Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a hollow spindle axial flux motor for textile machinery. Background Art

[0002] In the textile industry, the transmission system of yarn equipment is crucial to improving production efficiency and ensuring product quality. Traditional motors usually adopt a solid shaft design and require additional matching components to pull and transmit the yarn. This method requires more transitional transfer components, making the structure and wiring of the entire equipment more complicated, which is not conducive to assembly and also makes subsequent maintenance more difficult. The stability of the equipment during operation is also reduced. Therefore, it is necessary to improve and simplify the yarn pulling method. In addition, traditional motors are usually large in size, low in efficiency, and noisy during operation, affecting the working environment. With the continuous development of textile technology, the performance requirements for motors are also getting higher and higher. A high-efficiency, compact, and low-noise motor is needed to meet the needs of textile machinery. Utility Model Content

[0003] To solve the above technical problems, the present invention relates to a hollow spindle axial flux motor for textile machinery. The motor has a simple and reliable structure, effectively solves the above technical problems, and is suitable for popularization and use. To achieve the above purpose, the present invention is implemented through the following technical solutions:

[0004] A hollow spindle axial flux motor for textile machinery comprises a motor main shaft and a split housing, wherein the motor main shaft passes through the inner hole of the split housing, and a stator assembly and a rotor arranged opposite to each other are installed inside the split housing, wherein the stator assembly comprises a stator core and a winding, wherein a plurality of stator cores are evenly spaced around the circumferential direction, and a winding is arranged on the outside of each stator core, and the rotor comprises a plurality of fan-shaped permanent magnets, wherein the plurality of permanent magnets are evenly spaced around the circumferential direction and are arranged opposite to the stator core in the upper and lower directions, and the motor main shaft is made of alloy steel and is provided with a central through hole extending through the motor main shaft along the axial direction, and a cylindrical connecting sleeve is provided at the bottom of the base of the split housing, and an externally threaded connecting section is provided on the outer peripheral surface of the cylindrical connecting sleeve.

[0005] On the basis of the above scheme and as a preferred scheme of the above scheme: the split casing also includes an end cover, a support tube, and a base. The end cover is arranged on the top of the support tube and is screwed together through threads. The support tube and the base are provided with three corresponding bolt connection holes that are evenly spaced around the circumference. The support tube and the base are detachably connected by a bolt assembly.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: it also includes a limit sleeve, the inner wall of the base is provided with an internal thread, the limit sleeve is installed in the inner cavity of the base, the limit sleeve is provided with an external thread that cooperates with the internal thread of the lower shell of the motor, and the limit sleeve is connected to the base by a threaded connection.

[0007] On the basis of the above solution and as a preferred solution of the above solution: an installation cavity is formed between the limiting sleeve and the inner hole of the base, and a shock-absorbing sleeve is installed in the installation cavity.

[0008] On the basis of the above solution and as a preferred solution of the above solution: an upper bearing and a lower bearing are further provided in the installation cavity, and the upper bearing and the lower bearing are rotatably matched with the motor main shaft.

[0009] On the basis of the above solution and as a preferred solution of the above solution: the section of the motor main shaft above the motor upper shell is a conical structure that is smaller at the top and larger at the bottom.

[0010] Compared with the existing technology, the present invention has the following outstanding and beneficial technical effects: the hollow design of the motor main shaft allows the yarn to pass directly through, and there is no need for a transfer transition component, which simplifies the structure of the yarn traction device, reduces the number of components, reduces the complexity of the overall equipment, and optimizes the layout of the entire spinning machine. The motor casing can be quickly disassembled and assembled, which improves the connection stability and facilitates maintenance and upgrading. The shock-absorbing sleeve effectively isolates vibration, protects internal components, and extends the life of the equipment.

This design allows the motor to be quickly locked and installed by matching nuts during installation.

[0011] The stator and rotor of the axial flux motor are arranged along the same axial direction. This layout makes the motor smaller and lighter, making it easier to integrate into space-constrained applications. The axial flux motor has a shorter magnetic flux path, which helps reduce energy loss and improve the efficiency of the motor. The axial flux motor has a uniform magnetic field distribution and generates less noise and vibration during operation. Due to the advantages of size and weight, the axial flux motor uses less copper, iron, and permanent magnet materials in the production and manufacturing process than the radial permanent magnet motor, which helps to achieve energy conservation and carbon reduction. The design of the axial flux motor is conducive to heat dissipation because heat can be more easily dissipated through the axial direction of the motor, which helps to maintain stable operation of the motor under high load.

[0018] In order to solve the above technical problems, Figure 1-3 As shown, the utility model designs a hollow spindle axial flux motor for textile machinery, including a motor main shaft 1 and a split housing 2. The motor main shaft 1 passes through the inner hole of the split housing 2. The interior of the split housing 2 is equipped with a stator assembly 3 and a rotor 4 that are arranged opposite to each other inside and outside. The stator assembly includes a stator core 31 and a winding 32. A plurality of stator cores 31 are evenly spaced around the circumferential direction. A winding 32 is provided on the outside of each stator core 31. The rotor 4 includes a plurality of fan-shaped permanent magnets. The rotor is fixedly matched with the motor main shaft and can rotate with it, and the permanent magnets rotate with it. The plurality of permanent magnets are evenly spaced around the circumferential direction and are arranged opposite to the stator core 31 up and down. The motor shaft is made of alloy steel, and the stator and rotor of the axial flux motor are arranged along the same axial direction. This layout makes the motor smaller and lighter, and is easy to integrate into space-constrained applications. The axial flux motor has a shorter magnetic flux path, which helps to reduce energy loss and improve the efficiency of the motor. The magnetic field of the axial flux motor is evenly distributed, and the noise and vibration generated during operation are low. Due to the advantages of volume and weight, the axial flux motor uses less copper, iron, and permanent magnet materials in the production and manufacturing process than the radial permanent magnet motor, which helps to achieve energy saving and carbon reduction. The design of the axial flux motor is conducive to heat dissipation because heat can be more easily dissipated through the axial direction of the motor, which helps to maintain stable operation of the motor under high load.

[0019] The motor main shaft 1 is provided with a central through hole extending along the axial direction. The tail end of the motor main shaft 1 is used to connect the traction head. The hollow design allows the yarn to pass directly through for traction transmission, eliminating the need for traditional transfer components, simplifying the structure of the spinning machine, reducing the number of components, reducing the complexity and weight of the equipment, and facilitating maintenance.

[0020] A cylindrical connecting sleeve 5 is provided at the bottom of the base 23 of the split housing 2, and an external threaded connecting section is provided on the outer peripheral surface of the cylindrical connecting sleeve 5. This design allows the motor to be quickly locked by matching nuts during installation. The use of external threads and nuts can ensure that the motor has higher 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.

[0021] It is further preferred in this embodiment that the split casing 2 also includes an end cover 21, a support tube 22, and a base 23. The end cover 21 is provided on the top of the support tube 22 and is screwed together by threads. The support tube 22 and the base 23 are provided with three corresponding bolt connection holes that are evenly spaced around the circumference. The support tube 22 and the base 23 are detachably connected by a bolt assembly. The bottom of the support tube is also provided with a supporting portion for supporting the stator assembly, so as to achieve a fixed support effect. The modular structure combination facilitates manufacturing and assembly, simplifies the assembly process, and the detachable connection of the bolt assembly makes the assembly and disassembly of the casing more convenient, and facilitates maintenance and replacement of parts. The bolt connection hole achieves a firm connection between the support tube and the base, thereby enhancing the stability of the overall structure.

[0022] It is further preferred in this embodiment that a limit sleeve 7 is further included, the inner wall of the base 23 is provided with an internal thread, the limit sleeve 7 is installed in the inner cavity of the base 23, the limit sleeve 7 is provided with an external thread that cooperates with the internal thread of the lower shell of the motor, the limit sleeve 7 is connected to the base 23 by a threaded connection, and an installation cavity is formed between the limit sleeve 7 and the inner hole of the base 23, and a shock-absorbing sleeve 6 is installed in the installation cavity, which provides a reliable positioning mechanism for the limit sleeve 7 to ensure the precise position of the internal components of the motor during operation and prevent displacement. The setting of the shock-absorbing sleeve 6 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 life of the equipment.

[0023] It is further preferred in this embodiment that an upper bearing 8 and a lower bearing 9 are also provided in the mounting cavity. The upper bearing 8 and the lower bearing 9 rotate with the motor main shaft 1 to provide low-friction support, ensure the smooth operation of the motor main shaft 1, reduce energy loss, and enhance support for the motor main shaft 1 at this position.

[0024] It is further preferred in this embodiment that the motor main shaft 1 has a conical structure with a small top and a large bottom above the motor upper shell. The torsional shear stress borne by the root of the shaft neck of the conical structure 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.
