Technical field
The present invention relates to field of mechanical technique, be specifically related to elastic coupling flexible coupling.
Background technique
Elastic coupling flexible coupling uses parallel or helical cutting system to adapt to various deviation and accurate transfer moment of torsion.Elastic coupling flexible coupling usually possesses good performance and has the advantage in price, and in a lot of stepping, servo-system practical application, elastic coupling flexible coupling is first-selected product.The advantage that integrated design makes elastic coupling flexible coupling achieve zero clearance ground transmitting torque and need not safeguard.Elastic coupling flexible coupling mainly contains following two basic series: spiral flute type and parallel groove type.
The feature of elastic coupling flexible coupling: (1) integrated metal elastic gonosome; (2) zero revolution gaps, can run-in synchronism; (3) elastic reaction compensates radial direction, angle and axial deviation; (4) high moment of torsion rigidity and remarkable sensitivity; (5) identical with turning anticlockwise characteristic clockwise; (6) non-maintaining, oil resistant and corrosion resistance; (7) have aluminum alloy and stainless steel material selective; (8) means of fixation mainly contains jackscrew and clamping two kinds.
Most elastic coupling flexible coupling all makes of aluminum alloy material, the elastic coupling flexible coupling that some producers also provide stainless steel to produce.Stainless steel elastic coupling flexible coupling, except corrosion-resistant, too increases torque capacity and rigidity simultaneously, even can reach and double aluminum alloy like product.But the moment of torsion of this increase and the rigidity quality that can be increased to a certain extent and inertia and offset.Sometimes negative effect also can exceed its advantage, makes user be obliged to go to find the coupling of other form like this.
Along with industrial quarters is to the vibration of power plant, the control overflow impacted more and more is paid close attention to, more and more high development of the situation, existing various types of coupling has exposed its narrow limitation in usability: take polymer rubber as the elastic member that raw material is made, due to the restriction of the physicochemical property of the congenital existence of material itself, have impact on the usability of coupling: heat-conducting property is poor, Environmental Conditions temperature range is narrow, life-span is short, because rubber material fissipation factor is low, be unfavorable for the dynamic response under cutting down axle ties up to critical speed of rotation, corrosion resistance is weak, rubber body should not work under tensile stress state.The rigidity characteristic of the elastic coupling flexible coupling of prior art is substantially all in " sclerosis " type, and axis disalignment causes the compensation ability of axis, radial deflection and axial rake limited, and assembly technology requires high, operation inconvenience.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, the elastic coupling flexible coupling that a kind of structure is simple, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution used in the present invention is: it comprises active hub body, driven hub body, spiral elasticity body, connects firmly mechanism, limits torsional angle device, driving shaft acting flange, driven shaft acting flange, damping shock absorption circle; Described active hub body is set in the periphery of driven hub body; Several spiral elasticity body is provided with between described active hub body inwall and the external wall of driven hub; Described active hub body connects by connecting firmly mechanism with spiral elasticity body with spiral elasticity body, driven hub body; One end of described driven hub body arranges limited torsional angle device, and the other end of driven hub body is connected with driven shaft acting flange; The side of described limit torsional angle device is provided with driving shaft acting flange; The outer wall of described active hub body is provided with damping shock absorption circle; Described damping shock absorption circle is viscous damping fluid shock-absorbing circle.
As preferably, described spiral elasticity body adopts the coiling of some bursts of Stainless Steel Wire twisted wire symmetric type equal pitch spiral methods to form.
As preferably, described active hub body and driven hub surface are provided with etch resistant layer.
When the present invention operates, some strands of Stainless Steel Wires in spiral elasticity body produce bending delayed, and the larger coulomb friction damped kinergety of consumption systems effectively, damping shock absorption circle improves the stationarity of system cloud gray model.
After adopting said structure, the beneficial effect that the present invention produces is: elastic coupling flexible coupling of the present invention, and axially, the compensation ability of radial deflection and axial rake is strong, and shock resistance, interference performance are strong, extend working life, the present invention have structure simple, arrange rationally, the advantage such as fabricating cost is low.
