Abstract
A bidirectional independent rigidity wire mesh vibration isolator comprises a mounting core (1), an upper wire mesh pad (3), a spring (4), a housing (5), a side wire mesh pad (6), a metal core barrel (8) and a lower wire mesh pad (10). The side wire mesh pad (6) is arranged between the housing (5) and the metal core barrel (8); a connecting plate radially protruding is arranged at one end of the mounting core, a top plate is arranged on the circumferential surface of the connecting plate, and the axis of the top plate on the circumferential surface of the connecting plate of the mounting core (1) is parallel to the axis of the mounting core (1), and is mutually vertical to the connecting plate. The horizontal rigidity of the utility model is provided by the side wire mesh pad, the vertical rigidity is provided by the upper wire mesh pad, the lower wire mesh pad and the spring, and the vertical rigidity is completely independent from the horizontal rigidity, thereby meeting the requirement of the mutually independent rigidity in the two directions of the vibration isolator. The connecting plate at one end of the mounting core and the top plate on the circumferential surface of the connecting plate enhance the stability of the mounting core.
Description
Technical field
The present invention relates to the vibration isolation buffering device of Aeronautics and Astronautics field airborne equipment, specifically is a kind of two-way independent rigidity wire gaze vibration isolator.
Background technique
In the aircraft flight process; motor equal power device and outside airflow influence all can produce very big vibration; these vibrations are delivered in the cabin through body; all kinds of airborne equipments are in the harsh vibration environment; have a strong impact on the reliability and the working life of airborne equipment; therefore airborne equipment being installed vibration isolator is the most effective a kind of vibration control method, with guarantee airborne equipment particularly air environment under all kinds of harsh vibration conditions, can bring into play function normally.
Airborne equipment is installed the requirement that three axial vibration isolation are all arranged with vibration isolator, and the vertical of vibration isolator all there are different requirements with the substantially horizontal rigidity Design, existing wire gaze vibration isolator is mainly considered vertical rigidity when design, have following defective in actual use: the rigidity of vibration isolator is mainly provided by two wire gauze pads up and down of its inside, these two wire gauze pads provide the rigidity of Vertical direction and substantially horizontal simultaneously, and the method for adjusting vibration isolator rigidity is to adjust the density of these two wire gauze pads.Because the wire gauze pad provides the rigidity of both direction simultaneously, can cause that the rigidity of vertical and horizontal both direction changes simultaneously after the adjustment wire gauze pad density, for some specific Environmental Conditions, existing vibration isolator just can not meet the demands.
Summary of the invention
The present invention be directed to the novel vibration isolator of the special requirement development of certain aviation airborne equipment, use the wire gaze vibration isolator thereby provide a kind of airborne equipment vibration isolation vertical and that substantially horizontal rigidity can independently be adjusted to install.A kind of two-way independent rigidity wire gaze vibration isolator.
The present invention includes mounting core, catch, last wire gauze pad, spring, shell, side wire gauze pad, base plate, metal-cored tube, tubular-shank rivet and following wire gauze pad.
The inside of shell is by side wire gauze pad and metal-cored tube are installed within outer successively.Mounting core one end passes the circular hole at end plate of outer cover center, in the metal-cored tube endoporus of packing into.Be set with catch and last wire gauze pad at mounting core one end, and the flange brim upper surface applying of last wire gauze pad and mounting core open-mouth end is fitted on a surface of catch with the internal surface of shell.Following wire gaze cushion cover is contained on the spring; Spring is positioned at the shell open-mouth end.The flange brim and the base plate of shell open-mouth end are fixed by tubular-shank rivet.The outer surface of side wire gauze pad and internal surface are fitted with the internal surface of shell and the outer surface of metal-cored tube respectively.
The endoporus of mounting core is a tapped hole; The excircle of ring mounting core one end is fluted; The circumferential surface of the mounting core the other end has the connecting plate that radially protrudes, and orthogonal with it top board is arranged on the outer peripheral surface of this connecting plate; The external diameter of this top board is with the internal diameter of metal-cored tube.The axis of the top board on the connecting plate outer peripheral surface of mounting core and the parallel axes of mounting core, vertical mutually with connecting plate.
Among the present invention, metal-cored tube contacts with side wire gauze pad with mounting core respectively, provides the rigidity of substantially horizontal by side wire gauze pad, and the rigidity of Vertical direction is provided by last wire gauze pad, spring and following wire gauze pad.The wire gauze pad is made by wire gaze, and silk wiry footpath is between 0.05mm～0.3mm.Under identical boundary dimension, by adjust to go up respectively the wire gauze pad, down wire gauze pad and side wire gauze pad silk footpath and density and to adjust the pitch of spring identical through obtaining boundary dimension with silk, and vertically with the substantially horizontal stiffness and damping characteristic series product different with load.By changing profile chi size and carrying out the series product that corresponding internal structure design can obtain different boundary dimension, different-stiffness and different loads by the design's principle.
Because the technological scheme that the present invention takes has obtained following effect:
1. the present invention has increased a side wire gauze pad, the horizontal rigidity of vibration isolator is provided by side wire gauze pad fully, vertical stiffness is provided by last wire gauze pad, following wire gauze pad and spring fully, make the rigidity Design of vertical and substantially horizontal independent fully, satisfied certain type equipment the separate requirement of vibration isolator both direction rigidity requirement.
2. the edge of mounting core lower end surface extends a circular connecting plate respectively up and down, increased area of contact with metal-cored tube, effectively limited the swing of mounting core, the dancing that occurs fully can the abatement apparatus horizontal vibration time for the higher airborne equipment of some center of gravity.
