Model utility content
The utility model is in order to reduce the deadweight of shock insulation apparatus, provide a kind of base inner wall variable curvature bus vibration isolator, cancel straight reed, bending spring sheet and fixed structure thereof, the general components such as trip ring, conical ring, cushion cover and lower ring, under the requirement meeting vibration isolator electrical property reliability and mutative damp characteristic, alleviate the deadweight of vibration isolator.
The utility model take base as body frame, base plate is fixed on bottom base inner circle, upper cover is fixed on the top of base, the shell of common this vibration isolator of composition, an adjusting bolt is inserted with in upper cover, in adjusting bolt, cover has hexagonal circle, cap, adjusting nut successively from top to bottom, is connected with spiral spring between adjusting nut and base; The top of cap is positioned at outside base, and cap bottom has the shaft shoulder, and the shaft shoulder stretches in base, it is characterized in that: in the outer rim of cap, between upper cover to the shaft shoulder, cover has upper rubber pad, adjustment sleeve and conical ring successively; Described base inner wall is curved surface, is inwardly horizontally disposed with folding ring in the middle part of curved surface, and folding ring outer rim has the tapering that coincide with the outer rim of conical ring and contacts with it, conical ring and folding ring be respectively equipped with the first pad and the second pad up and down.Wherein base inner wall curved surface with the build-up curve of former bending spring sheet, straight reed curved surface for bus.
The utility model cancels former GWF type damping buffer assembly, utilize bent bus base inner wall to replace former straight reed, bending spring chip architecture, and the earth decreases assembling and the debug time of damping buffer assembly, and alleviate weight, completely eliminate the malfunctioning and failure of removal of the vibration isolator caused because of reed permanent deformation.
Further improvement, in described cap outer rim, overlaps between the second pad and the cap shaft shoulder and has belleville spring, be provided with the 3rd pad between belleville spring top and the second pad, be provided with the 4th pad between belleville spring bottom and the shaft shoulder of cap.
By increasing a belleville spring, the radial deformation space of trip ring, conical ring combination can be increased, thus reach the diameter variable quantity of trip ring external diameter, changing adapting with rigidity curved foot inwall inner diameter, reach mutative damp characteristic requirements.
Alleviate vibration isolator deadweight further, all aluminum alloy material can be adopted with other the non-friction surface component except Adjusting bolt Adjusting screw, pad, conical ring, trip ring and spiral spring in the utility model, by the wearing and tearing wall elastic ring cylinder such as having prevent aluminum alloy base inwall at base inner wall cover, reduce wearing and tearing between adjusting bolt and adjusting nut by being provided with steel-wire screw-socket between adjusting bolt and adjusting nut.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The base inner wall variable curvature bus vibration isolator that the utility model provides as shown in Figure 1, with base 8 for body frame, base plate 18 is fixed on bottom base 8 inner circle, upper cover 6 is fixed on the top of base 8, the shell of common this vibration isolator of composition, be inserted with an adjusting bolt 2 in upper cover 6, in adjusting bolt 2, cover has hexagonal circle 1, cap 3, adjusting nut 5 successively from top to bottom, and adjusting nut 5 is connected with adjusting bolt 2 by pin 4.Spiral spring 17 is connected with between adjusting nut 5 and base 8; The top of cap 3 is positioned at outside base 14, and cap 3 bottom has the shaft shoulder, and the shaft shoulder stretches in base 14, in the outer rim of cap 3 from upper cover 6 to the shaft shoulder successively cover have upper rubber pad 7, adjustment sleeve 9 and conical ring 11; The curved surface that described base 8 inwall is is bus with the build-up curve of former bending spring sheet, straight reed curved surface, folding ring 12 is inwardly horizontally disposed with in the middle part of curved surface, folding ring 12 outer rim has the tapering that coincide with the outer rim of conical ring 11 and contacts with it, conical ring 11 and folding ring 12 be respectively equipped with the first pad 10 and the second pad 13 up and down.
In described cap 3 outer rim, overlap between the second pad 13 and cap 3 shaft shoulder and have belleville spring 15, between belleville spring 15 top and the second pad 13, be provided with the 3rd pad 14, between the shaft shoulder of belleville spring 15 bottom and cap 3, be provided with the 4th pad 16.A belleville spring is increased in the lower back-up ring bottom of former utility model patent " a kind of mutative damp variable rigidity bottom vibration isolator ", the radial deformation space of trip ring, conical ring combination can be increased, thus reach the diameter variable quantity of trip ring external diameter, change with rigidity curved foot inwall inner diameter and adapt, reach mutative damp characteristic requirements.
When requiring further to adopt aluminum alloy material as main components, other non-friction surface component that the utility model patent removes Adjusting bolt Adjusting screw, pad, conical ring, trip ring and spiral spring all can adopt aluminum alloy material.In order to prevent aluminium alloy material grinding abrasion, as shown in Figure 2, base 8 inner wall sleeve such as to have at the wall elastic ring cylinder 20, is provided with steel-wire screw-socket 21 between adjusting bolt 2 and adjusting nut 5, and the basis ensureing working life reduce further the deadweight of vibration isolator.
