Sesibe kule mboni isikhathi eside, ukubekezelela ukulingana phakathi kwe-bearing and shaft, kanye nokubekezelela ukulingana phakathi kwe-bearing and hole, bekulokhu kukwazi ukufeza umsebenzi ngokulingana okuncane, futhi kungukuthi. kulula ukuhlanganisa nokuhlakaza. Kodwa-ke, ezinye izingxenye zisadinga ukuba nokunemba okuthile okufanayo.
I-Fit tolerance iyisamba sembobo kanye nokubekezelelana kwe-shaft okwenza ukulingana. Inani lokuhlukahluka elivumela imvume ukuthi iphazamise.
Ubukhulu bendawo yokubekezelelana kanye nesimo sendawo yokubekezelela umgodi kanye ne-shaft yenza ukubekezelelana okufanelekile. Ubukhulu bembobo kanye nokubekezelelana kokufaneleka kwe-shaft kubonisa ukunemba okufanelekile kwembobo kanye ne-shaft. Usayizi nendawo yembobo ne-shaft fit tolerance zone kukhombisa ukunemba kokufaneleka kanye nemvelo yokulingana yembobo kanye ne-shaft.
01 Ukukhethwa kwekilasi lokubekezelelana
Isigaba sokubekezelela se-shaft noma ibhore yezindlu esilingana ne-bearing sihlobene nokunemba kokuthwala. Ku-shaft ehambisana nokunemba kwebanga le-P0, izinga lokubekezelela ngokuvamile liyi-IT6, futhi imbobo yesihlalo esinesihlalo ngokuvamile i-IT7. Ezikhathini ezinezidingo eziphezulu zokunemba kokujikeleza nokuzinza kokugijima (njengamamotho, njll.), i-shaft kufanele ikhethwe njenge-IT5, futhi imbobo yesihlalo esinesihlalo kufanele ibe yi-IT6.
02 Ukukhethwa kwendawo yokubekezelelana
Umthwalo we-radial olinganayo uhlukaniswe ngemithwalo "elula", "evamile" kanye "nesindayo". Ubudlelwano phakathi kwayo nomthwalo oguquguqukayo olinganiselwe ongu-C wokuthwala yilokhu: umthwalo omncane P≤0.06C umthwalo ojwayelekile 0.06C
(1) Indawo yokubekezelela umphini
Ukuze uthole indawo yokubekezelela ye-shaft lapho ukuthwala kwe-radial kanye ne-angular contact bear kufakwe khona, bheka ithebula lendawo yokubekezelelana elihambisanayo. Ezikhathini eziningi, i-shaft iyazungeza futhi isiqondiso somthwalo we-radial asishintshi, okungukuthi, lapho iringi yangaphakathi ethwele izungeza ngokuhlobene nesiqondiso somthwalo, ukulingana koshintsho noma ukuphazamiseka kufanele ngokuvamile kukhethwe. Lapho i-shaft imile futhi isiqondiso somthwalo we-radial singashintshiwe, okungukuthi, lapho indandatho yangaphakathi ye-bearing imile ngokuhambisana nesiqondiso somthwalo, ukuguqulwa noma ukulingana okuncane kwemvume kungakhethwa (imvume eningi kakhulu ayivunyelwe).
(2) Indawo yokubekezelela imbobo yegobolondo
Ukuze uthole indawo yokubekezelela indawo yokubekezelela izindlu kuma-radial kanye nama-angular contact bearings, bheka ithebula lendawo yokubekezelela elihambisanayo. Lapho ukhetha, qaphela ukuze ugweme ukuvunyelwa kokulingana kwamasongo angaphandle azungezayo noma azungezisayo lapho ukulayisha khona. Usayizi womthwalo we-radial olinganayo uphinde uthinte ukukhethwa kokulingana kweringi yangaphandle.
(3) Ukukhethwa kwesakhiwo sezindlu ezithwele
Ngaphandle-ke uma kunesidingo esikhethekile, isihlalo esinesihlalo esiginqikayo sithatha isakhiwo esibalulekile. Isihlalo sokuhlukanisa sisetshenziswa kuphela lapho umhlangano unzima, noma inzuzo yokuhlangana elula ukucatshangelwa okuyinhloko, kodwa ayikwazi ukusetshenziselwa ukulingana okuqinile. Noma ukulingana okunembe kakhudlwana, okufana ne-K7 nokulingana okuqinile kune-K7, noma imbobo yesihlalo enesigaba sokubekezelelana se-IT6 noma ngaphezulu, ngeke kusebenzise indlu ehlukanisiwe.
