Description

A kind of structure for preventing heat from conducting to damper
Technical field
The utility model relates to a kind of structures that prevention heat is conducted to damper, belong to heat-insulating technique field.
Background technique
Aircraft is in high-speed flight, and because of the friction with air, a large amount of thermal energy can be generated on rudder face, leads to rudder face temperature It sharply increases, if can not be shield heat away outside steering engine storehouse, heat will be transmitted to inside steering engine by rudderpost.This is just right The heat resistance of steering engine various components inside proposes very high requirement.The damper of steering engine is usually matched with afterbody output shaft It closes, operating temperature is generally at 300 DEG C hereinafter, if it exceeds operating temperature, damper will fail.So needing in output shaft One heat-proof device is installed between damper, in the range of so that the temperature of damper is maintained at and can be worked normally, and two Person can be with precision-fit.The single heat-barrier material that the prior art uses, such as glass fibre, asbestos etc. can not carry out precision machinery and add Work, and it is easy to produce fifth wheel, it is unable to satisfy use condition.
Utility model content
The purpose of this utility model is to provide a kind of structures that prevention heat is conducted to damper, to ensure damper temperature Degree is maintained in the range of normal work, and has good intensity and processability, while ensuring insulating assembly and damping The precision-fit of device;It prevents insulating assembly from generating fifth wheel at work and influences the normal running conditions of damper, thus gram Take the deficiencies in the prior art.
To achieve the above objectives, the present invention adopts the following technical solutions:
The structure that a kind of prevention heat of the utility model is conducted to damper, including damper and output shaft, damper It is connected with exporting axis by insulating assembly, insulating assembly is made of pressure ring and heat insulation loop, and pressure ring inner headed face and damper cooperation connect It connects, the inner circle and pressure ring outer circle of heat insulation loop are cooperatively connected, and the outer circle of heat insulation loop is connect with output shaft inner hole.
Above-mentioned pressure ring and heat insulation loop are coaxial.
The mounting hole being uniformly distributed along the circumference is equipped on above-mentioned pressure ring and heat insulation loop, screw passes through mounting hole for pressure ring respectively It is respectively fixedly connected on damper and output shaft with heat insulation loop.
By adopting the above-described technical solution, the utility model is compared with prior art, the utility model using pressure ring and This special composite structure of heat insulation loop, and use thermal coefficient for 0.3W/m DEG C, the high-intensitive material that heat resisting temperature is 450 DEG C Heat insulation loop is made in material, and pressure ring is made using the lower high strength titanium alloy material of thermal coefficient, is ensuring the holding of damper temperature In the case where in the range of normal work, heat insulation loop and pressure ring have good intensity and processability, it can be ensured that every The precision-fit of hot component and damper;And prevent heat insulation loop and pressure ring from generating fifth wheel when working, influence the normal of damper Operating condition.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the appearance diagram of the utility model;
Fig. 3 is attachment structure schematic diagram when the utility model is used.
It is marked in figure as follows: 1- heat insulation loop, 2- pressure ring, 3- mounting hole, 4- damper, 5- output shaft, 6- screw.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
The utility model is to be constituted according to a kind of following prevention heats to the method that damper conducts, such as Fig. 1 and Shown in Fig. 2: this method is to install to be made of pressure ring 2 and heat insulation loop 1 on the output shaft 5 for the afterbody connecting with damper 4 Insulating assembly;By the transmitting of insulating assembly trap heat, the temperature of damper 4 is made to be maintained at the range that can be worked normally It is interior;Heat insulation loop 1 uses thermal coefficient for 0.3W/m DEG C, and heat resisting temperature is made of 450 DEG C of high-strength material;It is heat-insulated when production Ring is made preferably with polytetrafluoroethylene material in the prior art;Pressure ring 2 uses the lower existing titanium of thermal coefficient Alloy material is made, and can make pressure ring 2 that there is enough intensity to bear the shearing that damper 4 at work applies pressure ring 2 in this way Power.
The structure that a kind of prevention heat of the utility model constituted according to the above method is conducted to damper, such as Fig. 3 institute Show, including damper in the prior art 4 and output shaft 5, damper 4 is connect by insulating assembly with output shaft 5, insulating assembly It is made of pressure ring 2 and heat insulation loop 1,2 inner headed face of pressure ring and damper 4 are cooperatively connected, and inner circle and 2 outer circle of pressure ring of heat insulation loop 1 are matched Connection is closed, the outer circle of heat insulation loop 1 is connect with 5 inner hole of output shaft;When production, keep pressure ring 2 and heat insulation loop 1 coaxial;Exist simultaneously It is equipped with the mounting hole 3 being uniformly distributed along the circumference on pressure ring 2 and heat insulation loop 1, makes screw 6 respectively by mounting hole 3 by pressure ring 2 and heat-insulated Ring 1 is respectively fixedly connected on damper 4 and output shaft 5.
Embodiment
Heat-proof device is made of heat insulation loop 2 and pressure ring 1.2 periphery of heat insulation loop and output shaft cooperate, the thermally conductive system of material therefor Number is very low, and only 0.3W/m DEG C, heat resisting temperature can carry out precision machinery processing up to 450 DEG C, mechanical strength with higher, It is set to keep preferable concentricity with output shaft.The material that pressure ring 1 uses is titanium alloy, other metals of thermal conductivity ratio are low, Pressure ring inner headed face and damper cooperate, and circumferentially have a mounting hole, and when use is fixed on pressure ring and heat insulation loop on output shaft with screw, It can guarantee that pressure ring and damper have preferable concentricity, and there is enough intensity to apply when bearing damper work to it Shearing force.
This example is applied in combination by heat insulation loop 2 and pressure ring 1, realizes heat-insulated and precision positioning functional requirement, barrier The transmitting of heat, in the range of making the temperature of damper be maintained at and can work normally.Structure is simple, easily fabricated and installation.
