Description

Technical Field

[0001] The present application relates to the field of non-contact transmission technology, and in particular to a magnetic shaft transmission mechanism and a transmission device. Background Art

[0002] In the prior art, traditional methods of rotational drive include the following: shaft connection drive, gear meshing drive, synchronous belt, and belt drive. With the above rotational drive methods, the driving source and the driven rotating mechanism need to be in contact to achieve the desired effect. For mechanisms that require both revolution and rotation, the rotation of the shaft must be driven by contact in order to achieve rotation while revolving. The friction between the various accessories is large, which can easily lead to wear of the accessories. Utility Model Content

[0003] In order to improve the problem of easy wear of accessories caused by friction in contact transmission, the present application provides a magnetic shaft transmission mechanism and a transmission device.

[0006] A transmission device using a magnetic shaft transmission mechanism includes the above-mentioned magnetic shaft transmission mechanism, including: a revolving disk, a motor, a main driving magnetic shaft and a plurality of driven magnetic shafts, the revolving disk is rotatable, the plurality of driven magnetic shafts are distributed along the circumference of the revolving disk, the driven magnetic shafts are rotatably connected to the revolving disk, the motor is arranged below the revolving disk, the output shaft of the motor faces the revolving disk, the main driving magnetic shaft is fixed to the output shaft of the motor, and the main driving magnetic shaft and the driven magnetic shaft correspond in position.

[0007] The magnetic shaft transmission mechanism and transmission device provided by the embodiments of the present disclosure can achieve the following technical effects:

[0008] The interaction force between the two magnetic shafts can realize the rotation of the drive shaft without contact. There is no contact between the main drive magnetic shaft and the driven magnetic shaft, which reduces the wear caused by friction. The permanent magnetic parts have strong power transmission capabilities, no wear, no dust, no noise, no maintenance, no replacement, good dynamic balance, and high position control accuracy. The size of the interaction force can be adjusted by adjusting the distance between the main drive magnetic shaft and the driven magnetic shaft to meet different loads. When using this transmission mechanism, only the main drive magnetic shaft and the driven magnetic shaft need to be fixed, which helps save space and reduce the complexity of the transmission.

[0016] The following is combined with Figure 1-3 This application is described in further detail.

[0017] A magnetic shaft transmission mechanism includes: a main driving magnetic shaft 1 and a driven magnetic shaft 2, the main driving magnetic shaft 1 and the driven magnetic shaft 2 are arranged longitudinally opposite to each other, the opposite side walls of the main driving magnetic shaft 1 and the driven magnetic shaft 2 are each provided with a plurality of permanent magnets 3, the main driving magnetic shaft 1 is fixed to the output shaft 5 of the motor 4, and the driven magnetic shaft 2 is provided with a load fixing seat 6.

[0018] In this embodiment, the shapes of the main driving magnetic shaft 1 and the driven magnetic shaft 2 are both cylindrical, and the number of the plurality of permanent magnets 3 is 6, and the 6 permanent magnets 3 are evenly distributed and corresponding in position along the circumferential direction of the side walls of the main driving magnetic shaft 1 and the driven magnetic shaft 2. In actual use, the motor 4 is started, and the output shaft 5 of the motor 4 drives the main driving magnetic shaft 1 to rotate, thereby driving the driven magnetic shaft 2 to rotate and driving the load to rotate, thereby realizing the transmission function.

[0019] By adopting the above structure, the rotation of the drive shaft can be achieved without contact through the interaction force of the two magnetic shafts. There is no contact between the main driving magnetic shaft 1 and the driven magnetic shaft 2, which reduces the wear caused by friction, and the permanent magnetic parts have strong power transmission capabilities, no wear, no dust, no noise, no maintenance, no replacement, good dynamic balance, and high position control accuracy. The size of the interaction force can be adjusted by adjusting the distance between the main driving magnetic shaft 1 and the driven magnetic shaft 2 to meet different loads. When using this transmission mechanism, it is only necessary to fix the main driving magnetic shaft 1 and the driven magnetic shaft 2, which helps to save space and reduce the complexity of the transmission.

[0020] A transmission device using a magnetic shaft transmission mechanism includes the above-mentioned magnetic shaft transmission mechanism, specifically including: a revolving disk 7, a motor 4, a main driving magnetic shaft 1 and a plurality of driven magnetic shafts 2, the revolving disk 7 is rotatable, the plurality of driven magnetic shafts 2 are distributed circumferentially along the revolving disk 7, the driven magnetic shafts 2 are rotatably connected to the revolving disk 7, the motor 4 is arranged below the revolving disk 7, the output shaft 5 of the motor 4 faces the revolving disk 7, the main driving magnetic shaft 1 is fixed to the output shaft 5 of the motor 4, and the main driving magnetic shaft 1 and the driven magnetic shaft 2 correspond in position.

[0021] In one embodiment, the shape of the rotating disk 7 is a circle, and a plurality of driven magnetic shafts 2 are evenly distributed along the circumference of the rotating disk 7. After the rotating disk 7 rotates and aligns one of the driven magnetic shafts 2 with the main driving magnetic shaft 1 below in the longitudinal direction, the starting motor 4 drives the main driving magnetic shaft 1 to rotate, thereby driving the driven magnetic shaft 2 to rotate, thereby completing the transmission process. After a transmission process is completed, the rotating disk 7 continues to rotate, aligns the next driven magnetic shaft 2 with the main driving magnetic shaft 1 below in the longitudinal direction, and repeats the above process.
