Abstract

The present invention provided a drive unit utilizing magnetism which generates high torque and increases torque without enlarging the diameters of a driving magnetic wheel and a driven magnetic wheel. This driving unit, which rotates a shaft b to which a roller is attached by a power transmission mechanism in noncontact making use of magnetic force, transmits power from the driving magnetic wheel 1 to the driven magnetic wheel 2 to which the roller shaft b is attached, by means of two or more transmission systems, and totals the power to rotate the shaft to which the above roller is attached.

Description

technical field [0001] The present invention relates to a driving device that transmits rotational driving force in a non-contact state by using a magnetic wheel. Background technique [0002] In machine tools, industrial machines, etc., a drive transmission device using gears is generally used as a mechanism for transmitting rotational force. However, a drive transmission device using gears meshes with each other to transmit rotational force, which may cause damage due to large torsional force, impact, etc. in addition to tooth surface wear, dust generation, and noise. [0003] Therefore, in order to solve the problems of the above-mentioned driving device using gears, a driving device using a magnetic wheel that transmits rotational force in a non-contact state has been proposed. [0004] In this driving device using a magnetic wheel, the driven magnetic wheel (N poles and S poles are alternately arranged along the circumferential direction) is placed in a non-contact sta...
