DIN985 simbi isina tsvina anti kusunungura nati hexagonal yekuzvivharira nati 304 nzungu naironi anti kutsvedza sikuruu chivharo chisiri-metallic

Anti loosening nut yakabva kunze kwenyika. Iyo inonamirwa zvachose kune shinda neakakosha einjiniya epurasitiki, izvo zvinoita kuti simba rekuita rakasimba rigadzirwe kana ipurasitiki yeinjiniya inodzvanywa panguva yekuomesa tambo yemukati nekunze, ichiwedzera zvakanyanya kupokana pakati petambo dzemukati nekunze uye kupa zvachose kuramba vibration. Kupikisa uku kwakagovaniswa zvachose mukati mechikamu chese chekubatana chemukati nekunze tambo, uye iyo frictional force inozvimiririra nekusimbisa kumanikidza pakati pemukati nekunze tambo. Kusiyana neyakapfuura anti backlash nzira, inotsamira pane frictional force inogadzirwa nekumanikidza mushure mekunge screw yasimbiswa kudzivirira backlash. Kana screw yangosunungurwa zvishoma uye kudzvanywa kwadzikira, simba rekupokana rinokurumidza kunyangarika uye rinorasikirwa neayo anti backlash effect, zvichiita kuti screw isununguke. Nekudaro, iyo yepurasitiki anti kusunungura nzira inokanganiswa nenharaunda uye haigone kuzadzisa zvinodiwa zvekupisa kwakanyanya uye kutonhora kwakanyanya. Izvo zvinodikanwa kuti uongorore itsva anti loosening tekinoroji. Anti kusunungura nzungu dzakagadzirwa muUnited States makore makumi matatu nemashanu apfuura, iine 30 madhigirii wedge pamusoro pechinyakare 60 degree zino tip. Chimiro ichi chinobvumira bhaudhi kuti riwane kupokana kukuru pakati petambo dzechirume nedzechikadzi mushure mekusunga nati, ichiwana anti kusunungura zvichienzaniswa netambo dzechinyakare. Nekuda kwekuchinja kwekona yechimiro chezino, simba rakajairwa rinogadzirwa nekubatana pakati peshinda rinogadzira 60 degree angle ine bolt axis, pachinzvimbo che30 degree angle inoonekwa neshinda dzenguva dzose. Iyo yakajairwa dzvinyiriro yeshinda yakakura zvakanyanya kupfuura yekusimbisa yekusimbisa, saka iyo anti loosening friction simba inogadzirwa inowedzerwa zvakanyanya. Kana shinda yechirume ichibatanidzwa neshinda yechikadzi, zino rezino pacrest rinowanzoita deformation, zvichiita kuti mutoro ugoverwe zvakaenzana pamusoro pehurefu hwese hwemutsara wekutenderera pakubata, kudzivirira chiitiko apo inopfuura 80% yemutoro wakazara inonangidzirwa pane shinda dzemazino ekutanga neechipiri panguva yakajairwa tambo yekubatanidzwa. Naizvozvo, tambo yekubatanidza haingokunda iyo yakashata yekuzvisunungura zviri nyore pasi pe vibration mamiriro eyakajairwa yakajairika coupling, asi zvakare inowedzera hupenyu hwayo hwesevhisi. Nekuda kweiyi yakakosha mazino deformation anti kusunungura nzira, inogona kupatsanurwa kashanu kusvika ka50 kakawanda, uye anti kusunungura basa richiri kuenderera. Nekuda kweiyo yakakwira anti vibration, huremu, uye inodzokororwa disassembly, iyi anti kusunungura nzira yave yakavimbika anti kusunungura chigadzirwa nhasi. Zvikururu zvakamboitwa anti loosening treatment zvinodaidzwa kuti anti loosening screws, ayo anonyanya kukodzera kusungirira zvikamu zvinofamba. Dzakatanga kushandiswa pazvitundumuseremusere zvekuAmerica uye gare gare dzakasimudzirwa kuindasitiri yekugadzira mota yekuAmerica. Nekukura kwehunyanzvi hwekugadzira uye kudzikiswa kwemitengo, anoshandiswa zvakanyanya mumaindasitiri mazhinji akadai se3C, mabhasikoro, ice skating uye skiing zvishandiso, fenicha, zvemitambo, midziyo yekurapa, nezvimwewo, kutsiva zvizere echinyakare anti loosening washers uye achiratidza zvizere kuvimbika kwekutsanya uye kusasununguka mhedzisiro ye anti kusunungura screws.
