Abstract
The invention aims to solve the problems that mounting and debugging are difficult due to mechanical connection of a mechanical coupler or a driving connector in the prior art and particularly, vibration and the like are easily caused under the condition of poor mounting coaxiality, and provides a non-contact type magnetic driving connector. The magnetic driving connector comprises a power device, a driving magnetic ring and a driven magnetic ring, wherein a gap between the driving magnetic ring and the driven magnetic ring can be adjusted, and non-contact transfer of motion is realized through a magnetic action.
Description
Technical field
The present invention relates to mechanical transmission fields, particularly a kind of magnetic transmission connector.
Background technology
Spring coupling (drive coupling) uses parallel or helical cutting system to adapt to various deviation and accurate transfer moment of torsion.Spring coupling mainly contains following two basic series: spiral flute type and parallel groove type.
Spiral flute type spring coupling has the long grooving of a continuous print multi-turn, be suitable for correcting drift angle and axial deviation, but the eccentric ability of process is poor, because will helicla flute be bent in two different directions simultaneously, very large internal pressure can be produced, thus cause the premature breakdown of shaft coupling.Although long spiral flute type shaft coupling can bend easily bearing in various deviation situation, also there is same impact when torsional load to the rigidity of shaft coupling.Revolution gap excessive under torsional load can affect the precision of shaft coupling and weaken the performance of its entirety.
Parallel groove type spring coupling has 3-5 grooving usually, deals with low moment of torsion stiff problem with this.Parallel groove type take into account not weaken when bearing correction of deviation ability and grooving is shortened, and short grooving can make the moment of torsion rigidity reinforced of shaft coupling and overlap on together, enables it bear sizable moment of torsion.This performance makes it be applicable to the application of light load.But this performance is along with the increase of grooving size, and its bearing load also can strengthen.
Simultaneously, above two kinds of spring couplings are owing to adopting mechanical connection, and drive part exists with loading section coupling, particularly in some occasions responsive to vibrations, may be there is the situation of resonance in drive part and loading section, this adds the difficulty of the installation and debugging of equipment undoubtedly.
Summary of the invention
