Description
Technical field
The utility model relates to a kind of isolation mounting, particularly relates to a kind of suspension type non-resonant vibration isolation device.
Background technique
In current disclosed vibration isolator, except bottom support resonance-free vibration isolator, backing-type resonanceless vibration isolator, in suspension type vibration isolator, also do not occur without resonance.Along with developing rapidly of modern industry, for the antijamming capability of some accurate equipment under the environment such as vibration, impact, acceleration, more and more higher requirement has been proposed, the impact on precision equipment when existing suspension type vibration isolator not can solve resonance.Therefore, for some, need hang the precision equipment of use, need the appearance of new suspension type vibration damper.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of suspension type resonance-free vibration isolator, to solve the resonance problems in traditional suspension type vibration isolator.
The technological scheme that the utility model solves its technical problem employing is: a kind of suspension type resonance-free vibration isolator, comprise suspension core, upper spring seat, lower spring cup, dolioform spring sheet damper, main spring, bottom spring, base, shell, be characterized in: hang core lower end and lower spring cup sliding connection, upper end is threaded with upper spring seat, upper spring seat is connected with the dry friction of dolioform spring sheet damper, between upper spring seat and lower spring cup, be embedded with main spring and bottom spring, and bottom spring is enclosed within and hangs on core, main spring is socketed in outside bottom spring, dolioform spring sheet damper upper end is connected with base with upper conical collar by opening taper collar, base is connected with outer casing screw, fill with wire gaze shell and lower spring cup upper end.
Between opening taper collar and upper conical collar, by the conical surface, be connected.Hanging core lower end is hexagon, and there is a word groove upper spring seat end, has inner hexagonal hole on base.
The beneficial effects of the utility model are:
In the utility model, dolioform spring sheet damper provides the effect of dry-friction damping power, when outside excitation force is less than dry-friction damping power, dry-friction damping power from structure will by vibration isolation object with basis " lock " together with, by vibration isolation object, do not had to produce and basic Relative Vibration, vibration transmissibility is 1; When excitation force is greater than dry-friction damping power, can " release " by vibration isolation object and basis, vibration could continue.Waiting under displacement incentive condition, outside excitation force increases with the increase of energizing frequency, therefore can adjust suitable dry-friction damping power by dolioform spring sheet damper, make by vibration isolation object when the low-frequency excitation by " pinning ", and when high frequency pumping, realize vibration damping, vibrating isolation system vibration transmissibility perseverance in whole vibration processes is not more than 1, realizes without resonance.
In the utility model, can be by the threaded adjustment between adjusting base and shell the dry-friction damping power size of dolioform spring sheet damper, by moving up and down and conical surface effect of whorl of base pair, make opening taper collar convergent-divergent, thereby the upper end that makes dolioform spring sheet damper is tightened up or loosened, adjust dry-friction damping power size.Can also hang by adjusting the pre compressed magnitude of the threaded adjustment main spring between core and upper spring seat, thereby can adjust vibration isolator, when suspension equipment, hang the extending amount of core.
In the utility model, have impact resistance, when having percussion, bottom spring is encountered in upper spring seat lower end, now main spring and bottom spring acting in conjunction, and opposing is impacted.
In the utility model, the ability also with opposing transverse vibration, impact, between lower spring cup and shell, leave gap, with wire gaze, fill, when having transverse vibration, impact, lower spring cup upper end extrusion metal silk screen, dolioform spring sheet has lateral stiffness simultaneously, jointly resists transverse vibration, impact.
Compare with existing suspension type vibration isolator, the utlity model has without resonance, the advantage such as damping is adjustable, pre compressed magnitude is adjustable, shock resistance, played good vibration isolating effect.
Accompanying drawing explanation
Fig. 1 is the main sectional view of structure of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As Fig. 1, shown in 2, a suspension type resonance-free vibration isolator, comprises and hangs core 1, lower spring cup 2, wire gaze 3, main spring 4, bottom spring 5, upper spring seat 6, dolioform spring sheet damper 7, opening taper collar 8, upper conical collar 9, base 10, shell 11.
Hang core 1 lower end and have interior threaded hole, suspension equipment, with lower spring cup 2 sliding connections, be threaded with upper spring seat 6, main spring 4 and bottom spring 5 are embedded in upper and lower spring seat 6,2, bottom spring 5 is enclosed within and hangs on core 1, main spring 4 is socketed in outside bottom spring 5, upper spring seat 6 is connected with dolioform spring sheet damper 7 dry friction, damper 7 upper ends are connected with opening taper collar 8, opening taper collar 8 is connected by the conical surface with upper conical collar 9, and base 10 is threaded with shell 11, and shell 11 is filled with wire gaze 3 with lower spring cup 2 upper ends.
