Nhanganyaya kune mabulldozer mabearingsBulldozer bearings inoreva chakanyatso mashandiro emuchina anoshandiswa mumabulldozer (muchina unorema weinjiniya unoshandiswa kugadzira pasi) kutsigira zvikamu zvinotenderera, kuderedza kukwenya, kumirisana nemitoro (radial, axial, kana kusanganiswa), uye kuve nechokwadi kutenderera chaiko kana kufamba kwemutsara kwezvikamu. Ndiwo zvinhu zvakakosha zvinogonesa basa guru rekufambisa simba rebulldozer, kufamba, chidhiraivho, uye kushanda kwechishandiso (foshoro) Mabhengi eBulldozer ndizvo zvinhu zvakakosha zvinoona kushanda kwakanaka, kwechokwadi, uye{1}}kunogara kwenguva refu kweiyi "bhemoth yesimbi" munzvimbo dzakaoma zvakanyanya. Dhizaini yavo uye sarudzo inotenderera padhuze nematambudziko makuru emutoro unorema, kukanganisa, kusvibiswa, uye hupenyu hurefu. Kubva pamavhiri erutsigiro ane madhaka, kusvika kumagiya ekutakurisa anoshingirira zviuru zvematani esimba, uye kune anochinjika majoini eblade anochinjika, marudzi akasiyana-siyana emabhengi (kunyanya mabhengi ane tapered, spherical roller bearings, uye majoint bearings) vanotamba zvinzvimbo zvisingadzoreki munzvimbo dzavo. Kunzwisisa maitiro avo uye mashandisiro kwakakosha pakugadzira, kugadzira, kugadzirisa, uye kutadza kuongororwa kwemabulldozer. Kusarudza-mhando yepamusoro, inofambirana, yakaiswa nemazvo uye inochengetedzwa mabhengi ndechimwe chezvinhu zvakakosha pakuona kuti mabulldoza anopinda uye achishanda zvakanaka.
Kune marudzi akasiyana-siyana emabhengi anoshandiswa pamabulldozer, uye anogona kusarudzwa zvichienderana nenzvimbo dzakananga uye zvinoshanda zvinodiwa.

Core application nzvimbo
Kutakura bulldozer ndiyo kiyi yekutapurirana uye tsigiro sisitimu yemuchina wese, uye inoiswa zvakananga kune:
Kufamba meshini: Iyo vhiri rekutyaira uye dhiraivha mavhiri eiyo inotevedzwa bulldozer inoda kumira nehuremu hwemota yese uye pasi friction force ye3.
Chishandiso chinoshanda: Iyo yekusundidzira yebhurudozer inosimudza hydraulic system inodzora kugadziridzwa kwekona yeblade uye kutapurirana mutoro.
Sitimu yemagetsi: Mabheji ari pakubatana pakati peinjini negiya bhokisi anofanirwa kuchinjika kune yakakwira torque uye nharaunda yekudengenyeka.
Indasitiri Yakawedzerwa Kukosha
Pamusoro pemabulldozer, mabhengi akafanana anoshandiswawo zvakanyanya mu:
Hydroelectric power generation: Special bearings for gedhi mavharuvhu ane dhayamita inodarika 51cm;
Elevator yevatyairi: sechikamu chebhenji chekusimudzira kuchengetedzwa kwemaindasitiri;
Midziyo yakakosha: Michina yekupfura miseve, -muchina wekushandisa mugungwa uye zvimwe midziyo yakanyanyisa yezvakatipoteredza.
Mazano ekusarudza uye ekugadzirisa emabhengi e bulldozer
Kusarudza maitiro
Rudzi rwemutoro: Kana axial mutoro uri mutoro mukuru, kutakura kunosarudzwa kunosarudzwa, uye kana radial mutoro uri mutoro mukuru, cylindrical roller bearings inosarudzwa;
Mamiriro ekushanda: Composite material bearings (inopikisa+165 dhigirii) inosarudzwa nokuda kwemamiriro ekushisa kwepamusoro, uye simbi isina tsvina inosarudzwa nokuda kwenzvimbo dzinoparadza;
Tsanangudzo yekuenzanisa: Tarisa kune simba rebulldozer (semichina midiki iri pasi pe37kW uye michina mikuru pamusoro pe250kW) kusarudza inoenderana giredhi resimba rekubereka 6.
Maintenance points
Gara uchitarisa tembiricha yekutakura (kazhinji Zvishoma pane kana zvakaenzana ne70 degree) uye ruzha rusina kujairika kudzivirira kuneta kwezvinhu kunokonzerwa nekuremerwa;
Self lubricating bearings haidi kazhinji jekiseni regirisi, asi zvinodikanwa kudzivirira kunze zvinosvibisa kuti zvisapinde mubearing clearance 1;
Paunenge uchitsiva mabhengi, zvinodikanwa kuve nechokwadi chekumisikidza kupindira kwakakodzera kuti udzivise kuwedzera kupfeka kunokonzerwa nekusununguka.
