Description

Technical Field

[0001] The utility model relates to the technical field of magnetic drives, in particular to a liquid-cooled heat dissipation structure for a conductor disc of a magnetic drive. Background Technique

[0002] A magnetic drive is a new type of transmission device that uses the magnetic field force to achieve non-contact transmission of force and torque. This transmission has excellent output adjustability, light-load starting, vibration isolation and shock absorption functions.

[0003] In the prior art, for example, a permanent magnet magnetic coupler with an improved conductor disc proposed in the patent application number "CN201710324357.9" includes a driving shaft, a flange, a conductor disc, a connecting plate, a transmission disc, a load shaft, a transmission pin, a yoke, a permanent magnet, and an aluminum disc. The conductor disc rotor is the driving end and is connected to the driving shaft. The conductor disc is fixed on the magnetic conductor disc; the conductor disc rotor surrounds the permanent magnet rotor.

[0004] However, in the above patent application, the heat dissipation effect at the conductor disc is not good. When the magnetic drive is running, energy loss will generate heat, resulting in equipment temperature rise. If the temperature is too high, it will reduce or even demagnetize the permanent magnet, affecting its working performance and bringing potential safety hazards to production safety.

The heat dissipation fin protrusions are designed in an arc shape to assist in dissipating heat from the conductor disc.

[0008] Preferably, the heat dissipation fin protrusions are arranged at intervals in a ring shape on the same side of the conductor disc, forming a plurality of concentric circle distributions with the same center on the conductor disc.

[0030] The conductor disk 1 is made of a conductive and non-magnetic material.

[0031] The conductor disk 1 is made of copper or copper alloy.

[0032] Such as Figure 1 , the conductor disk 1 made of copper or copper alloy not only has the characteristics of being conductive and non-magnetic, but also has excellent heat conduction effect, lower cost, and is convenient for popularization and use.
