Description
Technical field
The present invention relates to a kind of nut anti-looseness technologies, more particularly, to the braking and locking nut of thread connection.
Background technique
It in common thread connection, will be pre-tightened when the overwhelming majority is threadably coupled within assembly, it is therefore intended that enhancing connection
The rigidity that connects, compactness, anti-loose ability and prevent sliding by transverse load, the bolt-connection of oscillating load.
Currently, there are many stop nuts, principle is: increasing the contact area of nut and connected compcnent, increases loosening
The moment of resistance；It is embedded in non-metallic insert in nut, brakes screw thread with non-metallic insert, is locked and increased the resistance of loosening
Square；Double nut locking；Change threaded engagement state and increases the moment of resistance of loosening；Etc..But above-mentioned overwhelming majority stop nut
The sliding by transverse load, alternating load, the bolt-connection of oscillating load is not prevented.Its basic reason is: thread connection
Under the action of by transverse load, alternating load, oscillating load, couple the moment of friction of screw thread by transverse load, alternating load,
The external force of oscillating load overcomes, and sliding, sliding occur for internal and external threads；Change threaded engagement state and increase the moment of resistance of loosening,
This structure can effectively anti-thread connection loosen, but change threaded engagement state, make the internal screw thread strength reduction of nut, screw thread connection
Connect decrease.So mechanic author to design the screw bolt and nut in thread connection screw lemon it is next not by transverse load,
Under the action of alternating load, oscillating load, the nut apparatus that is subjected to displacement.
Summary of the invention
A kind of nut is provided the technical problem to be solved by the present invention is to the status for the prior art, bolt-connection exists
The locking nut of sliding, sliding does not occur for internal and external threads under the action of by transverse load, alternating load, oscillating load, it can have
Effect ground carries out bolt and nut connection, and screw bolt and nut will not occur under transverse load, alternating load, oscillating load effect
The nut apparatus of relative displacement, the locking nut is sturdy and durable, does not weaken screw strength, is hardly damaged the spiral shell of bolt and nut connection
Line is easy installation, is easy maintenance.
The technical scheme of the invention to solve the technical problem is: in thread connection, it is a kind of to use braking member
Brake the locking nut of screw thread, it is characterised in that: including the braking member that head is inclined-plane or the conical surface is arranged in nut,
Under the action of thrust device, the inclined-plane or the conical surface on braking member head be engaged with the boundary line of externally threaded crest tooth side, brake,
Locking, wherein braking member is radially arranged in the tooth side of the internal screw thread of nut, makes the inclined-plane or the conical surface on braking member head
It is engaged with the boundary line of externally threaded crest tooth side.
The tooth side that above-mentioned braking member is radially arranged in the internal screw thread of nut refers to that the center line of braking member is fallen in

It is inside from nut gabarit, be radially arranged in the tooth side of the internal screw thread of nut, and with the same hole of braking member, coaxial line, screw
Screw or swivel nut, screw or swivel nut press spring, and spring presses braking member again, the inclined-plane or the conical surface on braking member head and outer
Boundary line contact, occlusion, the braking, locking external thread of the crest tooth side of screw thread, thus braking and locking thread connection, adjusting screw
Or swivel nut spinning spring dynamics, that is, adjust braking member braking and locking screw thread degree.
The thrust device of above-mentioned braking and locking nut, the nut of big specification or the nut lifting force device of thickening can be with axis
To setting, the thrust of thrust device acts on the braking for being radially arranged in the tooth side of the internal screw thread of nut by transfer medium
Element is contacted with the boundary line of externally threaded crest tooth side by the inclined-plane or the conical surface on braking member head, be engaged, braked, locked
External screw thread, thus braking and locking thread connection.
The braking member of above-mentioned braking and locking nut is distributed in the radial orientation of nut, and rides respectively, and externally threaded
Crest contacts, under the action of thrust device with the boundary line of carrying tooth side and non-bearing tooth side, the inclined-plane on braking member head
Or the conical surface is close to the boundary line of externally threaded crest tooth side, is engaged, is braked, locking external thread.
External screw thread has carrying tooth side and non-bearing tooth side, and external screw thread has crest and carries the boundary line of tooth side, have crest with
The boundary line of non-bearing tooth side, when the friendship of the inclined-plane or the conical surface on main braking member head and externally threaded crest and carrying tooth side
Boundary line contact, occlusion, braking, locking external thread are effectual, if being radially arranged in the tooth side of the internal screw thread of nut
Braking member, separate the tooth side that the internal screw thread of nut is arranged in auxiliary braking element, and externally threaded crest and non-hold
Boundary line contact, occlusion, the braking, locking external thread of tooth side are carried, in this way, main braking member is braked externally threaded crest and held
The boundary line of tooth side is carried, auxiliary braking element brakes externally threaded crest and the boundary line contact of non-bearing tooth side, occlusion, system
Dynamic, locking external thread, seems, the boundary of the boundary line and crest and non-bearing tooth side of an externally threaded crest and carrying tooth side
It rides respectively on line main braking member and auxiliary braking element.
Compared with the prior art, the advantages of the present invention are as follows: the braking that head is inclined-plane or the conical surface is provided in nut
Element, under the action of thrust device, the inclined-plane or the conical surface on the head of braking member and the boundary line of externally threaded crest tooth side
