Sisebenzisa ubuncinane iibheringi ezingama-200 yonke imihla ebomini bethu. Ibutshintshile ubomi bethu. Ngoku izazinzulu zikwanika iibheringi ngengqondo elumkileyo, ukuze ikwazi ukucinga nokuthetha. Ngale ndlela, ngenxa yeebheringi ezichanekileyo kwi-high-speed rail, abantu banokuqonda zonke iimeko zeebheringi ngaphandle kokugcinwa. Ngophuhliso olukhawulezayo lwezenzululwazi kunye nobuchwepheshe, uxinzelelo kwiibheringi luye lwaba namandla kwaye luphezulu, kwaye iimfuno zomgangatho nazo ziya kuba phezulu.

Ingcamango kunye nokuhlelwa kweebheringi eziqengqelekayo

Iibheringi eziqhelekileyo eziqhelekileyo ziqulunqwe ngezinto ezisisiseko ezifana nezangqa ezimbini (oko kukuthi, i-ring yangaphakathi, i-ring yangaphandle), i-rolling elements kunye ne-cages.Ukuze kufakwe kwiimfuno ezikhethekileyo, ezinye iibheringi ziya kwanda okanye zinciphise ezinye iindawo.

Imisebenzi emine ye-Rolling Bearings

Indandatho yangaphakathi ivame ukuhambelana ngokuqinileyo kunye ne-shaft kwaye ijikeleza nge-shaft.

Iringi yangaphandle iqhele ukusebenzisana nomngxuma wesihlalo sokuthwala okanye iqokobhe lenxalenye yomatshini ukudlala indima exhasayo.

Izinto ezijikelezayo zilungelelaniswe ngokulinganayo phakathi kwamakhonkco angaphakathi nangaphandle ngoncedo lwe-cage, kunye nokuma komqolo wayo, ubungakanani kunye nobuninzi bunquma ngokuthe ngqo ukuthwala umthamo wokuthwala.

I-cage iyahlula ngokulinganayo izinto ezijikelezayo kwaye zikhokela izinto ezijikelezayo ukuhamba kwindlela echanekileyo.

"Ukutyhalela iibheringi zeenaliti"

Iibheringi ezahlukanayo zenziwe ngamakhonkco omdyarho, iirola zeenaliti kunye neendibano zekheji, kwaye zinokudityaniswa nezangqa zendlela yomdyarho enesitampu (W) okanye imisesane eshinyeneyo yomdyarho (WS). Iibheringi ezingahlukiyo ziibheringi ezidityanisiweyo ezenziwe ngamakhonkco omdyarho anesitampu esichanekileyo, iirola zeenaliti kunye neendibano zekheji. Olu hlobo lokuthwala lunokumelana nomthwalo we-axial unidirectional. Ithatha indawo encinci kwaye ihambelana noyilo oludibeneyo lomatshini. Uninzi lwazo lusebenzisa kuphela i-roller yenaliti kunye nezixhobo ze-cage, kwaye zisebenzisa indawo yokunyuka ye-shaft kunye nezindlu njengendawo yomdyarho.

“I-Tapered Roller Bearings“

Olu hlobo lokuthwala luxhotyiswe nge-truncated rollers, ezikhokelwa yiimbambo ezinkulu zendandatho yangaphakathi. Kuyilo, ii-vertices ze-conical surfaces zomphezulu weringi yangaphakathi yomdyarho, umphezulu weringi wangaphandle kunye ne-roller rolling surface intersect in a point on the beararing center line. Iibheringi zomqolo omnye zinokuthwala umthwalo we-radial kunye nomthwalo we-axial wendlela enye, kwaye iibheringi ze-double-row zinokuthwala umthwalo we-radial kunye nomthwalo we-axial weendlela ezimbini, kwaye zifanelekile ukuthwala umthwalo onzima kunye nomthwalo wempembelelo.

"Ii-Cylindrical Roller Bearings"

I-Cylindrical roller bearings inokwahlulwa ibe yi-single-row, i-double-row kunye ne-multi-row cylindrical roller bearings ngokwenani lemiqolo yezinto ezisetyenziswayo kwi-bearing. Phakathi kwabo, iibhereyidi ze-cylindrical roller ezine-cages zisetyenziswa ngokubanzi. Ukongezelela, kukho iibheringi ze-cylindrical roller kunye nezinye izakhiwo ezifana nomqolo omnye okanye umqolo ophindwe kabini ogcweleyo.

Umqolo omnye weebheringi ze-cylindrical roller zahlulwe ngohlobo lwe-N, uhlobo lwe-NU, uhlobo lwe-NJ, uhlobo lwe-NF kunye nohlobo lwe-NUP ngokweembambo ezahlukeneyo zeringi. Iibheringi ze-Cylindrical roller zinomthamo omkhulu we-radial load, kwaye ziyakwazi ukuthwala indlela enye okanye i-axial-way-way-axial load ngokwesakhiwo sombambo wendandatho. Uhlobo lwe-NN kunye nohlobo lwe-NNU lwe-double row cylindrical roller bearings luhlangene kwisakhiwo, luqinile ngokungqongqo, lukhulu ekuthwaleni umthamo kunye nomncinci kwi-deformation emva kokulayishwa, kwaye lusetyenziselwa kakhulu ukuxhasa izixhobo zokuphotha zomatshini. I-FC, i-FCD, i-FCDP yohlobo lwe-4-row cylindrical roller bearings inokumelana nemithwalo emikhulu ye-radial, kwaye isetyenziswa kakhulu koomatshini abanzima abafana nee-rolling Mills.

“Ukuthwala i-roller engqukuva“

Olu hlobo lokuthwala luxhotyiswe ngeerola ezingqukuva phakathi kwesangqa sangaphandle somdyarho ongqukuva kunye nomsesane wangaphakathi wendlela yokubaleka kabini. Ngokutsho kwezakhiwo ezahlukeneyo zangaphakathi, zihlulwe zibe ziindidi ezine: R, RH, RHA kunye ne-SR. Ekubeni i-arc center ye-raceway yangaphandle ihambelana neziko lokuthwala, inomsebenzi wokuziqhelanisa, ngoko unokulungelelanisa ngokuzenzekelayo ukungahambi kakuhle kwe-shaft okubangelwa ukuphambuka okanye ukungahambi kakuhle kwe-shaft okanye indlu. Iyakwazi ukuthwala umthwalo we-radial kunye nomthwalo we-axial we-bidirectional. Ngokukodwa, umthamo womthwalo we-radial mkhulu, kwaye ufanelekile ukuthwala imithwalo enzima kunye nemithwalo yothuso. I-Metal processing WeChat, umxholo ulungile, ufanelekile ukuqwalaselwa. Iibheringi ze-tapered bore zinokudityaniswa kwaye zichithwe kwi-shaft ngokusebenzisa i-fasteners okanye imikhono yokurhoxisa. Iibheringi ze-roller ezingqukuva zinokuthwala umthwalo omkhulu we-radial, kodwa zinokuthwala umthwalo othile we-axial. Umdyarho weringi wangaphandle wolu hlobo lokuthwala lungqukuva, ngoko ke unomsebenzi wokuzilungelelanisa. Xa i-shaft igobile okanye iyancipha phantsi kokunyanzeliswa, ukwenzela ukuba ukuthambekela komgca ophakathi kwendandatho yangaphakathi kunye nomgca ophakathi wendandatho yangaphandle ayidluli i-1 ° ~ 2.5 °, ukuthwala kusengasebenza. .

“I-Thrust Roller Bearing“

Iibheringi ze-thrust roller ziquka iibheringi ze-thrust spherical roller, iibheringi zerola ezityhutyhayo kunye neebheringi eziqengqelekayo. I-Thrust spherical roller bearings inokuthwala zombini imithwalo ye-axial kunye ne-radial, kodwa umthwalo we-radial awuyi kudlula i-55% yomthwalo we-axial. Olunye uphawu olubalulekileyo lolu hlobo lokuthwala luyi-self-aligning performance, eyenza ukuba ingabi namvakalelo yokungahambi kakuhle kunye nokuphambuka kwe-shaft. Ukulayisha nje i-P kunye ne-P. Akukho ngaphezu kwe-0.05C, kwaye i-shaft ring ijikeleza, ukuthwala kuvumela uluhlu oluthile lwe-angle yokulungelelanisa. Amaxabiso amancinci afanelekile kwiibheringi ezinkulu, kwaye i-angle yokulungelelanisa evumelekileyo iya kuncipha njengoko umthwalo usanda.

"Iibheringi eziSpherical"

Faka iibheringi ezingqukuva zikhethwa ngokufanelekileyo kwizicelo ezifuna izixhobo ezilula kunye namalungu, njengoomatshini bezolimo, iinkqubo zothutho okanye oomatshini bokwakha.

“Ukuthwala uQhagamshelwano lwe-Angular“

Iibhodi zebhola zoqhagamshelwano ze-Angular zinokuthwala umthwalo we-radial kunye nomthwalo we-axial ngexesha elifanayo, kwaye unokuthwala umthwalo ococekileyo we-axial, kwaye isantya somda siphezulu. Ikhono lolu hlobo lokuthwala ukuthwala umthwalo we-axial unqunywe yi-angle yoqhagamshelwano. Inkulu i-angle yoqhagamshelwano, iphezulu ukukwazi ukuthwala umthwalo we-axial.
