Ungalinganisa kanjani imvume ye-axial
Lapho ukhetha i-bearing clearance, izici ezilandelayo kufanele zibhekwe:
1. Izimo zokusebenza zokuthwala, njengomthwalo, izinga lokushisa, isivinini, njll.;
2. Izidingo zokuthela ukusebenza (ukunemba kokujikeleza, ithoshi yokungqubuzana, ukudlidliza, umsindo);
3. Lapho i-bearing kanye ne-shaft kanye nomgodi wezindlu kusesimweni sokuphazamiseka, imvume yokuthwala iyancipha;
4. Uma i-bearing isebenza, umehluko wokushisa phakathi kwamasongo angaphakathi nangaphandle uzonciphisa imvume yokuthwala;
5. Ukunciphisa noma ukwandisa imvume yokuthwala ngenxa ye-coefficients yokwandisa ehlukene ye-shaft nezinto zezindlu.
Ngokusho kokuhlangenwe nakho, imvume yokusebenza efanele kakhulu yama-ball bearings iseduze no-zero;ama-roller bearings kufanele agcine inani elincane lemvume yokusebenza.Ezingxenyeni ezidinga ukuqina okuhle kosekelo, ama-FAG bearings avumela inani elithile lokulayisha kuqala.Kuvezwe ngokukhethekile lapha ukuthi lokho okubizwa ngokuthi imvume yokusebenza kubhekisela ekukhishweni kwe-bearing ngaphansi kwezimo zangempela zokusebenza.Kukhona futhi uhlobo lwe-clearance olubizwa ngokuthi yi-original clearance, okubhekisela ekukhishweni ngaphambi kokufakwa kwe-bearing.Imvume yasekuqaleni inkulu kunemvume efakiwe.Ukukhetha kwethu imvume ngokuyinhloko ukukhetha imvume yokusebenza efanele.
Amanani okugunyazwa abekwe ezingeni likazwelonke ahlukaniswe ngamaqembu amathathu: iqembu eliyisisekelo (iqembu 0), iqembu elisizayo elinemvume encane (iqembu 1, 2) kanye neqembu elisizayo elinemvume enkulu (iqembu 3, 4, 5).Lapho ukhetha, ngaphansi kwezimo ezijwayelekile zokusebenza, iqembu eliyisisekelo kufanele likhethwe, ukuze ukuthwala kungathola imvume yokusebenza efanele.Lapho iqembu eliyisisekelo lingakwazi ukuhlangabezana nezidingo zokusetshenziswa, imvume yeqembu elisizayo kufanele ikhethwe.Iqembu elikhulu le-clearance elisizayo lifanele ukuhlangana kokuphazamiseka phakathi kwe-bearing and shaft kanye nomgodi wezindlu.Umehluko wezinga lokushisa phakathi kwamasongo angaphakathi nangaphandle ebheringi mkhulu.I-deep groove ball bearing idinga ukuthwala umthwalo omkhulu we-axial noma idinga ukuthuthukisa ukusebenza kokuziqondanisa.Yehlisa i-torque yokungqubuzana yamabheringi e-NSK nezinye izikhathi;iqembu elisizayo lokususa imvume lifanele izikhathi ezidinga ukunemba okuphezulu kokujikeleza, ukulawula ngokuqinile ukususwa kwe-axial yembobo yezindlu, nokunciphisa ukudlidliza nomsindo.1 Ukulungisa i-bearing
Ngemuva kokunquma uhlobo kanye nemodeli yokuthwala, kuyadingeka ukuklama ngendlela efanele isakhiwo esihlanganisiwe se-rolling bearing ukuze kuqinisekiswe ukusebenza okuvamile kwe-TIMKEN yokuthwala.
Idizayini yesakhiwo esihlanganisiwe ye-bearing ihlanganisa:
1) Shafting ukwesekwa ekupheleni isakhiwo;
2) Ukubambisana kwama-bearings nezingxenye ezihlobene;
3) Ukugcoba kanye nokuvala ama-bearings;
4) Thuthukisa ukuqina kwesistimu yokuthwala
1. Iqiniswe kuzo zombili iziphetho (indlela eyodwa iqiniswe kuzo zombili iziphetho) Kumashafu amafushane (i-span L<400mm) ngaphansi kwezinga lokushisa elivamile lokusebenza, i-fulcrum ivamise ukumiswa ngendlela eyodwa kuzo zombili iziphetho, futhi ibhere ngalinye lithwala amandla e-axial kwelinye. isiqondiso.Njengoba kuboniswe emfanekisweni, ukuze kuvunyelwe inani elincane lokwanda okushisayo kwe-shaft ngesikhathi sokusebenza, ukuthwala kufanele kufakwe nge-axial clearance ye-0.25mm-0.4mm (imvume incane kakhulu, futhi akudingekile ukuba yidwebe emdwebeni wesakhiwo).
Izici: Nciphisa ukunyakaza okukabili kwe-eksisi.Ifanele ama-shafts anoshintsho oluncane lokushisa lokusebenza.Qaphela: Uma ucabangela ukwelula okushisayo, shiya igebe lesinxephezelo c phakathi kwekhava yokuthwala kanye nobuso bangaphandle bangaphandle, c=0.2~0.3mm.2. Uhlangothi olulodwa lugxile kuzo zombili izinhlangothi kanti olunye lubhukuda.Uma i-shaft inde noma izinga lokushisa lokusebenza liphezulu, ukunwetshwa okushisayo nokuncipha kwe-shaft kukhulu.
Isiphetho esinqunyiwe singaphansi kwamandla we-axial we-bidirectional ngeqembu elilodwa eliphethe noma elithwalayo, kuyilapho ukuphela kwamahhala kuqinisekisa ukuthi i-shaft ingakwazi ukubhukuda ngokukhululekile lapho ikhula futhi inkontileka.Ukuze ugweme ukukhulula, indandatho yangaphakathi yesigqoko esintantayo kufanele ilungiswe nge-axially nge-shaft (i-circlip ivame ukusetshenziswa).Izici: I-fulcrum eyodwa igxilile nhlangothi zombili, kanti enye i-fulcrum ihamba nge-axially.I-deep groove ball bearing isetshenziswa njenge-fulcrum entantayo, futhi kukhona igebe phakathi kweringi yangaphandle ye-bearing kanye nesembozo sokugcina.Ama-roller bearings angama-cylindrical asetshenziswa njenge-fulcrum entantayo, futhi indandatho yangaphandle yokuthwala kufanele ilungiswe kuzo zombili izinkomba.
Kuyasebenza: I-eksisi ende enoshintsho olukhulu lokushisa.
