Zvese zvinosungirira zvinouya zvine mavara chaiwo pamisoro yavo izvo zvinobatsira mukuziva kwaakabva, zvinhu, uye saizi. Vagadziri veFastener vane basa rekuona pachena kuzivikanwa kwezvigadzirwa zvavo kune vatengi. Gwaro iri rinopa ruzivo runobatsira kukubatsira kuti unzwisise uye kududzira mamaki aripo pane zvinosungirirwa.

Yese yekusimbisa inogadzirwa nekambani inodiwa kutakura yakasarudzika identifier mumusoro wayo. Izvi zvinogona kungosanganisira zvinyorwa zvekambani kana zita. Iyi tsika yakaitwa inosungirwa neFaster Quality Act kuisa chivimbo muvatengi kuti vari kutenga kubva kumugadziri akavimbika.

Fastener Standards

Kudyidzana kwenyika dzese pakati pemakambani kwatungamira mukugadzwa kweakamisikidzwa mamakisi ezvimisikidzo. Aya mazinga anovhara kuumbwa kwezvinhu, zviyero, kushivirira kwedimensional, uye machira, achipa ruzivo rwakakwana nezvechisungo chimwe nechimwe.

Sangano reAmerican Society for Mechanical Engineers (ASME) rinopa gwaro reASME B1.1, iro rinotaura zvinodiwa patambo dzakabatana inch screw. ASME inogamuchirwa zvakanyanya seyero nemakambani mazhinji.

Mamwe mazinga anotsanangura magiredhi ekusimbisa zvichienderana nezvinhu uye zvemuviri zvimiro. Semuenzaniso, SAE J429 inotsanangura zvinodikanwa zveGiredhi 2, Giredhi 5, uye Giredhi 8 fasteners. Kuziva giredhi regiredhi rinopa ruzivo nezve zvinhu zvayo, kuomarara kwemhando, electromechanical zvimiro, uye kuti inonamatira inch kana metric standard.

Mienzaniso yeSAE J429 Grade 2, Grade 5 uye Grade 8

Sosaiti yeMotokari Engineers (SAE) yakagadzira iyo SAE J429 chiyero cheMechanical uye Material Zvinodiwa zveMechanical Fasteners. Iyi chiyero inoraira michina uye zvinhu zvivakwa zve inch bolts, screws,studssems, uyeU-mabhaudhi, inovhara zviyero kusvika 1-½” muhupamhi. Kuwedzera kwegiredhi refastener kunoratidza kusimba kwepamusoro, kunowanzo kuratidzwa nemitsara yeradial kumusoro kwechisungiso.

Ziva kuti Giredhi 2 reSAE J429 rinogona kushaya mamaki. Zvakare, mamakisi emugadziri anogona kugadziridzwa pamusoro pechitsigiro kuti zvienderane nechimiro chegiredhi racho.
