Description

A kind of packing ring

Technical field

This utility model relates to the EMUs technical field of high-speed railway, particularly relates to a kind of packing ring.

Background technology

At present, motor train unit bogie is installed connection various securing member, and in use, securing member is mainly spiral shell Bolt, nut, spring washer, due to the many reasons such as vibration in driving process so that the spring pad used by nut that volume is bigger Enclosing and install tightening, can occur to loosen phenomenon after running a period of time, spring washer anti-loosing effect is poor, needs maintenance dimension Protect personnel's running check nut, packing ring fastening situation, fairly time consuming arduously, as maintainer once slips, be easily caused bolt Nut loosening is lost, the potential safety hazard to railway transportation band.A kind of side preventing bolt or nut loosening is had in machinery industry Using stop washer to replace spring washer in method, the method is to have locking effect to bolt or nut loosening, and bolt or spiral shell Mother still is possible to loosen；If all installing stop washer at screw bolt and nut, then needing four presser feets needs to stick up after tightening Rise, comparatively laborious, affect work efficiency；Live according to screw bolt and nut spot welding or screw bolt and nut spot welding is lived, or spiral shell The modes such as bolt thread damage, the effect of paying brought is to be not easy to maintenance, and screw bolt and nut can not reused.

Accordingly, it would be desirable to invent a kind of nut novel, that to be applicable to volume bigger, packing ring can enter one tightening to install Step ground carry out being locked again can the fixing packing ring of stop, be just particularly important.

Summary of the invention

In view of this, goal of the invention of the present utility model is for the problems referred to above, it is provided that a kind of packing ring, i.e.

May be used for being locked again can the fixing packing ring of stop, and simple in construction, production efficiency are high.

For achieving the above object, this utility model realizes by the following technical solutions:

A kind of packing ring, including flanging, cross break tongue limit, perpendicular folding tongue limit, centre bore in annular bending, the outer flanging of annular, annular, Described annular bending is that linear and 100 ° of angles of cone angle the horizontal direction annular bending of top arc is arranged at vertical direction Form.

The described outer flanging of annular, annular interior flanging are separately positioned on outside and the inside line of annular bending, and ring Shape bending, the outer flanging of annular, annular infolding marginal ray slip are an annular overall structure so that the inside edge structure of flanging in annular Become centre bore.

Described cross break tongue limit flattened rectangular shape in horizontal direction is arranged on the outer side edges on the right side of the outer flanging of annular along upper, institute The perpendicular folding tongue limit flattened rectangular shape in horizontal direction stated is arranged on the outer side edges on front side of the outer flanging of annular along upper, and cross break tongue Limit, perpendicular folding tongue limit 90 ° of right angle angle mutually perpendicular direction in horizontal direction are arranged.

Beneficial effect: a kind of packing ring disclosed in this utility model, annular bending is the linear folding of top arc at vertical direction Curved setting, in the outer flanging of annular, annular, flanging is separately positioned on outside and the inside line of annular bending, and cross break tongue limit is arranged on The outer flanging outer side edges of annular is along upper, and perpendicular folding tongue limit is arranged on the outer flanging outer side edges of annular along upper, and cross break tongue limit, perpendicular rolls over tongue limit Rectangular 90 ° of angle mutually perpendicular directions are arranged so that nut, packing ring install that can to carry out locking further solid tightening Fixed and the packing ring of stop, and simple in construction, production efficiency are high, it is ensured that steady in driving process, is particularly well-suited to respectively Plant the use in motor train unit train driving process.

7-centre bore.

Detailed description of the invention

Below in conjunction with Figure of description, this utility model is described in detail, it should be noted that of the present utility model Implement to be not limited to following embodiment.

As Figure 1-Figure 2, described a kind of packing ring, including flanging 3, horizontal stroke in annular bending 1, the outer flanging 2 of annular, annular Folding tongue limit 4, perpendicular folding tongue limit 5, centre bore 6, described annular bending 1 is that top arc is linear and cone angle 100 ° at vertical direction The horizontal direction annular bending of angle arranges and forms.

The described outer flanging 2 of annular, annular interior flanging 3 are separately positioned on outside and the inside line of annular bending 1, and In annular bending 1, the outer flanging 2 of annular, annular, flanging 3 is smoothly connected is an annular overall structure so that in annular, flanging 3 is interior Edge constitutes centre bore 6.

Described cross break tongue limit 4 flattened rectangular shape in horizontal direction is arranged on the outer side edges on the right side of the outer flanging 2 of annular along upper, Described perpendicular folding tongue limit 5 flattened rectangular shape in horizontal direction is arranged on the outer side edges on front side of the outer flanging 2 of annular along upper, and cross break Tongue limit 4, perpendicular folding tongue limit 5 90 ° of right angle angle mutually perpendicular direction in horizontal direction are arranged.

Embodiment:

After nut is pressed on packing ring of the present utility model so that because being subject between flanging 3 in the outer flanging 2 of annular and annular Power causes elastic deformation, and meanwhile, nut is by from the reverse elastic force between flanging 3 in the outer flanging 2 of annular and annular, making Obtaining the thread pressure increase of nut and bolt junction, frictional force increases simultaneously the most therewith, so that nut is by stronger Vibration time, loosen the most more difficulty,

Serve good anti-loosing effect；After additionally nut is fixing, then cross break tongue limit 4 is rolled in tongue limit 5 with perpendicular Any of which one, be folded to nut side by installation site, the most again by cross break tongue limit 4 with in perpendicular folding tongue limit 5 wherein another Individual that do not roll over, regarding installation site close call, by installation site negative side

To being folded to installation site edge opposite side, packing ring of the present utility model is made to play stopping function, so that nut When by stronger vibration, do not loosen.

Above-mentioned embodiment only for technical characterstic of the present utility model and design are described, its objective is to be

The technical staff being familiar with this area technique is allowed to will appreciate that content of the present utility model and to be carried out, and Protection domain of the present utility model can not be limited with this, all be made according to spirit of the present utility model and embodiment Equivalence change or modification, all should contain in protection domain of the present utility model.
