Description
Technical field
The utility model relates to a kind of damper, especially a kind of pin rod stick slip bearing-type damper.
Background technique
Damper is also known as damping unit, is the increase resistance that the vibration generated to be impacted decays made quickly
The device of Buddhist nun.Damper mainly divides liquid condenser, gas damper and electromagnetic damper three classes.Ideal liquid condenser has
Oil damper, common oils have silicone oil, castor oil, machinery oil, diesel oil, machine oil, transformer oil etc..According to the practical of Vibration Absorbing System Design
It needs, is best in the range of damping ratio D=0.05~0.2.
Damper is many kinds of, should be very extensive.It is general already in space flight, aviation, military project, firearms, automobile and other industries
All over use.After nineteen seventies, people start that these technologies are converted to the knot such as building, bridge, railway step by step
In structure engineering, develop very rapid.
With the high speed development of the new energy technologies such as solar energy, wind energy, the demand to damper is also increasing, while
Damper is constantly put forward new requirements, especially needs the damper of the big moment of resistance, conventional damper peak torque is only
It can accomplish 20N.m or so, often be unable to satisfy requirement, be badly in need of a kind of damper that the new moment of resistance is big.
Utility model content
The utility model is intended to provide a kind of damper that can generate the big moment of resistance.
To realize the purpose of this utility model, the utility model provides a kind of pin rod stick slip bearing-type damper.
Pin rod stick slip bearing-type damper described in the utility model, including pedestal, flange shaft, cover board, the base
Seat is whole in disk form, and central axial direction is equipped with round hole, and outer rim packs up to form cylindrical seat ring, the cover board to side
Centered on be equipped with round hole annular slab, the cover board is mounted on the seat ring of pedestal, and one is formed between pedestal and cover board
A cavity fills silicone oil in cavity, and the flange shaft is mounted between pedestal and cover board, and the both ends of flange shaft pass through bearing and distinguish
It is connect with the round hole of pedestal and cover board, branch is additionally provided in the flange shaft, branch is located at the sky that pedestal and cover board are formed
It is intracavitary, several pin rods are provided in the branch of flange shaft, the one or both ends end face of the flange shaft is additionally arranged at several installations
Hole, the pedestal, flange shaft are additionally provided with several oil sealings between cover board.
More optimally, the inner surface of pedestal is provided with several pin rods, and with the pin rod mutual dislocation that is arranged in branch.
More optimally, the bearing is sliding bearing, and the outer circle and pedestal and cover board of the sliding bearing carry out interference
Cooperation, the inner circle and flange shaft of sliding bearing carry out clearance fit.
In the utility model, the mounting hole at flange shaft both ends is used to need the device for carrying out damping vibration attenuation to connect with the external world,
It such as connect with the device for revolving and driving of control solar panels rotation, when solar panels are vibrated because of reasons such as wind-force, drives
Flange shaft irregular rotation together therewith, flange shaft drive pin rod and silicone oil to carry out fricting movement, generation rubs in rotary course
It wipes power and resistance and generates the moment of resistance.Also a certain number of pin rods are arranged in the inner surface of pedestal in the utility model together, can
Effectively increase the frictional force of pin rod and silicone oil.
In the utility model, preferred sliding bearing is installed between flange shaft and pedestal and cover board, so that this damping
Device has higher anti-impact force, significantly reduces the maintenance needs of damper, realizes the non-maintaining of damper.
Technical solution described in the utility model can be realized easily greatly using the frictional resistance of pin rod and silicone oil
The moment of resistance meets and requires the moment of resistance very big occasion.Meanwhile also it can reach adjustment resistance by increasing or decreasing the quantity of pin rod
The purpose of torque size.
Detailed description of the invention
Fig. 1 is pin rod stick slip bearing-type damper schematic diagram.
Fig. 2 is pin rod schematic view of the mounting position in flange shaft.
Wherein: 1 is pedestal, and 2 be flange shaft, and 3 be cover board, and 11 be seat ring, and 4 be bearing, and 21 be branch, and 6 be pin rod, and 7 are
Mounting hole, 51 be oil sealing one, and 52 be oil sealing two, and 53 be oil sealing three.
Specific embodiment
It illustrates with reference to the accompanying drawing and how to implement the utility model.
As shown in Figure 1, 2, pin rod stick slip bearing-type damper described in the present embodiment, including pedestal 1, flange shaft 2,
Cover board 3, the pedestal 1 is whole in disk form, and central axial direction is equipped with round hole, and outer rim packs up to form cylinder to side
Seat ring 11 is equipped with the annular slab of round hole centered on the cover board 3, and the cover board 3 is mounted on the seat ring 11 of pedestal 1, and
Form a cavity between pedestal 1 and cover board 3, fill silicone oil in cavity, the flange shaft 2 be mounted on pedestal 1 and cover board 3 it
Between, the both ends of flange shaft 2 are connect with the round hole of pedestal 1 and cover board 3 respectively by bearing 4, and the bearing 4 is sliding bearing,
The outer circle of the sliding bearing is interference fitted with pedestal 1 and cover board 3, and the inner circle and flange shaft 2 of sliding bearing carry out gap
Cooperation is additionally provided with branch 21 in the flange shaft 2, and branch 21 is located in pedestal 1 and the cavity of the formation of cover board 3, pedestal 1 it is interior
