Description

Technical Field

[0001] The utility model belongs to the technical field of motors and relates to a stator and rotor, in particular to a stator and rotor with good dustproof effect. Background Art

[0002] In order to enhance heat dissipation, ventilation holes are opened on the end covers of the stator and rotor assemblies. However, the opening of the ventilation holes will cause the stator and rotor assemblies to be connected to the outside world. Considering that there is a lot of metal dust in the working environment of the stator and rotor assemblies, the metal dust can easily enter the stator and rotor through the ventilation holes, causing a short circuit in the coils in the stator and rotor, or an abnormal magnetic field in the stator and rotor, resulting in a decrease in the power of the stator and rotor.

[0003] Later, a dust screen 71 was installed at the vent to intercept metal dust. However, the dust screen installed on the vent is not easy to remove in actual use. Direct cleaning is not only inefficient, but also has poor cleaning effect because the dust screen contains electronic equipment that cannot be washed with water, and requires frequent cleaning. At the same time, when the dust screen is removed, dust easily enters the stator and rotor, resulting in a reduced service life.

[0004] For example, the patent number CN201922346439.0 is a motor stator and rotor structure. This patent uses a spring and a positioning protrusion to install the dustproof pad on the stator and rotor. Pressing the positioning protrusion can complete the fixing and unlocking of the dustproof pad, which facilitates the installation of the dustproof pad.

[0005] The above patent is designed with only one layer of dustproof pad. When the positioning protrusion is pressed, vibration will be generated. The vibration may shake the dust off the dustproof pad, causing the dust to fall into the stator and rotor, affecting the normal use of the stator and rotor. Utility Model Content

DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figures 1 to 6 As shown, the utility model can be implemented through the following embodiments: a stator and rotor with good dustproof effect, including a stator 1, a rotor 2, a rotating shaft 3 and a shell 4, mounting covers 5 are installed at both ends of the shell 4, a mounting groove 1 51 is opened on the mounting cover 5, a mounting groove 2 52 is opened at the bottom of the mounting groove 1 51, a vent 521 is opened at the bottom of the mounting groove 2 52, a dustproof pad 6 is installed in the mounting groove 1 51, a dustproof frame 7 is installed in the mounting groove 2 52, a dustproof net 71 is installed at the bottom of the dustproof frame 7, and the dustproof pad 6 is installed on the dustproof frame 7.

[0026] The utility model is provided with a dustproof pad 6 and a dustproof frame 7. The dustproof net 71 and the dustproof frame 7 cooperate to improve the dustproof effect of the stator and rotor. The dustproof frame 7 is convenient for intercepting powder, and dust is not easy to enter the stator and rotor during disassembly.

[0027] like Figure 4 As shown, a mounting frame 61 is provided outside the dustproof pad 6. The mounting frame 61 is provided to provide a component for fixing the dustproof pad 6, so as to facilitate the disassembly and assembly of the dustproof pad 6.

[0028] like Figure 4 As shown, a plurality of slots 62 are provided on the mounting frame 61, and a fixing slot 621 is provided on the slots 62. The slots 62 are used for the fixing member to pass through the mounting frame 61, and the fixing slots 621 are used for the fixing member to lock the dustproof pad 6.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, a mounting hole 511 is provided on the mounting slot 1 51, a spring 8 is installed in the mounting hole 511, and a rotating block 9 is installed on the spring 8. The rotating block 9 is used to indirectly fix the dustproof pad 6 by fixing the mounting frame 61, and the spring 8 provides a locking force for locking the mounting frame 61.

[0030] like Figure 4 and Figure 6As shown, a fixing block 91 is provided at the front end of the rotating block 9, and the fixing block 91 matches the fixing groove 621. The fixing block 91 matches the fixing groove 621 to limit the rotation of the rotating block 9, improve the effect of the rotating block 9 locking the mounting frame 61, and prevent the rotating block 9 from being separated from the fixing groove 621 when the stator and rotor are working.

[0031] like Figure 2 and Figure 6 As shown, a rotating cover 92 is provided on the end of the rotating block 9, and the spring 8 is fixed on the rotating cover 92. The arrangement of the rotating cover 92 facilitates the rotating block 9 to rotate relative to the spring 8, so that the fixing block 91 can be inserted into the fixing groove 621.

[0032] like Figure 2 , Figure 3 and Figure 5 As shown, a limit block 72 is provided on the dustproof frame 7, a magnet is installed on the limit block 72, and a corresponding limit hole 522 is opened on the second mounting groove 52. The limit block 72 and the limit hole 522 cooperate to limit the displacement of the dustproof frame 7 in the second mounting groove 52, and the arrangement of the magnet fixes the dustproof frame 7 in the mounting groove to prevent the dustproof frame 7 from escaping from the mounting groove when the stator and rotor are working, and colliding with the dustproof pad 6 to generate noise.

[0033] like Figure 2 and Figure 5 As shown, a buffer pad 73 is fixed on the dustproof frame 7, and the buffer pad 73 is sandwiched between the dustproof frame 7 and the mounting frame 61. The buffer pad 73 is used to separate the dustproof frame 7 and the dustproof pad 6 to prevent noise and reduction of dustproof effect caused by collision. At the same time, the buffer pad 73 will lift up the dustproof net 71, making the installation of the dustproof net 71 and the dustproof frame 7 more stable.

[0034] like Figure 6 As shown, a hexagonal groove 93 is provided on the rotating block 9, a metal body 931 is installed in the hexagonal groove 93, and the rotating block 9 is made of plastic material. The hexagonal groove 93 is provided to facilitate the use of an inner hexagonal wrench to rotate the rotating block 9, and the metal body 931 is provided to tighten the inner hexagonal wrench, so that the rotating block 9 can overcome the pulling force of the spring 8, so that the fixed block 91 on the rotating block 9 can be inserted into the fixed groove 621. The rotating block 9 made of plastic material reduces the mass, which is convenient for the inner hexagonal wrench to pull the rotating block 9.

[0035] The working principle of the utility model is as follows: after the stator and rotor components are assembled, the dustproof frame 7 is inserted into the mounting slot 2 52 of the mounting cover 5, and then the dustproof pad 6 is installed on the dustproof frame 7, and the mounting frame on the dustproof pad 6 is installed in the mounting slot 1 51, and the card slot 62 on the mounting frame is opposite to the rotating block 9, and a magnetic hexagonal wrench is used to suck the metal body 931, and the rotating block 9 is pulled at the same time, and finally the rotating block 9 is rotated so that the fixed block 91 on the rotating block 9 is inserted into the fixed slot 621, and the dustproof pad 6 is fixed. For disassembly and replacement, the above steps can be reversed to remove the parts.

[0036] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
