Abstract
The utility model relates to a speed-variable rotational transmission mechanism, which comprises a driving wheel and a driven wheel non-coaxially driven by the driving wheel. The speed-variable rotational transmission mechanism is characterized in that: permanent magnets, the magnetic poles of which face outwards, are evenly arranged along the circumferences of the outer rims of the driving wheel and the driven wheel; the arrangement of the outward magnetic poles of the permanent magnets is that the polarities of all the outward magnetic poles are the same or that the outward magnetic poles are arranged in the form of polarity alternation; and part of the permanent magnets on the outer rims of the driving wheel and the driven wheel are close to each other but are not contacted with each other. Compared with the prior art, the speed-variable rotational transmission mechanism has the following advantages: because the parts are not contacted with one another, no friction heat is generated, the transmission parts do not wear down one another, no noise is generated, and rotational transmission can be realized in different directions.
Description
Technical field:
The utility model relates to a kind of transmission mechanism.
Background technology:
General mechanical rotation transmission, particularly speed change transmission generally all is to adopt the contact kinds of drive such as friction pulley, gear, worm and gear, there is following shortcoming in the above-mentioned kind of drive: 1, be easy to generate frictional heating; 2, transmission device produces wearing and tearing in the course of the work; 3, produce noise.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of does not have the part contact, can not produce the rotation drive machine that frictional heating, transmission device do not have a kind of variable-ratio mutual wearing and tearing, that do not have noise at work.
The utility model is to realize like this, the follower that comprises driving wheel, drives by the non-coaxial line of driving wheel, its special feature is that driving wheel, follower outer edge surface upper edge circumference evenly are provided with the outside permanent magnet of magnetic pole, the outside magnetic pole of permanent magnet is arranged and is provided with is such, all identical or outside pole polarity of outside pole polarity are that south, the arctic are provided with at interval, and driving wheel, follower outer edge surface top permanent magnet are close together non-contactly.During work, driving wheel is at actuating unit, the drive of initiative drive shaft is rotated down, permanent magnet on its outer edge surface is also along with rotation, with perpendicular to the permanent magnet on the corresponding follower of the permanent magnet on the driving wheel tangent line under the magneticaction of permanent magnet corresponding on the driving wheel, also along with moving, drive follower also along with driving wheel rotates, because permanent magnet is arranged on driving wheel, on the follower outer edge surface and driving wheel, follower is not on the same axis, therefore, driving wheel, the diameter of follower can be inequality, and, can form certain acute angle mutually and be provided with, like this, not only can not produce frictional heating, transmission device does not have mutual wearing and tearing at work, there is not noise, and, can realize the speed change transmission, and, can change the rotation direction after the transmission.
Here, the mutual balance of axis of the driving wheel rotating shaft of driving wheel, follower, follower rotating shaft, the driving wheel that has a permanent magnet has two or more and is fixed in the same driving wheel rotating shaft, the follower that has permanent magnet that correspondence has the driving wheel of permanent magnet has two or more, and is fixed in the same follower rotating shaft.Adopt two or more driving wheel, follower, can promote the driving force between driving wheel, follower.
The utility model compared with the prior art, have the contact of no part, can not produce frictional heating, transmission device do not have at work mutual wearing and tearing, that do not have noise, can carry out the advantage that different directions rotates transmission.
