Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic transmission, and in particular relates to a coaxial planar magnetic transmission device. Background Art

[0002] Magnetic transmission is a technology that uses magnetism to achieve contactless transmission of force or torque. In this technology, power is transmitted through a magnetic field rather than mechanical contact. Magnetic actuators or couplings typically use magnetic forces generated by permanent magnets or electromagnets to achieve power transmission. This transmission method avoids vibration transmission, ensures smooth machine operation, and provides overload protection because there is no rigid connection between the active and passive components.

[0003] A traditional magnetic transmission mechanism includes an active magnetic ring and a driven magnetic ring. Both the active magnetic ring and the driven magnetic ring have magnetic blocks. Two adjacent groups of magnetic blocks on the same magnetic ring are arranged with opposite magnetic poles. The end faces of the active magnetic ring and the driven magnetic ring are arranged in parallel. The magnetic blocks on the active magnetic ring and the driven magnetic ring attract each other, so that when the active magnetic ring rotates, it can drive the driven magnetic ring to rotate.

[0004] When the magnetic transmission mechanism is manufactured, it needs to be installed between the load unit and the drive unit as a transmission structure. Before installation, it needs to be installed in a preset device for testing. Most of the detection modules in the existing technology are set in a fixed state, resulting in a fixed distance between the active magnetic ring and the driven magnetic ring. The assembler cannot obtain the maximum spacing parameters between the active magnetic ring and the driven magnetic ring, and thus cannot obtain the complete performance parameters of the coaxial planar magnetic transmission mechanism. When it is necessary to adjust the distance between the active magnetic ring and the driven magnetic ring, it is necessary to stop the rotation of the active magnetic ring first and then adjust it. The operation is not convenient enough and needs to be improved urgently. Utility Model Content
