Abstract
The invention belongs to the technical field of inertia, and relates to a silicone rubber metal shock absorber. The silicone rubber metal shock absorber comprises a movable ring (2), a fixed ring (3), and a silicone rubber (4) filled between the movable ring and the fixed ring. The silicone rubber metal shock absorber is characterized in that tooth-shaped projections (1) are evenly distributed on the movable ring (2) and the fixed ring (3) of the shock absorber at intervals. Under the condition of not changing the physical parameters of the silicone rubber material filled between the movable ring and the fixed ring of the shock absorber, as the tooth-shaped projections are arranged on the movable ring and the fixed ring, the angular movement gap between the movable ring and the fixed ring of the shock absorber is reduced, and the angle rigidity of the shock absorber is improved.
Description
Technical field
The invention belongs to field of inertia technology, relate to a kind of silicone rubber metal damper.
Background technique
Inertia sensing assembly has installed accelerometer and gyro, respectively sensitive line acceleration and angular velocity.Due to accelerometer and gyro measurement error inherently, under vibration, there is measurement error in linear acceleration and the angular velocity of positive and negative alternation, long-term accumulated can be increasing.
Vibration damper can be decayed linearly coupled and angular vibrations after resonant frequency, plays the nonmetallic material such as normally air, liquid, rubber of decay, damping function.The physical parameter adjusting these nonmetallic material can make vibration damper show suitable damping capacity, but only selects a kind of nonmetallic material to be not easy to make vibration damper meet linearly coupled requirement and angular vibrations requirement simultaneously.
Vibration damper is made up of moving-coil, the calmly packing of circle and nonmetallic material, and traditional vibration damper adopts the packing of nitrile rubber as moving-coil and between calmly enclosing.Compared with nitrile rubber, it is wide that silicone rubber has temperature resistant range, aging-resistant advantage, but shortcoming to be damping little.Under Vibration Condition, moving-coil and the fixed moving displacement that encloses and angular displacement large.Adopt the space between the moving-coil of silicon rubber filling vibration damper and fixed circle, the more difficult vibration damper that makes meets linearly coupled requirement and angular vibrations requirement simultaneously.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of silicone rubber metal damper that can improve vibration damper angular rigidity.
Technological scheme of the present invention is: a kind of silicone rubber metal damper, comprise moving-coil 2, surely enclose 3 and fill moving-coil and fixed enclose between silicone rubber 4, it is characterized by: described vibration damper moving-coil 2 and surely on circle 3 respectively setting be uniformly distributed profile of tooth protrusion 1 spaced apart.
The invention has the beneficial effects as follows: silicone rubber metal damper of the present invention is not when needing to change the physical parameter of filling vibration damper moving-coil and the fixed silicone rubber material enclosed, by arranging the profile of tooth protrusion on moving-coil and fixed circle, decrease vibration damper moving-coil and the fixed angular motion gap enclosed, thus improve the angular rigidity of vibration damper.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
See Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of silicone rubber metal damper of the present invention, comprise moving-coil 2, surely enclose 3 and fill moving-coil and fixed enclose between silicone rubber 4, on the moving-coil and fixed circle of described vibration damper, setting is uniformly distributed profile of tooth protrusion 1 spaced apart respectively.
The moving-coil of vibration damper and the inclined-plane of fixed circle increase profile of tooth protrusion, the top of the profile of tooth protrusion wherein on moving-coil and determine gap between circle than there is no the moving-coil of profile of tooth thing and fixed enclose between gap little, by the top of the profile of tooth protrusion on adjustment moving-coil and fixed enclose between gap can adjust the angular rigidity of moving-coil and this profile direction vertical with the spaced winding determining circle.As shown in Figure 5
Equally, gap between the top of the profile of tooth protrusion on fixed circle and moving-coil is little than not having the gap of determining between circle and moving-coil of profile of tooth thing, can be adjusted the angular rigidity determining circle and this profile direction vertical with the spaced winding of moving-coil by top and the gap between moving-coil adjusting the profile of tooth protrusion determined on circle.
On moving-coil and fixed circle, be uniformly distributed multiple profile of tooth protrusion respectively, and the profile of tooth thing on moving-coil is evenly spaced apart mutually with the fixed profile of tooth protrusion enclosed, as shown in Figure 6.The sidepiece of profile of tooth protrusion on fixed circle and the gap between the sidepiece of the profile of tooth protrusion of moving-coil less than there is no the gap of determining between circle and moving-coil of profile of tooth thing, the angular rigidity in the spaced winding vertical bottom face direction of determining circle and moving-coil can be adjusted by the gap between the sidepiece of the profile of tooth protrusion of the sidepiece and moving-coil that adjust the profile of tooth protrusion determined on circle.
The size of profile of tooth protrusion can be adjusted, also can adjust the inclination of the side of profile of tooth protrusion.All adjustment are all to control gap relevant with angular motion between moving-coil with fixed circle, complete the object of adjustment vibration damper angular rigidity by adjusting this gap.
The specific embodiments of the display of the present invention shown in Fig. 1 is a kind of moving-coil and determines the structure that circle respectively has four profile of tooth protrusions.The quantity increasing or reduce profile of tooth protrusion also can reach the object of adjustment vibration damper angular rigidity.
