The32217kunyamula ndi wodzigudubuza wamba kwambiri taperedkubereka. Nawa tsatanetsatane wa zambiri zake zazikulu:
1. Mtundu Woyambira ndi Kapangidwe
- Mtundu: Tapered roller yonyamula. Mtundu woterewu umapangidwa kuti uzitha kupirira ma radial katundu (makamaka perpendicular to shaft) ndi katundu wamkulu wa unidirectional axial (mphamvu motsatira njira ya shaft).
- Kapangidwe kake: Ili ndi zigawo zinayi zazikulu:
- Mphete yamkati: Koloni yokhala ndi msewu wothamanga, wokwera pamtengo.
- Mphete yakunja: Kapu yokhala ndi msewu wothamanga, woyikidwa m'nyumba yonyamula.
- Zodzigudubuza zopindika: Zinthu zozungulira ngati Frustum zomwe zimazungulira pakati pa mipikisano yamkati ndi kunja kwa mphete. Odzigudubuza nthawi zambiri amatsogoleredwa bwino ndikulekanitsidwa ndi khola.
- Khola: Nthawi zambiri amapangidwa ndi chitsulo chosindikizidwa, mkuwa wotembenuzidwa, kapena mapulasitiki aumisiri, amagwiritsidwa ntchito kulekanitsa ma rollers ndikuchepetsa mikangano ndi kuvala.
2. Kutanthauzira Kwachitsanzo (Muyezo wa ISO)
-32217:
- 3 : Imayimira chotengera chodzigudubuza.
- 22 : Imayimira mndandanda wamagawo. Makamaka:
- M'lifupi mndandanda: 2 (wapakati m'lifupi)
- M'mimba mwake: 2 (m'mimba mwake)
- 17 : Imayimira khodi ya bore diameter. Kwa ma bere okhala ndi m'mimba mwake≥20mm, m'mimba mwake = 17× 5 = 85 mm.
3. Miyeso Yaikulu (Makhalidwe Okhazikika)
- M'mimba mwake (d): 85 mm
- M'mimba mwake (D): 150 mm
- M'lifupi / kutalika (T / B / C): 39 mm (Izi ndizomwe zili m'lifupi / kutalika kwa chonyamulira, mwachitsanzo, mtunda kuchokera kumbali yaikulu ya mapeto a mphete yamkati mpaka kumapeto kwakukulu kwa mphete yakunja. Nthawi zina mphete yamkati B ndi m'lifupi mwake C imatchulidwanso, koma T ndizomwe zimagwiritsidwa ntchito kwambiri m'lifupi).
- M'lifupi mphete yamkati (B): Pafupifupi 39 mm (nthawi zambiri amafanana kapena pafupi ndi T; onetsani tebulo la miyeso kuti mumve zambiri).
- M'lifupi mphete yakunja (C): Pafupifupi 32 mm (onani tsatanetsatane wa tebulo la miyeso).
- mphete yamkati ya nthiti yaying'ono (d₁ ≈): Pafupifupi 104.5 mm (kuwerengera unsembe).
- mphete yakunja yaing'ono ya nthiti (D₁ ≈): Pafupifupi 130 mm (kuwerengera unsembe).
- Contact angle (α): Nthawi zambiri pakati pa 10° ndi 18°, mtengo weniweniwo uyenera kufufuzidwa mu kalozera wa opanga zonyamula. Njira yolumikizirana imatsimikizira mphamvu yonyamula katundu wa axial.
- Fillet radius (r min): Nthawi zambiri, utali wocheperako wa mphete zamkati ndi zakunja ndi 2.1 mm (panthawi yoyika, chidwi chiyenera kulipidwa kuti fillet ya shaft phewa ndi mapewa onyamula mapewa asakhale ochepa kuposa mtengo uwu).
4. Makhalidwe Amagwiridwe Aakulu
- Kutha kunyamula katundu wambiri: Kulimba kwambiri polimbana ndi katundu wa axial unidirectional, komanso kumatha kunyamula katundu wokulirapo. Odzigudubuza amalumikizana pamzere wothamanga, zomwe zimapangitsa kugawa bwino katundu.
- Kupatukana: Msonkhano wa mphete wamkati (mphete yamkati + odzigudubuza + khola) ndi mphete yakunja ikhoza kukhazikitsidwa paokha, yomwe ili yabwino kwambiri kuyika, kusintha, ndi kukonza.
- Kufunika kogwiritsa ntchito pawiri: Popeza imatha kunyamula katundu wa axial unidirectional, nthawi zomwe bidirectional axial loads imayenera kunyamulidwa kapena kuyika bwino kwa shaft kumafunika (monga shafting), kunyamula kwa 32217 nthawi zambiri kumayenera kugwiritsidwa ntchito awiriawiri (kumaso ndi maso, kusinthana ndikusintha, kusinthana ndikusintha, kusintha ndikusintha). kutsitsa.
- Chilolezo chosinthika: Posintha malo achibale a axial pakati pa mphete zamkati ndi zakunja, chilolezo chamkati cha kunyamula kapena kulowetsamo chikhoza kusinthidwa mosavuta kuti chipeze kukhazikika kwabwino, kulondola kozungulira, ndi moyo wautumiki.
- Liwiro lozungulira: Liwiro lochepetsera nthawi zambiri limakhala lotsika kuposa la mayendedwe a mpira wakuya, koma limatha kukwaniritsa zosowa zamafakitale ambiri. Kuthamanga kwapadera kumadalira njira yothira mafuta, katundu, mtundu wa khola, ndi zina zotero.
- Kukangana ndi kukwera kwa kutentha: Kukangana kokwanira kumakhala kokwera pang'ono kuposa kwa mayendedwe a mpira, ndipo kukwera kwa kutentha panthawi yogwira ntchito kungakhale kokwera pang'ono.
5. Kusamala Kuyika
- Kugwiritsa ntchito pawiri: Monga tanena kale, nthawi zambiri imayikidwa pawiri.
- Sinthani chilolezo / preload: Pambuyo kukhazikitsa, malo axial ayenera kusinthidwa mosamala kuti akwaniritse chilolezo chopangidwa kapena kutsitsa. Izi ndizofunikira kwambiri kuti zigwire ntchito komanso moyo wautumiki.
- Shaft phewa ndi nyumba yonyamula mapewa: Ndikofunikira kuwonetsetsa kuti kutalika kwa phewa la shaft ndi nyumba yonyamula mapewa ndikokwanira kuthandizira mphete yonyamula, koma osati yokwera kwambiri kuti ingalepheretse kuyika kapena kusokoneza utali wa fillet. Miyeso ya mapewa iyenera kupangidwa mosamalitsa malinga ndi malingaliro omwe ali mu kabukhu lonyamula.
- Kupaka mafuta: Kupaka mafuta okwanira komanso koyenera (kupaka mafuta kapena kuthira mafuta) kuyenera kuperekedwa, chifukwa kuthirira kumakhudza kwambiri moyo wantchito.
6. Common Application Fields
Mapiritsi odzigudubuza amagwiritsidwa ntchito kwambiri pazochitika zomwe zimafunika kunyamula katundu wa radial ndi axial, makamaka pamene katundu wa axial ndi wamkulu:
- Ma gearbox (magalimoto otumiza, zochepetsera mafakitale)
- Ma axles agalimoto (ma wheel hubs, zosiyana)
- Pereka makosi a mphero zogudubuza
- Makina opangira migodi
- Makina omanga
- Makina aulimi
- Pampu
- Cranes
- Zida zina zamakina zida spindles
