In addition, the existing motor casing is usually an integrated structure with an inconvenient internal structure assembly. The installation method of the casing is also complicated and inconvenient, affecting the installation efficiency. Utility Model Content

[0015] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0016] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate directions or positional relationships based on the attached Figure 1The directions or positional relationships shown are only for the convenience of describing the present invention, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0017] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0018] In order to solve the above technical problems, Figure 1-3 As shown, the utility model designs a hollow conduction motor, including a motor spindle 1, a motor upper shell 2, and a motor lower shell 3. The motor upper shell 2 and the motor lower shell 3 are detachably connected, and the motor spindle 1 passes through the through holes of the motor upper shell 2 and the motor lower shell 3. Specifically, the outer periphery of the motor upper shell 2 is provided with a plurality of first radial protrusions 4 evenly spaced along the circumferential direction, and the motor lower shell 3 is provided with second radial protrusions 5 corresponding to the first radial protrusions 4 one by one, and corresponding bolt connection holes are provided between the first radial protrusions 4 and the second radial protrusions 5. The first radial protrusions 4 and the second radial protrusions 5 are connected by a bolt assembly, which provides a method for rapid disassembly and assembly and precise alignment, enhances the connection stability of the motor housing, can realize rapid disassembly and assembly of the motor housing, improves the connection stability, and is convenient for maintenance and upgrading.

[0019] A stator assembly 6 is installed on the inner side of the motor upper shell 2, and the motor main shaft 1 is connected to a rotor assembly 7 corresponding to the stator assembly 6. The rotor assembly 7 includes and preferably adopts a magnetic ring rotor. The design of the magnetic ring rotor improves the magnetic field efficiency and energy efficiency ratio of the motor, so that the motor has a stronger output power and higher efficiency at the same size and weight.

[0020] The motor main shaft 1 is provided with a central through hole 8 penetrating along the axial direction. The hollow design of the motor main shaft 1 allows the yarn to pass directly through for traction transmission, eliminating the need for traditional transfer transition components, simplifying the structure of the spinning machine, reducing the number of components, reducing the complexity and weight of the equipment, and facilitating maintenance.

[0021] A cylindrical connecting sleeve 9 is provided at the bottom of the motor lower shell 3, and an external threaded connecting sleeve 9 is provided on the outer peripheral surface thereof. This design allows the motor to be quickly tightened by matching nuts during installation. The combination of external threads and nuts can ensure that the motor has high stability after installation and reduce displacement caused by vibration or external force. When the motor needs to be maintained or replaced, the external threaded connection design makes the disassembly process simpler and faster.

[0022] If the motor spindle 1 is used to directly pull the yarn, it is necessary to consider the impact force generated by the yarn when it rotates at high speed or stops suddenly. The lack of a shock-absorbing mechanism may cause the yarn to break or the motor spindle 1 to be damaged, affecting production efficiency and equipment life. Furthermore, it also includes a limit sleeve 11, and the inner wall of the motor lower shell 3 is provided with an internal thread. The limit sleeve 11 is installed in the inner cavity of the motor lower shell 3, and the limit sleeve 11 is provided with an external thread that cooperates with the internal thread of the motor lower shell 3. The limit sleeve 11 is connected to the motor lower shell 3 by a threaded connection. An installation cavity is formed between the limit sleeve 11 and the inner hole of the motor lower shell 3, and a shock-absorbing sleeve 12 is installed in the installation cavity. The threaded connection between the limit sleeve 11 and the motor lower shell 3 provides a reliable positioning mechanism to ensure the precise position of the internal components of the motor during operation and prevent displacement. The setting of the shock-absorbing sleeve 12 in the installation cavity can effectively absorb and isolate the vibration generated by the operation of the motor, reduce the impact on the motor performance, and extend the equipment life.

[0023] Furthermore, an upper bearing 13 and a lower bearing 14 are also provided in the installation cavity, and the upper bearing 13 and the lower bearing 14 are rotatably matched with the motor main shaft 1. The setting of the upper bearing 13 and the lower bearing 14 and the rotatable match with the motor main shaft 1 provide low-friction support, ensure the smooth operation of the motor main shaft 1, reduce energy loss, and enhance the support for the motor main shaft 1 at this position.

[0024] Furthermore, the motor main shaft 1 has a conical structure above the motor upper shell 2, which is smaller at the top and larger at the bottom. The torsional shear stress borne by the shaft root of the conical main shaft is greater than that of a straight shaft, and it is not easy to break the shaft due to metal fatigue caused by alternating stress.

[0025] It is worth noting that the technical features such as the shock-absorbing sleeve, stator, rotor, bolt connection, etc. involved in this utility model patent application should be regarded as the prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and should not be regarded as the invention point of this utility model patent. This utility model patent will not be further elaborated.

[0026] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made by technicians in the relevant technical field based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
