Bearings: osayizi ejwayelekile. osayizi Standard amabombo

Kuyinto ekhethekile eziveza umhlangano okuyinto ingxenye kushaft usekelo asekelayo futhi ukujikeleza noma ukugingqa lona wamuva ngaphandle ngomshikisho ukulahlekelwa amandla. Kunezinhlobo eziningana izingxenye ezifana. Kulokhu, ubukhulu amabombo ezimweni eziningi kulawulwa GOST.

zinhlobo

ISIZINDA yalolu hlobo asetshenziswa umkhakha nezinye imikhakha yezomnotho kukhona kabanzi kakhulu. Kube hydrostatic, igesi-static, amabombo kazibuthe, kanye namanye amaqembu. Nokho, le zilwane ezivamile ifindo ukushelela kanye kweqa. Ngokusho umthwalo beqonda womabili la maqembu zihlukaniswe zibe:

• osabalalayo;

• ukumelana;

• contact emincane.

amabombo ugingqe

Izakhi eziyinhloko zalolu hlobo ISIZINDA kukhona amabhola noma ezinamasondo zitholakala endaweni ibanga elithile kusuka nomunye umnikazi okhethekileyo, obizwa ngokuthi isihlukanisi. Phakathi nalokho kubingelelana, bona Roll zithinte treadmill ngoba amasongo amabili, enye yazo ezimweni eziningi awandi. ISIZINDA zalolu hlobo zisetshenziswa embonini kakhulu. Iqiniso liwukuthi, uma kulinganiswa nokwenu emikhonweni amabombo, banayo eziningi eziwusizo. Ukuze labo zihlanganisa ngomshikisho ngokuyinhloko ongaphakeme futhi kancane igrisi ukusetshenziswa. Ubulula nokufakwa - lena futhi yini umehluko phakathi amabombo ezinjalo. Amazinga (GOST ulawula ubungako bawo) kwamayunithi enjalo okwethulwa amatafula ekhethekile. Ngakho-ke, ukuthola ofanele endabeni ethile, sithwele hhayi ukwenza umzamo omkhulu. Node yalolu hlobo Ungakhetha ngokuphelele yimuphi umklamo hlobo.

Ukuzwela vibration futhi ukushaqeka - the ethile kuphela, okuyinto zingafani amabombo ezinjalo. Amazinga ekukhiqizeni kwabo kumelwe nakanjani ilandelwe. Kungenjalo ngeke kuhlale isikhathi eside kakhulu.

Izinhlobo amabombo ugingqe

Ngaphezu yezingcindezi lolu hlobo ISIZINDA zihlukaniswa ngamaqembu ngokuvumelana nalezi zidingo ezilandelayo:

• Shaped izakhi rolling. Kulesi sici, ukuhlukanisa ibhola kanye roller amabombo. Rolling izakhi ngenkathi uhlobo yokugcina kungenzeka oyindilinga, cylindrical, inaliti emise, ezisontekile, emgqonyeni emise, nokunye. D.

• Ngokwe samoustanovleniya ikhono. Kulokhu, ukuhlukanisa phakathi amabombo eyindilinga futhi nesamoustanavlivayuschiesya.

• Ngokusho enanini lama-elementi ugingqe. Kukhona eyodwa futhi double irowu amabombo.

• Ngobukhulu. Zonke ekhiqizwa samanje ayithintayo le isisekelo zihlukaniswe uchungechunge eziningana.

Kuye chungechunge ku ububanzi efanayo kwangaphakathi, ububanzi eziveza kanye D saso zingahluka. amabombo asetshenzisiwe kukhona ebandleni izimoto, amabhayisikili, imishini ephehlwa umoya nokunye. D.

Ubukhulu

Ubukhulu yalolu hlobo node ichaza GOST 3478-79. Lapho-ke uyaneliswa etholakala amabombo enamandla kakhulu futhi isikhathi eside. Lezi zindinganiso zisebenza kuwo wonke izinhlobonhlobo roller yesifunda, ngaphandle ekhethekile injongo onobuhle, nge design akhethekile. Kulo mBhalo, yezingxenye zingenziwa ezihlukahlukene osayizi, ofanele kakhulu umklamo othize.

Hlola esayizini amabombo uchungechunge ngamunye, njengoba sekushiwo, e amatafula ekhethekile okuyinto ukhombise diameters yangaphandle futhi kwangaphakathi, komncane kunabo wesayizi (Rmin), kanye nobubanzi okuzisholo emasongweni kwangaphakathi futhi yangaphandle (B). Njengoba isibonelo, sikunikeza etafuleni ngochungechunge oluthi nithela diameters 8 (esifushanisiwe).

Okuningi amatafula enemininingwane ingatholakala izincwadi ezikhethekile. Kukhona futhi amazinga e amabombo Compass - umhleli ihluzo, eyenzelwe design abasizwa-computer (design wezincwadi). Kukhona amatafula diameters ezahlukene ISIZINDA.

amakilasi ukunemba

osayizi ejwayelekile kweqa amabombo, ukuze ukwazi ukufunda kusukela kumathebula ekhethekile. Nokho, kwezinye izimo, savumela ngeziphambeko izilinganiso GOST. amabombo ekilasini Ukunemba zihlukaniswe zibe:

• evamile "0";

• "6" lokunemba okusezingeni eliphezulu;

• eliphezulu "5";

• osobovysokoy "4";

• ultra-high "2".

ISIZINDA I-izakhiwo ezahlukene, ungaba tolerances kahle ichazwe. Ngakho, ngokwesibonelo, izindinganiso sihlobene ibhayisikili (608 hlobo) yilezi:

• amabhola ukubekezelelana - 0 / -0.005;

• ithrekhi engaphakathi - + 0.0001 / -0.0003;

• uhlanga yangaphandle - + 0.0001 / -0.0005.

namagama

Rolling amabombo amazinga e ekwakhekeni yabo kuhlangatshezwene nakho saziso. Ukuze ukuthi abathengi ungabona onjani ifindo phambi kwakhe, futhi ngayiphi injongo kungenzeka zisebenzisa ekhethekile wokugubha isicelo. amabombo esiqokiwe ngokuvamile libhalwe setha izinombolo. Ngezinye izikhathi kophawu standard zihlanganisa kokubili izinhlamvu. Kulokhu:

• Inombolo yokuqala noma incwadi ibonisa uhlobo esindayo.

• Letinombolo ezimbili ukucacisa aphethe yochungechunge. Iqembu lokuqala kubonisa ububanzi noma ukuphakama, kwesibili - ububanzi.

• I last Izinombolo ezimbili zimelela ubukhulu ikhodi yokuvula. Uma thina kuphinde by 5, singakwazi ukuthola d ezidlula mm.

osayizi Standard amabombo 66 414 (kulesi simo okutshalwe kuyakhethwa ngokuhambisana GOST 3325-85), isibonelo, njengoba kulandela:

• d - 70 mm;

• D - 180 mm;

• ububanzi - 42 mm;

• isisindo - 5,74 kg.

amabombo plain

Amayunithi yalolu hlobo aqukethe izakhi ezimbili eziyisisekelo: liner sikebhe futhi phakathi okuyizinto zokugcoba ekhethekile. Izinzuzo main yalezi amabombo akhathalela ngokuyinhloko diameters ezincane, kanye nekhono ukubenza futhi ukusebenzisa kushaft detachable kuyinto ipulani eyinkimbinkimbi kakhulu. I nemibi ISIZINDA kwalesi silwane abhekwa hhayi kakhulu ukuphila isikhathi eside futhi isidingo zokugcoba ebizayo.

Izinhlobo slide amabombo

Okwamanje, kukhona ISIZINDA lokhu iqembu:

• ngesivinini;

• Plaka (kusetshenziswa, isibonelo, e crankshafts);

• imishini ukucacisa, eqondisa ngokunembile imiphini futhi kwangenza ukulungiswa igebe;

• ezishibhile izindlela ephansi isivinini;

• okuhlose usebenze ngaphansi kwezimo ezikhethekile (amanzi, ezindaweni onakalisayo).

Kuye mode yokusebenza esindayo yalolu hlobo kungahle ngomshikisho uketshezi noma semifluid. Esimweni sokuqala ebusweni ukusebenza izindlu futhi kushaft zihlukaniswe ungqimba kunalokho obukhulu uwoyela. Lapho ngomshikisho okuxubile sengezwe umngcele okusamanzi (amafutha ngokusebenzisa ifilimu mncane kakhulu kwakhiwa ngezibopho yamangqamuzana).

Ubukhulu ngokuhambisa amabombo

Ubukhulu amasayithi kuleli qembu zinqunywa GOST 2795. Idatha lolutfolakala kumathebula ekhethekile - liphinde yini edingekayo acabangele ngokwenza amabombo ezinjalo. Emacophelo kulokhu kusebenza nemingcele ezifana:

• ububanzi elingaphandle futhi kwangaphakathi;

• ubude (l);

• chamfering ngohlangothi (C);

• tolerances (tolerances).

Ithebula elingezansi (olujiyile) emelelwa amasayizi esezingeni ngokuhambisa amabombo lemigqa ezahlukene.

Izici namathuluzi

Amazinga amabombo plain, Ngakho-ke, akuvunyelwe kuchazwe GOST. Zona ezinye izimfuneko izinga izinto ezisetshenziswa ekukhiqizeni kwabo. Ukunikeza izindlu amaslayidi, njengoba sekushiwo, kungaba wonke noma ukuhlukana. Kulo mBhalo, uxhumano ngokuvamile sisetshenziswa izikhonkwane ezikhethekile noma imishudo. I faka kuyinto eziveza ngokuhambisa kwakhiwa njengoba emkhonweni. Yinye iyunithi ke zingenziwa halves ezimbili. On lapho imiphini, warping, ngokuvamile ukukhwezwa amabombo self-bakubheka.

Izinto ezilandelayo ingasetshenziswa yokukhiqiza lolu hlobo ISIZINDA:

• yensimbi (izindlu);

• nangethusi nensimbi waphonsa noma plastic (i Imigudu).

Kwezinye izimo, kodwa ngokuqinisekile kakhulu ezingavamile, bushings zenziwa ngokhuni, noma ngisho chipboard.

izidingo eziyisisekelo

Ngakho, amazinga amabombo (noma kunalokho, ukuqaliswa yabo) ukuvumela ukukhiqiza izinga esiphezulu, okuhlala isikhathi eside nokuyingozi ukusebenza kakhulu. ISIZINDA eqembu kumele bahlangabezane nalezi zidingo ezilandelayo:

• Izinto kanye nomklamo we amabombo ngokuhambisa kufanele kube ezifana ukunikeza ubuncane ukuhilizisana phakathi kwezindlu kanye emkhonweni.

• Izikhwepha rigidity iyunithi kufanele lube sezingeni elingenza kungaba ukumelana nanoma imaphi ukulayisha oyifunayo.

• Wamukelwa esiphezulu lula eziveza design. Phakathi ukufakwa kungabikho nobunzima.

• Ukuze aveze amabombo ukuze babe ebusweni eyanele sokukhipha ezenzeka ngesikhathi ukusebenza kwendawo ukushisa.

kanjani

Yenza amabombo plain no kweqa ebhizinisini ekhethekile ezinkulu, ngokuvamile ehlanganisa workshop ezimbili eziyinhloko: ezishisayo kanye lokukhanda. Lomhlangano imigqa izitshalo ezifana ngokuvamile usebenza kwimodi okuzenzakalelayo. Ngaphandle kwabo, izitolo nazo efakwe imishini sishaye yesimanje.

Ezweni lethu ezithandwa kakhulu amayunithi eyenziwe abakhiqizi yasekhaya, kanye e-Switzerland (SKF). SKF amabombo ejwayelekile ziyefana ngesiRashiya.
