Life reduces, and even causes the major accident of fatal crass time serious.And in practical situations both, outside exciting force be uncontrollable or
Change, owing to tradition shaft coupling does not the most possess the adjustability of elasticity, the most how by changing the characteristic of shaft coupling
The natural frequency of vibration regulating axle system is a kind of good developing direction.
Summary of the invention
The utility model proposes one and utilize the interconnective non-contact type coupling of magnetic force.
This utility model one non-contact type coupling, including driving shaft and driven shaft, described driving shaft and driven shaft it
Between by magnetic force be connected.
Preferably, driving shaft includes respectively that with driven shaft is coaxially disposed and interfixes the axle sleeve and wheel being connected
Dish, wherein wheel disc sets several wheel disc teeth away from a side ring of axle sleeve, and the both sides of each wheel disc teeth are equipped with polarity not
Same magnetic block, on described same wheel disc, the magnetic block magnetic between adjacent two teeth is different;Phase between driving shaft with driven shaft
Engagement arranges formation engagement interval mutually, and in described engagement interval, the magnetic block polarity between the most adjacent two teeth is identical.
Preferably, being arranged on wheel disc of described wheel disc teeth releasable.
It is further preferred that the side that described wheel disc is provided with wheel disc teeth is provided with several dovetail grooves, described dovetail groove
Quantity is consistent with the quantity of wheel disc teeth, and the bottom of each roulette teeth is equipped with the ladder matched with dove tail shape
Shape structure, wheel disc teeth are inserted in dovetail groove by trapezium structure.
It is further preferred that the both sides of described wheel disc teeth are equipped with groove, magnetic block is arranged on the recessed of wheel disc teeth
In groove.

Detailed description of the invention
Embodiment 1.
This utility model one non-contact type coupling, equal including driving shaft 1 and driven shaft 8, driving shaft 1 and driven shaft 8
Include that one group is coaxially disposed and interfixes connected axle sleeve and wheel disc 2 respectively, if wherein wheel disc 2 sets away from a side ring of axle sleeve
Dry wheel disc teeth 3, the both sides of each wheel disc teeth 3 are equipped with the different magnetic block of polarity 4, adjacent on described same wheel disc
Magnetic block magnetic difference 7 between two teeth;Engage each other between driving shaft 1 with driven shaft 8 to arrange to be formed and engage interval 5, institute
State the magnetic block polarity identical 6 between the most adjacent two teeth in engagement interval.Magnetic block 4 described in the utility model is that neodymium iron boron is dilute
Soil permanent magnets.Wheel disc 2 described in the utility model and wheel disc teeth 3 are aluminum wheel disc and aluminum wheel disc teeth or copper wheel dish and copper wheel dish tooth
Tooth.
Non-contact type coupling described in the utility model magnetisable material magnetic between adjacent two teeth on same wheel disc 2
Different;Engage the polarity identical 6 between the most adjacent two teeth in interval 5, it is ensured that between interval 5 every pair of adjacent two teeth of engagement
All by repulsive force, each wheel disc teeth 3 both sides is by captivation.
When two wheel discs 2 are meshed, on driving shaft 1 wheel disc 2, the both sides of teeth are all by phase adjacent teeth on driven shaft 8 wheel disc 2
Repulsive force, when two axles are static, the repulsive force that in engagement interval 5, the most adjacent two teeth are subject to is equal, each wheel disc teeth 3 both sides
The captivation being subject to is equal, and shaft coupling is in stress balance state.When driving shaft 1 rotates to side, engagement interval 5 adjacent two
Gap between wheel disc teeth 3 is gradually reduced, and is affected by magnetic block 4 in wheel disc teeth 3, driving shaft 1 and the teeth of driven shaft 8
Between repulsive force increase therewith, when this repulsive force reaches to be enough to promote driven shaft 8 to rotate, driven shaft 8 start rotate, and by
Gradually accelerate, until dynamic equilibrium.
