Described installation mandrel 1 top is screw thread, and the bottom has gong cutter groove for the polished rod of location usefulness on the base.
Described base plate 8 is provided with perforate and passes in and out with convenient screwdriver, and tubular-shank rivet 7 is connected housing 6 with base plate 8, and screw links to each other with support apparatus by tubular-shank rivet 7.
Described bowl-shape gauze pad 4 is consistent with lower bowl-shape gauze pad 5 shapes, and is compressing by the netted Stainless Steel Wire of high density.
Beneficial effect: part of the present invention is few, simple in structure, owing to adopt highdensity bowl-shape wire gauze pad, the stressed rear resilient of wire gaze self possesses the performance of High Damping Spring.Three-way rigidity of the present invention equates that installation mandrel sideshake amount is little.Vibration isolator axial rigidity in the past causes installation mandrel sideshake amount excessive greater than radial rigidity; Vibration isolator of the present invention has accomplished that with new gauze pad structural type three-way rigidity equates, mandrel sideshake amount is installed has significantly reduced to satisfy the requirement of air environment to aircraft of new generation.Vibration isolator in the past produces the purpose that the dry friction dissipation energy reaches anti-vibration and shock by mounting core axial compression receding metal mesh pad, vibration isolator of the present invention is to rely on the bowl wall of bowl-shape gauze pad to be out of shape the purpose that reaches anti-vibration and shock, and the vibration isolating method of the two exists obviously different with structure.
Description of drawings
Fig. 1 is existing vibration isolator structure schematic representation;
Fig. 2 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done to describe in further detail, see also Fig. 1 to Fig. 2.
As shown in Figure 1, be existing vibration isolator structure schematic representation.Existing wire gauze pad class vibration isolator axial vibration isolation mainly rely on mandrel is installed the base compression up and down the wire gauze pad realize, radially realize vibration isolation by the upper wire gauze pad of mounting core axial compression contracting.Because the difference of compression area causes axial rigidity greater than radial rigidity, installation mandrel sideshake amount is large, has apparent in view shortcoming in engineering is used.Just must increase auxiliary component and will overcome above-mentioned shortcoming, cause the vibration isolator size to strengthen, weight increases.
As shown in Figure 2, be structural representation of the present invention, a kind of wire netting cushion three-way vibration isolating device.The present invention realizes anti-vibration and shock to air environment with two highdensity bowl-shape wire gauze pads as vibration isolation element, has both realized the rigidity requirements such as three-dimensional of vibration isolator, can effectively limit again the sideshake that mandrel is installed.Specifically comprise the equipment connection part that forms by mandrel 1 and supporting base 2 are installed, the basic attachment portion that is formed by housing 6 and base plate 8, also comprise the vibration isolation part, described vibration isolation partly comprises bowl type annulus 3, upper bowl-shape gauze pad 4, lower bowl-shape gauze pad 5, lower bowl of type annulus 9, described upper bowl type annulus 3, upper bowl-shape gauze pad 4, lower bowl-shape gauze pad 5, lower bowl type annulus 9 are fastened between installation mandrel 1 and the supporting base 2 and are installed in the housing 6, installation mandrel 1, supporting base 2 exceed housing 6 upper ends, are used for connecting and support apparatus.
Described installation mandrel 1 top is screw thread, and the bottom has gong cutter groove for the polished rod of location usefulness on the base.
Described base plate 8 is provided with perforate and passes in and out with convenient screwdriver, and tubular-shank rivet 7 is connected housing 6 with base plate 8, and screw links to each other with support apparatus by tubular-shank rivet 7.
Described bowl-shape gauze pad 4 is consistent with lower bowl-shape gauze pad 5 shapes, and is compressing by the netted Stainless Steel Wire of high density.Vibration isolator core part of the present invention is upper bowl-shape gauze pad 4 and lower bowl-shape gauze pad 5, and both sizes are identical, have greater density.When supporting base 2 radial motion, push bowl-shape gauze pad bowl wall by bowl type annulus wall, make the bowl wall of bowl-shape gauze pad deform and reach the purpose of anti-vibration and shock.The effect of bowl type annulus is to increase with the junction of bowl-shape gauze pad bowl wall to amass, and improves lateral rigidity.Existing wire gauze pad class vibration isolator mainly relies on to be installed the direct compressed metal mesh pad of mandrel and realizes anti-vibration and shock to air environment, the present invention is that the i.e. side pressure of bowl wall of bowl wall distortion of the bowl-shape gauze pad of dependence is contracted, a side stretching is realized the anti-vibration and shock to air environment, and the distance of installing between mandrel 1 and the supporting base 2 is changeless, not the compressed metal mesh pad.When air environment with mandrel 1 is installed, the bowl-shape gauze pad extrusion metal silk that deforms up and down when supporting base 2 moves, make relatively slippage between the wire, produce the dry friction large energy that dissipates, reach the purpose of anti-vibration and shock, bowl-shape gauze pad can provide very large damping and can accomplish that three-way rigidity equates.
Vibration isolator in the past produces the purpose that the dry friction dissipation energy reaches anti-vibration and shock by mounting core axial compression receding metal mesh pad, vibration isolator of the present invention is to rely on the bowl wall of bowl-shape gauze pad to be out of shape the purpose that reaches anti-vibration and shock, and the vibration isolating method of the two exists obviously different with structure.
The cavity of vibration isolator in the past in housing filled fully by upper and lower wire gauze pad.This is because gauze pad density is little, has the space between the annular metal silk of gauze pad, and the space diminishes between wire when gauze pad is compressed, produces changing of the relative positions formation dry friction between silk and comes dissipation energy.Vibration isolator of the present invention is owing to adopt the high desnity metal gauze pad, and the space is little between wire, and mainly by the gauze pad distortion, the changing of the relative positions when wire is stretched between silk realizes dissipation energy.Upper and lower bowl-shape gauze pad must leave certain cavity and be out of shape by gauze pad in housing.
As shown in Figure 2, the assembly process of vibration isolator of the present invention is as follows:
Lower bowl of type annulus 9, lower bowl-shape gauze pad 5, upper bowl-shape gauze pad 4, upper bowl type annulus 3 are packed into successively and installed on the mandrel 1, again supporting base 2 is screwed into behind the locating face fasteningly, form insulator.
Insulator is pushed in the housing 6, and supporting base 2 exceeds housing 6 about 10mm.
Part of the present invention is few, simple in structure, owing to adopt highdensity bowl-shape wire gauze pad, the stressed rear resilient of wire gaze self possesses the performance of High Damping Spring.Three-way rigidity of the present invention equates that installation mandrel sideshake amount is little.Vibration isolator axial rigidity in the past causes installation mandrel sideshake amount excessive greater than radial rigidity; Vibration isolator of the present invention has accomplished that with new gauze pad structural type three-way rigidity equates, mandrel sideshake amount is installed has significantly reduced to satisfy the requirement of air environment to aircraft of new generation.Vibration isolator in the past produces the purpose that the dry friction dissipation energy reaches anti-vibration and shock by mounting core axial compression receding metal mesh pad, vibration isolator of the present invention is to rely on the bowl wall of bowl-shape gauze pad to be out of shape the purpose that reaches anti-vibration and shock, and the vibration isolating method of the two exists obviously different with structure.
