Description
Technical field
The present invention relates to a kind of spring dampers, and in particular to a kind of flat rocker arm formula spring damper.
Background technique
Spring damper is to be usually used in controlling the fluid oscillation excitation of duration by spring shock-absorbing.Spring shock-absorbing can be with
Filtering vibration, but spring itself also has reciprocating motion, and spring fatigue is caused to damage, and existing spring damper is in spring breaking down
Entire damper needs to remove replacement or maintenance afterwards, this just brings the disassembly to equipment, this disassembly in many cases due to
It is not to be carried out under the assembling environment of manufacturer, when will lead to and destroyed to the stealth of equipment, and disassembling and installing consuming
Between it is long.
Summary of the invention
It it is an object of the invention to overcome defect of the existing technology, provides a kind of easy to maintenance, is not necessarily to integral demounting
Flat rocker arm formula spring damper.
In order to achieve the above objectives, the technical scheme adopted by the invention is that: a kind of flat rocker arm formula spring damper, including
A piece elastic axis, elastic axis are made of guideway and the guiding axis being mounted in guideway, respectively set at the both ends of elastic axis
A rocker arm fixed plate and connecting bushing are set, connects two between two rocker arm fixed plates with the axisymmetric rocker arm of damping,
Spring(-supported) mount is respectively set in the hinged place of two rocker arms, and spring one end is mounted on spring(-supported) mount, and the other end of spring passes through pressure spring machine
Structure connection, when elastic axis is pressurized, direction compressed spring of the rocker arm hinged place to separate guideway.
Further, the rocker arm is made of two hinged rocking bars in centre, the other end of two rocking bars respectively with two
Rocker arm fixed plate is hinged, and two rocker arms constitute plane quadrilateral.
Further, the material of several springs is identical with size.
Further, the elastic axis is hydraulic stem, and guideway is cylinder body, and guiding axis is piston rod.
Further, the spring(-supported) mount is bar or plate with several spring fixing grooves, and it is solid that spring one end is mounted on spring
Determine in slot；Pressure spring mechanism includes the bracing wire an of pressure spring plate and connection pressure spring plate, is drawstring through among spring, makes pressure spring plate and bullet
The connection of the spring other end.
Further, the bracing wire mounting of the pressure spring mechanism on two rocker arms, and spring and pressure spring machine on spring(-supported) mount
Structure is even number setting, and is located at elastic axis two sides and is symmetrical arranged.
The method have the benefit that: it, will be along the power part of elastic axis point by two rocker arms and spring assembly
Solution reduces the pressure to elastic axis at the power normal thereto on spring, extends its service life, and damping effect is more
It is good；In single spring breaking down, replacement only need to be taken down, without dismantling entire damper.
Detailed description of the invention
The present invention is further elaborated with embodiment with reference to the accompanying drawing.
Fig. 1: for structural schematic diagram of the invention.
In figure: 1, connecting bushing, 2, rocker arm fixed plate, 3, elastic axis, 31, guideway, 32, guiding axis, 4, rocker arm, 5,
Spring(-supported) mount, 6, spring, 7, pressure spring mechanism.
Specific embodiment
Embodiment 1
A kind of flat rocker arm formula spring damper, including an elastic axis 3, elastic axis 3 is by guideway 31 and is mounted on guiding
Guiding axis 32 in axle sleeve is constituted, and a rocker arm fixed plate 2 and connecting bushing 1 is respectively arranged at the both ends of elastic axis 3, shakes at two
Two are connected between arm restraining board 2, and spring(-supported) mount 5 is respectively set in the hinged place of two Rocker arm 4s with the axisymmetric Rocker arm 4 of damping,
6 one end of spring is mounted on spring(-supported) mount 5, and the other end of spring 6 is connected by pressure spring mechanism 7, when elastic axis 3 is pressurized, rocker arm
Direction compressed spring 6 of the hinged place to separate guideway 32.
The present invention allows the power a part of load on connecting bushing on elastic axis, there are also one by the design of rocker arm
Divide component to rocker arm, it can be appreciated that by force resolution, structure of the invention makes damper by same as the prior art
Pressure when, buffering and damping effect is more preferable.In reseting procedure, jolt caused by the reciprocating motion of spring in the prior art, due to
The power of spring elongation of the invention with the stress of damper be it is vertical, therefore, there's almost no in the prior art in the present invention
Spring jolts with the coaxial bring reciprocating motion of elastic axis, during naturally also just reducing spring reset, repeatedly to elastic axis
Pressure stretching and number of contractions, extend the service life of elastic axis.
Embodiment 2
As a kind of optimization design to examples of implementation 1, the Rocker arm 4 is made of two hinged rocking bars in centre, two rocking bars
The other end it is hinged with two rocker arm fixed plates 2 respectively, two Rocker arm 4s constitute plane quadrilaterals.
The material of several springs 6 is identical with size.
Using double rocker designs, the size of rocker arm can be designed bigger, and intensity is higher, and rocker arm and elastic axis are one
In a plane, stability is good.Rocker arm is hingedly constituted using two rocking bars, structure is simple, but stable structure, and spring mounting is fast, side
Just installation maintenance.Spring material and size keep identical, to reduce out-of-balance force.
Embodiment 3
As a kind of optimization design to examples of implementation 2, the elastic axis 3 is hydraulic stem, and guideway 31 is cylinder body, guiding axis
32 be piston rod.
The spring(-supported) mount 5 is bar or plate with several spring fixing grooves, and 6 one end of spring is mounted in spring fixing groove；
Pressure spring mechanism 7 includes the bracing wire an of pressure spring plate and connection pressure spring plate, is drawstring through among spring 6, keeps pressure spring plate another with spring
One end connection.
The bracing wire of pressure spring mechanism 7 on two rocker arms mounts, and spring on spring(-supported) mount 5 and pressure spring mechanism are idol
Number setting, and be located at elastic axis two sides and be symmetrical arranged.
This gives a kind of modes of elastic axis to be arranged between bracing wire using the common hydraulic stem of the prior art
Mounting is quickly connection or dismounting for convenience, installs spring on spring(-supported) mount, is convenient for changing maintenance.And the method can be greatly
The service life of hydraulic stem itself is played, compared with prior art, extend hydraulic stem uses the time.
Through the foregoing embodiment, it can be seen that the present invention, will be along the power of elastic axis by two rocker arms and spring assembly
The power normal thereto on spring is resolved into, the pressure to elastic axis is reduced, extends its service life, and damping is imitated
Fruit is more preferable；In single spring breaking down, replacement only need to be taken down, without dismantling entire damper.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, this not shadow
Ring substantive content of the invention.
