Description
Technical field
The utility model relates to mechanical transmission fields, particularly relates to a kind of high-elastic Overloading protective coupling.
Background technique
At some heavy machinery transmission fields, particularly mining machinery, crushing mechanism, in the unit of ship machinery, due to the power of unit own and moment of torsion very large, simultaneously, because actual conditions is ill-conditioned, great impact load is there is in transmission of power, this impulsive load is much larger than the load rating of unit, in order to protect the visual plants such as prime mover, selecting at coupling, often select high-elastic coupling to absorb the impulsive load of unit, the highly elastic shaft coupling used in the market has sector unit, H type block etc., these high-elastic couplers can absorb the impulsive load of unit all to a certain extent, but be limited by the restriction of elastomeric intensity own, when the larger impulsive load of frequent appearance and Peak torque, elastomer very easily cracks, thus damage inactivation.
Model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of high-elastic Overloading protective coupling.This coupling can when being subject to greater impact load, frequent overload, the safety of available protecting visual plant, self is also not easy to damage simultaneously.
For achieving the above object, a kind of high-elastic Overloading protective coupling disclosed in the utility model, it comprises coaxial the input wheel hub, intermediate connecting sleeve, elastomer and the output hub that arrange, and input wheel hub right-hand member is provided with adpting flange; The left end flange of described adpting flange and intermediate connecting sleeve is bolted; Be provided with through hole in intermediate connecting sleeve, be provided with elastomer construction section and keyway section in through hole, described elastomer is fixedly installed in intermediate connecting sleeve through hole elastomer construction section; The keyway section circumference of through hole is evenly provided with several splines; The left end of output hub is provided with coupling shaft, coupling shaft is provided with elastomer linkage section and spline segment, and the elastomer linkage section of coupling shaft is fixedly connected with elastomer by keyway auxiliary connection; The circumference of the spline segment of coupling shaft is provided with several splines, spline inserts in the spline in intermediate connecting sleeve, and the dual-side of spline and spline leaves buffer gap, and this buffer gap is used for avoiding elastomer overload deformed damaged.
During normal work, intermediate connecting sleeve drives output hub to rotate by elastomer, and when impulsive load exceedes elastomer bearing capacity, distortional elastomer, spline contacts with spline, avoids elastomer to continue deformed damaged.
Further, the size of described buffer gap is according to described elastomeric bearing capacity setting.
Further, described elastomer construction section is arranged on the left end in described through hole, and keyway section is arranged on the right-hand member in through hole; Corresponding with it, described elastomer linkage section is arranged on the left end of described coupling shaft, and spline segment is arranged on the right-hand member of described coupling shaft.
Further, the right-hand member of described output hub is provided with flange plate, and this flange plate and described coupling shaft are made into integration.
The high-elastic Overloading protective coupling of the present invention; by special structural design; external tooth cover and internal tooth half connection add spline overload protecting mechanism; when there is larger impulsive load; first elastomer is deformed to several angle, and time load continues to increase, spline overload protecting mechanism is stressed; counteract the partial load on elastomer, protection elastomer is not damaged.
