Nka kimwe mu bintu byingenzi bifatika, imikorere ya screw igira ingaruka itaziguye kwizerwa, kuramba, numutekano wububiko. Kuva kuri microscopique ibikoresho siyanse kugeza kuri macroscopique yubuhanga bukoreshwa, imikorere ya screw ikubiyemo ibipimo byinshi, harimo imiterere yubukanishi, guhuza ibidukikije, no gukora neza. Buri cyerekezo gisaba igishushanyo mbonera no kugenzura.
I. Ibikoresho Byibanze Byibanze: Impirimbanyi hagati yimbaraga n'umutwaro
Imikorere yibanze ya screw nugukwirakwiza no kwikorera umutwaro, bigatuma imiterere yubukanishi bwingenzi mugusuzuma. Imbaraga zingana nimbaraga zitanga umusaruro ugena imikorere ya screw munsi ya axial tension. Kurugero, hejuru - imbaraga zivanze ibyuma (urugero, icyiciro cya 8.8 no hejuru) birashobora kwihanganira imihangayiko ya megapascal amagana kandi bikwiranye na moteri yimodoka cyangwa ibyubatswe mu kirere. Ku rundi ruhande, imbaraga zo gukata, zigira ingaruka ku gutuza kwayo ku mbaraga zinyuranye kandi zikunze kuboneka mu masahani yoroheje. Byongeye kandi, imbaraga z'umunaniro zigena igihe cya screw igihe cyo kwikorera imitwaro. Kurugero, imiyoboro iri mu kiraro igomba kwihanganira amamiriyoni yikizamini kugirango wirinde gutsindwa kwatewe no gukwirakwiza microcrack.
II. Guhitamo Ibikoresho bya siyansi
Urufatiro rwibikorwa bya screw ruri mu guhitamo ibikoresho. Ibyuma bya karubone (nka Q235) biri hasi - igiciro kandi byoroshye kumashini, ariko iranyerera byoroshye kandi bisaba amashanyarazi cyangwa galvanis. Ibyuma bitagira umwanda (nka 304/316) bigera ku kurwanya ruswa bitewe na chromium - nikel alloy passivation ya firime kandi ikoreshwa cyane mubikoresho byubuvuzi ndetse n’ibidukikije byo mu nyanja. Imiyoboro ya Titanium alloy itoneshwa mu nganda zo mu kirere kubera uburemere bworoshye n'imbaraga nyinshi - kugeza kuri -, ariko biragoye cyane kandi bihenze ku mashini. Mu myaka yashize, imigozi ikomatanya (nka karuboni fibre ikomeza plastike) yatangiye gukoreshwa mubikoresho bya elegitoronike kugirango igabanye uburemere no kwanduza.
III. Inzitizi niterambere muguhuza ibidukikije
Ibidukikije bikabije bishyira ibyifuzo byihariye kumikorere ya screw. Mubushyuhe bwo hejuru - (nka sisitemu yo gusohora moteri), imigozi igomba kuba ikozwe mubushyuhe - ibyuma birwanya (nka Inconel 718), bifite okiside irenze dogere 800. Mugihe gito - ahantu hashyuha (nkibigega bya gaze ya gaze isanzwe), ibyuma bisanzwe bizavunika kubera inzibacyuho yoroheje, bisaba ko hakoreshwa ibyuma bya austenitis bitagira umuyonga cyangwa nikel -. Kurwanya ruswa yimiti, usibye gusya kwa gakondo, gutwikira Dacromet cyangwa gutera PTFE (Teflon) birashobora kongera imbaraga zo kurwanya umunyu.
IV. Uburinganire bwa Geometrike nibikomoka kumikorere
Urudodo rwuzuye neza (urugero, urwego rwo kwihanganira ISO), imiterere yumutwe (hexagon sock / ikiruhuko cyambukiranya), hamwe no kuvura hejuru bigira ingaruka muburyo bwo guteranya no kwagura imikorere. Kurugero, kwikorera - gukanda, bitewe nigishushanyo cyihariye cyabigenewe, birashobora kwinjira mubikoresho bya pulasitike (nk'urupapuro rwa pulasitike cyangwa ruto rwa aluminiyumu), bikuraho ibikenerwa mbere yo gucukura -. Gufunga imigozi (nka insimburangingo ya nylon cyangwa isabune yo gukaraba) irinda kugabanuka kubera kunyeganyega binyuze mukurwanya guterana amagambo. Hamwe niterambere ryerekeza kuri miniaturizasi, imiyoboro yubuvuzi irashobora kugera kuri diametero iri munsi ya 1mm, bisaba tekinoroji ya micromachining kugirango ibe ihamye.
V. Icyerekezo kizaza: Ubwenge no Kuramba
Hamwe niterambere ryinganda 4.0, imiyoboro yubwenge itangiye gushiramo ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bikurikirana. Imiyoboro ya biodegradable (nk'iyakozwe muri magnesium alloys) igenda isimbuza buhoro buhoro ibyuma byatewe mu kubaga amagufwa, birinda kubagwa kabiri. Muri icyo gihe, kugabanya imikoreshereze yibikoresho hifashishijwe igishushanyo mbonera cya topologiya cyangwa gukoresha ibyuma bitunganyirizwa hamwe byabaye intego nyamukuru yo gukora icyatsi.
Nubunini bwazo, screw nizo zitagaragara zifatizo za sisitemu ya mashini. Kunoza imikorere yabo ntibishingiye gusa ku ntambwe imaze guterwa mu ikoranabuhanga rimwe ahubwo binashingira ku guhanga udushya mu bumenyi butandukanye, harimo ibikoresho bya siyansi, ibishushanyo mbonera, hamwe n’ubuhanga bwo hejuru. Muburyo bugezweho kandi busaba porogaramu, buri bwihindurize bwimigozi isunika imipaka yubushobozi bwubwubatsi bwabantu.
