Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to an air-cooled motor that is easy to assemble. Background Art

[0002] In today's society, motors are widely used. Traditional motor casings are mostly integral structures. When installing internal components such as stators and rotors, complex fixtures are often required, and the operating space is small, making the assembly process time-consuming and labor-intensive. Especially for some large motors or motors that require frequent maintenance and replacement of parts, this traditional structure seriously affects production efficiency and maintenance convenience.

[0003] Traditional motors have a relatively simple heat dissipation method, usually relying only on the natural heat dissipation of the casing. When running under high load or working continuously for a long time, the heat inside the motor is difficult to dissipate quickly, which can easily cause the motor temperature to rise too high, thus affecting the performance and service life of the motor.

[0004] In addition, the way the shaft and components of traditional motors match each other is relatively fixed. When the shaft system fails and needs to be repaired or replaced, the disassembly and installation process is cumbersome, which increases maintenance costs and downtime. Summary of the invention

[0019] The present invention provides an air-cooled motor that is easy to assemble and has the following beneficial effects:

[0020] 1. This air-cooled motor, which is easy to assemble, is assembled by setting the rotating shaft assembly, and the cross-shaped clamping strips at the ends of the output shaft and the terminal shaft are clamped and assembled with the cross-shaped clamping grooves at both ends of the middle shaft. Such a setting makes the assembly of the rotating shaft assembly more flexible and convenient. During the production process, each part can be processed and manufactured separately, and then quickly spliced, which improves production efficiency. At the same time, when a part of the shaft is damaged, it can be replaced separately, which reduces the maintenance cost, effectively prolongs the overall service life of the rotating shaft assembly, and improves the overall reliability and economy of the motor.

[0021] Second, the air-cooled motor that is easy to assemble is provided with a clamping structure between the fan assembly and the terminal shaft. During installation, the first clamping ring squeezes the first clamping strip to deform the arc spring. After the clamping ring is in place, the spring recovers to achieve clamping. This structure facilitates the installation and removal of the fan assembly on the rotating shaft. When the fan needs to be cleaned, replaced or repaired, the operation is simple and quick. In addition, the clamping structure can ensure the stability of the fan when rotating at high speed, ensure a good air cooling effect, enable the motor to effectively dissipate heat during operation, maintain a stable operating temperature, thereby improving the working efficiency of the motor and extending its service life.

[0022] 3. The air-cooled motor that is easy to assemble is provided with a stator assembly. When assembling, adjacent stator cores are clamped with the clamping blocks through the clamping grooves, and the V-shaped clamping blocks cooperate with the clamping grooves during axial splicing. This structure simplifies the assembly process of the stator assembly, does not require complicated welding or bolt connection processes, and reduces assembly time and labor costs. At the same time, the clamping structure ensures the tightness and stability of the connection between the stator cores, which is conducive to improving the uniformity and stability of the magnetic field generated by the stator assembly.

[0023] Fourth, the air-cooled motor which is easy to assemble is provided with a clamping assembly between the casing and the end casing, the second clamping ring of the first fixing ring is clamped with the clamping ring groove of the second fixing ring, and the positioning ring is clamped with the positioning ring groove and the second clamping strip is clamped with the second clamping groove. This design makes the connection between the casing and the end casing convenient and quick. When assembling or repairing the motor, the end casing can be quickly installed and disassembled, and the connection structure is stable and reliable, which can effectively prevent the end casing from loosening or displacement during the operation of the motor, and ensure the stability of the internal structure of the motor.

[0024] 5. The air-cooled motor which is easy to assemble has heat sinks of the stator assembly and strip-shaped through holes in the casing. The heat sinks on the outer surface of the stator core cooperate with the strip-shaped through holes on the surface of the casing. During the operation of the motor, heat is transferred from the stator core to the heat sink for heat exchange with the external air, thereby improving the heat dissipation efficiency of the motor. At the same time, since the casing is composed of two semi-cylindrical shells, which are assembled by bolts, the strip-shaped through holes are clamped with the heat sinks, making the assembly of the casing more convenient.

[0041] The rotating shaft assembly 2 includes a central shaft 22, an output shaft 21 and a terminal shaft 23. A cross-shaped slot 25 is provided at both ends of the central shaft 22. The ends of the output shaft 21 and the terminal shaft 23 are fixedly mounted with a cross-shaped clip 24. The output shaft 21 and the terminal shaft 23 are clipped with the central shaft 22 through the cross-shaped clip 24.

One end of the terminal shaft 23 away from the cross-shaped clip 24 is fixedly mounted on the inner side of the second bearing 12. The outer surface of the output shaft 21 is fixedly mounted on the inner side of the first bearing 11. The output shaft 21 passes through the first end shell 3 and extends to the outside thereof.

[0042] The outer surface of the terminal shaft 23 is provided with an annular receiving groove 26, and an arc spring 27 is installed inside the annular receiving groove 26. There are four arc springs 27, and a first clamping strip 28 is fixedly connected between the arc springs 27.

[0043] The fan assembly 7 includes a first clamping ring 71, and a first clamping groove 73 is formed on the inner side surface of the first clamping ring 71. The first clamping groove 73 is clamped and adapted with the first clamping strip 28. The outer surface of the first clamping ring 71 is fixedly mounted with a fan blade 72. When the fan assembly 7 is installed, the first clamping ring 71 squeezes the first clamping strip 28 to deform the arc spring 27, and the first clamping strip 28 enters the annular accommodating groove 26 until the first clamping groove 73 is clamped with the first clamping strip 28. When the motor is working, the fan blade 72 rotates with the terminal shaft 23 to dissipate heat, and cooperates with the ventilation holes 14 and the air holes 15 to allow air to circulate inside and outside the motor to achieve heat dissipation.

[0044] The second embodiment is based on the first embodiment. Figures 1 to 10As shown, the stator assembly 6 is arranged between the rotor 5 and the housing 1, and the stator assembly 6 penetrates the housing 1 and extends to the outside thereof. After the stator assembly 6 is energized, a magnetic field is generated to interact with the rotor 5 to realize the conversion of the electrical energy and mechanical energy of the motor. A support ring 9 is detachably installed on the outer surface of the stator assembly 6, and a base 10 is fixedly installed on the bottom of the support ring 9. The support ring 9 and the base 10 provide support for the motor as a whole, so that it can be placed stably;

[0045] The number of stator assemblies 6 is six, and the stator assembly 6 includes a stator core 601, a heat sink 602 is fixedly mounted on the outer surface of the stator core 601, a coil frame 603 is fixedly mounted on the inner side of the stator core 601, and a stator coil 604 is wound and mounted on the outer surface of the coil frame 603;

[0046] A clamping block 605 is fixedly installed on one side of the stator core 601, and a clamping groove 606 is opened on the other side of the stator core 601. The six stator cores 601 are clamped with the clamping block 605 through the clamping groove 606 to form a complete circular stator core;

[0047] A rotating shaft 607 is fixedly installed on the inner wall of the clamping groove 606, and a V-shaped clamping block 608 is rotatably installed on the outer surface of the rotating shaft 607.

A first arc-shaped clamping groove 609 is opened on the inner wall of the clamping groove 606, and a second arc-shaped clamping groove 610 is opened on the surface of the clamping block 605. The V-shaped clamping block 608 is clamped and adapted with the first arc-shaped clamping groove 609 and the second arc-shaped clamping groove 610 to assemble the stator assembly. When the adjacent stator cores 601 are connected to the clamping block 605 through the clamping groove 606 to form a complete circular stator core, when the adjacent stator cores 601 are axially spliced, the V-shaped clamping block 608 rotates and squeezes with the first arc-shaped clamping groove 609, and the V-shaped clamping block 608 is deformed. When the second arc-shaped clamping groove 610 moves to the same position as the first arc-shaped clamping groove 609, the V-shaped clamping block 608 recovers its deformation and is clamped with the second arc-shaped clamping groove 610.

[0048] The surface of the housing 1 is provided with a strip-shaped through hole 13, which is snap-fitted with the heat sink 602. The heat sink 602 enables the housing 1 and the stator assembly 6 to be firmly spliced ​​together, and exchanges heat with the surrounding air, effectively reducing the temperature inside the motor.

[0049] The third embodiment is based on the first and second embodiments. Figures 1 to 12As shown, a clamping assembly 8 is installed at both ends of the housing 1, and a first end housing 3 and a second end housing 4 are respectively installed at both ends of the housing 1 through the clamping assembly 8. The clamping assembly 8 ensures the stability of the connection, so that the motor is easy to assemble. Ventilation holes 14 and air holes 15 are respectively opened on the surfaces of the first end housing 3 and the second end housing 4. The ventilation holes 14 and the air holes 15 are used for air circulation inside and outside the motor to achieve heat dissipation. A first bearing 11 and a second bearing 12 are respectively fixedly installed at the middle of the opposite surfaces of the first end housing 3 and the second end housing 4.

[0050] The clamping assembly 8 includes a first fixing ring 801 and a second fixing ring 802. The first fixing ring 801 is fixedly mounted on the edges of the first end shell 3 and the second end shell 4 respectively, and the second fixing ring 802 is fixedly mounted on both ends of the housing 1.

[0051] A snap ring groove 803 is provided on the surface of the second fixing ring 802, a second snap ring 804 is fixedly installed on the surface of the first fixing ring 801, the second snap ring 804 is snap-fitted with the snap ring groove 803, a positioning ring groove 809 is provided at the end of the second snap ring 804, a positioning ring 810 is fixedly installed on the inner wall of the snap ring groove 803, the positioning ring 810 is squeezed and fitted with the positioning ring groove 809;

[0052] The inner part of the snap ring groove 803 is provided with a receiving groove 806, and a snap spring 807 is fixedly installed in the inner part of the receiving groove 806. The other end of the snap spring 807 is fixedly connected with a second clip strip 808. The inner side surface of the second snap ring 804 is provided with a second clip groove 805, and the second clip strip 808 is snap-fitted with the second clip groove 805. During assembly, the second snap ring 804 of the first fixing ring 801 is aligned with the snap ring groove 803 of the second fixing ring 802 at one end of the housing 1, and then the second snap ring 804 is inserted into the clip groove 803. Ring groove 803, during the insertion process, the second clamping strip 808 at one end of the clamping spring 807 in the clamping ring groove 803 will be squeezed by the second clamping ring 804. When the second clamping ring 804 is fully inserted into the clamping ring groove 803, the clamping spring 807 restores its deformation, so that the second clamping strip 808 is clamped into the second clamping groove 805 on the inner side of the second clamping ring 804. At the same time, the positioning ring groove 809 at the end of the second clamping ring 804 is squeezed and adapted with the positioning ring 810 on the inner wall of the clamping ring groove 803, completing the connection between the end shell and the housing 1.

[0053] When in use, the operator aligns the cross-shaped clamping strips 24 at the ends of the output shaft 21 and the terminal shaft 23 with the cross-shaped clamping grooves 25 at one end of the middle shaft 22, so that the output shaft 21 and the terminal shaft 23 are clamped and fixed with the middle shaft 22, completing the preliminary assembly of the rotating shaft assembly 2;

[0054] Align the first snap ring 71 of the fan assembly 7 with the terminal shaft 23, so that the inner side of the first snap ring 71 contacts the terminal shaft 23 and a certain pressure is applied. Under the action of pressure, the first snap ring 71 squeezes the first clamping strip 28 in the annular receiving groove 26 on the outer surface of the terminal shaft 23, and the arc spring 27 is deformed. The first clamping strip 28 enters the annular receiving groove 26 and continues to push the first snap ring 71 until the first clamping groove 73 on the inner side of the first snap ring 71 corresponds to the position of the first clamping strip 28. At this time, the arc spring 27 recovers its deformation, and the first clamping strip 28 is clamped into the first clamping groove 73, completing the installation of the fan assembly 7 on the terminal shaft 23;

[0055] Take the first stator core 601, align the clamping block 605 of the second stator core 601 with the clamping groove 606 of the first stator core 601, and then push the second stator core 601 axially toward the first stator core 601. During the pushing process, the V-shaped clamping block 608 in the clamping groove 606 will contact and squeeze the first arc-shaped clamping groove 609 on the clamping block 605, and the V-shaped clamping block 608 will deform and rotate around the rotating shaft 607. When the second stator core 601 continues to be pushed forward until the second arc-shaped clamping groove 610 on its clamping block 605 moves to the same position as the first arc-shaped clamping groove 609, the V-shaped clamping block 608 recovers its deformation and clamps into the second arc-shaped clamping groove 610, so that the two stator cores 601 are axially spliced ​​and clamped and fixed. The remaining four stator cores 601 are spliced ​​in turn to finally form a complete circular stator assembly 6.

During the insertion process, the second clamping strip 808 at one end of the clamping spring 807 in the snap ring groove 803 will be squeezed by the second snap ring 804. When the second snap ring 804 is completely inserted into the snap ring groove 803, the clamping spring 807 restores its deformation, so that the second clamping strip 808 is clamped into the second clamping groove 805 on the inner side of the second snap ring 804. At the same time, the positioning ring groove 809 at the end of the second snap ring 804 is squeezed and adapted with the positioning ring 810 at the inner wall of the snap ring groove 803, completing the connection between the first end shell 3 and the casing 1. Follow the same steps to install the second end shell 4 to the other end of the casing 1.
