Description
Technical field
The utility model machinery be fastenedly connected technical field, relate in particular to a kind of lock washer and use link and the connected piece of this lock washer.
Background technique
It is the main Connecting format of various mechanical facilities, equipment that bolt connects, the bolted loosening proper functioning that directly has influence on machinery and Safety performance even cause serious accident.
The surface friction drag that bolted locking many employings increase the screw pair relative movement in the prior art is realized.In the real work, the vibration of external load, the wearing and tearing of link and external force can cause the screw pair center pressure at a certain pop-off to the stretching of bolt etc., and frictional force is zero, thereby it is loosening that bolt is connected, and as through effect repeatedly, will cause bolt to connect and lose efficacy.
Bolt connects and is divided into the plain bolt connection, and screw connects and forms such as stud is connected.The object that its fastening with loosening principle is rotation rotates along another object, and the two rotation direction through screw pair is moved up and down, and the distance in the middle of contraction and the amplification reaches fastening and loosening purpose.Want bolt and be connected and do not produce after fastening looseningly, have only the object that will rotate to control in relative static conditions with the interactional object of its generation, just can reach locking purpose.Utilize surface friction drag locking in the prior art, can not be lasting under various external force effects.Mechanical structures more of the prior art are arranged on anti-loose structure between the screw pair or the rotor end.Bolt connect fastening after, reached effective anti-loosing effect, the difficulty but dismounting becomes again, some anti-loose structure even bolt or nut thoroughly destroyed and could dismantle has caused waste of material.Increased the labor intensity of maintenance, thereby use is restricted.
In " the fastening piece NBS compilations " by China Machine Press's publication in 1988, the lock washer of record, as shown in Figure 1 and Figure 2, from its structural analysis, lock washer is provided with in the outside can be to the blocked ear of the object outside plane bending of rotating, and is provided with another blocked ear of another and link generation effect simultaneously.Though chocking construction is arranged on bolted outside, bolted assembling and dismounting have been made things convenient for, but this lock washer can not make nut and bolt keep state of rest, its effect can only make nut and be connected object and keep relative static, even in use, nut does not relatively rotate with being connected object, and bolt still can relatively rotate with nut, so this lock washer does not fundamentally solve locking problem.
Application number provides a kind of lock washer and locking reinforcement assembly for 200710146730.2 Chinese invention patent, this lock washer comprises washer body and is arranged on through hole in the middle of the washer body, also comprise on the described washer body be disposed radially, a plurality of breach that the center is symmetrically distributed and is communicated with through hole; Each breach turns down the anti-release member that forms a projection with the washer body edge of a side that is communicated with the place of through hole towards the table end.This locking fastener assembly comprises threaded fastener and the above-mentioned lock washer that matches with described threaded fastener.The shortcoming of this invention be when described washer body clamped fixing after, described threaded fastener will and washer body between forever locked, want to make both to separate, certainly will cause damage to packing ring, make that packing ring can't continue to use.In addition, the complex structure of this kind lock washer, cost of production height.
The lock washer of prior art or packing ring or dismounting difficulty, otherwise anti-loosing effect is undesirable, so from also thoroughly not solving bolted locking problem in essence.
At above-mentioned deficiency, need to improve existing lock washer or packing ring, make its not only anti-loosing effect ideal, and can from fastener assembly, disassemble more conveniently and can reach reusable purpose.
The model utility content
In view of this, the utility model provides a kind of lock washer, this lock washer simple in structure, cost of production is low, solved lock washer anti-loosing effect of the prior art undesirable, can not reuse and problem such as manufacture cost height.In addition, the utility model also provides a kind of link and connected piece that uses the utility model lock washer.
One of the purpose of this utility model provides a kind of lock washer, and the middle part of described packing ring is provided with endoporus, and the outer rim of packing ring is provided with the blocked ear of outside protrusion, is provided with projection in the end face of described packing ring and/or the endoporus.
Two of the purpose of this utility model provides a kind of link that uses above-mentioned lock washer, described link is threaded connector, described threaded connector comprises threaded threaded stem is set, described threaded stem upper edge self is axially arranged with groove A, and the projection in the described packing ring endoporus can extend among this groove A.
Further, described threaded connector is bolt or double-screw bolt.
Three of the purpose of this utility model provides a kind of connected piece that uses above-mentioned lock washer, described connected piece be provided with described washer face on the groove B that adapts of projection.
The beneficial effects of the utility model:
1) lock washer of the present utility model, have simple in structure, advantage such as cost of production is low, and anti-loosing effect is good, and this lock washer is for convenience detach, uses the bolt assembly of this structure to be repeatedly used.
2) link of the above-mentioned lock washer of use of the present utility model, its simple structure is used with lock washer and can realizes effectively nonvolatil lockingly, and dismounting and assembling are all more convenient.
3) connected piece of the above-mentioned lock washer of use of the present utility model need not to arrange complicated anti-loose structure on this connected piece, the groove B that only needs the projection on setting thereon and the described washer face to adapt can reach desirable anti-loosing effect.
