specific Embodiment approach

[0017] The specific embodiment: the present invention will be further described below in conjunction with accompanying drawing:

[0018] Double magnetic wheel non-backlash permanent magnet non-contact forward drive device, which includes servo motor 5, transmission unit 4, drive wheel 2 and iron guide rail 1; the drive wheel is connected with the servo motor through the transmission unit, and the circumference of the drive wheel The surface is evenly inlaid with permanent magnet blocks 3, and the iron guide rail 1 is set above the driving wheel 2 and does not contact the driving wheel 2, so that the two can generate the maximum driving force when they are not attracted. The iron guide rail 1 is an iron rack part with a radial section of convex teeth that is arc-shaped and does not have a permanent magnet; when the driving wheel 2 is stationary, the uppermost permanent magnet block 3 is deflected from the position of the convex teeth of the iron guide rail 1 Angle α, this angle...

Abstract

The double magnetic wheel non-backlash permanent magnet non-contact forward driving device is characterized in that the device includes a servo motor, a transmission unit, a driving wheel and an iron guide rail; the driving wheel is connected with the servo motor through the transmission unit as a whole. A new type of drive implementation method and corresponding device structure is proposed to improve drive efficiency, completely eliminate gaps in the transmission chain, reduce operating costs, and save energy and protect the environment. Especially for long-distance transportation, since the guide rail is made of iron and does not contain permanent magnets, it is low cost. The advantages of cost are becoming more and more obvious. At the same time, it provides a new solution for the drive mode of the conveying system in the clean room.

Description

technical field [0001] The invention relates to a double magnetic wheel non-backlash permanent magnet non-contact forward driving device, which belongs to the technical field of electromechanical integration. Background technique [0002] Due to the large transmission ratio of the rack and pinion mechanism, high mechanical efficiency, relatively good rigidity, convenient manufacture, and low price, it is widely used in large-scale machine tools with large strokes. The traditional double-pinion rack transmission has friction. Disadvantages such as oil stains, wear, heat, noise, etc., are not suitable for dust-free, constant temperature, noise-free and other working spaces. And the contact force of the rack and pinion cannot be changed. Magnetic levitation technology has been widely used in various fields of society, and has the advantages of being able to work in dust-free, constant temperature, and noise-free working spaces. There is a magnetic wheel and rack drive in the e...
