Kuti uve nechokwadi chekuchengetedza uye kuvimbika, zvakakosha kuti usarudze giredhi rakakodzera uye kuisirwa kwakaringana kuti uve nechokwadi chekuchengeteka kwako pamushini.
Mhando huru dzemabhoti uye screws dzakagadzirwa neinch uye metric simbi inoratidzwa mutafura 1 (ona pazasi).
Mabhaudhi esimbi akapfava (anozivikanwawo segiredhi 2 kana metric 5.8) ane simba rekusimba rinoita 385 MPa. Simba rehumbowo ndiwo mutoro unokwanisa kumira nechisungo pasina deformation yekusingaperi (kukuvadza kusingadzoreki). Simba rakavimbiswa rekirasi 5 mabhoti ndeye 600 MPa, uye simba rakavimbiswa rekirasi 8 mabhoti ndeye 840 MPa. Nokudaro, zviri nani kirasi yebhoti, iyo yakakura mutoro inogona kumira, ichiramba yakanyunguduka. Kana mutoro wacho wabviswa, mabhaudhi emhando yepamusoro anodzokera kuhurefu hwawo hwepakutanga uye anoramba ari elastic, nepo hurombo husina kunaka mabhoti anogona kuita purasitiki uye kutambanudza zvachose.
Mazhinji mainjiniya anoshandisa chikamu che60% kuverenga simba rekugera rebhaudhi, saka uyu ndiwo mutemo unobatsira wechigunwe pakusarudza saizi chaiyo uye kirasi yesimba rekugera. Ini ndinofunga zvakanaka kutaura kuti mota zhinji dzakagadziridzwa dzakagadziridzwa maererano nehukuru hwekutsanya, uye kazhinji yenguva haina kuchengetedzeka, asi inogona kuita kuti zvinhu zvitaridzike serori mune dzimwe nguva. Zvibatiso zvidiki zvinogona kupinza muchina unopinza, asi sekutaura kwakamboitwa nemumwe wavadzidzisi vangu, hakuna murimi anotenga tirakita kana yakavakwa kusvika painogumira nekuti inoratidzika kunge isina simba zvekusimudza. Zvakadaro, mumotokari dzemazuvano tave kuona kushandiswa kwemamoiri madiki - saka zviri kwauri! Mazhinji ma modifiers anoshandisa socket head fasteners ari giredhi 8 mhando.
Kana saizi yakakodzera yekusungirira yasarudzwa, kusarudzwa kwegiredhi kunofanirwa kuve kwakavakirwa pachiyero pakati pesimba rekusimba, ductility uye kuoma. Kusimba kwesimba ndiro simba rekupedzisira rezvinhu izvo fastener inogadzirwa. Ductility ndiyo dhigirii iyo chisungo chinotambanudzwa chisati chatadza. Kusimba kunoreva kuneta kuramba uye kugona kutsungirira mitoro yecyclic.
Saka, kuziva izvi chokwadi nezve simbi yemuviri, zvinova nyore kusarudza iyo chaiyo bhaudhi giredhi.
Pabhaudhi rebhandi rechigaro, tinoda bhaudhi rinopfakanyika iro rinogona kutatamuka zvakanyanya risati ratadza, ipapo kuvhunduka kwapera uye mutakuri aponeswa. Saizvozvo, mabhandi echigaro anchorages ari mukirasi yakapfava uye haifanirwe kutsiviwa nemabhaudhi akasimba anosvika pakakwirira mitoro uye anongoerekana atadza. Saizvozvo, kune mafender, tsoka dzetsoka, firewall mounts, uye zvimwe zvisinganyanyi kuomeserwa zvisiri-akakosha maapplication, Kirasi 2 kana unclassified fasteners inogona kushandiswa.
Ini ndinowana makirasi 5 mafasteners (8.8 metric) kuti akwane chero zvimwe zvese pamota yakagadziridzwa. Ivo vane kirasi 8 bolt tensile simba asi hapana brittleness. Mukumiswa vanozomira cyclic mitoro, mune mamwe maapplication vanopa shear uye clamp simba pasina kupera simba nekuda kwe ductility kana pamusoro kuomesa.
Kune dzakakosha injini yekushandisa senge silinda musoro mabhaudhi uye akasiyana kits, kirasi 8 mabhaudhi ane chaiyo torque yekuisa preload majoini ekusungirira ane mashoma bhaudhi kutambanudza ndiyo sarudzo yakanyanya kunaka.
Nuts anowanzo kugadzirwa kubva munyoro kana munyoro simbi, yakafanana nekirasi 2 mabhaudhi. Zvinoshamisa sezvingaite senge, kureba uye shinda dhizaini yenati inotemwa kuitira kuti bhaudhi riwane simba rakazara pasi pemutoro. Izvi zvinoreva kuti kana iwe ukasimbisa chisungo, kazhinji unobvisa nati kutanga, uchisiya bhaudhi.
Kana iwe ukaomesa chisungo kune zvakatemwa, iwe unoisa preload inopikisa mutoro kune yakapesana uye zvakare inoremedza chisungiso kuitira kuti iyo yakawedzerwa mutoro usatambanudze chisungo uye iite kuti isununguke.
Kusungirirwa kwakakodzera kwezvose zvinosungirirwa pamotokari kwakakosha zvikuru, asi munzvimbo dzisinganyanyi kukosha, ruzivo uye mawrench akajairika anogona kushandiswa pane izvi. Wrenches akagadzirirwa chaiwo fastener saizi; iyo yakakura chisungo, iyo yakareba iyo wrench ichave yekupa iyo torque chaiyo kubva "standard" simba remunhu. Imi mose munorangarira kuti mudzidzi anogara achityora kota-inch screws kusvika aziva kuti zvidiki zvidiki zvinoda kusunungurwa.
Nylon nzungu dzakajairika mumagadzirirwo etiramu zvekuti dzakatsiva zvakanyanya mawashi echitubu echinyakare. Ivo vanoshanda zvakanyanya mukushandisa uko vibration kana kutenderera zvinhu zvakakosha uye zvakare uko kugadzirisa kwakaoma. Iva nechokwadi chekuti tambo imwe chete inopinda nepakati kuitira kubatana kwakakodzera. Usashandise purasitiki yenaironi kana kupisa kuchinyungudutsa zvisungo zvenaironi, uye usashandise zvakanyanya mushure mekusunungura kanopfuura kaviri.
