Open Mtundu Deep Groove Ball Bearings

Kuwonjezera pa ma bearing otseguka, ma bearing otsekedwa amapezekanso kuti agwiritsidwe ntchito pamene kubwezeretsanso mafuta kumakhala kovuta. Mitundu yake ndi iyi:

· Maberiya okhala ndi chishango chimodzi kapena ziwiri (zotchedwa Z, 2Z).

· Maberiya okhala ndi zisindikizo chimodzi kapena ziwiri zosakhudzana (zotchedwa RZ, 2RZ).

· Mabearing okhala ndi zisindikizo chimodzi kapena ziwiri zolumikizirana (zotchedwa RS1, 2RS1).

Maberiyani awa ndi oyenera kugwiritsidwa ntchito mwachangu kwambiri. Amapaka mafuta okwanira panthawi yopanga ndipo safuna kutsukidwa kapena kuwonjezeredwa mafuta panthawi yoyika. Mafutawa amathandiza kupewa dzimbiri komanso kutseka. Maberiyani awa amagwiritsidwa ntchito kwambiri m'makina osiyanasiyana, makamaka m'malo ovuta kumene kutseka komangidwa mkati kumafunika. Kuchuluka kwa mafuta odzaza kumadalira kukula kwa beriyani ndi momwe imagwirira ntchito, nthawi zambiri kumakhala 25% mpaka 35% ya malo omasuka mkati.

Ma bearing a mpira wozama wokhala ndi ma snap ring grooves kapena ma snap ring ring pa mphete yakunja alipo. Ma bearing awa amathandiza kuti kapangidwe ka nyumba kakhale kosavuta polola bearing kukhala yolimba m'nyumba pogwiritsa ntchito snap ring. Amakondedwa pamene malo oyikapo ali ochepa. Miyeso yofanana ya snap ring yalembedwa m'matebulo a miyeso ya bearing.

Ma bearing opanda phokoso lochepa alipo, monga:

· Ma bearing a phokoso lochepa omwe ali ndi ma code owonjezera Z1, Z2, Z3.

· Ma bearing a phokoso lotsika kwambiri okhala ndi code yomaliza Z4, yoyenera kugwiritsidwa ntchito mwakachetechete m'magwiritsidwe ntchito monga ma air conditioner motors.

· Ma bearing a phokoso lotsika la liwiro okhala ndi ma code a suffix V1, V2, V3.

Mitundu yosiyanasiyana ya ma bearing a mpira wozama kwambiri ikhoza kusinthidwa malinga ndi zosowa za ogwiritsa ntchito. Ma bearing amapezeka m'magulu osiyanasiyana olekerera komanso magulu ogwedezeka.

Miyeso ya mitundu yoyambira ya ma bearing yomwe yatchulidwa mu matebulo a miyeso ikugwirizana ndi ISO 15:1981. Miyeso ya ma snap ring grooves ndi ma snap rings ikugwirizana ndi ISO 464:1976.

Ma bearing a mpira wa mzere umodzi ali ndi mphamvu zochepa zololeza kusagwirizana kwa angular. Kusagwirizana kwakukulu kololedwa pakati pa mphete zamkati ndi zakunja kumadalira mtunda wolowera, kukula kwa bearing, kapangidwe ka mkati, ndi mphamvu ndi nthawi zomwe zimagwira ntchito pa bearing. Kusagwirizana kwakukulu kololedwa kuyenera kuonetsetsa kuti palibe kupsinjika kowonjezereka komwe kumachitika mkati mwa bearing. Chifukwa cha ubale wovuta pakati pa zinthu izi, mtengo weniweni wa kusagwirizana kwakukulu kololedwa kwa angular ndi wovuta kufotokoza. Komabe, pansi pa mikhalidwe yabwinobwino yogwirira ntchito, ndi pafupifupi mphindi 2 mpaka 10.

Tiyenera kudziwa kuti kusagwirizana kwa angular pakati pa mphete zamkati ndi zakunja panthawi yogwira ntchito kudzawonjezera phokoso kwambiri. Ma bearing a mpira okhala ndi mizere iwiri amatha kungolola kusagwirizana kwa angular kwa mphindi ziwiri zokha. Kusagwirizana kwakukulu kudzawonjezera katundu pa mipira ndi misewu ya raceways, zomwe zingachepetse moyo wa ntchito ya bearing.

Ma bearing a mpira wozama kwambiri amapangidwa malinga ndi kalasi ya P0 tolerance. Ma bearing olondola kwambiri, monga P6, P5, P4, ndi P2, amapezekanso.

Ma bearing a mpira wozama kwambiri amaperekedwa ndi chilolezo cha gulu la C0. Ma bearing omwe ali ndi mipata yayikulu kapena yaying'ono kuposa gulu lokhazikika amapezekanso. Ma bearing a mpira wozama kwambiri okhala ndi mizere iwiri ali ndi chilolezo chamkati cha radial.

Maberiya olumikizana kumbuyo kapena maso ndi maso nthawi zambiri amapezeka m'makonzedwe awiri otsatirawa:

· Malo ang'onoang'ono ozungulira (code yomaliza CA).

· Kuyika pang'ono pasadakhale (chiphaso khodi GA).

Izi zikupezeka mu mndandanda wa 60, 62, ndi 63.

Miyezo yovomerezeka ndi yoyambira ya ma bearing ophatikizidwa yaperekedwa mu tebulo ili m'munsimu:
