Description
Technical field
The present invention relates to the structure of a kind of vibroshock, particularly relate to a kind of for long and narrow space, damper structure that protection inertia element damages from vibration or the impact from surrounding environment.
Background technology
Current inertia systematic difference is more and more extensive, and these carriers are to indexs such as the profile of inertia system, size, weight, it is proposed that various requirement. In a lot of situation, it is subject to the restriction of carrier or its space layout, the installation space of inertia system, might not be the geometrical shape of rule.
The Working environment of a lot of carrier is very severe, the inertia system that it uses, it is necessary to carry out rational damping design and inertia system could be allowed to have given play to its due precision level. When inertia system profile is restricted, the anti-vibration design of inertia system often can only carry out in a long and narrow space.
Traditional vibroshock is generally made up of the pad of damping material, spacing collar and a position-limiting action. Generally all need a cylindrical working space. When being applied to inertia system, this cylindrical working space, is extended to the rectangular parallelepiped space that bottom surface is square usually. When such vibroshock is applied in the above-mentioned inertia system with long and narrow assembling space, it is subject to the restriction of long and narrow space narrow limit size, its square bottom surface maximal side that can arrange is too little, and the conventional damper with suitable supporting capacity cannot be selected to carry out the anti-vibration design of whole system.
Goal of the invention
The direct sensitive carrier motion morphology of strap down inertial navigation system, by control algorithm, control carrier is according to set regular movement. When the mechanics Working environment of inertia system is comparatively severe, the precision of inertia system can serious reduce, and even whole inertia system is destroyed, it is necessary to carry out anti-vibration design. When the installation space of inertia system is a long and narrow space, vibroshock of the present invention can play desirable effectiveness in vibration suppression in such an embodiment, to ensure that inertia system works normally in severe Working environment.
Summary of the invention
For a damper structure for long and narrow space, vibration damping is carried out for inertia system, wherein, comprising: screw, two spacing posts, four rubber damping pads, subpanel compositions are installed;
Being processed with three unthreaded holes along the long side direction of long and narrow space in inertia system, middle unthreaded hole is used for the installation screw through inertia system; The unthreaded hole of both sides is used for through spacing post;
Spacing post is inverse-T-shaped structure, and the threaded hole corresponding with in subpanel by the screw thread at its top coordinates, and between the bottom of spacing post and subpanel, is followed successively by rubber damping pad, inertia system, rubber damping pad.
As above for a damper structure for long and narrow space, wherein, the columnar part length of spacing post is strictly specified, and dimensional precision is IT7 level, for retraining rubber damping pad; The bottom of spacing post is designed with the hole of an interior hexagonal, so that what use that instrument ensures between spacing post and subpanel reliable is connected.
Useful effect
The present invention is on the basis fully understanding conventional damper principle of work, proposing a kind of new damper structure form that apply in long and narrow space, that can significantly improve vibroshock supporting capacity, the inertia system being restricted in order to improve some profile bears the ability of severe mechanics Working environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of damper structure for long and narrow space of the present invention;
Fig. 2 is damper structure schematic diagram in prior art.
Wherein, 1 installation screw, 2 inertia systems, 3 spacing posts, 4 rubber damping pads, 5 subpanels, 11 metallic gaskets, 12 rubber pads, 13 metal spacing sleeves.
Specific embodiment
Hereinafter, with specific embodiment, the present invention is described further by reference to the accompanying drawings, a kind of damper structure form for long and narrow space, as shown in Figure 1. It is made up of installation screw 1, inertia system 2, spacing post 3 (two), rubber damping pad 4 (four), subpanel 5. Inertia system 2 is protected parts; The vibration that rubber damper 4 transmits for carrier of decaying, spacing post 3 and subpanel 5 are for limiting the working stroke of rubber damper.
Processing 3 unthreaded holes along the long side direction of long and narrow space in inertia system 2, the load born by vibroshock and vibration level are to determine the geometric parameter of vibroshock rubber cushion, then the geometric parameter according to vibroshock rubber cushion, it is determined that structural unthreaded hole diameter; Middle unthreaded hole is used for installing screw through carrier, and its diameter should be greater than (or equaling) and install the diameter of screw 1 and two vibration damping space, side sum (the vibration damping space, single side in this example is 2mm).
Spacing post 3 is coordinated by the threaded hole that the screw thread at its top is corresponding with in subpanel 5, and the columnar part length of design upper limit post 3 for retraining rubber damping pad 4, is ensured its correct working order by hard constraints (dimensional precision is IT7 level). The bottom of spacing post 3 is designed with the hole of an interior hexagonal, so that what use that instrument ensures between spacing post 3 and subpanel 5 reliable is connected.
Screw 1 is installed and is in use divided into two kinds, a kind of directly selection standard screw, another kind selects self-control dog screw, positioning principle is near the local of screw head at installation screw, coordinating of H7/g6 is adopted with the middle hole of crossing in subpanel 5, positioning, often overlap in inertia system in the vibroshock of the present invention installed, the use quantity of self-control screw must not more than 2 pieces. The design specifications that the middle via diameter basic size of subpanel 5 crosses hole according to general screw performs.
What accompanying drawing 2 provided is the structure formation of common vibroshock, and 11 is metallic gasket; 12 be rubber pad, 13 is metal spacing sleeve. Screw is installed and fixes vibroshock through the hole of crossing in the middle of 11 and 13.Space shared by it is a cylinder shape space.
Vibroshock of the present invention is that the cylinder shape space transforming taken by common vibroshock has become cuboid space, to adapt to the requirement of long and narrow space, mainly reduce bulk: a from two aspects and often organize four rubber pads that vibroshock is become vibroshock of the present invention by two rubber pads of common vibroshock, when carrying capacity is constant, it is possible to significantly reduce the diameter of rubber pad; The spacing structure of b does not need installing diametrically progressively increasing of screw.
When rubber damping pad 4 assembles, when keeping free state, self-control dog screw can ensure that inertia system 2 assembles the uniqueness of position on carrier. The operational vibration of carrier can be directly delivered to installs in screw 1, spacing post 3 and subpanel 5, and the rubber damping pad between spacing post 3, subpanel 5 and inertia system 2 can isolate part vibrational energy, and the vibration energy being delivered in inertia system 2 is reduced. The thickness of subpanel 5 should design by calculating, to guarantee that it has enough rigidity, it is necessary to avoids assembling the problem that distortion occurs under the effect installing screw 1 in rear subpanel 5. Method of calculation are technology between Gongzhi.
The design of vibroshock of the present invention, utilizes long and narrow space to arrange two groups of vibroshocks, effectively improves the supporting capacity of vibroshock, ensure that the Working environment requirement of inertia system.
