Description
Technical field
The present invention relates to a kind of screw type frcition dampers, and in particular to a kind of building engineering structure is in earthquake, wind shake
Or vibration damping, antishock device under other percussions.
Background technique
In the prior art, traditional frcition damper is mainly made of sliding panel and clamping plate, then is compressed by pretension bolt.
Due to increasing with Rubbing number, friction surface wear causes coefficient of friction that can change correspondingly, while gap can also become larger,
Therefore it cannot keep damping force long-time using pretension bolt, many cycles are stablized.
It how to be directed to the defect of conventional friction damper, keeps properties of product more stable, longer life expectancy is such current product
The urgent problem in marketing.
Summary of the invention
The purpose of the invention is to overcome the defect of conventional friction damper, provide that a kind of stability is good, the service life is long
Friction screw damper.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
A kind of screw type frcition damper, the master cylinder cylinder including both ends open, the master cylinder cylinder are arranged on intermediate inner wall
There is trapezoid spiral slot, the both ends open of master cylinder cylinder is respectively arranged with guide sleeve, master cylinder cylinder is provided with piston rod, piston rod
Length is greater than the length of master cylinder cylinder, and piston rod runs through two guide sleeves, and there are two pressing plate, two pressing plates for installation on the piston rod
Between be fixedly installed piston, the outer surface of piston is the trapezoidal thread cooperated with trapezoid spiral slot, one end of the piston rod
Equipped with earrings, the other end is equipped with secondary cylinder barrel, and the pair cylinder barrel is installed on guide sleeve, is also equipped with ear outside the guide sleeve
Ring.
Scheme as a further preference is provided with bearing between the piston and piston rod.
Scheme as a further preference is provided with the bolt for fixed piston through pressing plate.
Scheme as a further preference is provided with sliding bearing on the part that the piston rod is contacted with guide sleeve.
Scheme as a further preference, internal diameter one week of the guide sleeve offer slot, one Zhou Shangshe of piston rod outer diameter
It is equipped with dustband, dustband is placed in slot.
Compared with prior art, a kind of screw type frcition damper of the invention, when master cylinder cylinder and piston rod generate phase
When to displacement trend, the frictional force of master cylinder cylinder spiral inner wall slot Yu piston face trapezoidal thread contact site need to be overcome, work as earthquake
When the axle power of generation is greater than the frictional force between piston and master cylinder cylinder, relative displacement is generated.Frictional force makes in reciprocating motion
Extraneous seismic force is converted into interior energy, is spread in a manner of heat, so that earthquake energy, reaches the mesh of protection structure safety
, specifically have the advantage that
1, the frictional force between master cylinder cylinder spiral inner wall slot and piston face trapezoidal thread, the i.e. surrender of friction screw damper
Power can change equivalent friction angle by changing the lead of spiral, or by selecting the master cylinder cylinder of different materials to change with piston
The coefficient of friction become between them obtains, therefore is readily available the damper product of different parameters.
2, friction screw dampers contact mode is two spiral face contacts, when contact surface has certain abrasion, in axis
Under the influence of power, can automatic compensation gap, can still obtain good contact, damper performance is more stable.
3, the friction screw damper is mechanical type friction, without excessively considering inner sealing, it is only necessary to carry out dust-proof place
Reason, enhances the reliability and service life of product.
Detailed description of the invention

Specific embodiment
The optimal technical scheme that the invention will now be described in detail with reference to the accompanying drawings.
As shown in Figure 1, a kind of screw type frcition damper of the invention, the master cylinder cylinder 1 including both ends open, master cylinder cylinder
1 is provided with trapezoid spiral slot on intermediate inner wall, and the both ends open of master cylinder cylinder 1 is respectively arranged with guide sleeve 5, guide sleeve and master
Cylinder barrel is connected through a screw thread, and guide sleeve is connected through a screw thread with master cylinder cylinder, and master cylinder cylinder 1 is provided with piston rod 4, piston rod 4
Length be greater than the length of master cylinder cylinder 1, piston rod 4 runs through two guide sleeves 5, on the piston rod 4 installation there are two pressing plate 10,
Piston 2 is fixedly installed between two pressing plates 10, the outer surface of piston is the trapezoidal thread cooperated with trapezoid spiral slot, the work
One end of stopper rod 4 is equipped with earrings 9, and the other end is equipped with secondary cylinder barrel 8, and secondary cylinder barrel 8 is installed on guide sleeve 5, outside the guide sleeve 5
It is also equipped with earrings 9.
Further, bearing 3 is provided between the piston 2 and piston rod 4；It is provided with through pressing plate 10 and lives for fixed
The bolt 11 of plug 2；Internal diameter one week of the guide sleeve 5 offers slot, and 4 outer diameter of piston rod was provided with dustband 7 on one week, dust-proof
Circle 7 is placed in slot.
1 inner wall trapezoidal thread slot of master cylinder cylinder and 2 outer wall trapezoidal thread of piston helix angle having the same and identical cross
Section, therefore can be with close contacting fit.
Master cylinder cylinder both ends are equipped with guide sleeve, and guide sleeve centre is equipped with sliding bearing, can make piston rod axially position, from
And realize that its is axially displaced.
Internal piston is equipped with bearing, matches with piston rod, when piston rod axial movement, can make piston opposing pistons bar
Radial rotating.
When piston rod tension, pressure, with piston generate along damper axial direction movement tendency, due to piston with
It is trapezoidal thread cooperation between cylinder barrel, and lead angle is greater than 5 °, is not in the situation that piston and cylinder body lock, piston can be
It makes rotating motion during along damper axis direction linear motion along cylinder body trapezoidal thread, piston and cylinder body cooperation
Trapezoidal thread parameter sliding friction, the meeting of frictional force generate one with piston along the opposite resistance of the damper axis direction of motion
Power, here it is the power output principles of damper.
When building engineering structure because of the extraneous load such as earthquake by impacting, the both ends earrings 9 connecting with structure will impact
Power passes to the piston rod 4 and master cylinder cylinder 1 at damper both ends respectively, when master cylinder cylinder 1 and the generation relative displacement trend of piston rod 4,
The frictional force that 1 spiral inner wall slot of master cylinder cylinder Yu 2 surface trapezoidal thread contact site of piston need to be overcome, when the axle power that earthquake generates is big
When the frictional force of piston 2 and 1 helical interfaces of master cylinder cylinder, relative displacement is generated.Frictional force makes the external world in reciprocating motion
Seismic force is converted into interior energy, is spread in a manner of heat, so that earthquake energy, achievees the purpose that protect structure safety.
