Embodiment 1

[0035] The heat-dissipating coating is obtained by mixing 22kg of phenolic resin, 35kg of aluminum nitride, 8kg of modified silane coupling agent, 5kg of nano-calcium carbonate, and 0.5kg of zinc stearate. The prepared heat dissipation paint was sprayed on the dust cover by electrostatic spraying method to form a heat dissipation coating with a thickness of 30 μm, and the prepared dust cover with heat dissipation effect was used as the protective cover of the electromagnetic clutch.

Embodiment 2

[0037]The heat-dissipating coating is obtained by mixing 25kg of phenolic resin, 38kg of aluminum nitride, 8kg of modified silane coupling agent, 5kg of nano-calcium carbonate, and 0.5kg of barium stearate. The prepared heat dissipation paint was sprayed on the dust cover by electrostatic spraying method to form a heat dissipation coating with a thickness of 30 μm, and the prepared dust cover with heat dissipation effect was used as the protective cover of the electromagnetic clutch.

Embodiment 3

[0039] The heat-dissipating paint is obtained by mixing 28kg of phenolic resin, 40kg of aluminum nitride, 10kg of modified silane coupling agent, 5kg of nano-calcium carbonate, and 0.8kg of zinc stearate. The prepared heat dissipation paint was sprayed on the dust cover by electrostatic spraying method to form a heat dissipation coating with a thickness of 30 μm, and the prepared dust cover with heat dissipation effect was used as the protective cover of the electromagnetic clutch.

Abstract

The invention discloses a high-performance permanent magnet bistable electromagnetic clutch, which relates to the technical field of electromagnetic clutches, and comprises a dust cover and an electromagnetic clutch arranged in the dust cover, the surface of the dust cover is provided with a heat dissipation coating, and the heat dissipation coating is formed by electrostatic spraying of heat dissipation paint. The heat dissipation paint prepared by the invention belongs to powder paint, does not contain an organic solvent, and is easy to store and convenient to spray; the components of the heat dissipation paint are simple, and the burdening workload is reduced while the processing cost is reduced; and the aluminum nitride serves as a heat conduction component of the heat dissipation paint, the characteristic that the aluminum nitride is high in heat conductivity is used for guaranteeing the heat dissipation effect of the dust cover, the dust cover does not affect heat dissipation ofthe electromagnetic clutch while achieving the dustproof effect on the electromagnetic clutch, and normal work of the electromagnetic clutch is guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of electromagnetic clutches, in particular to a high-performance permanent magnet bistable electromagnetic clutch. Background technique: [0002] Electromagnetic clutch, also known as electromagnetic coupling, uses the principle of electromagnetic induction and the friction between the inner and outer friction plates to make the two rotating parts in the mechanical transmission system, and the driven part does not stop rotating when the active part does not stop rotating. An electromechanical connector that can be combined or separated from it, is an electrical appliance that performs automatically. Electromagnetic clutches can be used to control mechanical starting, reverse, speed regulation and braking, etc. It has the advantages of simple structure, fast action, small control energy, and convenient long-distance control; although it is small in size, it can transmit large torque; when used for braking c...
