Description
Technical field
The utility model belongs to technical field of fastening, is related to a kind of reaction force washer.
Background technique
In the fastening system of common " bolt+nut (+gasket)+spanner ", bolt, can not as most important part
What is avoided will receive stretching (tensile stress), torsion (torque+shear stress) and bending (moment of flexure+shearing) effect.As it can be seen that bolt by
Power situation is more complicated, increases the probability of fastener failure.
In above-mentioned fastening system, stretching action is the key that play the role of fastening, and should ensure that the effective pull of fastening system；It turns round
Turning to be caused by tightening nut, nut and bolt are connected with screw thread pair, due to the presence of frictional force, while rotating nut, spiral shell
Bolt can also bear twisting action, if to eliminate the twisting action of bolt, need to change the structure of nut；Buckling phenomenon be by
In rundown process, caused by bolt bears spanner bias force, bias force is eliminated, needs to be arranged corresponding counter-force structures, phase
It is simple for eliminating the twisting action of bolt.
Summary of the invention
The utility model provides a kind of reaction force washer, cooperates corresponding fastening tool, provides inside fastening system anti-
Active force overcomes the biasing force phenomenon occurred in above-mentioned fastening system, make it is bolt strained simple, improve fastener safety,
Reliability and the convenience of operation.
The technical solution of the utility model is as follows:
A kind of reaction force washer, including washer body, washer body are integrally formed, and the front of washer body is set as
The reverse side of smooth flat, washer body is toothed surface, and the outer ring of washer body is set as spline structure, and the inner ring of washer body is set
It is set to hollow out circle.
Further, the toothed surface uses tooth form or annular knurl plane, and the shape of toothed surface is wave-shaped.
Further, the surface of the smooth flat is provided with cure process layer.
Further, the spline structure uses involute spline.
Further, the circular diameter of the internal diameter of the toothed surface and hollow out is identical, and the outer diameter of toothed surface is less than spline structure
Internal diameter.
Under the premise of not changing common " bolt+nut " structure, increase reaction force washer.
Reaction force washer front is that the resistance to flat surface grinding of hardening is contacted with nut, reduces the frictional force of contact surface, prevents
Only or contact surface is reduced when tightening because damage caused by friction is convenient for so that every group of final pretightning force of bolt be made to reach unanimity
Realize that pretightning force accurately controls；Reaction force washer outer ring is equipped with spline or class spline structure, for by fastening tool
Reaction force is transmitted to reaction force washer；Reaction force is then transmitted to by fastener by the reaction force washer reverse side,
It is equipped with tooth form or annular knurl, increases mechanical resistance, or even forms residual indentation on by fastener, plus reaction force washer and
By the frictional force between fastener, so that reaction force washer can transmit sufficiently large reaction force.
Detailed description of the invention
Fig. 1 is the schematic three dimensional views of reaction force washer.
Fig. 2 is reaction force gasket applications example.
Serial number is successively in Fig. 2 are as follows: washer body 100；Connected piece 2；Bolt 3；Nut 4；Spline structure 110；Toothed surface
120；Hollow out circle 130.
Specific embodiment
To keep the technical characteristics of the utility model, implementation and purpose and effect apparent clear, in conjunction with attached drawing to this
The technical solution of utility model is specifically addressed.
Referring to attached drawing 1, a kind of reaction force washer, including washer body 100, washer body 100 are integrally formed, washer
The front of ontology 100 is set as smooth flat, and the reverse side of washer body 100 is toothed surface 120, and the outer ring of washer body 100 is set
It is set to spline structure 110, the inner ring of washer body 100 is set as hollow out circle 130.
Toothed surface 120 uses tooth form or annular knurl plane, and the shape of toothed surface 120 is wave-shaped.The surface of smooth flat is set
It is equipped with cure process layer, the plane that smooth flat uses nitriding and polishes.Spline structure 110 uses involute spline.Toothed surface
120 internal diameter is identical with the diameter of hollow out circle 130, and the outer diameter of toothed surface 120 is less than the internal diameter of spline structure 110.
In one embodiment of the utility model, as shown in Fig. 2, face-up covering washer body 100 in bolt 3
On, hex nut 4 is then screwed on again.Then the outer-hexagonal of nut 4 is connect with the interior hexagonal of fastening tool inner sleeve, by washer
The external splines of ontology 100 is connect with the internal spline of fastening tool outer sleeve.At this point, Qidong fastening tool, inner sleeve drives spiral shell
Mother 4 rotates clockwise, and generates pretightning force；Under the action of pretightning force, the waveform toothed surface and quilt of the reverse side of washer body 100
Connector 2 fits closely, and generates huge mechanical resistance and frictional force, or even forms residual indentation, prevent reaction force washer 1 with
Turn；The external splines of reaction force washer 1 prevents the rotation of fastening tool outer sleeve again.As it can be seen that reaction force washer 1 is deposited
The purpose for transmitting reaction force inside fastening system is being realized, to eliminate bias force, is making bolt strained to tend to be simple.
The above is only an embodiment of the present invention, are not intended to limit the embodiments of the present invention and protection
Range, for a person skilled in the art, it should be understood that all to be made using the utility model specification and diagramatic content
Same replacement and obvious variation gained scheme, should all include within the protection scope of the present utility model.
