Umzekelo weshishini lephepha

Kwimveliso yamaphepha, iibheringi eziqengqelekayo kwii-CD-profile control rolls zoomatshini be-calender zihlala ziphantsi kwemithwalo ephantsi.Imithwalo iphezulu kuphela xa i-gap phakathi kwemiqulu ivulekile.Kwezi zicelo, abavelisi boomatshini ngokwesiko bakhetha iibheringi ezingqukuva ezingqukuva ezinomthamo owaneleyo wokuthwala umthwalo wesigaba somthwalo ophezulu.Nangona kunjalo, kwinqanaba lomthwalo ophantsi oku kukhokelele ekutyibilikeni, okukhokelela ekungaphumeleli kokuthwala kwangaphambi kwexesha.

Ngokugquma izinto eziqengqelekayo kunye nokwandisa ukuthambisa, ezi ziphumo zokutyibilika zinokuncitshiswa, kodwa zingapheliswa ngokupheleleyo.Ngesi sizathu, uSchaeffler uphuhlise i-ASSR ethwele (i-Anti-Slippage Spherical Rolling Bearing).Ibheringi ibandakanya iiringi zeebheringi eziqhelekileyo ezingqukuva, kodwa ii-barrel rollers zitshintshana ngeebhola kwimiqolo emibini yezinto eziqengqelekayo.Kwinqanaba eliphantsi lomthwalo, iibhola ziqinisekisa ukusebenza kwe-slippage-free, ngelixa i-barrel rollers ithatha imithwalo kwinqanaba eliphezulu lomthwalo.

Iinzuzo kumthengi zicacile: ngelixa iibheringi zangaphambili zifezekiseke ngokuqhelekileyo ubomi benkonzo malunga nonyaka omnye, iibheringi ezintsha ze-ASSR zilindeleke ukuba zihlale ukuya kwi-10 iminyaka.Oku kuthetha ukuba zimbalwa iibheringi eziqengqelekayo ezifunekayo kubomi bomatshini wekhalenda, ukuncitshiswa kweemfuno zogcino kunye nokugcinwa kweedijithi ezintandathu kumjikelo wobomi bomatshini.Konke oku kwaphunyezwa ngokuthathela ingqalelo indawo yomatshini omnye kuphela.Ukulungiswa okungaphezulu kwaye ngoko ke ukonga okongeziweyo okubalulekileyo kunokufezekiswa ngamanyathelo ongezelelweyo, njengokubeka iliso kwimeko ye-intanethi kunye nokuxilongwa kwe-vibration, ukubeka iliso lokushisa okanye ukulinganisa okuguquguqukayo / okuguquguqukayo - konke oku kunokubonelelwa nguSchaeffler.

Iiinjini zomoya kunye noomatshini bokwakha

Iibheringi ezininzi eziqengqelekayo ezivela kwi-Schaeffler ziyafumaneka kwintsebenzo ephezulu, i-premium quality X-life version.Ngokomzekelo, xa kuphuhliswa uchungechunge lwe-X-life of tapered roller bearings, ingqalelo ekhethekileyo ihlawulwe ekufezekiseni ukuthembeka okuphezulu kunye nokunciphisa ukungqubuzana, ngokukodwa kwizicelo zomthwalo ophezulu kunye nezo zifuna ukuchaneka okujikelezayo.Oku kuthetha ukuba abavelisi beeyunithi zehydraulic okanye iibhokisi zegiya (izixhaso ezithwele ipinion) ezifana nezo zifumaneka kwiiinjini zomoya, izithuthi zezolimo kunye noomatshini bokwakha, ngoku banokugqitha kwimida yokusebenza yangaphambili, ngelixa bephucula kakhulu ukhuseleko lokusebenza.Ngokubhekiselele ekunciphiseni, iimpawu eziphuculweyo ze-X-life bearings zithetha ukuba ukusebenza kwebhokisi yegiya kuphuculwe, ngelixa imvulophu yoyilo ihlala ifana.

Uphuculo lwama-20% kumlinganiselo womthwalo oguquguqukayo kunye nobuncinane obungama-70% bophuculo kubomi bohlelo olusisiseko luphunyezwe ngokuphucula ijometri, umgangatho womphezulu, imathiriyeli, ubungakanani kunye nokuhamba ngokuchanekileyo kweebheringi.

Izinto ezithwala i-premium ezisetyenziselwa ukuveliswa kwe-X-life tapered roller bearings zilungelelaniswe ngokukodwa ukuhlangabezana neemfuno zeebheringi ezijikelezayo kwaye yinto ebalulekileyo ekusebenzeni okwandisiweyo kweebheringi.Isakhiwo sengqolowa esilungileyo sesi sixhobo sinikeza ubunzima obuphezulu kwaye ngoko ke ukuchasana okuphezulu kwizinto ezingcolileyo eziqinileyo.Ukongezelela, iphrofayili ye-logarithmic yaphuhliswa kwi-raceways ethwele kunye nomphandle wangaphandle we-roller, ohlawulela ukunyanzeliswa kwengcinezelo ephezulu phantsi kwemithwalo ephezulu kunye nayiphi na "i-skewing" enokuthi yenzeke ngexesha lokusebenza.Ezi ndawo ziphuculweyo zincedisa ekwenziweni kwefilimu ye-elasto-hydrodynamic lubricant, nakwizantya eziphantsi kakhulu zokusebenza, ezenza ukuba iibheringi zikwazi ukumelana nemithwalo ephezulu ngexesha lokuqalisa.Ngaphaya koko, ukunyamezelwa kwe-dimensional kunye ne-geometrical okuphuculweyo kuqinisekisa ukuhanjiswa komthwalo okona kulungileyo.Iincopho zoxinzelelo ke ngoko ziyaphetshwa, okunciphisa ukulayishwa kwezinto.

I-torque ye-frictional entsha ye-X-life tapered roller bearings iye yancitshiswa ukuya kuthi ga kwi-50% xa kuthelekiswa neemveliso eziqhelekileyo.Oku kungenxa yokuchaneka komgangatho ophezulu kunye nokuhamba ngokudityaniswa nokuphucuka komgangatho womphezulu.I-geometry yoqhagamshelwano ehlaziyiweyo ye-rib yangaphakathi ye-rib kunye ne-roller end face iphinda incedise ekunciphiseni ukungqubuzana.Ngenxa yoko, ubushushu bokusebenza obuthweleyo buncitshiswe ukuya kuthi ga kwi-20%.

Iibheringi ze-X-life tapered roller azikho nje ukonga ngakumbi, kodwa zikhokelela kubushushu obuphantsi bokuthwala, nto leyo ebeka uxinzelelo oluncinci kwi-lubricant.Oku kwenza ukuba izithuba zolondolozo zandiswe kwaye kubangele ukuba iibheringi zisebenze kumanqanaba engxolo ancitshisiweyo.
