The invention discloses a kind of auxiliary connection of the locking nut with memorial alloy ring, for locking connected piece, it includes screwed locking member and is arranged on locking member the memorial alloy pad contacted with connected piece surface.The present invention is not only simple in structure, and it is firm to lock, and also with good decay resistance, can be used on the harsh fastening position of the environment such as ship, chemical industry.
Description
Technical field
The present invention relates to fastener areas, and in particular to a kind of auxiliary connection of the locking nut with memorial alloy ring.
Background technology
Fastener, be fastenedly connected with and apply an extremely wide class machine components, its energy, electronics, electrical equipment,
It is used widely in the industries such as machinery, chemical industry, metallurgy, mould, hydraulic pressure.Various machineries, equipment, vehicle, ship, railway,
Above bridge, building, structure, instrument, instrument, chemical industry, instrument and articles for use etc., it can be seen that fastener miscellaneous, is
Most widely used mechanical basic part.Fastener, can be because the vibration or the corrosion of environment of equipment during long-time use
Loosened etc. reason, cause connected piece to disintegrate and come off, caused security incident or produce economic loss.
Existing auxiliary connection is locking generally to place pad between plain nut and bolt, and spiral shell is withstood using the elastic force of pad
It is female.But pad shock resistance under vibration environment high is poor, it is more difficult to meet locking requirement, and screw-down torque is larger, is set to various
Standby maintenance brings inconvenience.
For above-mentioned deficiency, existing frequently-used anti-loose method has：1st, machinery is locking, and the method is to use locking nut retainer
The relative rotation of locking nut is directly limited, it has the shortcomings that dismounting is inconvenient, such as using pin of opening one's mouth, series winding steel wire and stop
Packing ring etc., because locking nut retainer does not have a pretightning force, locking nut pine when falling back on stop position locking retainer just act as
With, thus, it is actually not locking using this method of locking nut but avoid withered and fallen；2nd, riveting rushes locking, is used after tightening
The methods such as point, welding, bonding are rushed, locking nut pair is lost motion sub-attribute and is connected as non-disconnectable linking, this method
Defect be that tightening latch is used only once, and dismantle it is very difficult, it is necessary to damaging bolt pair could dismantle；3rd, rub locking, this
It is a kind of most widely used anti-loose method, this method produces a kind of malleation not changed with external force between locking nut pair
Power, to produce a kind of frictional force that locking nut pair can be prevented to relatively rotate, this normal pressure to pass through axial direction or simultaneously two
Completed to locking nut pair is compressed, such as using elastic washer, double nut, self-locking nut and inserts locking nut；4th, construct
It is locking, it is to be constructed in itself using locking pair of nut, using right-and-left threaded locking mode.
In above-mentioned technical proposal, generally existing complex structure, auxiliary connection dismounting is inconvenient, corrosion-resistant, to using ring
The shortcomings of border requires high.
Therefore, a kind of auxiliary connection of the locking nut with memorial alloy ring is designed, is not only simple in structure, it is firm to lock,
Also there is good decay resistance, the harsh fastening position of the environment such as ship, chemical industry is can be used on, it is clear that with positive reality
Meaning.
The content of the invention
Goal of the invention of the invention is to provide a kind of auxiliary connection of the locking nut with memorial alloy ring.
To achieve the above object of the invention, the technical solution adopted by the present invention is：A kind of locking screw with memorial alloy ring
Female auxiliary connection, for locking connected piece, it includes screwed locking member and is arranged on locking member and connected piece
The memorial alloy pad of surface contact.
Further, the locking member includes bolt and the memorial alloy locking nut coordinated with bolt.
Further, the bolt is hexagon-headed bolt, foundation bolt, snap bolt, square head bolt or dormant bolt.
Further, the locking member includes stud and the memorial alloy locking nut coordinated with stud.
Further, the memorial alloy locking nut is provided with memorial alloy ring.
Further, the memorial alloy locking nut is turret head or square.
Further, it is additionally provided with buffering spacer between the memorial alloy pad and connected piece.The buffering spacer is
Common spring washer, flat shim, SW with outside ring, embossing pad or band tooth pad.
The performance rate of the bolt of the invention or stud be 3.6,4.6,4.8,5.6,6.8,8.8,9.8,10.9,
12.9 grades；The performance rate of the memorial alloy locking nut is 4,5,6,8,9,10,12 grades.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
1. auxiliary connection of the invention memorial alloy pad with bolt or stud is constituted, and according to specific use demand, then is matched somebody with somebody
Conjunction has the memorial alloy locking nut of corresponding bolt or stud, is made because pad and locking nut are memory alloy material,
With good decay resistance, it is adaptable to the harsh fastening position of the environment such as ship, chemical industry；
2. memorial alloy pad of the invention has shape memory function, super-elasticity, excellent damping and amortization and corrosion resistance, can
Prevent connected piece in use, because the reason such as the vibration of equipment or the corrosion of environment loosens, prevent from being connected
Part disintegrates and comes off, it is to avoid security incident or economic loss；
3. the memorial alloy ring on memorial alloy locking nut of the invention can produce restoring force, increase bolt or stud and spiral shell
The radial friction of female thread portion, fastens connection firm；
4. auxiliary connection simple structure of the invention, easy to process, is suitable to popularization and application.
