Chigoba cha mawilo ndiye gawo lalikulu la chigoba, zomwe zimatsimikiza kusinthasintha kwake ndi nthawi yake yogwirira ntchito. Chigobacho chikalephera, chigoba chonsecho chimasiya kugwira ntchito bwino. Pakugwiritsa ntchito tsiku ndi tsiku, "kutopa kwa bearing" ndi chimodzi mwa zolephera zomwe zimachitika kawirikawiri komanso zazikulu. Ndiye, kodi kutentha kwa bearing ndi chiyani? Kodi kumachitika bwanji? Ndipo kodi kungapewedwe bwanji ndikuthetsedwa? Nkhaniyi ikupatsani mayankho atsatanetsatane.
1. Kodi kutopa ndi chogwirira cha caster n'chiyani?
Kutenthedwa ndi ma bearing kumatanthauza vuto lomwe kutentha kosazolowereka panthawi yogwira ntchito kumayambitsa kusintha kwa mtundu, kufewa, kusungunuka, kapena kuwonongeka kwa msewu wothamanga, zinthu zozungulira, kapena khola. Kutenthedwa ndi ma bearing kukakhalapo, bearing kwenikweni imalephera kugwiritsidwa ntchito, ndipo ma casters amataya mphamvu zawo zozungulira, zomwe zimakhudza magwiridwe antchito abwinobwino a zida.
2. Chiyambi cha Mitundu Yodziwika ya Mabearings a Castor
Mitundu yosiyanasiyana ya mabearing a castor ndi yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana. Kumvetsetsa makhalidwe awo kumathandiza kusankha bwino ndikuchepetsa chiopsezo cha kulephera.
1). Maberiyali osalala: Oyenera kugwiritsidwa ntchito pamakina olemera komanso othamanga kwambiri, omwe amagwiritsidwa ntchito kwambiri pazida zolemera zamakanika.
2). Ma roller bearing: Mphamvu yonyamula katundu wambiri, kusinthasintha kozungulira pang'ono, koyenera zochitika zapakati.
3). Derlin Bearing: Yopangidwa ndi pulasitiki yopangidwa ndiukadaulo, yoyenera malo okhala ndi chinyezi kapena zowononga, koma yolimba kwambiri.
4). Maberiyani a mpira: Kuzungulira kosalala komanso kugwira ntchito kokhazikika, koyenera kugwiritsa ntchito komwe kumafuna phokoso lochepa komanso kukhazikika kwakukulu.
5). Maberiyani Okhazikika: Kapangidwe kosavuta, koyenera kuyenda mofulumira komanso mtunda waufupi, komanso kofunikira kukonza pang'ono.
6). Mabeyari ozungulira opindika: Ali ndi mphamvu yonyamula katundu komanso yosinthasintha, yoyenera kugwira ntchito movutikira.
3. Zomwe zimayambitsa kupsa kwa bere
Pali zifukwa zambiri zomwe zingayambitse kupsa kwa mabearings a caster, kuphatikizapo izi:
1). Kudzaza katundu mopitirira muyeso: Kupitirira mphamvu yonyamula katundu yomwe bere limapanga, zomwe zimapangitsa kuti kukangana kukhale kwakukulu.
2). Kusakwanira kutseguka: Kutseguka kwa mkati mwa chivundikirocho sikukwanira, zomwe zimachepetsa kukula ndi kufupika kwa kutentha, ndipo zimatha kupanga kutentha kwambiri mosavuta.
3). Mafuta osayenera: Kusankha molakwika, mafuta ochulukirapo kapena osakwanira kungakhudze momwe kutentha kumatayikira.
4).. Kulondola koyikira: Kulondola kwa makina a shaft kapena bearing housing ndi kochepa, zomwe zimapangitsa kuti bearing igwire ntchito mosakhazikika.
5). Liwiro lalikulu: Kupitirira liwiro lovomerezeka la chogwirira kumabweretsa kutentha kwakukulu.
6). Kupatuka kwakukulu kwa shaft: Shaft imawonongeka kwambiri, zomwe zimapangitsa kuti mphamvu yonyamula zinthu ikhale yosagwirizana komanso kutentha kwambiri m'deralo.
4. Yankho la Kuwotcha kwa Bearing
Pofuna kupewa kupsa kwa ma bearing, tikulimbikitsidwa kuyamba ndi zinthu zotsatirazi:
1). Kusankha mafuta oyenera: Sankhani mafuta oyenera opaka kapena mafuta, ndipo lamulirani kuchuluka kwake kuti muwonetsetse kuti mafutawo apangidwa bwino.
2). Sinthani moyenera malo operekera katundu ndi kuyikapo katundu: pewani kutentha kwambiri komwe kumachitika chifukwa cha malo ochepa kwambiri kapena malo akuluakulu kwambiri operekera katundu.
3). Konzani bwino kapangidwe ka kutseka: letsani kuti zinyalala monga fumbi ndi chinyezi zisalowe mkati mwa bearing ndikukhudza momwe mafuta amakhudzira.
4). Onani kulondola kwa makina a shaft ndi bearing housing: Onetsetsani kuti ma bearing akuyenda bwino komanso ali ndi mphamvu zofanana mukakhazikitsa.
5). Yang'anirani liwiro logwira ntchito: Pewani kugwira ntchito mopitirira muyeso kwa nthawi yayitali ndipo sinthani mtundu wa bearing womwe ndi woyenera kwambiri kugwira ntchito mothamanga kwambiri ngati pakufunika kutero.
5. Mapeto
Thanzi la ma bearing limagwirizana mwachindunji ndi nthawi ya ntchito ya ma caster. Mwa kusankha bwino, kukhazikitsa moyenera, ndi kusamalira nthawi zonse, kuvulala kwa ma bearing ndi zolakwika zina zitha kupewedwa bwino. Ndikukhulupirira kuti nkhaniyi ingakuthandizeni kumvetsetsa bwino kugwiritsa ntchito ndi kukonza ma caster bearing, kukulitsa nthawi ya zida, ndikuchepetsa ndalama zokonzera.
Ngati mukufuna kusintha zina monga makope otsatsa, buku laukadaulo, kapena kanema waufupi, chonde ndidziwitseni ndipo nditha kupitiliza kukonza bwino.
