Description
[technical field]
The present invention relates to the technical field of fastener, especially a kind of technical field of anti-loosening fastening type flange nut.
[background technique]
Nut is that have internal screw thread and with screw rod with the use of the machine components to passing movement or power.Currently,
It is usually to be cooperated using bolts and nuts, together by two components fixing assemblings in the components assembly of automobile.Zero
In the long-term use process of component, locking is always an important subject being threadedly coupled.Usually in following two situation
Under, can make to be threadedly coupled and relax: first is that under shock and vibration or varying load effect, the frictional force between screw thread pair may reduce or
After being repeated several times connection will loosen for pop-off, this phenomenon；Second is that under high temperature or the biggish situation of temperature change, by
In being threadedly coupled and creep and stress relaxation occur for the material of connected piece, pretightning force in connection and frictional force can also be made gradually
Reduction leads to connection failure.And screw thread once loosens, and will affect the normal operation of machine or even causes major accident, therefore having must
Locking processing is carried out to thread connection.
It there are many equipment is carried out using the flange nut of gasket and nut integral type in existing industrial circle
It fastens locking.For existing flange nut when connecting loaded, screw thread has the trend being stretched on bolt, and the screw thread on nut
With compressed trend, the two deformation tendency is on the contrary, so that load suffered by screw thread is concentrated mainly on and spiral shell on nut
At the first lap screw thread that bolt is connected, each circle successively successively decreases later, and the load on each section screw thread is unevenly distributed, threaded connection
Fatigue strength is poor, be easy to cause the deformation failure of screw thread, and service life is shorter, while also resulting in nut and bolt appearance pine
It relaxes or falls off, the normal operation for influencing to influence machine even causes major accident, and anti-loosing effect is poor.
[summary of the invention]
The object of the invention is to solve the problems of the prior art, a kind of anti-loosening fastening type flange nut is proposed, tie
Structure is simple, locking reliable, being dismounted for multiple times without reducing anti-loosening property, improve the fatigue strength of threaded connection, be unlikely to deform,
It can effectively prevent flange nut from loosening sliding against tightening direction, the reliability for improving threaded connection is not easy to loosen, system
Facilitate, long service life.
To achieve the above object, described the invention proposes a kind of anti-loosening fastening type flange nut, including nut main body
Nut main body be hex nut, the top of the nut main body is equipped with flange circle, the nut main body and flange circle
Inside is equipped with screw thread through the bolt hole cooperated with bolt is equipped in the bolt hole of the inside of the nut main body, described
The end face of flange circle is equipped with annular groove, and the excircle of the annular groove is uniformly provided with several anti-slop serrations outward.
Preferably, the bottom of the bolt hole is equipped with spring washer.
Preferably, the depth of the annular groove is identical as the height of the anti-slop serrations.
Preferably, the anti-slop serrations be unidirectional helical teeth, the teeth directional of the anti-slop serrations with turn it is contrary.
Preferably, the tooth side of the anti-slop serrations is arc-shaped.
Preferably, the number of teeth of the anti-slop serrations is 24 teeth.
Preferably, the nut body and flange circle is all made of high strength steel and is made.
Beneficial effects of the present invention: for the present invention by elastic washer, structure is simple, locking reliable, being dismounted for multiple times without
It reduces anti-loosening property to improve the fatigue strength of threaded connection by annular groove, be unlikely to deform, increases the service life of screw thread,
The distribution of load suffered by each section screw thread tends to uniformly, by anti-slop serrations, increase the frictional force of contact surface, Neng Gouyou on nut
Effect prevents flange nut from loosening sliding against tightening direction, is made by using high strength steel, and improve threaded connection can
It is not easy to loosen by property, structure is simple, easy to make, long service life.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.
