Problems solved by technology

[0005] However, in the driving device shown in Patent Document 1, the driving magnet wheel and the driven magnet wheel intersect each other one-to-one, and power is transmitted from one part of the intersection. There is a limit to the transmission torque of the shaft), which is small
Therefore, the driving device is used for conveying lighter items, etc., which is not conducive to the driving device for conveying heavy objects.
[0006] In the above-mentioned driving device, as a method of increasing the torque or increasing the torque, it can be considered to increase the outer diameter of the driving magnet wheel and the driven magnet wheel, but if the diameter of the driving magnet wheel and the driven magnet wheel is increased, Then, of course, the cost will increase, and the overall size of the driving device will also increase. As a result, there will be a problem that the device using the driving device will also increase in size.

Abstract

The present invention provides a driving device using magnetism. The driving device does not increase the diameters of the driving magnetic wheel and the driven magnetic wheel, and does not set another transmission system branched from the driving shaft. On the same axis as the shaft of the moving magnetic wheel, the misalignment limit is increased to realize torque improvement. In the driving device of the present invention, the driven shaft is disposed at right angles to the driven shaft driven by an appropriate driving mechanism, and the power transmission from the driving shaft to the driven shaft is performed by a non-contact power transmission mechanism utilizing magnetic force; wherein, in The driving shaft and the driven shaft are respectively equipped with magnetic wheels that alternately magnetize N poles and S poles in a spiral shape, and magnetic action parts from one magnetic wheel to the other magnetic wheel are provided at multiple positions on the same axis.

Description

technical field [0001] The invention relates to a driving device which utilizes a magnetic wheel to non-contactly transmit a rotary driving force. Background technique [0002] Transmission drive devices using gears as mechanisms for transmitting rotational force are widely used in machine tools and industrial machinery. However, a transmission drive device using gears transmits rotational force by meshing the gears with each other, so there is a risk of damage due to high torque, impact, etc. in addition to tooth surface wear, dust generation, and noise generation. [0003] Therefore, as a solution to the above-mentioned problems of the drive device using gears, a drive device using a magnet wheel that transmits a rotational force in a non-contact state has been proposed. [0004] The driving device using a magnetic wheel is opposite to the driving magnetic wheel that magnetizes the N pole and the S pole in a spiral shape, and makes the axis center of the driven magnetic w...
