Description
Technical field
The invention belongs to damper designs field, and in particular to a kind of damper for preventing from being revealed by temperature shock.
Background technology
Viscous damper is a kind of to interact using resisting medium and damper structure component and produce the original of damping force
Reason design, a kind of passive velocity-dependent damper made, subtract and (shake) shake, during anti-(shaking) structure such as shakes in fields such as military projects
There is application more.Be silicone oil usually using resisting medium, the medium is with viscosity-temperature coefficient is small, stable structure, electrical insulation properties are good
The advantages that, but its thermal coefficient of expansion and gas solubility is larger, surface tension is small, easily produced under high/low temperature temperature shock
On The Problem Of Overpressure, is revealed from damper, so as to influence the performance of damper.
The content of the invention
Goal of the invention：A kind of damper is provided, sealing structure therein can solve the resisting medium silicone oil in damper
The problem revealed after temperature shock is subject to.
Technical solution：It is a kind of prevent by temperature shock reveal damper, including sequentially connected protecgulum, procapsid, after
Housing and rear cover, sealing ring is provided between the front end inner ring surface and damping shaft of procapsid, in the rear end inner ring surface of procapsid
O-shaped rubber seal is installed between back casing, diaphragm is installed between the rear cover and back casing, which is circular bullet
Property material.
The protecgulum is installed on by slotted countersunk flat head screw on the end face of procapsid.
After fillister head screw passes through rear cover, back casing and diaphragm, it is connected with the procapsid.
The damping shaft is installed on by rolling bearing in the internal cavity of damper, in rolling bearing and the axis of damping shaft
Adjust pad is installed between shoulder.
Silicone oil is filled with inside the damper.
The sealing ring provides dynamic sealing, O-shaped rubber seal and diaphragm when damping shaft rotates when damping shaft rotates
Static seal is provided.
When being subject to temperature shock, the middle section of diaphragm can produce the swell increment of portions proximate rear cover or close to back casing
Amount of contraction.
By the movable sealing structure of sealing ring can ensure damping shaft can flexible rotating, pass through the dynamic sealing knot of sealing ring
Structure and O-shaped rubber seal, the static seal structure of diaphragm can ensure damper, and in normal work, resisting medium silicone oil will not
Leak, when damper is subject to temperature shock, diaphragm can produce expansion with the volume change of resisting medium silicone oil
And contraction, so as to ensure that On The Problem Of Overpressure will not be produced in the sealing structure of damper, cause resisting medium silicone oil to leak, shadow
Ring the performance of damper.
Beneficial effect：The invention cleverly make use of expansion and the contraction of diaphragm to adapt to resisting medium silicon in sealing structure
The volume change of oil, has good practical value, is adapted to be promoted and applied in existing viscous damper.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
The present invention is described in further details below.
With reference to figure 1.The damper for preventing from being revealed by temperature shock of the present invention, it includes protecgulum 1, damping shaft 2, sealing ring
3rd, slotted countersunk flat head screw 4, rolling bearing 5, procapsid 6, adjust pad 7, O-shaped rubber seal 8, fillister head screw 9, back casing
10th, rear cover 11, diaphragm 12, silicone oil 13, wherein, damping shaft 2 fills damper knot by 5 circle rotation of rolling bearing, silicone oil 13
Cavity in structure, sealing ring 3 provide dynamic sealing when damping shaft 2 rotates, and O-shaped rubber seal 8 and diaphragm 12 are revolved in damping shaft 3
Static seal is provided when turning, diaphragm 12 can produce the swell increment of portions proximate rear cover 11 or close to back casing when being subject to temperature shock
10 amount of contraction, to adapt to the volume change of resisting medium silicone oil in sealing structure of damper, has larger practical application valency
Value.
