A contactless electromagnetic clutch

Abstract

A non-contact electromagnetic clutch includes a driving part, a driven part, and a brush power supply part. The active part includes a power shaft connection plate connected to the prime mover shaft, a first iron core, and a first wire. The driven part includes a drive shaft connection plate connected to the drive shaft, a second iron core, and a second wire. The brush power supply part includes a dynamic brush fixedly connected to the connection plate of the power shaft, the dynamic brush is in contact with a fixedly installed electrostatic brush, the electrostatic brush is connected to an external power source, and the current is transmitted to the dynamic brush through the electrostatic brush. The non-contact electromagnetic clutch of the present invention overcomes the mechanical contact wear of traditional clutches, so it is especially suitable for high-speed rotation and poor heat dissipation conditions. It not only greatly improves the service life of the clutch, but also expands the use range of the clutch.

Description

technical field [0001] The invention relates to a non-contact electromagnetic clutch, which is used for connecting a driving device and a driven device. Background technique [0002] The electromagnetic clutch is mainly used to transfer the power of the power machine to the driven shaft of the driven part in the form of a switch, so as to drive the driven part 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, not only will wear and tear occur, but also a large amount of heat will be emitted. 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. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a n...
