Mawonekedwe a Double Row Angular Contact Ball Bearings
- Kuchuluka Kwambiri:Mizere iwiri ya mipira imachulukitsa kwambiri ma radial ndi axial (makamaka bi-directional axial) mphamvu yonyamula katundu.
- Kukhazikika Kwambiri:Mapangidwe a mizere iwiri amapereka kukhazikika kwapamwamba ndi kukhazikika pansi pa mphindi zogubuduza kapena katundu wophatikizidwa, kupereka kukana kwakukulu kwa deformation.
- Bi-Directional Axial Load Support:Uwu ndiye mwayi wodziwika bwino wa mizere iwiri yamakona olumikizana ndi mpira. Chonyamula chimodzi chikhoza kuthandizira katundu wa axial kuchokera mbali zonse ziwiri (mwachitsanzo, kumanzere ndi kumanja) pokhalabe olondola kwambiri komanso osasunthika. Palibe chifukwa chophatikiza mizere iwiri kuti mukwaniritse chithandizo cha mbali ziwiri.
- Kulondola Kwambiri Kuthamanga:Amapangidwa molunjika kwambiri, kuwonetsetsa kuti akuyenda bwino komanso mozungulira.
- Kukhazikika:Ngakhale ali ndi mizere iwiri ya mipira, mapangidwe ake nthawi zambiri amakhala ophatikizika kuposa kugwiritsa ntchito kuphatikiza kwa mizere iwiri yolowera kumbuyo ndi kumbuyo kapena yakumaso ndi maso, mizere imodzi, kupulumutsa malo okwera.
- Kuyika Kosavuta:Monga gawo lophatikizika, kuyika kumakhala kosavuta kuposa mizere yolumikizana ndi mizere imodzi ndikuwonetsetsa kuti muloledwe kapena kuyikatu.
- Kusintha Koyamba:Mizere yambiri yolumikizana ndi mizere iwiri imaperekedwa ndi zowongolera bwino (zopepuka kapena zapakati) kuti muzitha kukhazikika bwino, kuthamanga bwino, komanso moyo wantchito.
Gulu la Double Row Angular Contact Ball Bearings
- Mizere iwiri yolumikizana ndi mipiringidzo yamakona amasankhidwa potengera momwe amalumikizirana komanso mawonekedwe ake:
- Ndi Contact angle:
- 15 ° Njira Yolumikizirana:Kugogomezera kuthekera kothamanga kwambiri; oyenerera katundu wa axial wapakati koma zofunikira zothamanga kwambiri.
- 25 ° Contact Angle (Yodziwika Kwambiri):Amapereka kuphatikiza koyenera kwa ma radial / axial katundu, kulimba, ndi liwiro; mtundu wogwiritsidwa ntchito kwambiri.
- 30°/40° Contact angle:Imayang'ana kwambiri mphamvu ya axial katundu ndi kukhazikika; oyenera katundu makamaka axial pa liwiro lotsika.
- Mwa Mapangidwe Kapangidwe:
- Mtundu Wokhazikika:Mphete zakunja zolimba komanso mphete zamkati zolekanitsidwa (nthawi zambiri zimakhala ndi ma flanges kapena nthiti). Mapangidwe ambiri (mwachitsanzo, 3300, 3200 mndandanda).
- Mtundu Wosindikizidwa/Wotetezedwa:Zokhala ndi zisindikizo za rabara (RS/2RS) kapena zishango zosalumikizana (ZZ/2Z) zokhala ndi malo omwe amafunikira chitetezo ku fumbi, chinyezi, kapena kusunga mafuta.
- Flanged Outer mphete:Mphete yakunja imakhala ndi flange yoyika mosavuta axial ndikuyika kosavuta.
- Tapered Bore:Mphete yamkati ili ndi chobowola chotchinga kuti chiloledwe / kusinthiratu kusinthidwa ndi axial kusamuka.
- Katundu Wapamwamba/Mapangidwe Apadera:Monga mphete zogawanitsa zamkati kapena zakunja (mwachitsanzo, mapangidwe amtundu wa 3200), zokongoletsedwa kuti zigawidwe kupsinjika kuti zipititse patsogolo kuchuluka kwa axial katundu.
- Ndi Size Series:Zosankhidwa molingana ndi miyezo ya ISO dimension Series (mwachitsanzo, 32, 33 mndandanda), zomwe zikuwonetsa m'lifupi mwake mpaka m'mimba mwake.

Kugwiritsa Ntchito Double Row Angular Contact Ball Bearings
Pogwiritsa ntchito kusasunthika kwawo, kulondola, komanso kukwanitsa kukankhira pawiri, mizere iwiri yolumikizana ndi mipiringidzo ya angular imagwiritsidwa ntchito kwambiri pamapulogalamu omwe amafunikira kuthandizira katundu wophatikizana (makamaka mphamvu za bidirectional axial ndi mphindi zogubuduza) komanso kufuna kulondola kozungulira kwambiri. Zitsanzo ndi izi:
- Zida Zopangira Makina:Zinyalala za spindles mu lathes, makina mphero, makina akupera, etc., kumene iwo ali mmodzi wa ambiri ntchito.
- Ma gearbox:Kuthandizira ma shafts otulutsa muzitsulo zochepetsera ma pulaneti ndi ma gearbox a mafakitale (nthawi zambiri zimafuna kuti axial thrust ndi kuthandizira mphindi yopendekera).
- Pampu Zamakampani:Thandizo la shaft mu mapampu apakati, mapampu owononga, ndi zina zotero, kunyamula katundu wa radial ndi bidirectional axial.
- Makina omanga/zaulimi:Sungani ma shafts, mphete zopha.
- Makina Osindikizira:Zonyamula za Cylinder, zomwe zimafuna kulondola kwambiri komanso kugwira ntchito bwino.
- Makina a Pulasitiki & Labala:Thandizo la screw mu extruder, mayendedwe ozungulira mu ma calender / osakaniza.
- Mafani/Mawomba:Thandizo la rotor mu mafani othamanga kwambiri.
- Zagalimoto:Mapulogalamu ocheperako omwe amagwira ntchito kwambiri (mwachitsanzo, ma bearings otulutsa ma clutch apamwamba), koma ocheperako poyerekeza ndi mzere umodzi kapena ma point-point-contact ma bere chifukwa chazovuta za danga.
- Zolumikizana za Robot.
Zindikirani: Timapereka mizere yambiri yolumikizana ndi mizere iwiri. Chonde titumizireni kuti musankhe momwe mungagwirire bwino ndi zomwe mukufuna kugwiritsa ntchito (kukula kwa katundu & mayendedwe, liwiro, zolondola, malo okwera, momwe chilengedwe, ndi zina).
