Problems solved by technology

However, the general electromagnetic clutch uses the power-on and power-off of the electromagnet to control the contact and disengagement between the friction plates. During the movement, it will not only cause wear and tear, but also emit a large amount of heat.
In actual working conditions, many electromagnetic clutches will be used at high speeds and poor heat dissipation conditions. At this time, the use of traditional electromagnetic clutches will produce a series of adverse effects

Embodiment Construction

[0027] like Figure 1~Figure 5 As shown, a non-contact electromagnetic clutch includes an active part 1 , a driven part 2 , and a brush power supply part 3 . The active part 1 includes a power shaft connection plate 101 connected to the prime mover shaft, a first iron core 102 , and a first wire 104 . The driven part 2 includes a drive shaft connecting plate 201 connected to the drive shaft, a second iron core 202 and a second wire 204 .

[0028] The brush power supply part 3 includes a dynamic brush 301 fixedly connected to the power shaft connecting plate 101 , the dynamic brush 301 is in contact with the fixed electrostatic brush 302 , the electrostatic brush 302 is connected to an external power source 303 , and the current is transmitted through the electrostatic brush 302 to the electric brush 301.

[0029] The plurality of first iron cores 102 are fixedly mounted on the power shaft connecting plate 101 , and the first wires 104 are wound on the plurality of first iron...

Abstract

A non-contact electromagnetic clutch comprises a driving part, a driven part and an electric brush power supply part, wherein the driving part comprises a power shaft connecting disc connected with a prime motor shaft, first iron cores and first leads; the driven part comprises a driving shaft connecting disc connected with a driver shaft, second iron cores and second leads; the electric brush power supply part comprises a moving electric brush fixedly connected onto the power shaft connecting disc, the moving electric brush is contacted with a fixedly mounted static electric brush, the static electric brush is connected with an external power supply, and currents are transmitted to the moving electric brush through the static electric brush. The non-contact electromagnetic clutch overcomes the defect of mechanical contact abrasions to traditional clutches, so that the clutch is particularly applicable to occasions with high-speed rotation and poor cooling conditions, the service life of the clutch is greatly prolonged, and meanwhile, the usage range of the clutch is expanded.

Description

technical field [0001] The present invention is a non-contact electromagnetic clutch for connecting a driving device and a driven device. Background technique [0002] The electromagnetic clutch is mainly used to transmit the power of the power machine to the shaft of the follower that needs to be driven in a switch way to drive the follower to move. However, the general electromagnetic clutch uses the power-on and power-off of the electromagnet to control the contact and disengagement between the friction plates. During the movement, it will not only cause wear and tear, but also emit a lot of heat. In actual working conditions, many electromagnetic clutches will be used at high speeds and with poor heat dissipation conditions. At this time, the use of traditional electromagnetic clutches will have a series of adverse effects. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a non-contact electromagnetic clutch, ...
