Abstract
The utility model discloses a novel elastic coupler which comprises an outer hub wheel, an inner hub wheel, a key groove, steel wire ropes, clamping plates, a fixing bolt, a power output end connecting hole and elastic materials. According to the novel elastic coupler, the inner surface of the outer hub wheel and the outer surface of the inner hub wheel are machined to be in a regular-polygon shape. A wide-band vibration isolator is arranged on each side. Each vibration isolator comprises macromolecule elastic materials, a clamping plate and a steel wire rope. The vibration isolators are fixed on the outer hub wheel and the inner hub wheel through bolts. The key groove connected with a transmission shaft is formed in the inner hub wheel. An opening hole connected with a power output end is formed in the outer hub wheel. The novel elastic coupler has the advantages of being simple in structure, novel in design and capable of reducing shafting torsional vibration effectively and enhancing shafting shock resistance, shafting stable operation is guaranteed, and the safety and the reliability of a power device are improved.
Description
Technical field
The utility model relates to a kind of elastic coupling flexible coupling, belongs to noise reduction technology field.
Background technique
In power plant and power output system, conventionally install coupling additional at clutch end and coupling of shaft system end, coupling adopts elastic element, thereby reduce the special circumstances such as power plant start, acceleration suddenly and cause that axle is the impact to power plant, and reduce the torsional vibration of axle system, guarantee that axle is smooth working, improve the vitality of power plant.At present, the elastic element of coupling adopts single rubber material conventionally, and the easy ageing failure of rubber material and not oil resistant bring risk to power plant.
Summary of the invention
In view of the defect that prior art exists, the utility model provides a kind of New Model of Flexible Coupling.The internal surface of the outer hub wheel of coupling and the outer surface of interior hub wheel are processed into regular polygon, and multiple wide band vibration isolators are installed between described outer hub wheel and interior hub wheel, and vibration isolator is bolted outside on hub wheel and interior hub wheel; On interior hub wheel, have the keyway being connected with transmission shaft, on outer hub wheel, have the perforate being connected with clutch end.
Principle of the present utility model and beneficial effect: New Model of Flexible Coupling simple in structure, novel in design, rely on the interior friction between friction and the macromolecule between Steel Wire Strand to consume torsional vibration of shafting and impact energy, can effectively reduce the torsional vibration of axle system, having excellent anti-axle is to power plant impact capacity, guarantee the smooth operation of axle system, improve the safety and reliability of power plant.
