Description
Technical field
The invention belongs to technical field of fastening more particularly to a kind of general self-locking fastening nuts and fastening assembly.
Background technique
Nut, that is, nut is the part being threaded together with bolt or screw rod for playing the role of fastening.The working principle of nut
It is to be carried out using the frictional force between nuts and bolt self-locking, this self-locking reliability will reduce in dynamic loading, and one
As nut in use due to vibration etc. other reasons can voluntarily loosen.Locking nut, which is that common one kind is locking, arranges
It applies, function is mainly locking, antivibration.There are three types of existing locking nut is usual, the first be using double nut be screwed in it is same
On support bolt, a screw-down torque is added between two nuts, so that being bolted reliable；Second is dedicated locking spiral shell
Mother needs to be used together with check washer；The third is to be drilled with perforative screw thread in outer round surface to the inner circle flank of nut
Hole, to apply the power of a centripetal direction to screw thread, prevents locking nut from unclamping for being screwed into the sunk screw of minor diameter.
Above-mentioned three kinds of modes are required to other assemblies and are used cooperatively, and structure is complicated, is not easy to install, and the practicability is poor, and it processes work
Skill is complicated, at high cost, poor reliability.
Summary of the invention
The present invention provides a kind of simple structure, the operation is stable, in order to solve shortcoming in the prior art convenient for peace
Dress, the general self-locking fastening nut and fastening assembly that applied widely, anti-loosing effect is good.
In order to solve the above technical problems, the present invention adopts the following technical scheme: a kind of general self-locking fastening nut, including spiral shell
The contact surface of maternal body, nut body and workpiece is fastening face, and the fastening face of nut body is set as inclined-plane, inclined-plane and nut sheet
The vertical plane of the screw thread axially bored line of body forms inclination angle A.
The range of inclination angle A is 0.1 ° -45 °.
The threaded hole lower end of nut body is provided with compensation hole, and the threaded hole that the diameter of compensation hole is greater than nut body is straight
Diameter.
A kind of general self-locking fastening assembly, including screw bolt and nut ontology, nut body are threaded in bolt end.
Bolt end is threaded with the stiffnut between nut body and workpiece.
By adopting the above technical scheme, the present invention has the advantage that
1, the present invention is pre- next by nut body, on the one hand, the fastening face of nut body is set as inclined-plane, compared with conventional nut
The rubbing surface of its fastening face is increased, to increase frictional force, fastening effect is improved and on the other hand acts in fastening face
Active force generate the component along bevel direction, and act on bolt and make its axis run-off the straight, thus in whole circumference direction
Upper formation is self-locking, prevents nut body from loosening, while workpiece reacts on the fastening face of nut body, so that workpiece pre-tightening
Fastening face；The fastening face of nut body is set as inclined-plane, pre- next, the axis of nut body with the bolt axis that is acted on not
Again on same straight line, formed on 360 ° of circumferencial directions self-locking, anti-loosing effect is good.
2, the threaded hole lower end of nut body is provided with compensation hole, and nut body acts on bolt and makes pre- next
Slight bending deformation occurs for bolt, and the setting of compensation hole can carry out dimension compensation to the bending of bolt, reduce bolts bend with
The stress that nut body generates, improves its use intensity, on the one hand the setting of compensation hole adapts to nut body during installation
The deformed cooperation of bolts bend, on the other hand provides elastic space appropriate, increases its scope of application.
3, the present invention can be realized self-locking by the bevel structure of nut body fastening face, reach anti-loosening effect, be tied
Structure is simple, is easily installed, and processing cost is low, easy to spread, practical.
4, under the high particular condition of use intensity, the setting of stiffnut plays reinforcement work to the self-locking of nut body
With keeping its structure more stable, anti-loosing effect is more preferable.
