Description

Technical Field

[0001] The utility model relates to a forward-driving NdFeB magnetic gear, and in particular to a forward-driving NdFeB magnetic gear used in the field of magnetic gears. Background Art

[0002] Magnetic gears typically consist of a driving gear and a driven gear. Each gear is constructed with a hub and multiple permanent magnets (typically NdFeB magnets) evenly distributed around the hub's circumference. The arrangement of the permanent magnets' poles determines the distribution of the magnetic field, which in turn affects the gear's transmission performance. Because there's no direct mechanical contact between magnetic gears, they avoid the friction, wear, and noise issues common in traditional mechanical gear transmissions.

[0003] Chinese patent CN106533120A discloses a reluctance magnetic face gear set for orthogonal axis transmission, relating to the field of electromechanical transmission. This invention addresses the high cost, complex structure, and manufacturing and assembly difficulties of existing permanent magnetic face gears and bevel gears used in orthogonal axis transmission. The cylindrical gear and face gear of the present invention are designed without direct mechanical contact. This gear set is wear-free, quiet, and offers high transmission efficiency, high reliability, maintenance-free operation, and overload protection.

[0004] During the operation of the forward-drive magnetic gear, when it is used in some workshops with a lot of floating objects, dust in the air is easy to adhere to the gear surface. Some metal particles or conductive substances in the dust may interfere with the magnetic field of the magnetic gear, affecting its normal working performance. When the dust is sucked away by suction, it is difficult to suck away all the stubborn attachments. Therefore, it is necessary to design a forward-drive magnetic gear with an auxiliary attachment cleaning function to solve the above problems. Utility Model Content

[0005] In response to the above-mentioned existing technology, the technical problem to be solved by the present invention is that when the forward-transmitting magnetic gear is used in some workshops with a lot of floating objects during operation, dust in the air is easily attached to the surface of the gear, and some metal particles or conductive substances in the dust may interfere with the magnetic field of the magnetic gear, affecting its normal working performance.

[0006] In order to solve the above problems, the utility model provides a forward-transmitting neodymium iron boron magnetic gear, comprising a first conveying roller and a second conveying roller corresponding to each other in the upper and lower directions, the outer end of the first conveying roller is fixedly connected to the first magnetic gear, the outer end of the second conveying roller is fixedly connected to the second magnetic gear, one end of the first conveying roller and the second conveying roller are both equipped with a bearing outer ring member, the lower end of the bearing outer ring member is fixedly connected to an extended vertical plate, the lower end of the extended vertical plate is equipped with a rotating shaft bar, the outer end of the rotating shaft bar is fixedly connected to a thin-surface rubber linkage rotating plate, the upper end of the thin-surface rubber linkage rotating plate is fixedly connected to a flexible wiping surface, the inner end of the thin-surface rubber linkage rotating plate is provided with an interlayer space, and the inner end of the interlayer space is fixedly connected to a plurality of electromagnetic blocks at equal distances.

[0007] In the above-mentioned forward-transmitting magnetic gear, this solution uses an external control terminal to drive the electromagnetic blocks arranged inside the thin-surface rubber linkage rotating plate to energize, thereby achieving the effect of being close but not in contact. At this time, the thin-surface rubber linkage rotating plate rotates through the rotating shaft rod under the action of magnetic attraction. After rotation, the flexible wiping surface can contact the corresponding magnetic surface and generate friction, thereby assisting in erasing the corresponding magnetic surface, that is, the attachments on the outer surfaces of the first magnetic gear and the second magnetic gear.

[0008] As a further improvement of the present application, the electromagnetic block is located below the interlayer space, and the first conveying roller is externally connected to a motor.

[0009] As a further improvement of the present application, a plurality of spring resistance members are fixedly connected between the flexible wiping surface and the thin rubber linkage rotating plate.

[0010] As a further improvement of the present application, two thin rubber linkage rotating plates are respectively located directly below the corresponding first magnetic gear and second magnetic gear.

[0011] As another improvement of the present application, the two flexible wiping surfaces are in contact with the outer side walls of the corresponding first magnetic gear and the second magnetic gear, and a threaded sleeve is movably connected between the two horizontally arranged thin rubber linkage rotating plates.

[0012] As another improved supplement to the present application, the rotating shaft bar protrudes from both sides of the thin rubber linkage rotating plate, and the left and right ends of the threaded sleeve are threadedly connected to the two horizontally arranged rotating shaft bars.

[0013] As another improved supplement of the present application, the multiple electromagnetic blocks are externally connected to a control terminal, and the outer ends of the first magnetic gear and the second magnetic gear are fixedly connected to a protective coating.

[0014] In summary, this solution uses an external control terminal to drive the electromagnetic blocks arranged in the thin-surface rubber linkage rotating plate to energize, so that it can approach the corresponding first magnetic gear or the second magnetic gear, and find a suitable angle during assembly to balance the attraction and repulsion between the electromagnetic block and the corresponding magnetic surface, thereby achieving the effect of being close but not in contact. At this time, the thin-surface rubber linkage rotating plate rotates through the rotating shaft rod under the action of magnetic attraction. After rotation, the flexible wiping surface can contact and generate friction with the corresponding magnetic surface, and then assist in erasing the corresponding magnetic surface, that is, the attachments on the outer surface of the first magnetic gear and the second magnetic gear. At the same time, by controlling the power on and off of the electromagnetic blocks at different positions, the flexible wiping surfaces in different areas can be brought into contact and wiped with the first magnetic gear, so that the wiping area of the flexible wiping surface corresponding to the first magnetic gear can be flexibly changed, and the wiping effect is better.

DETAILED DESCRIPTION

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-6 It shows that it includes a first conveying roller 2 and a second conveying roller 4 corresponding to each other in the upper and lower parts. The outer end of the first conveying roller 2 is fixedly connected to the first magnetic gear 3, and the outer end of the second conveying roller 4 is fixedly connected to the second magnetic gear 5. One end of the first conveying roller 2 and the second conveying roller 4 is installed with a bearing outer ring part 6, the lower end of the bearing outer ring part 6 is fixedly connected to the extended vertical plate 7, the lower end of the extended vertical plate 7 is installed with a rotating shaft bar 8, the outer end of the rotating shaft bar 8 is fixedly connected to a thin-surface rubber linkage rotating plate 9, the upper end of the thin-surface rubber linkage rotating plate 9 is fixedly connected to a flexible wiping surface 10, the inner end of the thin-surface rubber linkage rotating plate 9 is opened with an interlayer space 13, and the inner end of the interlayer space 13 is fixedly connected to a plurality of electromagnetic blocks 12 at equal distances.

[0027] Figure 1-6 It is shown that the electromagnetic block 12 is located below the interlayer space 13, the first conveying roller 2 is externally connected to the motor 1, and multiple spring resistance members 11 are fixedly connected between the flexible wiping surface 10 and the thin rubber linkage rotating plate 9. The two thin rubber linkage rotating plates 9 are respectively located directly below the corresponding first magnetic gear 3 and the second magnetic gear 5. The two flexible wiping surfaces 10 are in contact with the outer side walls of the corresponding first magnetic gear 3 and the second magnetic gear 5. The multiple electromagnetic blocks 12 are all externally connected to the control terminal, and the outer ends of the first magnetic gear 3 and the second magnetic gear 5 are fixedly connected to the protective coating 15.

[0028] Figure 1-6The present invention shows a forward-driven neodymium iron boron magnetic gear. In this solution, the motor 1 drives the first conveyor roller 2 to rotate the first magnetic gear 3 on its outer side. When the first magnetic gear 3 rotates, the second magnetic gear 5 on its lower side can rotate in the opposite direction. During the rotation of the first magnetic gear 3 and the second magnetic gear 5, the attachments on their surfaces can be removed by arranging a thin rubber linkage rotating plate 9 directly below them. When the surface attachments need to be cleaned, the electromagnetic block 12 arranged in the thin rubber linkage rotating plate 9 is driven by an external control terminal to energize. After the electromagnetic block 12 is energized, it can approach the corresponding first magnetic gear 3 or second magnetic gear 5, and find a suitable angle during assembly to balance the attraction and repulsion between the electromagnetic block 12 and the corresponding magnetic surface, thereby achieving close but not close contact. The contact effect, at this time, the thin rubber linkage rotating plate 9 rotates through the rotating shaft rod 8 under the action of magnetic attraction, and the flexible wiping surface 10 can contact with the corresponding magnetic surface after rotation and generate friction, and then assist in erasing the corresponding magnetic surface, that is, the attachments on the outer surface of the first magnetic gear 3 and the second magnetic gear 5. At the same time, by controlling the power on and off of the electromagnetic blocks 12 at different positions, the flexible wiping surfaces 10 in different areas can be brought into contact and wiped with the first magnetic gear 3, so that the wiping area of the flexible wiping surface 10 corresponding to the first magnetic gear 3 can be flexibly changed, and the wiping effect is better. At the same time, an interlayer space 13 is set in the thin rubber linkage rotating plate 9, and the spring resistance member 11 in the interlayer space 13 can make the contact surface of the flexible wiping surface 10 and the magnetic surface closer, so that its wiping efficiency is better.

[0029] Second implementation method:

[0030] Figure 7 A forward-transmitting NdFeB magnetic gear is shown, wherein a threaded sleeve 14 is movably connected between two horizontally arranged thin-surface rubber linkage rotating plates 9, and a rotating shaft bar 8 protrudes from both sides of the thin-surface rubber linkage rotating plates 9. The left and right ends of the threaded sleeve 14 are threadedly connected to the two horizontally arranged rotating shaft bars 8. A threaded sleeve 14 connected by a stud is provided between the two thin-surface rubber linkage rotating plates 9. The threaded sleeve 14 can connect multiple groups of thin-surface rubber linkage rotating plates 9 to each other, thereby playing a unified linkage role, and can enable a group of electromagnetic blocks 12 to link multiple groups of thin-surface rubber linkage rotating plates 9 to generate rotational force, thereby effectively reducing the cost of the cleaning function.

[0031] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
