maintenance is facilitated. A cavity is formed inside the modular motor rotor, and a rotor winding is installed at the cavity;

[0009] The modular motor rotor includes a rotor arc part and a rotor connection part. The rotor connection part is located on the inner arc surface of the rotor arc part, and an installation block is provided at one end of the rotor connection part. An installation hole position adapted to the docking hole position is provided on the installation block, and an embedding block adapted to the embedding hole is provided at the lower part of the other end of the rotor connection part. Bolts are inserted into the installation hole position and the docking hole position to fix the modular motor rotor to the main shaft.

[0010] As a further preferred scheme of the utility model, the rotor arc part and the rotor connection part are integrally designed, and the cross-section of the rotor arc part and the rotor connection part is designed in an "I" shape, and the inner and outer ends of the rotor arc part and the rotor connection part are both arc surfaces;

[0011] As a further preferred scheme of the utility model, the inner arc surface of the rotor connection part is closely attached to the main shaft, and a plurality of rotor connection parts are annularly distributed on the main shaft, and a cavity is provided between adjacent rotor connection parts;

[0012] As a further preferred scheme of the utility model, the installation block is integrally designed with the rotor connection part, the cross-section of the installation block is designed in a "C" shape, and a rubber gasket is provided on the inner arc surface of the installation block. A rubber strip is provided between adjacent installation blocks and rotor connection parts, and adjacent rotor connection parts are butt-jointed seamlessly;

[0013] As a further preferred scheme of the utility model, the installation hole position and the docking hole position are screw holes, the embedding hole is an "L"-shaped hole, and the cross-section of the embedding block is designed in an "L" shape to stabilize the other end of the rotor connection part through the embedding block;

[0014] As a further preferred scheme of the utility model, a rubber gasket is provided at the connection between the embedding block and the embedding hole to prevent the embedding block from shifting after being stabilized.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the utility model, the modular design enables the motor rotor to be disassembled and installed quickly and conveniently, greatly reducing the time required for maintenance and replacement. Due to the modularization of the rotor assembly, the maintenance work becomes simpler, it is easy to check and replace faulty components, and the maintenance cost is reduced.

[0017] The integrated design of the rotor arc part and the rotor connection part, as well as the "I"-shaped cross-sectional structure, improve the overall strength and stability of the rotor. The modular motor rotor uses the cavity to place the rotor winding, achieving the compactness of the structure, which helps to reduce the volume of the motor and improve the space utilization rate.

[0018] The overall structural design takes durability into account, reduces the maintenance frequency caused by wear or damage, and extends the service life of the motor. After installation, the modular design makes the commissioning and debugging process of the motor more convenient, which helps to quickly optimize the motor performance to the best state.

Detailed Description of the Preferred Embodiments

[0024] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] As Figure 1 - Figure 4 shown, an innovative design of the motor rotor shaft structure is introduced, and its core components include the main shaft 1 and the built-in rotor winding 4. The main shaft 1 has a unique structure, and the embedding holes 26 and the docking hole positions 25 are carefully designed at both ends, which are the key parts for installing the modular motor rotor 2. The introduction of the modular motor rotor 2 greatly improves the disassembly and assembly efficiency of the equipment and the convenience of later maintenance.

[0026] The structure of the modular motor rotor 2 is also exquisite. It consists of two major parts: the rotor arc part 21 and the rotor connection part 22. The two adopt an integrated design, and the cross section presents a stable "I" shape, which not only enhances the structural strength, but also ensures a smooth transition between the inner and outer ends. The rotor connection part 22 is cleverly fitted on the main shaft 1. Multiple such parts are evenly distributed around the main shaft 1. A cavity 3 is cleverly opened between them for accommodating the rotor winding 4, thereby achieving a compact structure and functional integration.

[0027] In order to achieve a stable connection between the modular motor rotor 2 and the main shaft 1, the designer cleverly sets a mounting block 23 at one end of the rotor connection part 22. The cross section of the mounting block 23 presents a "C" shape, which not only enhances the integrity with the rotor connection part 22, but also has a rubber gasket installed on its inner arc surface to increase the sealing and stability of the connection. At the same time, the mounting hole 24 opened on the mounting block 23 matches the docking hole 25 on the main shaft 1, and the tight connection between the two is achieved through the tightening action of the bolts.

[0028] The other end of the rotor connection part 22 is designed with an insert 27 that matches the insert hole 26. The insert hole 26 has a unique shape, which is an "L" shape. The corresponding cross section of the insert 27 is also designed to be "L" shaped. This design not only facilitates the accurate embedding of the insert 27, but also effectively prevents the rotor connection part 22 from shifting during operation by increasing the contact area and stability. In addition, a rubber gasket is added at the connection between the insert 27 and the insert hole 26 to further enhance the stability and shock resistance of the connection.

[0029] Rubber strips are cleverly arranged between adjacent mounting blocks 23 and rotor connecting parts 22. This design not only optimizes the connection effect between components, but also ensures seamless connection between adjacent rotor connecting parts 22, thereby achieving smooth transition and efficient operation of the overall structure.

[0030] The design of this new type of motor rotor shaft integrates multiple advanced concepts such as modularization, integration and precision. It not only improves the efficiency of equipment disassembly and assembly and the convenience of maintenance, but also enhances the overall stability and durability through a series of ingenious structural designs.

[0031] Disassembly process: Make sure the motor is powered off and in a safe state to prevent accidental startup. Prepare necessary tools, such as wrenches, screwdrivers, rubber hammers, etc. Use a wrench or screwdriver to remove the bolts connecting the mounting block 23 and the connecting hole 25 of the spindle 1 one by one. Pay attention to the preservation of the bolts to avoid loss or damage.

[0032] Gently tap the rotor connection part 22 to separate it from the insert block 27 in the insert hole 26 on the main shaft 1. Note not to apply excessive force to avoid damaging the rubber gasket or the insert block 27. After all the rotor connection parts 22 are separated from the main shaft 1, remove the modular motor rotor 2 as a whole from the main shaft 1. Note to keep the integrity of the rotor winding 4 and avoid damage during the removal process.

[0033] Clean the contact surfaces of the main shaft 1 and the modular motor rotor 2 to remove dirt and residues. Check whether each component is worn or damaged and replace it if necessary.

[0034] During installation: Ensure that all components have been cleaned and are in good condition. Prepare the necessary tools, such as wrenches, screwdrivers, rubber hammers, etc.

[0035] Align the insert block 27 on the rotor connection part 22 of the modular motor rotor 2 with the insert hole 26 on the main shaft 1. Gently tap the insert block 27 to accurately embed it into the insert hole 26 and ensure that the rubber gasket is in the correct position.

[0036] Align the mounting hole positions 24 on the mounting block 23 with the docking hole positions 25 on the main shaft 1. Use bolts and wrenches or screwdrivers to fasten the mounting block 23 to the main shaft 1. Ensure that all bolts have been evenly tightened to prevent loosening.

[0037] Check whether all the rotor connection parts 22 have been correctly installed and fastened. Ensure that the rotor winding 4 has been properly placed in the cavity 3 without being squeezed or damaged.

[0038] After confirming that all components have been installed, conduct a trial run of the motor. Observe whether the motor runs smoothly and whether there are any abnormal noises or vibrations. Conduct necessary debugging and optimization as needed to ensure that the motor performance reaches the best state.

[0039] It should be noted that in this article, relational terms such as first and second (No. 1, No. 2), etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
