[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 The present invention provides the following technical solution:

[0029] Example 1: To solve the problems existing in the use of existing non-contact gears, this example provides a magnetic levitation non-contact gear, including a first gear body 1 and a second gear body 2. The first gear body 1 includes a first positioning ring 3. Locking plates 5 covering the outside of the first positioning ring 3 are provided at equal angles on the upper and lower sides of the first gear body 1. The outer wall of the first positioning ring 3 is provided with a first locking groove 6 for snap-fit ​​positioning at equal angles. The first locking groove 6 is used to realize the installation of the overlapping positioning block 7. The outer side of the first positioning ring 3 is provided with a first magnetic tooth block 9 at equal angles so that the first magnetic tooth block 9 can perform magnetic non-contact meshing with the second gear body 2.

[0030] The second positioning ring 4 is installed by engaging with the overlapping positioning block 7 through the first locking groove 6 opened at an equal angle on the outside. The overlapping positioning block 7 is provided with a positioning bolt 8 at the end away from the first locking groove 6, and the overlapping positioning block 7 is detachably locked in the first locking groove 6 on the outside of the second positioning ring 4 by the positioning bolt 8.

[0031] likeFigures 3-4 As shown, the inner end of the overlapping positioning block 7 is first symmetrically installed in the first locking groove 6 opened on the outer side of the first positioning ring 3, so that the first locking groove 6 positions the overlapping positioning block 7. Then, the overlapping positioning block 7 is locked and fixed inside the first locking groove 6 by the positioning bolt 8. At the same time, when replacing, the corresponding positioning bolt 8 can be removed to disassemble the required overlapping positioning block 7, avoiding the overall disassembly from affecting the efficiency of maintenance.

[0032] Example 2: To solve the problems existing in the use of existing non-contact gears, this example adopts the following technical solution: the outer end of the first magnetic tooth block 9, which is set at equal angles, is slidably installed on the end of the overlapping positioning block 7 away from the second positioning ring 4 through a concave-convex structure, and the first magnetic tooth block 9, the overlapping positioning block 7, and the second positioning ring 4 form a downwardly inclined frustum-shaped structure; the locking pieces 5, which are set at equal angles, are combined to form a circular structure with the same center as the second positioning ring 4, and the locking pieces 5, which are set at equal angles, are provided with a first locking bolt 10 on the side close to the second positioning ring 4, and the locking pieces 5 are detachably installed on the upper and lower sides of the second positioning ring 4 by the first locking bolt 10.

[0033] The outer ends of the locking pieces 5, which are set at equal angles, cover the connection between the corresponding overlapping positioning block 7 and the first magnetic tooth block 9, so that the locking pieces 5 can position the first magnetic tooth block 9 and prevent the first magnetic tooth block 9 from shifting or misaligning.

[0034] like Figure 2 , Figure 6 As shown, the inner end of the first magnetic tooth block 9 is slidably inserted into the outer end of the overlapping positioning block 7 so that the first magnetic tooth block 9 and the overlapping positioning block 7 have a concave-convex structure to achieve locking and positioning. The remaining first magnetic tooth blocks 9 are then installed accordingly. Then, the upper and lower distributed locking pieces 5 are installed on the outside of the first magnetic tooth block 9 and the overlapping positioning block 7 respectively. The locking pieces 5 on the upper and lower sides are fixed to the outside of the overlapping positioning block 7 by the first locking bolt 10. At the same time, the outer end of the locking piece 5 covers the connection of the first magnetic tooth block 9 so as to limit it to the outer end of the overlapping positioning block 7 and prevent the first magnetic tooth block 9 from shifting or misaligning during the force process.

[0035] Furthermore, when it is necessary to replace the worn first magnetic tooth block 9, it is only necessary to remove the first locking bolts 10 and locking plates 5 on its upper and lower sides, and remove and replace the corresponding first magnetic tooth block 9 from the outer end of the overlapping positioning block 7, thereby improving the ease of disassembling the first magnetic tooth block 9.

[0036] Example 3: In order to solve the problems existing in the use of existing non-contact gears, this example adopts the following technical solution: the second gear body 2 includes a second positioning ring 4, the outer end of the second positioning ring 4 is provided with a second locking groove 11 at equal angles, and the outer end of the second positioning ring 4 is provided with a second magnetic tooth block 12 corresponding to the second locking groove 11 at equal angles, and the second magnetic tooth block 12 and the second locking groove 11 are slidably engaged and connected by a concave-convex structure.

[0037] Locking rings 13 are provided on both the upper and lower sides of the second positioning ring body 4. The locking rings 13 are symmetrically arranged with second locking bolts 14 at equal angles inside. The locking rings 13 are detachably locked and installed on the upper and lower sides of the second positioning ring body 4 by the second locking bolts 14. The symmetrically arranged locking rings 13 limit the second magnetic tooth block 12 in the second locking groove 11 at the outer end of the second positioning ring body 4. The magnetism of the second magnetic tooth block 12 is the same as that of the first magnetic tooth block 9, so that they do not make contact when they mesh with each other due to the repulsive force.

[0038] like Figure 1 , Figure 5 As shown, the second magnetic tooth block 12 is inserted into the second locking groove 11 opened at the outer end of the second positioning ring body 4 at equal angles, and the locking rings 13 distributed on the upper and lower sides are fixedly installed on the outside of the second positioning ring body 4 by the second locking bolts 14, so that the locking rings 13 cover the connection between the second magnetic tooth block 12 and the second positioning ring body 4, ensuring the stability of the installation of the second magnetic tooth block 12.

[0039] Meanwhile, the magnetism of the first magnetic tooth block 9 is the same as that of the second magnetic tooth block 12, so that when the first gear body 1 and the second gear body 2 mesh through the first magnetic tooth block 9 and the second magnetic tooth block 12, the first magnetic tooth block 9 and the second magnetic tooth block 12 are prevented from contacting each other by magnetic repulsion, thereby preventing powder from falling off during transmission rotation.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
