Tuvuze amashanyarazi ya nyundo yamashanyarazi, reka tubanze twumve inyundo y'amashanyarazi niki?
Inyundo y'amashanyarazi ishingiye ku myitozo y'amashanyarazi kandi ikongeramo piston hamwe na crankshaft ihuza inkoni itwarwa na moteri y'amashanyarazi.Ihagarika umwuka inyuma n'inyuma muri silinderi, itera impinduka zigihe cyumuvuduko wumwuka muri silinderi.Mugihe umuvuduko wumwuka uhinduka, inyundo isubira muri silinderi, bihwanye no gukoresha inyundo kugirango uhore ukanda bito bizunguruka.Imyitozo yo ku nyundo irashobora gukoreshwa kubice byacitse kuko bitanga umuvuduko wo gusubiranamo byihuse (ingaruka zikunze kugaragara) kumuyoboro wimyitozo uko bizunguruka.Ntabwo bisaba imirimo myinshi yintoki, kandi irashobora gucukura umwobo muri beto ya sima namabuye, ariko ntabwo ari ibyuma, ibiti, plastike cyangwa ibindi bikoresho.
Ikibi ni uko kunyeganyega ari binini kandi bizatera urwego runaka kwangirika ku nyubako zikikije.Kubyuma byuma muburyo bwa beto, bits zisanzwe zidashobora kugenda neza, kandi kunyeganyega bizana umukungugu mwinshi, kandi kunyeganyega nabyo bizana urusaku rwinshi.Kunanirwa gutwara ibikoresho bihagije birinda birashobora kubangamira ubuzima.
Imyitozo ya nyundo ni iki?Birashobora gutandukanywa hafi yubwoko bubiri: SDS Plus na Sds Max.
SDS-Yongeyeho - Imyobo ibiri hamwe na grooves ebyiri zizengurutse
Sisitemu ya SDS yatunganijwe na BOSCH mu 1975 niyo shingiro ryibyinshi mumashanyarazi ya nyundo.Ntibikiri bizwi uko umwimerere wa SDS umwitozo bito wasaga.Ubu sisitemu izwi cyane ya SDS-Plus yatunganijwe hamwe na Bosch na Hilti.Mubisanzwe bisobanurwa ngo "Spannen durch Sisitemu" (sisitemu yihuta yo guhinduranya clamping), izina ryayo ryakuwe mumagambo yikidage "S tecken - D rehen - Umutekano".
Ubwiza bwa SDS Plus nuko usunika gusa imyitozo bito mumasoko yuzuye imyitozo.Nta gukomera gukenewe.Imyitozo ya biti ntabwo ihamye neza kuri chuck, ahubwo iranyerera inyuma nka piston.Iyo bizunguruka, biti bitobora ntibizanyerera muri chuck tubikesha dimim ebyiri zibiri kumurongo wigikoresho.SDS shank drill bits kumyitozo yo ku nyundo irakora neza kuruta ubundi bwoko bwimyitozo ya shank bitewe na shobuja zombi, bigatuma inyundo yihuta cyane kandi ikanoza inyundo.By'umwihariko, inyundo ya nyundo ikoreshwa mu gucukura inyundo mu mabuye na beto irashobora kwomekwa kuri sisitemu yuzuye ya shank na chuck yakozwe kubwiyi ntego.Sisitemu yo kurekura byihuse SDS nuburyo busanzwe bwo kugerekaho inyundo zomunsi.Ntabwo itanga gusa inzira yihuse, yoroshye kandi yumutekano yo gufunga bito, iranatanga uburyo bwiza bwo guhererekanya ingufu kuri biti ubwayo.
SDS-Max - Igikoresho cya bitanu kizengurutse
SDS-Plus nayo ifite aho igarukira.Mubisanzwe, umurambararo wa diameter ya SDS Plus ni 10mm, bityo gucukura umwobo muto kandi wo hagati ntabwo ari ikibazo.Iyo ucukura umwobo munini cyangwa wimbitse, urumuri rudahagije rushobora gutuma imyitozo ya biti ifata kandi ikiganza kimeneka mugihe cyo gukora.BOSCH yateje imbere SDS-MAX ishingiye kuri SDS-Plus, ifite ibinono bitatu nibyobo bibiri.Igikoresho cya SDS Max gifite ibice bitanu.Hano haribintu bitatu bifunguye nibice bibiri bifunze (kugirango wirinde imyitozo bituruka hanze).Mubisanzwe bizwi nkibisumizi bitatu nibyobo bibiri bizengurutse, bizwi kandi nkibyobo bitanu.Igikoresho cya SDS Max gifite umurambararo wa mm 18 kandi gikwiranye nakazi gakomeye kuruta SDS-Plus.Kubwibyo, ikiganza cya SDS Max gifite torque ikomeye kuruta SDS-Plus kandi irakwiriye gukoreshwa ningaruka nini ya diameter yibikorwa bya binini kubikorwa binini kandi byimbitse.Abantu benshi bigeze kwizera ko sisitemu ya SDS Max izasimbuza sisitemu ya kera ya SDS.Mubyukuri, iterambere nyamukuru muri sisitemu nuko piston ifite inkoni ndende, iyo rero ikubise bito, ingaruka zirakomera kandi biti bigabanya neza.Nubwo kuzamura sisitemu ya SDS, sisitemu ya SDS-Plus izakomeza gukoreshwa.SDS-MAX ya 18mm ya diametre ya shank itera ibiciro byinshi mugihe utunganya ingano ntoya.Ntibishobora kuvugwa ko ari umusimbura wa SDS-Plus, ahubwo byuzuzanya.Inyundo n'amashanyarazi bikoreshwa muburyo butandukanye mumahanga.Hariho ubwoko butandukanye bwimikorere nibikoresho byimbaraga kuburemere butandukanye bwinyundo hamwe nubunini bwa drill.
Ukurikije isoko, SDS-plus niyo isanzwe kandi mubisanzwe yakira bits ya drill kuva kuri mm 4 kugeza kuri mm 30 (5/32 muri. Kugeza 1-1 / 4 muri.).Uburebure bwose 110mm, uburebure ntarengwa 1500mm.SDS-MAX isanzwe ikoreshwa mubyobo binini no gutora.Imyitozo yingirakamaro isanzwe iri hagati ya 1/2 cm (13 mm) na 1-3 / 4 cm (44 mm).Muri rusange uburebure buri hagati ya santimetero 12 na 21 (300 kugeza 530 mm).
