DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] See also Figure 1-Figure 5 , the utility model provides a magnetic transmission device, including a support assembly 100 and a magnetic transmission assembly 200;
[0025] The support assembly 100 includes a bottom plate 101, with side plates 102 fixedly connected to both sides of the bottom plate 101. Two support plates 103 are movably mounted on the upper end of the bottom plate 101. The surface of the support plates 103 is provided with a fixing groove 104, and the interior of the fixing groove 104 is provided with a bearing 105.
[0026] The magnetic transmission assembly 200 includes two mounting disks 201, and the opposite surfaces of the two mounting disks 201 are provided with a plurality of mounting slots 202. The interiors of the plurality of mounting slots 202 are staggeredly installed with positive and negative magnets 203. The surface of one of the mounting disks 201 is connected to an output shaft 204, and one end of the output shaft 204 is connected to a servo motor 205. The surfaces of the two mounting disks 201 are clamped with a limiting shell 206, and the surface of the limiting shell 206 is connected to a limiting plate 207. The surface of the other mounting disk 201 is fixedly connected to a transmission shaft 208.
[0027] In a specific embodiment, the support component 100 is set in conjunction with the magnetic transmission component 200, which not only can achieve the effect of magnetic transmission, but also can avoid mechanical wear and damage to the servo motor 205 caused by excessive torque, thereby extending the service life of the servo motor 205. In addition, the above-mentioned structures cooperate with each other to improve the stability of the transmission device and facilitate disassembly of the transmission device, thereby improving the convenience of use of the transmission device. When in use, the servo motor 205 is first started to rotate with the output shaft 204, the mounting disk 201 and several staggered positive and negative magnets 203 inside the mounting slot 202. Since a magnetic field is generated between the staggered positive and negative magnets 203 on the opposite surfaces of the two mounting disks 201, when the servo motor 205 rotates with the output shaft 204, it can also rotate with the other mounting disk 201 and the transmission shaft 208, thereby achieving the purpose of magnetic transmission, and there is no mechanical wear between the output shaft 204 and the transmission shaft 208, thereby avoiding damage to the servo motor 205 and extending its service life.
[0028] See also Figure 2 The upper end of the bottom plate 101 is fixedly connected with a plurality of plug-in blocks 111 , and the lower ends of the two support plates 103 are each provided with two plug-in slots 112 , and the plug-in blocks 111 are plugged into the interior of the plug-in slots 112 .
[0029] In a specific embodiment, the insertion of the plug-in block 111 into the insertion slot 112 not only facilitates the installation of the support plate 103 and the bottom plate 101 , but also allows the support plate 103 to be disassembled by taking out the plug-in block 111 .
[0030] See also Figure 3-Figure 5 The end of the output shaft 204 away from the servo motor 205 is fixedly connected to the limiting shaft 211, and the surface of one of the mounting plates 201 is fixedly connected to a connecting shaft 212, and a limiting groove 213 is defined at one end of the connecting shaft 212, and the limiting shaft 211 is inserted into the inside of the limiting groove 213.
[0031] In a specific embodiment, the limiting shaft 211 is inserted into the limiting groove 213 to facilitate the installation of the output shaft 204 and the mounting disk 201 , and the mounting disk 201 can be disassembled by removing the limiting shaft 211 .
[0032] See also Figure 3-Figure 5 The side surface of the limiting shell 206 is provided with a plurality of card slots 221 , and the side surface of the limiting piece 207 is fixedly connected with a plurality of card blocks 222 , and the plurality of card blocks 222 are all clamped in the interior of the card slots 221 .
[0033] In a specific embodiment, the clamping block 222 is clamped inside the clamping slot 221 to install the limiting shell 206 and the limiting plate 207, thereby limiting the installation disk 201 and the positive and negative magnets 203. After the clamping block 222 is removed, the limiting shell 206 can be disassembled.
[0034] See also Figure 3-Figure 5 The output shaft 204 and the transmission shaft 208 are both inserted into the bearing 105 .
[0035] In a specific embodiment, the presence of the bearing 105 can reduce the friction between the output shaft 204 and the transmission shaft 208 and improve the stability of the transmission shaft 208 during rotation.
[0036] See also Figure 3-Figure 5 The limiting shell 206 and the limiting piece 207 are both made of plastic.
[0037] In a specific embodiment, the limiting shell 206 and the limiting piece 207 made of plastic can not only limit the positive and negative magnets 203, but also prevent the positive and negative magnets 203 from being attracted to each other and affecting the magnetic field.
[0038] See also Figure 3-Figure 5 , the mounting plate 201 is made of aluminum alloy.
[0039] In a specific embodiment, the mounting plate 201 made of aluminum alloy can improve the protection effect of the positive and negative magnets 203, while avoiding mutual adsorption with the positive and negative magnets 203, which affects the convenience of use.
[0040] Working principle: When in use, first start the servo motor 205 to rotate with the output shaft 204, the mounting disk 201 and several staggered positive and negative magnets 203. Since a magnetic field is generated between the positive and negative magnets 203 staggered on the opposite surfaces of the two mounting disks 201, when the servo motor 205 rotates with the output shaft 204, one mounting disk 201 rotates with the other mounting disk 201 and the transmission shaft 208, thereby achieving the purpose of magnetic transmission. At the same time, there is no mechanical wear between the output shaft 204 and the transmission shaft 208, thereby avoiding mechanical fatigue, and then avoiding damage to the servo motor 205 to extend its service life.
