Abstract
For the metal-rubber interlayer vibration damping structure that aeroengine sensor is installed, comprise sensor, metal-rubber damping pad A, support, metal-rubber damping pad B, pressing plate, bolt, nut are installed; Wherein: sensor lower surface is pressed on metal-rubber damping pad A, on the rack-mount surface of metal-rubber damping pad A, metal-rubber damping pad B is on support lower surface; 4 bolts, successively through sensor, metal-rubber damping pad A, support, metal-rubber damping pad B, are connected with nut, with the compression of installing pressing plate.Advantage of the present utility model: there is high temperature resistant, that the life-span is long advantage, be applicable to the working environment that aeroengine is severe.The part single-piece quantity of sensor support structure reduces, and facilitates the installation Sum decomposition of sensor, improves the efficiency of assembling of aeroengine exterior part.Structure is simple, and assembling is decomposed convenient, effectively can isolate the low-and high-frequency vibration that motor complete machine produces.
Description
Technical field
The utility model relates to aeroengine field, particularly a kind of metal-rubber interlayer vibration damping structure installed for aeroengine sensor.
Background technique
Aeroengine work under bad environment, complete machine oscillation bad environments, along with various high frequency, low-frequency vibration, aeroengine is provided with the annex of some, sensor, require high to vibration environment, thus the support vibration damping structure design of annex, sensor a kind of be all the design difficulty of aeroengine external support structure.
The various sensor constructions that aeroengine is installed are accurate, require very high, need if desired to be designed with vibration damping structure, for the isolation that sensor transmits global vibration of engine in supporting structure to vibration environment.At present, the structure that the sensor that aeroengine is installed mainly adopts support to transfer is connected with motor, be provided with damping pad between support and engine crankcase or between support and sensor, damping pad many employings rubber material, for the vibration isolation between sensor and motor.Existing structure mounting parts quantity is many, and operation splitting loaded down with trivial details inconvenience installed by sensor, and the damping pad of rubber material exists easy aging, non-refractory, life-span short shortcoming simultaneously.
Model utility content
The purpose of this utility model is the deficiency overcoming the existence of existing sensor fixing structure, and spy provides a kind of metal-rubber interlayer vibration damping structure installed for aeroengine sensor.
The utility model provides a kind of metal-rubber interlayer vibration damping structure installed for aeroengine sensor, it is characterized in that: the described metal-rubber interlayer vibration damping structure installed for aeroengine sensor, comprise sensor 1, metal-rubber damping pad A2, support 3, metal-rubber damping pad B4, pressing plate 5, bolt 6, nut 7 are installed;
Wherein: sensor 1 lower surface is pressed on metal-rubber damping pad A2, metal-rubber damping pad A2 is arranged on support 3 upper surface, and metal-rubber damping pad B4 is on support 3 lower surface; 4 bolts 6, successively through sensor 1, metal-rubber damping pad A2, support 3, metal-rubber damping pad B4, are connected with nut 7, with the compression of installing pressing plate 5.
Described support 3 is planar or L shaped plate shape structure.
Advantage of the present utility model:
By adopting the sandwich structure between metal-rubber damping pad and support, at sensor installation direction, there is good damping capacity, metal-rubber maintains good elasticity simultaneously, has high temperature resistant, that the life-span is long advantage, is applicable to the working environment that aeroengine is severe.In addition, adopt the design of integrated combination part between metal-rubber damping pad and sensor, the part single-piece quantity of sensor support structure reduces, and facilitates the installation Sum decomposition of sensor, improves the efficiency of assembling of aeroengine exterior part.This structure is simple, and assembling is decomposed convenient, effectively can isolate the low-and high-frequency vibration that motor complete machine produces.
