Kudzipangira Kokha PrecisionInsert Bearings
Chiyambi cha Zamalonda
● Kutengera njira yolumikizira ndi shaft, mabearing nthawi zambiri amagawidwa m'magulu anayi:
· Setani mtundu wa zomangira
· Mtundu wa kolala yozungulira
· Bore yopindika yokhala ndi chigoba cha adaputala
· Mtundu wa kolala yotseka
● Zipinda zonyamulira katundu zimagawidwa m'magulu malinga ndi zinthu:
· Nyumba zachitsulo zotayidwa
· Nyumba zachitsulo zosindikizidwa
● Maberiyani oikamo zinthu amapangidwa ndi zipangizo zosiyanasiyana zotsekera. Mapangidwe osiyanasiyana otsekera zinthu amatha kusankhidwa kutengera momwe ntchito ikuyendera kuti zitsimikizire kudalirika komanso nthawi yayitali yogwirira ntchito.
Kapangidwe ka Seti ya Mtundu wa Screw Insert Bearing yokhala ndi Pillow Block Housing
● Nyumba Yopangidwa ndi Chitsulo: Kapangidwe kolimba ka monolithic kuti kakhale kosavuta kuyika.
● Mphete Yamkati Yaikulu: Imathandizira kutseka bwino pogwiritsa ntchito zomangira zokhazikika komanso kumawonjezera kulimba.
● Zomangira Zomangira: Zomangira ziwiri zomangira zomwe zimayikidwa pa ngodya za 120° pa mphete yamkati zimaonetsetsa kuti zimamatirira mwamphamvu ku shaft.
● Mphete Zosungira: Chimodzi mbali iliyonse kuti ziletse bwino kulowa kwa fumbi.
● Zomatira za Rubber Zolumikizana: Zimayikidwa mkati mwa mphete zosungira mbali zonse ziwiri kuti zitsimikizire kuti zinthu zozungulira ndi misewu ya mpikisano zimapaka mafuta bwino.
● Kupaka Mafuta: Kumalola kulowetsa mafuta atsopano.
● Malo Ozungulira Odzigwirizanitsa: Amathandizira zokha kusintha kwa shaft kapena kusakhazikika bwino kwa malo oyika.
Kuchotsa Ma Radial
Kutuluka kwa radial kwa ma insert bearing nthawi zambiri kumakhala kwakukulu kuposa kwa ma deep groove ball bearing.
Kodi Mungasankhe Bwanji Ma Bearings?
Kusankha kukula kwa mabearning kumadalira makamaka mphamvu ya katundu, nthawi yogwirira ntchito, komanso kudalirika. Kuchuluka kwa katundu ndi chizindikiro chofunikira kwambiri poyesa mphamvu ya katundu wa mabearning, kuphatikizapo:
● Kuyesa koyambira kwa mphamvu (kwa mikhalidwe yozungulira, n > 10 rpm)
● Kuyeza kwa mphamvu yokhazikika (kwa ntchito zokhazikika, zozungulira pang'onopang'ono, kapena zozungulira, n ≤ 10 rpm)
Monga ma radial ball bearing, ma insert bearing makamaka amapirira mphamvu za radial. Chifukwa chake, kuchuluka kwa katundu wawo kumafotokozedwa motere:
● Ratio yamphamvu yoyendera mphamvu (Cₒ)
● Ratio ya Radial basic static load rating (Cₒᵣ)
Mitengo iyi imaperekedwa m'matebulo a kukula kwa malonda.
Zoganizira za Moyo wa Utumiki
Kuwerengera moyo ndi maziko ofunikira posankha ma bearing ozungulira. "Moyo" nthawi zambiri umatanthauza nthawi yotopetsa. Pakagwiritsidwa ntchito moyenera (kulemera pang'ono, kuyika koyenera, mafuta okwanira), kulephera kwa ma bearing kumachitika makamaka chifukwa cha kutopa kwa malo olumikizirana chifukwa cha kupsinjika kosinthana—chochitika chomwe sichingapewedwe kotheratu.
Komabe, ntchito zosiyanasiyana za makina zimakhala ndi zofunikira zosiyanasiyana. Ma bearing ayenera kukhala ndi magwiridwe antchito enaake mkati mwa nthawi yodziwika. Pambuyo pa ntchito yayitali, phokoso/kugwedezeka kowonjezereka, kutayika kolondola chifukwa cha kuwonongeka, kapena kuwonongeka kwa mafuta kungayambitse kulephera. Nthawi ya moyo yomwe imagawidwa m'magulu malinga ndi momwe zinthu zilili ndi monga:
● Moyo wa phokoso
● Valani moyo
● Moyo wa mafuta odzola
Zolephera zomwe sizikugwirizana ndi nthawi yotopa (monga kugwira, kusweka, ming'alu, kusweka kwa madzi, kulephera kusindikiza) zimaonedwa kuti ndi zolakwika. Izi zimachokera ku kusankha kosayenera, zolakwika pakupanga makina, zolakwika pa kukhazikitsa, kugwiritsa ntchito molakwika, kapena zolakwika pakupanga, ndipo ziyenera kusiyanitsidwa ndi zachilengedwe (nthawi yogwirira ntchito)."
