Hariho impamvu nyinshi abantu bagura igare. Utitaye ku ntego yibi, uburyo bwo kugenda nikintu cyingenzi ni amapine gikunze guhinduka. Ni ubuhe buryo n'uburyo bwo kubihitamo neza, urashobora kwigira kuri iyi ngingo.
Ibipimo ngenderwaho
Ingano yinziga (rim) ni ikintu gikomeye, kuko biterwa nimpamvu igare rikwiye. Mbere, mugihe cyo guhitamo kuzenguruka ibibyimba, bibanze gusa kurwego rwo hanze rwuruziga, ariko mugihe, umubare munini wabasangira ku isi, kubera urujijo rwavutse. Kugirango byoroshye kugenda muburyo bwamapine kandi uhitemo neza igare ryabo, ryatejwe imbere Gahunda y'ibipimo ihuriweho.
Yatejwe imbere n'umuryango mpuzamahanga usanzwe wa Iso, uzwi kare nka ETRO. Dukurikije iyi sisitemu, ubugari bwapi, imbere no hanze ya runini n'uburebure bitabimenyeshwa.
Ibipimo bishingiye ku mwaka wo kurekurwa, uwabikoze kandi, birumvikana ko yerekeza kuri gare.
Amagare y'abana, abahigi, abahigi hamwe n'imiterere imwe yo kuzinga bafite, nk'ubutegetsi, diameter yo hanze yimibare kuva santimetero 12 kugeza 24. Muri Modeli kubantu bakuru, iyi parameter iri muri santimetero 26-28.
Diameter yimbere ya Rim, cyangwa, nkuko nayo yitwa, diameter ya Lambo nigice cyingenzi kuri Tiro, kuko igomba guhura nubugari bwimbere bwa gare ya gare.
Ingano yimbere, ukurikije ISO, ihujwe neza ntabwo ari diameter yo hanze gusa, ahubwo inafite ubugari. Bishingiye ku ntego ya Tiro, irashobora guhinduka mu buryo bwa MM 18-75.
Hano hari ameza aho ibipimo byapimwe byerekanwe hakurikijwe moderi zamagare zakozwe na moderi zakozwe.
Ku binyabiziga biziga ibiziga bibiri byakozwe mu Bufaransa no mu bindi bihugu bimwe by'Uburayi, hari ameza yo guhuza aho amazina ya diameteri y'imbere n'inyuma, ubugari n'uburebure bifite ubwoko butandukanye.
Kugaragaza bisobanura iki?
Kumenyekanisha ku mapine hafi buri gihe kuruhande.
Akenshi, ibipimo byerekana milimetero. Kumenyekanisha muburyo bubiri, nka 35-559, cyangwa 37-630, bisobanura ubugari n'imvururu y'imbere (rim yo kugwa) ya Tiro. Umubare wambere ni ubugari, na kabiri - diameter.
Rimwe na rimwe, ibimenyetso bifite ubwoko butandukanye, kandi imibare igaragarira muri milimetero gusa, ariko no muri santimetero. Kurugero, guhuza imibare nka 622x19, byerekana diameter yimbere muri milimetero hamwe nubunini bwo hanze bwigice.
Amapine arashobora kandi kurangwa numubare gusa muri santimetero. Reba 24x1 yerekana ko umubare wa 24 ari diameter yo hanze, hamwe numuntu udasanzwe urebye guhuza imibare 1 kandi? Yerekana ubugari bwa tine. Rimwe na rimwe aho kuba integer nigice, ubugari bwerekana muburyo bwumubare udashobora kubandi hamwe ningingo, kurugero, 26x1.75.
Akenshi hariho ikimenyetso cyimibare itatu: 20x1.75x2 cyangwa 28x1 ⅝x1. Muri iki kibazo, umubare wambere ni diameter yo hanze, iyakabiri nuburebure, ariko icya gatatu ni ubugari.
Ku magare yakorewe mu Bufaransa cyangwa ibindi bihugu by'i Burayi, hafashwe ibimenyetso bitandukanye. Ubwoko bwa 650A busobanura ko diameter yo hanze ya Tiro ifite milimetero 650, inyuguti A ni ubugari bwayo. Ariko ibimenyetso nkibi biraboneka byinshi kandi bike kenshi, hamenyekanye neza kuri diameter nubugari byaje kubisimbuza. Uyu munsi biramenyerewe ko amapine yo gusiganwa ku magare ku buryo bukurikira: 650-38C, aho umubare wambere wa diameter yo hanze, umubare uhagaze nyuma yuko hyphena isobanura ubugari bwapi, kandi iyi ruganda ni c) ni ingano yerekana diameter yimbere.
Gupima diameter
Kugirango umenye diameter yinziritse, birakenewe gupima radiyo yacyo ukoresheje roolette. Gupima igare byashyizwe hejuru kandi, bimaze gushyira ahagaragara kaseti ya kaseti muri santimetero nyinshi, yamanuye hepfo kuruhande cyangwa hasi, mbere yo gushyira igice kinini cyegereye umurongo wa axis.
Kugirango umenye diameter yuzuye y'uruziga muri milimetero, ugomba kugwiza ibisubizo bitarenze 10, hanyuma 2.
Urashobora kumenya diameter y'uruziga kandi idafite roulette. Kuri ibi ukeneye Koresha ibiganiro byamabara muburyo bwa rucket hanyuma uhindukire uruziga kugeza kumurongo. Uburebure bwumurongo kuva 1 kugeza kuri kabiri bigabanijwe na π (3.14) kandi, nibiba ngombwa, bisobanurwa muri santimetero, bitandukanya ibisubizo, bitandukanya ibisubizo byabonetse na 2.54.
Nigute wahitamo?
Kugirango uhitemo ipine nshya neza, ugomba kugendagenda, birumvikana, kuranga no kugereranya amakuru hamwe na kantu ivugwa muri bisi ishaje. Guhuza ibipimo bigomba kuba byinshi. Ariko, nkuko imyitozo yerekana, ugereranije mbere yubugari bwa Tiro hamwe nubugari bwimbere.
Kuva muri kiriya kigereranyo cy'izi ngero zombi, ibipimo bibiri byingenzi kubakinnyi b'amagare biterwa: Induru na clutch. Ubugari bwa fagitire yubunini bwimbere bugufasha kugenzura neza igare kumyanya, ihuriro ryinshi ryipine ni ryiza. Ariko ikibabaje, Igare hamwe nubugari nkubwo ni bibi.
Ikigereranyo cyiza hagati yubugari bwapi na kirge yimbere ni 1: 1.5 cyangwa 1: 2, n'indangagaciro zose ziva kuri 1.5 kugeza 2.
Kuri bike cyane hamwe nubugari bwa mm 13 mm, amapine kuva mm 18 kugeza kuri 25 nibyiza guhagarika guhitamo kuri tine hamwe na 23-32 mm.
Kuburyo bworoshye bwimiterere yigihugu hamwe nubugari bwa mm 17, amapine ya mm 25-37 arakenewe mubugari, kandi ingero zifite ubugari bwa mm 28-44.
Icyitegererezo gigenewe gucuka amagare, hamwe na mm 19, amapine ni ubugari bukwiye byibuze mm 28-60. Ku magare akoreshwa mugusiganwa ku magare no gukabya byoroshye, aho ubunini bwa RM ifite mm 20, bukora ubugari bwapiye kuva 28 kugeza 47 mm. Kandi hamwe n'ubugari bwa Rim muri mm 21, ubugari bwa Tiro bizaba muri mm 35-50.
Igare rikoreshwa muri siporo ikabije, hamwe na mm 23, ubugari bw'ipine bugomba kuba mu mva ya 40-50, ubugari bwa mm 44 kugeza kuri 5 47 mm bukwiriye kuri mm 25 mm, ubugari bwa bisi ntabwo ari munsi ya mm 75.
Igomba kwibukwa ko Ipine nke cyane yongera cyane ibyago byo gutobora no kwangiza rim.
Ipine nini cyane izagabanya imigezi kumuvuduko muto, nubwo yagabanutse gato. Iyo impinduka nini cyane ipine irashobora kuganisha ku gusenyuka kuva kuri Rim. Byongeye kandi, Kwambara amapine nkibi bibaho cyane kuruta amahitamo yatoranijwe neza.
Bigira ingaruka guhitamo ubugari bwamapine. Kubaho kw'imigabane. Mugari cyane wiziritse hamwe na rim ifunganye - ntabwo ari byiza guhuza ibikorwa byiza hamwe nubuso, kuva iyo uhinduye imigezi iherereye kuruhande, ntibakora ku buso.
Ibihe bidasanzwe bizakundwa hamwe na Tiro ifunganye hamwe ninzitizi nini.
Mugihe ukora kuzunguruka umugongo rwose guhura nubuso, ariko ubugari budahagije no kubogama bizatera kugaragara ko igare rizajya iburyo cyangwa ibumoso, mukabaho.
Ni ubuhe bukungu bw'ipine y'amagare, reba videwo ikurikira.
