Ama-bulldozer bearings ayizinsimbi eziwumgogodla ezisetshenziselwa ukusekela izingxenye ezijikelezayo, ukunciphisa ukungqubuzana, nokudlulisa imithwalo. Ngokuvamile ahlanganisa iringi yangaphakathi (ukukhwelana ne-shaft), iringi yangaphandle (ukukhwelana nendlu), izakhi ezigoqayo (amabhola ensimbi, amarola, njll.), kanye nekheji (ehlukanisa izinto ezigoqayo). Impahla yayo ikakhulukazi insimbi enekhabhoni chromium ephezulu (efana ne-GCr15), enokuqina okuphezulu (ukuqina kwento egoqayo kufinyelela ku-HRC60-65), ukumelana nokugqoka, nokumelana nokukhathala ngemuva kokwelashwa kokushisa. Ingakwazi ukuzivumelanisa nezimo ezinzima zokusebenza zama-bulldozers njengomthwalo osindayo, ukudlidliza, uthuli, njll.Ngokohlobo lwe-friction, ama-bulldozer bearings angahlukaniswa abe ama-rolling bearings (okunciphisa ukungqubuzana ngokusebenzisa izakhi ezigoqayo futhi asetshenziswa kakhulu) kanye nama-sliding bearings (okusekelwa ukungqubuzana kwe-sliding). Phakathi kwazo, ama-rolling bearings abe yizici ezithandwayo ezijikelezayo zama-bulldozer ngenxa ye-coefficient yabo ephansi yokungqubuzana nokuguquguquka kwesivinini esinamandla.1. Ukusekela izingxenye ezijikelezayoNikeza ukuma kwe-radial kanye ne-axial yezingxenye ze-shaft (njengama-shaft shaft, ama-giya shaft) ukuze kuqinisekiswe ukusebenza okuzinzile kwezingxenye ezijikelezayo (amagiya, ama-sprocket, njll.) emigwaqweni enqunywe kusengaphambili, ukugwema ukudlidliza noma ukungqubuzana okubangelwa ukuguquguquka.Yehlisa ukulahlekelwa kokungqubuzana2. Guqula ukuslayida kwezingxenye ezijikelezayo kube ukungqubuzana (noma ukuslayida okuphansi) ngokusebenzisa izakhi eziginqikayo (noma izindawo ezishelelayo), nciphisa ukulahleka kwamandla ngesikhathi sokudluliswa kwamandla, futhi uthuthukise ukusebenza kahle kokudlulisela.Ukuthwala nokudlulisa imithwalo3. Thatha umthwalo we-radial (njengesisindo somuntu siqu se-shaft, amandla e-radial we-gear meshing) kanye nomthwalo we-axial (njengamandla e-axial akhiqizwa ukuphonswa kwefosholo likagandaganda) ngesikhathi sokusebenza kwegandaganda, futhi udlulisele umthwalo egobolondweni noma kuhlaka ukuze ugweme ukuguga okuqondile komzimba we-shaft ngaphansi kokuphoqelelwa.
Izimo zohlelo lokusebenza ezijwayelekile
Uma ogandaganda besebenza (njengokusunduza inhlabathi eqinile noma ukugibela imithambeka), ama-bearings adinga ukumelana nemithwalo emikhulu (njengomthwalo osheshayo wamabheringi esondo lokushayela ofinyelela amathani angaphezu kuka-10), ngakho-ke kuyadingeka ukukhetha ama-bearing anama-coefficients anama-coefficient aphezulu (njengama-roller ama-tapered nama-roller ajiyileyo kanye nokujiya kwawo{1}} kanye nokuqinisa i-roller material.
2. Anti ukungcola kanye nokubeka uphawu
Indawo yokusebenza inothuli futhi inodaka, futhi ama-bearings adinga ukusetshenziswa ngokuhambisana nezingxenye zokuvala (njengezivalo zikawoyela nezimbozo zothuli):
Izingxenye eziveziwe (ezinjengama-track drive wheel bearings) zidinga izigxivizo zamafutha ezindebe eziphindwe kabili kanye nesembozo sothuli ukuze kuvinjelwe udaka nesihlabathi ekungeneni komjaho (ukungcola kungabangela "ukuguga okubi" kwama-bearings, kunciphise isikhathi sazo sokuphila ngaphezu kuka-50%);
Ama-bearings angaphakathi ku-gearbox ancike ekugcotshweni kukawoyela wegiya nasekuvalekeni, futhi kuyadingeka ukuqinisekisa ukuthi u-gearbox awuvuzi.
3. Ukugcotshwa nokuchithwa kokushisa
Ama-bearings ajikelezayo ngesivinini esiphezulu (njengama-spindle bearings e-gearbox) adinga ukugcotshwa okuphoqelelwe ngamafutha egiya (ajovwe ngamashaneli kawoyela) ukuze kususwe ukushisa okungqubuzanayo (ukugwema ukwehluleka kwamafutha okubangelwa amazinga okushisa aphezulu);
Ama-duty bearings anesivinini esiphansi-esindayo (njengama-bucket pin roller bearings) adinga ukugcotshwa njalo ngamafutha (kanye ngemva kwamahora angu-200) ukuze enze ifilimu kawoyela futhi kuncishiswe ukungqubuzana.
·Inkinga: Ukwehluleka kwangaphambi kwesikhathi kwamabheringi amasondo okusekela okubangelwa umthelela wedwala. Isixazululo:
Ukwamukela imigqa emithathu yama-roller ama-tapered (okukhuphuka ngo-50% komthwalo{1}}umthamo wokuthwala)
Ukuthuthukiswa kwe-Roller Logarithmic Curve (Ukufaniswa Kokusabalalisa Kwengcindezi)
Upgrade lubricating grease to fully synthetic lithium based grease (drip point>260 degree)
2. Indawo yokwakhiwa kwexhaphozi:
·Inselelo: Ukwehluleka kokuvala okubangelwa ukungena kwamanzi/kwenhlabathi · Idizayini eqanjiwe:
I-Double lip oil seal+magnetic fluid seal (isilinganiso sokungangeni manzi kwe-IP68)
Engeza iziteshi zokudonsa amanzi esihlalweni esinezintambo (njenge-Caterpillar D6T design)
3. Ukusebenza-ezifundeni eziphakeme:
·Iphuzu lobuhlungu: Izinga lokushisa eliphansi elingu -50℃C libangela ukuba amafutha aqine. Isinyathelo sokuphikisa:
Amafutha agcwele izinga lokushisa aphansi-aphansi ngaphambili kumabheringi (asengageleza ku -60℃C)
Khetha insimbi enokuqina okuphezulu (Amandla omthelela we-Charpy Amakhulu noma alingana no-100J)
