Description
Technical field
Basis is novel belongs to vibration damping equipment, is specifically related to a kind of falling-proof type vibration damping equipment.
Background technique
Vibration damping equipment is one group of spring-damping element, is being carried out physical isolation by between vibration insulating system and its carrier installation position, improve vibrated to external world by vibration insulating system, the adaptability of the mechanical environment such as impact.At present, the vibration damping equipment that inertial navigation system adopts generally is made up of two T-shaped rubber damping pads, 1, metallic shim, 2, metal spacing sleeve 4, as shown in Figure 1; Wherein damping mat also can make non-symmetry structure form as shown in Figure 2, to meet system frequency characteristic requirement different on X, Y, Z tri-directions.Vibration damping equipment is generally installed together the complete vibration insulating system of formation one with 4 groups or more groups and inertial navigation system, but because metal spacing sleeve is separated completely with metallic shim, inertial navigation system vibration damping equipment when depositing is in non-installment state, cause easily occurring wrongly installed position, neglected loading part during assembled in situ, losing the problems such as part, particularly for the asymmetric damping mat structure shown in Fig. 2, if exchange the position meeting influential system damping property of rubber damping pad I and rubber damping pad II, therefore need professional and technical personnel and instruct assembling at the scene.
Summary of the invention
This novel object is the defect for prior art, provides a kind of falling-proof type vibration damping equipment.
Basis is novel is achieved in that a kind of falling-proof type vibration damping equipment, comprise: rubber damping pad, metallic shim, inertial navigation system install journal stirrup, metal spacing sleeve, rubber damping pad I, rubber damping pad II and mounting screw, wherein metal spacing sleeve is hollow cylinder shape part, rubber damping pad is provided with outside its cylinder, and inertial navigation system is set outside rubber damping pad journal stirrup is installed, arrange metallic shim on the top of rubber damping pad, mounting screw runs through metal spacing sleeve and is fixedly connected with carrier.
A kind of falling-proof type vibration damping equipment as above, wherein, metallic shim is " convex " font structure, in the preformed hole of hollow, arrange worm structure, and this worm structure thickness is 5mm.
A kind of falling-proof type vibration damping equipment as above, wherein, the height of metal spacing sleeve is 39mm, is provided with the M11 outside thread of long 1.5mm and the step of a long 3.5mm on the top of metal spacing sleeve.
This novel effect is: the vibration damping equipment of the application has assembled with inertial navigation system, stops inertial navigation system vibration damping equipment and in the assembled in situ processes such as test, examination, occurs wrongly installed position, neglected loading part, loses the phenomenons such as part.

Embodiment
As shown in Figure 6, a kind of falling-proof type vibration damping equipment, comprise: rubber damping pad 1, metallic shim 2, inertial navigation system install journal stirrup 3, metal spacing sleeve 4, rubber damping pad I 5, rubber damping pad II 6 and mounting screw 7, wherein metal spacing sleeve 4 is hollow cylinder shape part, rubber damping pad 1 is provided with outside its cylinder, and inertial navigation system is set outside rubber damping pad 1 journal stirrup 3 is installed, arrange metallic shim 2 on the top of rubber damping pad 1, mounting screw 7 runs through metal spacing sleeve 4 and is fixedly connected with carrier 8.
Be metallic shim 2 be as shown in Figure 3 and Figure 4 design worm structure, spacer thickness is increased to 5mm by original 2mm, to ensure that screw thread has certain screwing length.Bottom metallic shim, the screw thread of M11 coordinates with the outside thread on spacing collar, and length is 1.5mm, and unthreaded hole φ 11 plus tolerance control size size, guarantees that the outside thread of spacing collar M11 can screw completely and put in place.
Be illustrated in figure 5 metal spacing sleeve 4 height and be increased to 39mm by original 34mm, devise the M11 outside thread of a segment length 1.5mm and the step of a long 3.5mm, step surface plays position-limiting action when mounted, step surface to the height 32mm of spacing collar bottom surface, and by negative common difference control size size.
Vibration damping equipment is rubber damping unit, and the decrement size of rubber damping pad directly affects the rigidity of vibration damping equipment thus changes its frequency, very large on damping efficiency impact.Time inertial navigation system is arranged on carrier, along with tightening of mounting screw 7, metallic shim finally abuts against on spacing collar limit dais terrace, makes rubber damping pad produce certain decrement.By controlling the tolerance of limit dais terrace face height dimension 32mm on earth, can control rubber damping pad by decrement, make vibration damping equipment meet estimated performance index request.
For improving the assembly process process of vibration damping equipment, processing two planes in the both sides of metallic shim boss, distance 16mm, during easy disassembly, using the tool operations such as spanner.
During use, metal spacing sleeve 4 is seated, road external threads structure after loading inertial navigation system installation journal stirrup by rubber damping pad 1; Then metallic shim 2 is screwed in spacing collar outside thread, until pad internal thread screws completely by spacing collar outside thread.
