Chiyambi cha mayendedwe a bulldozer Mapiritsi a bulldozer amatanthawuza zida zamakina olondola zomwe zimagwiritsidwa ntchito popanga ma bulldozer (makina olemetsa omwe amagwiritsidwa ntchito popanga nthaka) kuti athandizire magawo ozungulira, kuchepetsa kugundana, kupirira katundu (radial, axial, kapena kuphatikiza), ndikuwonetsetsa kusinthasintha kolondola kapena kusuntha kozungulira kwa zigawo. Ndizigawo zofunika kwambiri zomwe zimathandiza kuti pakhale ntchito yaikulu ya kutumiza mphamvu za bulldozer, kuyenda, chiwongolero, ndi kachipangizo (fosholo) kagwiridwe kake. Mapangidwe awo ndi kusankha kwawo kumayenderana kwambiri ndi zovuta zazikulu za katundu wolemetsa, kukhudzidwa, kuipitsa, komanso moyo wautali. Kuchokera pamawilo amatope, mpaka ma giya otumizirana matani omwe amapirira mphamvu zambirimbiri, mpaka m'malo olumikizirana matani osinthasintha, mitundu yosiyanasiyana ya ma bere (makamaka ma fani odzigudubuza, zozungulira zozungulira, ndi zolumikizira zolumikizana) zimagwira ntchito zosasinthika m'malo awo. Kumvetsetsa mawonekedwe awo ndi momwe amagwiritsira ntchito ndikofunikira pakupanga, kupanga, kukonza, komanso kuzindikira zolakwika za ma bulldozer. Kusankha -mabere apamwamba, ogwirizana, oikidwa bwino ndi osamalidwa bwino ndi chimodzi mwa zinthu zofunika kwambiri powonetsetsa kuti ma bulldozer akupezeka komanso kugwira ntchito moyenera.
Pali mitundu yosiyanasiyana ya ma bearings omwe amagwiritsidwa ntchito pa bulldozers, ndipo amatha kusankhidwa molingana ndi malo enieni komanso zofunikira zogwirira ntchito.
1. * * Zimbalangondo zodzigudubuza:**
** * Zomwe Zilipo: * * Ikhoza kupirira katundu waukulu wa radial ndi katundu wa axial unidirectional nthawi imodzi, ndi kukhwima kwakukulu komanso kusintha kosavuta kwa chilolezo.
** * Ntchito: * * * Msana wapakati pamayendedwe oyenda * *! Amagwiritsidwa ntchito kwambiri pothandizira ma axle odzigudubuza, mawilo osagwira ntchito, mawilo owongolera, ndi mawilo oyendetsa. Amagwiritsidwanso ntchito kwambiri pamakina otumizira monga ma gearbox, masiyanidwe, ndi ma drive omaliza (sprockets).
2. * * Zozungulira zozungulira: **
** * Zina: * * Yokhala ndi zodzigudubuza za mizere iwiri, imanyamula katundu wozungulira komanso imatha kupirira katundu wina wa bidirectional axial. Ubwino waukulu ndi ntchito yake * * centering * *, yomwe imatha kubweza kusalumikizana bwino pakati pa shaft ndi mpando wonyamula, ndipo imakhala yolimbana ndi kugwedezeka komanso kukhudzidwa.
** * Kugwiritsa ntchito: * * Kawirikawiri amagwiritsidwa ntchito pazigawo zomwe zimanyamula katundu wokulirapo komanso zokhala ndi misalignment pang'ono kapena kugwedezeka pang'ono, monga ma drive sprocket shafts, ma drive ena omaliza, mawilo akuluakulu othandizira, ma idlers, ndi zida zina za * * zogwirira ntchito (mafosholo) * *.
3. * * Mipira yozama yakuya:**
** * Mawonekedwe: * * Amatha kupirira ma radial katundu, komanso amatha kupirira katundu wina wa bidirectional axial, okhala ndi mikangano yotsika, kuthamanga kwambiri, komanso mtengo wotsika mtengo.
** * Kugwiritsa ntchito: * * Amagwiritsidwa ntchito kwambiri m'zigawo zothandizira zomwe zimakhala ndi mphamvu yochepa komanso liwiro lalikulu, monga magudumu owongolera amagetsi, mafani, mapampu amadzi, majenereta, mapampu amadzimadzi/mamotani (non main drive), ndi zina zambiri.
4. * * Mipira yolumikizana ndi ngodya: **
** * Zomwe Zilipo: * * Ikhoza kupirira katundu waukulu wa unidirectional axial, komanso katundu wa radial (nthawi zambiri amachita nthawi imodzi ndi axial katundu).
** * Kugwiritsa ntchito: * * Amagwiritsidwa ntchito makamaka pamene kuwongolera kusuntha kwa axial kapena kunyamula katundu wamkulu wa axial kumafunika, monga kuyika kwa axial kwa ma shaft ena, zowongolerera, ndi mapampu ena a hydraulic mu gearbox.
5. * * Zozungulira zozungulira: **
*Zomwe zilimo: Mofanana ndi ma berelo ozungulira, ili ndi ntchito yodziunikira yokha,-zodzigudubuza, koma zogudubuzazo zimakhala zodzigudubuza, motero mphamvu ya ma radial{1}kunyamula imakhala yokwera kwambiri.
** * Kugwiritsa ntchito: * * Nthawi zina amagwiritsidwa ntchito m'malo mwa zozungulira zozungulira m'malo olemera-antchito omwe amafunikira kulemedwa kwakukulu kwa ma radial ndi kuyanika.
Malo ogwiritsira ntchito
Kunyamula bulldozer ndiye chinsinsi cha njira yotumizira ndikuthandizira makina onse, ndipo imagwiritsidwa ntchito makamaka ku:
Makina oyenda: Magudumu oyendetsa ndi mayendedwe a ma bulldozer omwe amatsatiridwa ayenera kupirira kulemera kwa galimoto yonse ndi mphamvu yakugunda kwapansi 3.
Chipangizo chogwirira ntchito: Kuwongolera kwa bulldozer kukweza ma hydraulic system kumawongolera kusintha kwa ngodya ya tsamba ndi kutumiza katundu.
Dongosolo lamagetsi: Ma fani omwe amalumikizana pakati pa injini ndi gearbox amayenera kuzolowerana ndi ma torque apamwamba komanso malo ogwedera.
Mtengo Wowonjezera Wamakampani
Kuphatikiza pa ma bulldozers, mayendedwe ofanana amagwiritsidwanso ntchito kwambiri mu:
Kupanga mphamvu yamagetsi amadzi: Ma bere apadera a mavavu a pachipata okhala ndi mainchesi opitilira 51cm;
Elevator: ngati gawo lofananira pakukula kwa miyezo yachitetezo chamakampani;
Zida zapadera: Kuponya mivi uta, -makina ogwiritsira ntchito m'nyanja ndi zida zina zoopsa kwambiri zachilengedwe.
Malingaliro osankhidwa ndi kukonza kwa ma bulldozer bearings
Zosankha zosankhidwa
Mtundu wa katundu: Pamene katundu wa axial ndiye katundu wamkulu, zitsulo zoyendetsa zimasankhidwa, ndipo pamene katundu wa radial ndiye katundu wamkulu, zotengera za cylindrical roller zimasankhidwa;
Malo ogwirira ntchito: Ma berelo a zinthu zophatikizika (zosamva +165 digirii ) amakondedwa chifukwa cha kutentha kwambiri, ndipo zitsulo zosapanga dzimbiri zimasankhidwa kuti zizipanga dzimbiri;
Zofananira tsatanetsatane: Onani mphamvu ya bulldozer (monga makina ang'onoang'ono ochepera 37kW ndi makina akulu pamwamba pa 250kW) kuti asankhe mphamvu yofananira yonyamula 6.
Malo osamalira
Yang'anani nthawi zonse kutentha kwapang'onopang'ono (nthawi zambiri Zocheperapo kapena zofanana ndi digiri ya 70) ndi phokoso losazolowereka kuti mupewe kutopa kwakuthupi komwe kumachitika chifukwa chakuchulukirachulukira;
Self lubricating fani sikutanthauza jekeseni mafuta pafupipafupi, koma m'pofunika kupewa zoipitsa kunja kulowa chilolezo 1;
Mukasintha ma bearings, ndikofunikira kuwonetsetsa kuti kusokonezeka kwa makhazikitsidwe kukwanira bwino kuti mupewe kuvala kowonjezera komwe kumachitika chifukwa cha looseness.
