[0023] The utility model will be further described in detail below in combination with the drawings.

[0024] As Figures 1 to 7 shown, the magnetic coupling type magnetic isolation angle transmission assembly comprises a driving wheel and a driven wheel matched with each other, and the number ratio of the driving wheel to the driven wheel is 1:3. The driving wheel comprises a first toothed disc 1, which is an annular body. A groove 11 is arranged at intervals around the outer wall of the first toothed disc 1. A tooth sleeve 3 is connected at each groove 11. A protrusion 31 is arranged on the inner side of the tooth sleeve 3 and matched with the groove 11. An extension 32 is formed on the outer side of the lower end of the tooth sleeve 3 and extends outward. The angle between the extension 32 and the axis of the first toothed disc 1 can be a right angle or an obtuse angle. The obtuse angle can be 112 degrees. The tooth sleeve 3 is fixed on the first toothed disc 1 by means of a screw passing through the tooth sleeve 3 and the groove 11 in sequence. The adjacent tooth sleeves 3 are in contact with each other. A first magnetic steel 5 is arranged on the extension 32 of the tooth sleeve 3. A tooth sleeve pressing plate 4 opposite to the extension 32 is arranged above the first magnetic steel 5. The first magnetic steel 5 is fixed on the extension 32 of the tooth sleeve 3 by means of a screw passing through the tooth sleeve pressing plate 4, the first magnetic steel 5 and the extension 32 in sequence. The fixing structure is simple, and the effective area of the coupling of the first magnetic steel 5 is increased, so that the transmission efficiency can be increased. The first magnetic steel 5 is square and arranged on the tooth sleeve 3 in an alternating manner of N pole and S pole.

[0025] The first toothed disc 1, the tooth sleeve 3 and the tooth sleeve pressing plate 4 are all made of stainless steel, which is corrosion-resistant and can avoid negative interference on the magnetic field.

[0026] The driven wheel comprises a second toothed disc 2, which is an annular body and provided with an axle hole at one end. Small tooth disc covers 6 are fixed on the outer sides of the upper and lower ends of the second toothed disc 2 by means of screws. The small tooth disc covers 6 are annular. Second magnetic steels 7 are arranged on the inner side of the small tooth disc covers 6. The second magnetic steels 7 on the same side are arranged in an alternating manner of N pole and S pole. The second magnetic steels 7 on the upper and lower sides are arranged in an attracting manner of N pole and S pole. The second magnetic steels 7 on the opposite sides and the first magnetic steels 5 form a non-contact coupling structure. The small tooth disc covers 6 on the upper and lower sides form a C-shaped structure with the second toothed disc 2. The material of the second toothed disc 2 and the small tooth disc covers 6 is carbon steel, which is conducive to the convergence of the magnetic field and reduces the possibility of magnetic field divergence and overflow. The magnetic field can be shielded to prevent the magnetic field from overflowing and affecting nearby devices that may have a certain sensitivity to the magnetic field. The C-shaped structure between the second toothed disc 2 and the small tooth disc covers 6 forms a closed loop for the magnetic field, which greatly reduces the spatial distance of the magnetic field radiation. According to the finite element analysis and calculation, the magnetic field overflow intensity outside the space with a distance greater than 150 mm is less than 2Gs. The influence on sensitive devices such as electromagnetic equipment and electronic equipment can be completely ignored.

[0027] Because the magnetic field loop is closed, the magnetic flux is highly concentrated in the coupling region. In addition, the coupling area of ​​the first magnet 5 is large, resulting in a significant increase in the coupling transmission torque between the large and small gears. According to user needs, the distance between the first magnet 5 and the second magnet 7, i.e. the coupling air gap, can be adjusted arbitrarily within the range of 3mm-10mm. Using finite element calculations, when the single-sided coupling air gap is 4.5mm, the maximum coupling torque of the large gear can reach 160Nm, and the coupling torque of the small gear can also reach 30Nm. The rotational torque can handle most working conditions, and the sufficiently large transmission torque can also ensure that the large gear drives multiple small gear disks and ensure that the rotational speed of all small gear disks is consistent and stable.

[0028] This utility model of a magnetic coupling type magnetically isolated angle transmission component involves setting a toothed sleeve 3 on the side wall of the first toothed disc 1 of the driving wheel and fixing a first magnet 5 at the front end of the toothed sleeve 3. The first magnet 5 is arranged with alternating N and S poles. The driven wheel is coupled to the first magnet 5 by the upper and lower opposite second magnets 6, forming a non-contact coupling. The second magnets 6 on the same side are arranged with alternating N and S poles, and the second magnets 6 on the opposite side are arranged with N and S poles attracting each other. The non-contact coupling eliminates the inconvenience caused by the friction and wear of traditional gears, and can achieve a maintenance-free system, reducing system maintenance costs.

[0029] Finally, it should be noted that the above embodiments only illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
