Problems solved by technology
[0003] In the field of traditional magnetic coupling design, when the machining accuracy is relatively high between the copper plate and the mounting plate, there is a gap between the copper plate and the mounting plate, and the air in the gap is a poor conductor of heat. , and it is easy to cause dust in the air to enter the gap, so it cannot effectively ensure the effective heat conduction between the copper plate and the mounting plate

A permanent magnet coupler copper disc and mounting disc potting heat conduction structure comprises an input mounting disc. The input installation disc and the output installation disc are installed on the two sides of the output square shaft assembly respectively, the inner side of the input installation disc and the inner side of the output installation disc are in threaded connection with an input copper disc and an output copper disc through copper disc fastening screws respectively, and heat conduction silicone grease is smeared between the input copper disc and the input installation disc and between the output copper disc and the output installation disc. A magnetic disc assembly is installed on a square shaft of the output square shaft assembly, the input installation disc is in threaded connection with an input assembly through input assembly installation bolts, the top of the input installation disc and the top of the output installation disc are sleeved with cylinders, and cooling fins are installed on the outer side of the input installation disc and the outer side of the output installation disc through cooling fin fastening screws respectively. And heat conduction silicone grease is coated between the copper disc and the mounting disc to fill the gaps, so that heat conduction is smoother. Resin is smeared on the outer surface of the copper disc for a vacuum encapsulation technology, so that vacuum insulation and effective sealing between the copper disc and the mounting disc are ensured.
Description
technical field [0001] The invention belongs to the technical field of couplers, in particular to a potting heat conduction structure of a copper plate and a mounting plate of a permanent magnet coupler. Background technique [0002] In the field of magnetic coupling design, there is a magnetic coupling, which drives the conductor rotor to cut magnetic lines of force in the strong magnetic field generated by the permanent magnet rotor when the motor rotates, thus generating eddy currents in the conductor disk. Thereby, the anti-magnetic field and the magnetic field of the permanent magnet rotor cut the magnetic field line to drive the rotation, and the number of revolutions is controlled by controlling the air gap between the conductor rotor and the permanent magnet rotor. [0003] In the field of traditional magnetic coupling design, when the machining accuracy is relatively high between the copper plate and the mounting plate, there is a gap between the copper plate and th...
