Bolt ekilasini amandla: wokugubha, GOST ne torque

Ngo zokukhiqiza lanamuhla isebenzisa sebuningini timphawu tesakhiwo, ngalinye elikwazi wenza umkhiqizo wokugcina umsebenzi othize, ngokuvamile kubaluleke kakhulu. Ngakho-ke, omunye izinjongo ekuklanyweni kanye womshini eziyinkimbinkimbi esiyinhlanganisela izakhiwo iba kokungathembeki okunokwethenjelwa phakathi izingxenye.

Injongo usebenzisa ibhawudo

Zikhona ongakhetha eziningi ukuxhuma imikhiqizo ezimbili, ezifana Welding, nokunamathisela ngomthofu, kunenze nisondelane, ukusetshenziswa izipikili. Nokho, benayo ezivamile futhi ngempela ethile abalulekile - ungomunye-piece. Okuningi ngokunembile, separable Nokho, ezingxenyeni ezihlukene kufanele deform kubo, usike nokunye.

Kulula kakhulu ukusebenzisa njengoba fastener kufaneleka, ngiphakamisa zangaphambi ekilasini wamandla umshudo kuye umthwalo ziwumthwalo inhlangano.

Indikimba esetshenziswa cishe zakho konke ukwakheka ukuthi kancane more xaka ithisipuni abavamile. Cabanga imoto ukuthi akukho kwesondo eyodwa. Ngakho ukuthi kukhona imoto - e ithoyizi kwengane, isakhiwo isigaba amandla okuyinto ephansi kakhulu, namanje ngeke akwenze ngaphandle izakhi threaded.

Izinzuzo uxhumano threaded

Naphezu kweqiniso lokuthi ngezinye izikhathi torque engu esikhulu ayikuvumeli nethutshana uyasikrufulula nut, umshudo, usenayo eziningi eziwusizo phezu kwezinye izindlela yasibamba:

1. uxhumano High nokwethenjelwa, yizinhlobonhlobo iphrofayela lavula imethrikhi noma yimuphi omunye ngentambo. Iphrofayela sibonga athuthukiswe izifundo eziningi, ngoba ukumelana imithwalo esindayo ivikelwe kusuka self (nakuba kuyodingeka ukhethe elungile kokuqina torque engu).
2. Ubulula yokuhlangana kanye disassembly kwezakhiwo. Ilungiselelwe ukusetshenziswa elinobunye inkonzo ithuluzi - amabhowudu ukhiye, engesiyo, isibonelo, ashiselwe noma riveted ukuxhumana.
3. Ukukwazi ukuqamba Axial ezinkulu futhi ilayisha transverse. amandla umshudo ibalwa kokubili isiqondiso longitudinal futhi transverse. ngezinto zokwakha zesimanje kanye nobuchwepheshe enze kube nokwenzeka ukuba unciphise inani iziqobosho esetshenziswa futhi sinciphise ubukhulu bayo.
4. izindleko okuphansi, ikakhulukazi uma kuqhathaniswa izindleko ukuthengwa Welding izinto nemisebenzi.

Phakathi zezakhi amaphutha - emakamu ukucindezeleka impande ngentambo. Ngakho-ke, i-uhlobo oluthile ukwakhiwa Kufanele kukhethwe ekilasini wamandla umshudo kahle ngokuhambisana umthwalo isicelo. Futhi, ukuqinisekisa ukuthembeka uxhumano threaded kuwufanele ukukhumbula ukusetshenziswa uvala izindlela, ezifana entwasahlobo washers noma amantongomane yokuvala.

Izinhlobo ukuxhumana yangaphakathi

Ukuze uxhumano isikulufa, lapho kudingeka wenze kunye ngentambo yangaphakathi, kanti eyesibili - Ingaphandle. Lezi zilwane ezintathu ingasetshenziswa kuncike tesakhiwo:

1. Intulo uxhumano. Kulokhu, indima nati (ingxenye ngentambo yangaphakathi) wenza ingxenye indawo. It is kuqala yamba imbobo. A ngentambo is zizosetshenziswa. Ukuze neminye imininingwane sisetshenziswa imbobo bushelelezi isiyingi, ngemva kwalokho screw edonswa.

2. Bolt. Lapha, konke kulula kakhulu futhi eziqinile: nezingxenye ezimbili exhunyiwe bushelelezi yamba izimbobo kuzo afakwa umshudo, futhi ohlangothini reverse - nut.

3. izikopelo, komunye umkhawulo okuyinto screwed ku engeyokuqala lento, kanti eyesibili - nut is screwed.

Bolt ekilasini amandla

Njengoba kuphawuliwe ngenhla, iziqobosho kumele ifaniswe kahle. Akukho umqondo esiku amathuluzi inkonzo Uhlaka Racks ukusebenzisa izingxenye insimbi engagqwali. Ngesikhathi esifanayo, e ezithile flange ukuxhumana (isib kokuqina izingxenye multi-ton of izakhiwo steel) kuyadingeka ukusebenzisa izinto nge ngcono izici lokukhanda.

Ngokuvamile, isigaba wamandla umshudo (GOST 1759.4-87) - iqoqo izici mechanical, okuyinto sihlanganisa ukumelana yesikhashana, amandla umngcele, ngenzuzo elinganiselwe nokunwebeka ngemva ukwa, nobulukhuni indaba, futhi kwezinye izimo ngisho ubunzima. Ngokuvamile, leligama ipharamitha usebenzisa izinombolo ezimbili ahlukaniswe isikhathi. Eyokuqala wabo, ngemva ukubuyabuyelela nge 10 libonisa nesikhathi ukumelana ubuncane, kanti owesibili, futhi kwenyuke ngo izikhathi 10, ikhombisa Ingxenye etholwe sokuhlukanisa amandla isivuno kokwaziswa amandla eqine. Umkhiqizo kwalezi zibalo ofanayo ezimbili zibonisa ukubaluleka esiphansi amandla isivuno. Ikilasi wamandla umshudo kuqukethwe kophawu salo, esiwulwazi kanje: M12h1,25h60.58 lapho 58 - efanayo inombolo enamadijithi amabili.

kokuqina

Ukuze ngokuphepha ubambe izakhi isikulufa uxhumano yokwakha, kufanele siqaphelisise umzamo (isikhathi) kokuqina. Ngakho, cabanga isimo lapho i "umakhenikha" ongenalwazi ngokokuqala ngqá ekwindla ngaphansi hood siqu imoto yakho entsha sha nokuzama ngangokunokwenzeka ukuze ukunqanda nut noma isikulufa. Konke lokhu kungaholela esimweni sokuqala, nje ungakhululekile Osebenza ishizolo, kanti eyesibili - by Drilling imbobo sikebhe. Lokhu kungenxa torque engu ngokungalungile abakhethiwe. Abanolwazi imoto Mechanics, repairmen kanye nje abe "esakhelwe isandla" dynamometer. Kodwa saqala kungcono ukusebenzisa isikrufu torque engu noma amabhowudu emoyeni umthelela, iziphi ubukele kuya torque engu ethize.

Indlela uyasikrufulula "eziyinkimbinkimbi" umshudo

Ake sithi qinisa zonke kwenzeka. Kodwa isikhathi sihamba, futhi udinga uyasikrufulula iziqobosho futhi. Ngenxa ukugqwala ukwenza kube ngezinye izikhathi akulula kakhulu, futhi amandla ephezulu ikilasi kwebhowudu asisho londoloza ke ekubhujisweni. Ngakho-ke kufanele bakhumbule izindlela ezimbalwa ezilula ukuthi lula unwinding:

1. Ukuze uqale, kufanele usebenzise "VeDeshkoy". Ukwakheka kuyasiqeda ungqimba ukugqwala.

2. Ngomusa badonsa nut ngesando ukuze aphule nokugqwala Ukuphrofayela ngentambo.

3. Ungazama crank up a degrees ambalwa bebheke kokuqina nut bese unscrewed.

Kubalulekile ukuba nesineke, njengoba kungenzeka uhlale nge nut noma isikulufa ikhanda e ukhiye.
