1) Nominal diameter renji uye yakakurudzirwa diamita
Maminitsi asina kujairika emabhawa engoro kubva pamakumi matanhatu kusvika ku50mm, uye iyo yakawedzera yakakurudzirwa madhimoni emabhawa eSimbi ndeye 6, 8, 10, 12, 14, 16, 40, 25, 40, 40, makumi maviri neshanu.
2) iyo inobvumidzwa kutsauka kweiyo nzvimbo yekuisa uye saizi yeiyo ribbed simbi bara
Nhungamiro dzekugadzira dzembabvu dzembudzi dzembudzi dzesimbi dzinosangana nezvinodiwa zvinotevera:
Iyo angle β pakati peiyo transverse mbizi uye axis yebara resimbi haifanire kunge isiri pasi pemadhigirii makumi mana. Pakazosvika angle isiri yakakura kupfuura makumi manomwe emadhigirii, kutungamirirwa kwembabvu dzakatarisana nemativi eshumba simbi inofanira kunge yakatarisana;
Iko kusarudzwa kusarudzika l yeTransverse mabvu hakuzove kwakakura kupfuura 0.7 times the komedhiti yezita reiyo simbi bar;
Iyo kona α pakati porutivi rwemberi rwechipfuva chesimbi uye pamusoro pebara resimbi harizi pasi pemadhigiri makumi matanhatu;
Uwandu hwemapundu (kusanganisira uhu hwakafara hwembambo refu) pakati pemigumo yechidimbu mbichana pamativi maviri ebanga haangaiti 20% yezita remazita rembara resimbi;
Kana iyo yemazwi adhiyuta yebara resimbi harisi kupfuura 12mm, iyo hama yerabhi haifanire kunge iri pasi pe0055; Kana iyo zita rezita rinoti 14mm uye 16mm, iyo hama yehama haifanire kunge iri pasi pe0060; Kana iyo mominal diameter yakakura kupfuura 16mm, iyo hama yehama haifanire kunge iri pasi pe0065. Tarisa nezveEmendix c pakuverengera kwerudzi rwehama.
Mabhebhi emberi anowanzove nemabvu mongororo refu, asiwo pasina mbabvu refu.
3) kureba uye kubvumidzwa kutsauka
A. Kureba:
Simbi mabara anowanzo kuiswa muhurefu hwakatarwa, uye kureba kwekutakura kwakaratidzirwa kunofanirwa kuratidzwa muchibvumirano;
Kusimbisa Mabhasi Anogona kuendeswa muCoils, uye imwe neimwe yeLeel inofanira kunge iri rebar imwe, ichibvumira 5% yehuwandu hwezvikamu mune imwe neimwe batch (maviri zvakare kana isingasviki maviri) inosanganisira maviri ekuzvidza. Iyo diski uremu uye disk dhisiki yakatemwa kuburikidza nekutaurirana pakati pemutengesi uye mutengi.
B. Kureba kutsungirira:
Kutsauka kunogamuchirwa kwehurefu hwesimbi bara parinoiswa kureba hakuzi kukuru kupfuura ± 25m;
Kana urefu hwacho hunodikanwa, kutsauka kwaro + 50mm;
Kana iyo yakakwana urefu inodikanwa, kutsauka kwa -50mm.
C. curvature uye inopera:
Kupera kwebhanhire resimbi kunofanira kunge kwakaratidzwa zvakananga, uye kurongeka kwenzvimbo hakufanire kukanganisa kushandiswa.
