Description

Technical Field

[0001] This utility model relates to the field of motor rotor technology, and in particular to a motor rotor that can be assembled with high precision. Background Technology

[0002] The motor rotor is a key component of an electric motor. Its main function is to generate rotational torque through electromagnetic induction, thereby driving the motor's rotation. Motor rotors are widely used in various electrical devices, such as industrial motors, household appliances, and electric vehicles. The rotor's performance directly affects the motor's efficiency, stability, and lifespan. Traditional motor rotors typically consist of a rotor shaft, rotor core, and windings. During assembly, these components are secured together using bolts, clips, or other mechanical connections. The windings are usually wound manually or semi-automatically onto the rotor core and then protected with insulating material.

[0003] Traditional motor rotor windings are typically protected by simple insulation materials, lacking effective protective measures. They are easily damaged during assembly and operation. Furthermore, the casing design of traditional motor rotors is not reasonable enough, lacking anti-slip and protective functions, which can easily cause operators to slip or get injured during assembly and maintenance. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a motor rotor that can be assembled with high precision.

[0005] This utility model is achieved by the following technical solution: a motor rotor that can be assembled with high precision, including an upper mounting shell, a winding frame installed on the inner wall of the upper mounting shell, an upper protective pad fixedly connected to the top of the winding frame, a lower protective pad fixedly connected to the bottom of the winding frame, an enameled wire sleeved on the surface of the winding frame, and a limit groove opened at the bottom of the lower protective pad, the inner wall of the limit groove engaging with the surface of the enameled wire.

[0006] Through the above technical solution, the upper protective pad at the top of the winding frame provides protection to prevent mechanical damage to the enameled wire during assembly and operation, ensuring the integrity of the winding, providing insulation, preventing short circuits between the enameled wire and the winding frame, and improving the safety and reliability of the motor. The lower protective pad at the bottom of the winding frame provides protection to prevent mechanical damage to the enameled wire during assembly and operation, ensuring the integrity of the winding. The limiting groove fixes the end of the enameled wire, ensuring that the winding will not shift during operation, improving assembly accuracy and operational stability. The limiting groove, by engaging the surface of the enameled wire, ensures that the enameled wire is accurately fixed on the winding frame, preventing the enameled wire from shifting during operation, improving the stability and reliability of the winding, and ensuring the precise alignment of the end of the enameled wire during assembly, improving assembly efficiency and accuracy.

[0007] As a further improvement to the above solution, a motor rotor body is installed on the inner wall of the upper mounting shell, the surface of the motor rotor body is provided with external threads, and the top of the motor rotor body is provided with an assembly port.

[0008] Through the above technical solution, the external thread, in conjunction with the thread inside the upper mounting housing, fixes the motor rotor body inside the upper mounting housing, ensuring the stability and reliability of the assembly. The thread engagement ensures the precise alignment of the motor rotor body during the assembly process, improving assembly accuracy. The assembly port provides an interface for inserting and operating assembly tools, facilitating the connection between the winding frame and the motor rotor body, and improving assembly efficiency.

[0009] As a further improvement to the above solution, the top of the upper mounting shell is provided with two connecting bolts, which are connected to the inside of the lower mounting shell via threads.

[0010] Through the above technical solution, the connecting bolts securely fix the upper and lower mounting shells together by threaded connection with the upper and lower mounting shells, ensuring the stability of the overall structure. The tightening action of the connecting bolts ensures the precise alignment of the upper and lower mounting shells during the assembly process, improving assembly accuracy.

[0011] As a further improvement to the above solution, a protective sleeve is fixedly connected to the surface of the upper mounting shell, and the surface of the protective sleeve is fixedly connected with anti-slip patterns, and a plurality of anti-slip patterns are provided.

[0012] Through the above technical solutions, the protective sleeve protects the upper mounting shell from external mechanical damage and environmental influences, extending the service life of the rotor. The anti-slip texture provides an anti-slip function, preventing operators from slipping during assembly and maintenance, ensuring operational safety. By increasing friction, damage to the upper mounting shell during operation is reduced, extending the service life of the equipment.

[0013] As a further improvement to the above solution, a rotor shaft is fixedly connected to the bottom end of the motor rotor body, and a balance block is fixedly connected to the surface of the rotor shaft, with the top end of the balance block contacting the bottom end of the lower mounting shell.

[0014] The above technical solution ensures the rotor's balance during operation by adjusting the position of the balance block, reducing vibration and improving the motor's smoothness and reliability. The top of the balance block contacts the bottom of the lower mounting housing, providing stable support and ensuring the balance block's stability during operation.

[0015] As a further improvement to the above solution, the bottom end of the lower mounting shell is provided with positioning holes. There are two positioning holes, and the two ends of the enameled wire are fixedly connected to the surface of the rotor shaft through the two positioning holes.

[0016] Through the above technical solution, the positioning hole, by cooperating with the end of the enameled wire, fixes the enameled wire to the surface of the rotor shaft, ensuring the stability of the enameled wire during operation, improving assembly accuracy, ensuring the precise alignment of the end of the enameled wire during assembly, and improving assembly efficiency and accuracy.
