Description

Technical Field

[0001] This utility model relates to the field of rotor lamination technology, and in particular to a motor rotor lamination structure. Background Technology

[0002] The primary function of rotor laminations is to control friction and wear that occur during rotor operation. When the rotor rotates, the small gap between the rotor and stator leads to significant friction, causing energy loss, overheating of the motor, and wear of mechanical components. The role of rotor laminations is to adjust the rotor's position within a small range through the friction between static and dynamic rings, ensuring normal motor operation.

[0003] As an indispensable component in a motor, rotor laminations need to be bound with multiple metal wires for fixation during use. Due to the limited length of the metal wires and insufficient openings in the rotor laminations, the wires are prone to knotting and mis-binding during the binding process, which leads to a decrease in rotor lamination stability.

[0004] To address this, we designed a motor rotor lamination structure. Utility Model Content

[0005] The purpose of this invention is to propose a motor rotor lamination structure to solve the problem of low stability in existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A motor rotor lamination structure includes a disc body with holes and multiple threads for connecting the motor rotor.

[0008] The disc body has multiple winding holes for winding metal wires, multiple first inserts, and multiple adapter slots.

[0009] Preferably, the winding hole is annularly formed on the side wall of the disc body, and the winding hole is rectangular. The winding hole is provided with a rubber sleeve for protecting the metal wire.

[0010] Preferably, the disc body is provided with a plurality of first connecting rods, and the first connecting rods are fixedly connected to the disc body, and the first connecting rods are provided with a plurality of through holes.

[0011] Preferably, the through hole penetrates the disk body, and the disk body is provided with a plurality of flat fan-shaped parts, which are arranged in a ring on the disk body.

[0012] Preferably, the first insert is fixedly connected to the flat fan body, and the hole is provided with a second insert.

[0013] Preferably, the hole is provided with a plurality of first flow holes for improving air circulation, one end of the flat fan body is fixedly connected to the inner wall of the disk body through a second connecting rod, the disk body is provided with a plurality of second flow holes, and the adapter groove is provided on the flat fan body.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the setting of winding holes and rubber sleeves, allows the winding efficiency of metal wires to be improved by the large number of winding holes after the disc is installed on the motor rotor. At the same time, the metal wires can be reduced from loosening during long-term operation of the motor rotor by being restricted by multiple winding holes. The rubber sleeve can improve the protection effect of the metal wires in the winding holes and also achieve the effect of restricting the metal wires, thereby improving the stability of the rotor laminations.

[0016] 2. By setting the first flow hole and the second flow hole, this utility model can increase the air circulation efficiency of the disc body during motor operation after it is installed on the rotor, thereby further improving the efficiency of the disc body and effectively improving the overall lightness of the disc body.

[0022] Reference Figures 1-4 A motor rotor lamination structure includes a disc body 1, which is made entirely of aluminum material, the same material used for manufacturing motor rotor laminations in the prior art. The hole 2 is an opening made in the middle section of the motor rotor lamination in the prior art, used to connect the rotor's central shaft. Its overall lightweight design can effectively improve operating efficiency, and the thread can improve the connection strength between the disc body 1 and the rotor's central shaft.

[0023] The disc body 1 has multiple winding holes 3 for winding metal wires. The winding holes 3 are mainly used to improve the winding effect of the metal wires on the motor rotor and avoid affecting the stability of the rotor laminations during motor operation. The winding holes 3 are arranged in a ring on the side wall of the disc body 1. The ring arrangement of the winding holes 3 can effectively improve the winding effect and flexibility of the metal wires. The winding holes 3 are rectangular, which makes it easier to hook and fix the metal wires. The winding holes 3 are equipped with rubber sleeves to protect the metal wires. The rubber sleeves are set inside the winding holes 3 and are mainly used to protect the metal wires inside the winding holes 3, while reducing the metal wires from coming off the winding holes 3 due to pulling.

[0024] The disc body 1 is provided with multiple first connecting rods 4. The first connecting rods 4 are used to improve the overall strength of the disc body 1. The first connecting rods 4 are fixedly connected to the disc body 1. Welding is an existing technology. While improving the connection strength, it also increases the overall stability of the disc body 1. Multiple through holes 5 are provided on the first connecting rods 4. The through holes 5 are used to improve the airflow effect, thereby reducing the wind resistance of the disc body 1.

[0025] The through hole 5 penetrates the disc body 1 completely, which can improve the stability of the disc body 1 on the rotor. The disc body 1 is provided with multiple flat fan bodies 6. The flat fan bodies 6 are used to increase the arrangement space of the disc body 1, and other components that are beneficial to the rotor laminations can be added later. At the same time, equipment for measuring the working stability of the rotor laminations can also be installed. The flat fan bodies 6 are arranged in a ring on the disc body 1. There are a total of six flat fan bodies 6, which are arranged along the outer ring of the hole 2, which can effectively improve the overall stability and strength of the disc body 1.

[0026] The disc body 1 is provided with multiple first embeddings 7. The first embeddings 7 are used to enhance the three-dimensional effect of the flat fan body 6, so that the position of the disc body 1 can be identified immediately during manual inspection, thereby improving the recognition. The first embeddings 7 are fixedly connected to the flat fan body 6. The first embeddings 7 are made of stainless steel, and welding can improve the connection strength between the two, further improving the stability of the first embeddings 7 on the flat fan body 6. The hole 2 is provided with a second embedding 8. The second embedding 8 is set along the outer wall of the hole 2, which can effectively improve the rugged effect around the hole 2 and the recognition effect.

[0027] The disc body 1 has multiple adapter slots 11, which are used for later installation of measuring equipment and components. They need to be fixed by adapter fasteners. The hole 2 has multiple first flow holes 9 to improve airflow. The first flow holes 9 are used to improve the airflow effect when the motor rotor is running, thereby reducing the overall wind resistance of the disc body 1. One end of the flat fan body 6 is fixedly connected to the inner wall of the disc body 1 through the second connecting rod 10. The second connecting rod 10 is an auxiliary connecting component, which can effectively improve the strength and stability of the connection between the flat fan body 6 and the outer wall of the hole 2. The disc body 1 has multiple second flow holes 12, which are opened on the outer extension of the flat fan body 6, that is, on the surface of the disc body 1, to reduce the wind resistance around the flat fan body 6.

[0028] The working principle of this utility model is as follows:

[0029] Place the disc 1 in a suitable position, ensuring its stability and ease of operation. Secure the disc 1 to the central shaft of the motor rotor using screws or welding, ensuring a firm and reliable connection. Select appropriate metal wire according to the motor's design requirements, and thread the wire sequentially through the winding holes 3 on the disc 1. Use rubber sleeves to protect the wire and prevent it from coming loose due to pulling. Ensure the metal wire is evenly and tightly wound on the disc 1 to improve the motor rotor's performance. Weld the first connecting rod 4 to the disc 1 to increase its overall strength and stability, ensuring the through hole 5 on the first connecting rod 4 aligns with the corresponding opening on the disc 1. To facilitate airflow, the flat fan body 6 is fixed to the inner wall of the disk body 1 via the second connecting rod 10, ensuring a secure connection. The flat fan body 6 helps increase the arrangement space of the disk body 1, making it easier to install other components or measuring equipment later. The first embedding body 7 is welded to the flat fan body 6 to enhance its three-dimensional effect and recognizability. The second embedding body 8 is installed in the hole 2 to improve the rugged effect and recognition effect around the hole 2. As needed, measuring equipment or other components are installed in the adapter groove 11 and fixed using adapter fasteners to ensure that the first flow hole 9 and the second flow hole 12 are unobstructed, so as to facilitate airflow and reduce wind resistance.

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.
