I. Isishwankathelo Esiqhelekileyo: Ilitye Lembombo Yeetyhubhu Ezingenamthungo Ezitsalwa Ngobandayo ZaseRashiya

I-GOST 8734-75(isihloko esipheleleyo: Iityhubhu zentsimbi ezingenamthungo ezikhubazekileyo. Uluhlu) yiRashiya (yangaphambili i-USSR)umgangatho onobukhulu/wokwahlukahlukakwiityhubhu zentsimbi ezingenamthungo ezitsalwa ngokubandayo okanye eziqengqelekayo ngokubandayo. Yaqala ukusebenza ngomhla woku-1 kweyoMqungu 1977. Lo mgangatho ugubungela iityhubhu ezingenamthungo ezenziwe ngokubandayo (eziveliswa ngokuqengqeleka okubandayo okanye ukutsalwa okubandayo) ngeububanzi obungaphandle be-1 mm ukuya kwi-200 mmkwayeubukhulu bodonga ukusuka kwi-0.2 mm ukuya kwi-22 mm.

Inkqubo yokutsala/ukuqengqeleka okubandayo inika iityhubhu ukuchaneka okuphezulu kakhulu kunye nomgangatho ogqwesileyo womphezulu. Ngokuguqulwa okubandayo, iinkozo zentsimbi ziyacocwa, kwaye uxinano lwesinyithi kunye neempawu zoomatshini ziphuculwa kakhulu. Le teknoloji yokwenza ubanda ngokuchaneka okuphezulu yenza iityhubhu zibe ngcono kakhulu kuneetyhubhu eziqhelekileyo eziqengqeleka ngokushushu ngokwemilinganiselo yokunyamezelana, ukuqina kunye nokugqitywa komphezulu - okwenza ukuba zilungele izixhobo ezichanekileyo, iinkqubo ze-hydraulic, izakhiwo zoomatshini ezichanekileyo kunye nezinye izicelo ezininzi ezifuna amandla.

Lo mgangatho usekelwe kumgangatho wamazwe ngamazweСТ СЭВ 1483-78kwaye yavunywa yiKomiti yeMigangatho yeSizwe ye-USSR ngomhla we-13 kweyeDwarha ngo-1975 (uMyalelo Nombolo 2604). Uhlelo olusebenzayo lwangoku lushicilelo olutsha luka-2007.

II. Inkqubo eQhelekileyo: Ulwalamano oluHlanganisiweyo phakathi kweGOST 8734 kunye neGOST 8733

Kwinkqubo yemigangatho yaseRashiya,I-GOST 8734-75kufuneka isetyenziswe kunye neenkcukacha zobugcisa ezihambisana nayoI-GOST 8733-87(Iityhubhu zentsimbi ezingenamthungo ezibuthathaka kubanda – Iimeko zobugcisa). Zidibene zakha umgangatho opheleleyo wemveliso yeetyhubhu zentsimbi:

Umgangatho	Ububanzi	Indima
I-GOST 8734-75	Uluhlu lobubanzi bangaphandle, uthotho lobukhulu bodonga, ukunyamezelana okulinganayo, iintlobo zobude kunye nokuphambuka okuvumelekileyo, ubunzima bethiyori	"Ijongeka njani" - ubukhulu
I-GOST 8733-87	Iindidi zentsimbi, ukwakheka kweekhemikhali, iipropati zoomatshini, uvavanyo lwenkqubo, uvavanyo lwe-hydraulic, imithetho yokuhlolwa, ukumakisha, ukupakisha	"Ziziphi izinto kwaye ziqine kangakanani" - iimfuno zobugcisa

Inqaku lokuthenga: Kumaxwebhu obunjineli okanye kwiiodolo zokuthenga,I-GOST 8733 kunye ne-GOST 8734 phantse zihlala zicatshulwe kunye– benza isibini esingenakwahlulwa.

III. Uluhlu lweeDimensional kunye noHlelo

3.1 Uluhlu lwemilinganiselo

Umgangatho we-GOST 8734-75 ugubungela la manqanaba alandelayo:

Ipharamitha	Uluhlu
Ububanzi obungaphandle	1 – 200 mm
Ubukhulu bodonga	0.2 – 22 mm
Ubude (ngokungacwangciswanga)	1.5 – 11.5 m
Ubude (buzinzile)	4.5 – 9 m(ukuphambuka komda +10 mm)

3.2 Uhlulo ngokobukhulu bodonga

Ngokusekelwe kumlinganiselo wobubanzi bangaphandle (D) nobukhulu bodonga (iityhubhu), iityhubhu zahlulwe zibe ziindidi ezine:

Udidi	Umlinganiselo we-D/s	Inkcazo
Udonga olubhityile kakhulu	D/s > 40	Ilula kakhulu, yezicelo zokonga ubunzima
Udonga olubhityileyo	D/s = 12.5 – 40	Iityhubhu eziqhelekileyo eziludongeni olubhityileyo
Udonga oluqinileyo	D/s = 6 – 12.5	Umthamo ophezulu wokuthwala uxinzelelo
Udonga olutyebileyo kakhulu	D/s < 6	Usetyenziso oluxinzelelekileyo

3.3 Ukunyamezelana kobubanzi obungaphandle

Uluhlu lobubanzi obungaphandle (mm)	Ukuphambuka okuvumelekileyo (mm)
4 – 10	± 0.15
>10 – 30	±0.30
>30 – 50	± 0.40
>50	± 0.8%

3.4 Ukunyamezelana kobukhulu bodonga

Uluhlu lobukhulu bodonga (mm)	Ukuphambuka okuvumelekileyo
≤1.0	± 0.12 mm
>1.0 – 5.0	± 10%
>5.0	± 8%

3.5 Iimfuneko zokuthe tye

Uluhlu lobubanzi obungaphandle (mm)	Ubukhulu begophe ngobude bemitha nganye
4 – 8	≤ 3 mm
>8 – 10	≤ 2 mm
>10	≤ 1.5 mm

Phawula: Kwiityhubhu ezinobubanzi obungaphandle obuyi-20-90 mm, imfuneko yokuthe tye engqongqo ye≤ 1 mm ngobude bemitha nganyekunokuvunyelwana ngako.

IV. Ukubalwa kobunzima bethiyori

I-GOST 8734-75 isebenzisa le fomyula ilandelayo ukubala ubunzima bethiyori ngemitha nganye yetyhubhu:

M = 0.02466148 × s × (Dₙ − s)

Apho:

M= ubunzima ngemitha nganye (kg)

Dₙ= ububanzi obuqhelekileyo bangaphandle (mm)

s= ubukhulu bodonga (mm)

Uxinano lwentsimbi= 7.85 g/cm³

Isihlomelo esiqhelekileyo sinika iitafile zobunzima ezipheleleyo kuzo zonke iindibaniselwano zobubanzi bangaphandle kunye nobukhulu bodonga ukusuka kwi-0.3 mm ukuya kwi-24 mm. Imizekelo:

Kwi-30 mm OD × 2.5 mm udonga, ubunzima bethiyori ≈ 1.696 kg/m

Kwi-76 mm OD × 4.0 mm udonga, ubunzima bethiyori ≈ 7.102 kg/m

V. Amanqanaba eNsimbi afumanekayo

Ngokwe-GOST 8733-87 esemgangathweni ohambelanayo, iityhubhu ezingenamthungo ezitsalwa ngokubandayo zinokwenziwa ngeendidi ezahlukeneyo ze-carbon kunye ne-alloy steel:

Ibanga lentsimbi	Uhlobo	Isicelo esiqhelekileyo
Ibanga le-10, Ibanga lama-20	Intsimbi yesakhiwo sekhabhoni ekumgangatho ophezulu	Ukuhanjiswa kolwelo, izakhiwo ngokubanzi
Ibanga lama-35, Ibanga lama-45	Intsimbi yesakhiwo sekhabhoni ekumgangatho ophezulu	Ukwenziwa koomatshini, iindawo zokwakha ezinamandla aphezulu
09Г2С (09G2S)	Intsimbi engasebenzi kakuhle	Inkonzo yobushushu obuphantsi, izakhiwo ezinamandla aphezulu

Ukulingana kwamazwe ngamazwe: Iityhubhu ze-GOST 8734-75 ezitsalwa ngokubandayo ezingenamthungo zifana kakhulu xa zisetyenziswa kwaye zisetyenziswaI-ASTM A519(iityhubhu zoomatshini zekhabhoni engenamthungo kunye nentsimbi ye-alloy).

VI. IiNdawo zeSicelo eziqhelekileyo

Enkosi Kuukuchaneka okuphezulu, ukugqitywa komphezulu okugudileyo kunye nokugxila okuhle kakhulu, Iityhubhu ezingenamthungo ezitsalwa ngokubandayo zeGOST 8734-75 zisetyenziswa kakhulu kwezi:

Intsimi yesicelo	Ukusetyenziswa okuthile	Kutheni kukhethwe
Oomatshini abachanekileyo	Iishafti ezichanekileyo, iisilinda ze-hydraulic, izinto ze-pneumatic	Ukuchaneka okuphezulu, ukugxila okuhle
Iinkqubo ze-hydraulic kunye ne-pneumatic	Imibhobho yeoyile enoxinzelelo oluphezulu, imigca ye-pneumatic	Umphezulu ongaphakathi othambileyo, ukumelana nokuhamba kwamanzi okuphantsi
Ishishini leemoto	Iityhubhu zokufunxa uthuko, iityhubhu zegiya yokuqhuba	Ukufana okulinganayo okulinganayo
