Buku Lothandizira ndi Kukonza Mabearings a Needle Roller

Ubwino ndi kuipa kwa Singano Yodzigudubuza maberiya

Ubwino:

Ubwino wa mabearing a singano: kukana kukangana kochepa, kugwiritsa ntchito mphamvu zochepa, kugwira ntchito bwino kwambiri kwa makina, komanso kuyambitsa kosavuta. Miyeso yake ndi yokhazikika, yosinthika, yosavuta kuyiyika ndikuyichotsa, komanso yosavuta kukonza. Kapangidwe kakang'ono, kulemera kopepuka, komanso miyeso yocheperako ya axial. Kulondola kwambiri, liwiro lozungulira kwambiri, kutopa kochepa komanso moyo wautali wautumiki. Mabearing ena ali ndi magwiridwe antchito odzilungamitsa okha, omwe ndi oyenera kupanga zinthu zambiri. Ali ndi khalidwe lokhazikika komanso lodalirika komanso magwiridwe antchito apamwamba. Mphamvu ya transmission friction ndi yotsika kwambiri kuposa ya mabearing a hydrodynamic, kotero kukwera kwa kutentha kwa friction ndi kugwiritsa ntchito mphamvu ndizochepa. Mphamvu ya friction yoyambira ndi yokwera pang'ono kuposa mphamvu ya friction yozungulira. Kuzindikira kwa kusintha kwa bearing kuti musinthe katundu ndi kochepa kuposa kwa mabearing a hydrodynamic. Imatha kugwira ntchito bwino ndi mafuta ochepa okha ndipo imatha kupereka mafuta kwa nthawi yayitali panthawi yogwira ntchito. Kukula kwa axial ndi kochepa kuposa kwa mabearing achikhalidwe a hydrodynamic. Imatha kupirira nthawi imodzi katundu wophatikizika wa radial ndi thrust. Mkati mwa liwiro lalikulu la katundu, kapangidwe kake kapadera katha kuchita bwino kwambiri. Kagwiridwe ka ntchito ka ma bearing sikokhudza kusinthasintha kwa katundu, liwiro ndi liwiro logwirira ntchito.

Mwachidule, pali mfundo zinayi zokha

1. Kukula kwa ma radial ang'onoang'ono: Ma bearing a singano ali ndi kapangidwe kakang'ono, komwe kangachepetse kwambiri kuchuluka kwa makina akuluakulu ndipo ndi oyenera kugwiritsidwa ntchito komwe kukula kwa ma radial kumafunika kuchepetsedwa.

2. Kupirira katundu wolemera: Mabeyari a singano amatha kupirira katundu wolemera komanso kukhala ndi mphamvu yonyamula katundu wamphamvu, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito molemera komanso mwachangu kwambiri.

3. Kugwira ntchito mosalala: Zinthu zozungulira za mabearing a singano ndi ma cylindrical roller, omwe amakumana ndi malo a raceway a mphete zamkati ndi zakunja, zomwe zimapangitsa kuti ntchito ikhale yosalala komanso yolimba pang'ono. Ndi yoyenera kugwiritsa ntchito mwachangu kwambiri.
4. Mitundu yosiyanasiyana ya ntchito: Mabeya a singano angagwiritsidwe ntchito m'mitundu yosiyanasiyana ya zida zamakanika, monga zida zamagetsi, zida zamaofesi, makina opangidwa ndi nsalu, zida zamankhwala, ndi zina zotero.

Zoyipa:

1. Kukhazikitsa kovuta: Kukhazikitsa ma bearing a singano ndi kovuta kwambiri ndipo kumafuna kugwiritsa ntchito zida zapadera zokhazikitsira. Kukhazikitsa kosayenera kungayambitse kuwonongeka kwa ma bearing.

2. Mtengo wokwera: Mtengo wopanga ma bearing a needle roller ndi wokwera kwambiri, ndipo mitengo yawo ndi yokwera kwambiri, zomwe zimapangitsa kuti asagwiritsidwe ntchito mopanda mtengo.

3. Kukana mphamvu ya axial yochepa: Ma bearing a singano amagwiritsidwa ntchito makamaka kunyamula katundu wa radial. Ali ndi mphamvu ya axial yochepa ndipo sangathe kupirira katundu wochuluka wa axial.

Maberiyani ozungulira singano ali ndi ubwino wa kukula kochepa kwa ma radial, mphamvu yonyamula katundu wambiri, ntchito yosalala komanso kugwiritsa ntchito mosiyanasiyana, komanso ali ndi zovuta za kukhazikitsa kovuta, mtengo wokwera komanso mphamvu yochepa ya axial. Mu ntchito zenizeni, ndikofunikira kusankha mtundu woyenera wa beriyani yozungulira singano kutengera momwe ntchito ikuyendera komanso zofunikira pakugwiritsa ntchito.

Ma taboo khumi a ma Needle Roller bearing

Zinthu khumi zazikulu zomwe sizingagwiritsidwe ntchito ndi mabearing a singano zimakhudza kwambiri maulalo ogwirira ntchito monga kukhazikitsa, kukonza ndi kusungira ‌. Kuphwanya malamulo awa kudzachepetsa kwambiri magwiridwe antchito a mabearing ndikufupikitsa nthawi yawo yogwirira ntchito.

Inezoletsa ntchito zokhazikitsa

Kumenya molunjika thupi la bere: Kumenya mokakamiza kungayambitse kugwa kwa ma singano kapena chidebecho kusokonekera. Manja apadera ayenera kugwiritsidwa ntchito poyika. Ngati pali kusokoneza, njira yoyikira yotentha iyenera kutsatiridwa (kutentha sikuyenera kupitirira 120℃).

Kusakwanira bwino kwa dzenje la shaft: Kutseguka kwambiri kumayambitsa kugwedezeka, ndipo kusokonezeka kwakukulu kumabweretsa kusintha kwa msonkhano. Ndikofunikira kutsatira muyezo woyenerera wa dongosolo la dzenje la shaft/base shaft system.

Kutentha koyikira kutentha sikungatheke: Kutentha kopitirira 120℃ kungayambitse kutenthetsa ndi kufewa kwa chitsulo, kuwononga mphamvu za makina a bearing. Ndikofunikira kugwiritsa ntchito kutentha kwa mafuta osambira ndikukhala ndi chipangizo chowunikira kutentha.

Zoletsa pa ntchito ndi kukonza

Kulephera kwa mafuta kapena kuipitsidwa: Kuuma kwa mafuta ndi kusweka kwa filimu ya mafuta kudzapangitsa kuti mafuta aziwonongeka mofulumira. Mafuta oyera ayenera kusinthidwa nthawi zonse (kusinthidwa sabata iliyonse m'malo opitilira 120℃).

Kusintha kosayenera kwa axial clearance‌ : Mu kapangidwe kamene kali ndi chithandizo chawiri, ngati palibe axial compensation clearance yomwe yasungidwa, imakhala yodzaza kutentha kukasintha.

Kusowa kwa chitetezo chotseka: Kulowa kwa fumbi kumayambitsa mikwingwirima pa msewu wa mpikisano, ndipo chinyezi chochuluka chimayambitsa dzimbiri. Chipangizo chotseka chomwe chili ndi mulingo woteteza wa IP54 kapena kupitirira apo chiyenera kukhala ndi zida.

Kusunga ndi kuletsa zachilengedwe

Kukhudzidwa ndi dzimbiri la mankhwala: Kukhudzana ndi asidi/alkali kudzawononga pamwamba pa chinthu chotsutsana ndi dzimbiri. Malo osungiramo zinthu ayenera kukhala ndi pH yosasunthika komanso chinyezi chosapitirira 65%.

Kusunga kochedwa popanda kukonzedwa: Ngati zinthu zomwe zili m'sitolo zipitirira chaka chimodzi, ziyenera kutsukidwanso kuti zipewe dzimbiri kuti mafuta asawonongeke komanso kuti asidi asawonongeke.

Kusintha kwa kuthamanga kwa ma stacking: Kusintha kwa pulasitiki kwa msewu wothamanga chifukwa cha kuyika ma multilayer kuyenera kutsatiridwa. Njira yosungira yokha ya single layer iyenera kugwiritsidwa ntchito.
