Abstract
A non-contact no-load power transmission device which can transmit power in a non-contact no-load state by using a magnetic-to-nonmagnetic structure. For this purpose, provided is a non-contact no-load power transmission device characterized by operating in a non-contact manner and comprising: a first disc unit 10 coupled to one of a power shaft or a load shaft and having a magnetic body on one side surface; and a second disc unit 20 coupled to the power shaft or the load shaft that corresponds to the first disc unit 10 and formed of a non-magnetized body that attracts the magnetic body.

A non-contact no-load power transmission device consisting of a power shaft and a load shaft,
- characterized by operating in a non-contact manner and comprising:
- a first disc unit coupled to one of a power shaft or a load shaft and having a magnetic body on one side surface;
- and a second disc unit coupled to the power shaft or the load shaft that corresponds to the first disc unit and formed of a non-magnetized body that exerts an attractive force on the magnetic body,
- wherein:
- the first disk unit comprises a first disk, the magnetic body that is radially disposed and coupled on one side of the first disk, a magnetic force forming plate that is in contact with one side of the magnetic body, and a magnetic force forming fastening member that fastens and binds the magnetic body to the first disk,
- wherein:
- the first disk is further formed with a heat radiation hole for releasing hot air generated by eddy currents generated in accordance with the rotation of the magnetic body and the change in polarity.
A non-contact no-load power transmission device consisting of a power shaft and a load shaft,
- characterized by operating in a non-contact manner and comprising:
