Kubowola chitoliro olowa ndi chigawo chimodzi cha kubowola chitoliro, ogaŵikana olowa mwamuna ndi olowa wamkazi, olumikizidwa pa malekezero onse a kubowola chitoliro thupi. Cholumikizira amaperekedwa ndi ulusi wononga ulusi (wokhuthala ulusi) kulumikiza aliyense chitoliro kubowola. Pobowola, olowa nthawi zambiri disassembled, ndi pamwamba olowa pansi kulumidwa mphamvu ndithu, kotero kubowola chitoliro olowa khoma makulidwe ndi lalikulu, olowa m'mimba mwake ndi lalikulu kuposa chitoliro thupi kunja awiri, ndi aloyi zitsulo. ndi mphamvu zapamwamba zimagwiritsidwa ntchito. Mapaipi obowola pakhomo nthawi zambiri amapangidwa ndi chitsulo cha 35CrMo alloy.
Kulumikizana kwa ulusi wa screw kuyenera kukhutitsidwa ndi zikhalidwe zitatu, ndiko kuti, kukula kwake ndi kofanana, mtundu wa ulusi wopindika ndi womwewo, ndipo ulusi wa screw wamphongo ndi wamkazi umafanana. Miyeso yolumikizana yamitundu yosiyanasiyana ya kubowola ndi yosiyana. Mtundu wa ulusi wa kubowola chitoliro cha kukula kofanana ndi wosiyana. Mtundu wolumikizana womwe umagwiritsidwa ntchito ndi wopanga chitoliro chilichonse chobowola ndizovuta kuti ukhale wokhazikika. Chifukwa chake, kuti tithandizire kusiyanitsa pakati pa zolumikizira mapaipi obowola ndi ntchito zamauinjiniya, API yapanga zofananira pamtundu wa zida zobowola, kupanga ma API olumikizira mapaipi omwe amagwiritsidwa ntchito kwambiri pamakampani amafuta.
Zopangira mapaipi a API zimapezeka mumiyezo yakale komanso yatsopano. Chitoliro chakale cha API kubowola chitoliro chimaperekedwa kuti chigwiritsidwe ntchito koyambirira kwa chitoliro chobowola bwino, chomwe chimagawidwa m'mitundu itatu: mkati mwa lathyathyathya (IF), perforated (FH) ndi wokhazikika (REG).
The mkati lathyathyathya olowa makamaka ntchito kwa kunja thickening wa chitoliro kubowola, amene yodziwika ndi m'mimba mwake wa mkati mobowola chitoliro ndi m'mimba mwake wa mkati olowa pa thickening wa chitoliro thupi, ndi kubowola madzimadzi kutuluka kukana ndi yaing'ono. , zomwe zimathandiza kupititsa patsogolo mphamvu ya madzi a pobowola, koma kunja kwake kwa mgwirizano ndi waukulu komanso wosavuta kuvala.
The perforated olowa ndi oyenera mkati thickening wa kubowola chitoliro, amene yodziwika ndi awiri diamediamets mkati wa kubowola chitoliro, ndi m'mimba mwake mkati mwa olowa ndi wofanana ndi m'mimba mwake wa thickening wa chitoliro thupi, koma zosakwana. m'mimba mwake wa chitoliro thupi gawo. Kukaniza kwamadzimadzi obowola omwe akuyenda pagululi ndikwambiri kuposa gawo lamkati lathyathyathya, koma mainchesi ake akunja ndi ang'onoang'ono kuposa olowa mkati.
Mgwirizano wokhazikika ndi woyenera kukulitsa mkati mwa chitoliro chobowola. The awiri m'mimba mwa olowa ndi ochepa, zosakwana m'mimba mwake wa kubowola chitoliro thickening. Choncho, pali atatu osiyana anabowola diameters wa kubowola chitoliro ogwirizana ndi mfundo yachibadwa. Madzi obowola amayenda kudzera mgululi molimba kwambiri, koma ali ndi m'mimba mwake kakang'ono kwambiri komanso mphamvu yayikulu. Mgwirizano wokhazikika nthawi zambiri umagwiritsidwa ntchito ngati chitoliro chobowola m'mimba mwake ndi chitoliro chobowola m'mbuyo, komanso kubowola, zida zosodza, ndi zina zotere. Mitundu itatu ya mafupa onse amagwiritsa ntchito ulusi wa "V", koma mtundu wa ulusi (wowonetsedwa ndi m'lifupi mwake). top cut), mtunda wa ulusi wowononga, taper ndi kukula kwake ndizosiyana kwambiri.
Chizindikiritso chophatikizana
1.hole FH, XH, osati wamba mu sitolo zida, osati ambiri ntchito.
2.commonly ntchito IF ndi yachibadwa REG, kusiyana ndi motere:
NGATI mabatani 4 pa inchi, ulusi wowononga wachibale ndi wokhuthala, ndipo tepiyo ndi yaying'ono, mabatani a REG 5 pa inchi, ulusi wowononga wachibale ndi wocheperako, ndipo taper ndi yaikulu. Kukula kwa ulusi wa IF screw kumayambira 2-3/8 "mpaka 4-1/2", ndipo zazikulu kuposa 4-1/2 "zilibe IF, nthawi zambiri REG, pomwe 7-5/8" ndi pamwambapa pa REG.
3. Njira yodziwika bwino:
Imayimiridwa ndi manambala atatu, monga 310,410,411, ndi zina.
