Abstract
The invention discloses a flexible coupler for a high-speed machine. The flexible coupler comprises two semi coupler units, two connecting plates and an inflating ring; the connecting plates comprise round steel plates and a plurality of cylindrical pins; the inflating ring comprises a hollow rubber ring, a valve core and gas; the round steel plates of the connecting plates are provided with a plurality of rubber injecting holes, the connecting plates are cast in the rubber of two sides of the hollow rubber ring respectively, the outer circumference of the hollow rubber ring is connected to the valve core, the compressed gas inflates into the cavity of the hollow rubber ring, the flexibility of the inflating ring can be adjusted through the pressure, the inflating ring is mounted between the semi coupler units, and the cylindrical pins of the connecting plates are inserted into the holes of the semi coupler units. The flexible coupler has the advantages that the vibration absorption performance is fine, the flexibility is adjustable, and the rotating speed is high.
Description
Technical field
The present invention relates to a kind of flexible coupling in high speed machines.
Background technique
Current known flexible coupling, they adopt spring sheet and the flexible connecting method such as circle, rubber plate and circle, wire rope, canvas, fluid power, this coupling has better anti-seismic performance, be applicable in middling speed machine, but high speed machines (more than 10000 revs/min) is seemed flexible and bit shift compensation not good enough.
Summary of the invention
There is flexible and that bit shift compensation is not good enough deficiency to overcome conventional flex coupling, object of the present invention provides a kind of shock-absorbing good, flexible adjustable flexible coupling.
The present invention's adopted technological scheme of dealing with problems is: it comprises half-coupling, connecting plate, aeration ring, connecting plate comprises round plate, straight pin, aeration ring comprises the hollow rubber band, valve inside, gas, connecting plate is provided with multiple hole for injecting glue by round plate, branched straight pin is evenly connected on round plate and forms, two pieces of connecting plates are cast in the rubber of the hollow rubber band two side respectively, the hollow rubber band cylindrical connects a valve inside, pressed gas injects the hollow rubber band, air pressure adjustable inflatable circle is flexible, aeration ring is contained in the middle of two half-couplings, on connecting plate, straight pin inserts in the hole of half-coupling.When first connection device of driving shaft rotates, go to drive first connection device of driven shaft by aeration ring, form because aeration ring is filled with air pressure by the hollow rubber band, there is fine ductility, the vibrations that all displacements produce can be absorbed, again because the flexibility of aeration ring can regulate with air pressure, thus it is good to reach shock-absorbing of the present invention, flexible adjustable object.
The invention has the beneficial effects as follows, for high speed machines coupling, have shock-absorbing good, flexible adjustable, also just little because shaking little noise.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Figure is the sectional drawing of the embodiment of the present invention.
In figure 1, aeration ring 1-1, the hollow rubber band 1-2, valve inside 1-3, gas 2, connecting plate 2-1 round plate 2-2, straight pin 3, partly join device
Embodiment
In the embodiment shown in figure, aeration ring 1 connects a valve inside 1-2 by the hollow rubber band 1-1 outer ring, and pressed gas 1-3 injects in the hollow rubber band 1-1 chamber and forms, and the hollow rubber band 1-1 can set up mesh skeleton according to requirement of strength.Valve inside 1-2 is spring non-return valve.Gas 1-3 selects nitrogen etc.Air pressure can adjust the flexibility of aeration ring 1.Connecting plate 2 is provided with multiple hole for injecting glue by round plate 2-1, branched straight pin 2-2 evenly and round plate 2-1 connect and compose.Two pieces of connecting plates 2 are cast in the rubber of the hollow rubber band 1-1 bis-side of aeration ring 1, and rubber injects on round plate 2-1 in hole for injecting glue, by connecting plate 2 and rubber fix tightly.The position of straight pin 2-2 on connecting plate 2, on size, quantity and half-coupling 3, the position in hole, size, quantity match, and aeration ring 1 is installed in the middle of two and half devices 3, and straight pin 2-2 inserts in the hole of half connection device 3.Two half-couplings 3, by straight pin 2-2 and aeration ring 1 transmitting torque, have fine ductility.For high speed machines coupling.
Claims (2)
1. a flexible coupling, it comprises half-coupling, connecting plate, aeration ring, connecting plate comprises round plate, straight pin, aeration ring comprises the hollow rubber band, valve inside, gas, it is characterized in that: connecting plate is provided with multiple hole for injecting glue by round plate, branched straight pin is evenly connected on round plate and forms, two pieces of connecting plates are cast in the rubber of the hollow rubber band two side of aeration ring respectively, the hollow rubber band cylindrical connects a valve inside, pressed gas injects in the hollow rubber band chamber, air pressure adjustable inflatable circle is flexible, aeration ring is contained in the middle of two half-couplings, on connecting plate, straight pin inserts in the hole of half-coupling.
