Ukukhethwa kohlobo lokuthwala Iimodeli ezisetyenziswa ngokuqhelekileyo eziqengqelekayo kwiimotor ziibhola ze-groove groove ezinzulu, iibheringi ze-cylindrical roller, iibheringi ezingqukuva, kunye neebheringi zeebhola zoqhagamshelwano.Iibheringi kuzo zombini iziphelo zeenjini ezincinci zisebenzisa iibheringi zebhola zegroove ezinzulu, iinjini ezinobungakanani obuphakathi zisebenzisa iibheringi eziqengqelekayo ekupheleni komthwalo (ngokuqhelekileyo zisetyenziselwa iimeko zomthwalo ophezulu), kunye neebhola ekungangeni komthwalo (kodwa kukwakho namatyala achaseneyo). , njengeenjini eziyi-1050kW).Iinjini ezincinci nazo zisebenzisa iibheringi zeebhola zoqhagamshelwano.Iibheringi ze-roller ezizii-Spherical zisetyenziswa ikakhulu kwiinjini ezinkulu okanye kwiinjini ezithe nkqo.Iibheringi zeemotoIfuna isandi esingaqhelekanga, ukungcangcazela okuphantsi, ingxolo ephantsi, kunye nokunyuka kobushushu obuphantsi.Ngokuhambelana nemithetho yokukhetha kwitheyibhile engezantsi, ezi zinto zilandelayo zidla ngokuqwalaselwa ukuhlalutya indlela yokukhethwa kweprojekthi.Indawo yokufakela i-bearing ingakwazi ukuthwala ubungakanani besayizi kwindawo yokufakela.Ngenxa yokuba ukuqina kunye namandla e-shaft kugxininiswe xa kuyilwa inkqubo ye-shaft, ububanzi be-shaft ngokuqhelekileyo bumiselwa kuqala.Nangona kunjalo, kukho uluhlu oluhlukeneyo lobungakanani kunye neentlobo zeebheringi ezijikelezayo, apho kufuneka kukhethwe imilinganiselo efanelekileyo yokuthwala.

Umthwalo Ubungakanani, ulwalathiso kunye nohlobo lomthwalo wokuthwala [umthamo womthwalo wokuthwala ubonakaliswa ngumthwalo olinganiselweyo osisiseko, kwaye ixabiso lawo liboniswa kwitheyibhile yobungakanani bokuthwala] Umthwalo wokuthwala ugcwele utshintsho, njengobukhulu be umthwalo, nokuba kukho umthwalo we-radial kuphela, kwaye ingaba umthwalo we-axial ungowomnye ulwalathiso okanye indlela ezimbini, iqondo lokungcangcazela okanye ukothuka, njalo njalo.Emva kokuqwalasela le miba, khetha uhlobo olufanelekileyo lwesakhiwo sokuthwala.Ngokuqhelekileyo, umthwalo we-radial weebheringi ze-NSK ezinomlinganiselo ofanayo wangaphakathi uyahluka ngokwechungechunge, kwaye umthwalo olinganisiweyo unokutshekishwa ngokwesampuli.Uhlobo lokuthwala isantya esinokuthi sihambelane nesantya somatshini [ixabiso lomda wesantya sokuthwala libonakaliswa ngesantya somda, kwaye ixabiso lalo liboniswa kwitheyibhile yobungakanani bokuthwala] Isantya somda wokuthwala asixhomekeke kuphela kuhlobo lokuthwala , kodwa kwakhona kunqunyelwe ubungakanani bokuthwala, uhlobo lwekheji, kunye nenqanaba lokuchaneka , iimeko zomthwalo kunye neendlela zokuthambisa, njl., Ngoko ke, ezi zinto kufuneka ziqwalaselwe xa ukhetha.Iibheringi zesakhiwo esifanayo kunye nobubanzi obungaphakathi be-50 ~ 100mm zinesantya esiphezulu somda;ukuchaneka kokujikeleza kunokuchaneka okufunekayo okujikelezayo kohlobo lokuthwala [ukuchaneka kobungakanani kunye nokuchaneka kokujikeleza kwe-bearing kuye kwamiselwa i-GB ngokohlobo lokuthwala].

Ukuchaneka kokuthwala kunqunywe ngokomlinganiselo wesantya ukuya kumda wesantya.Ukuphakama kokuchaneka, ukuphakama kwesantya somda kunye nokuncinci kwesizukulwana sobushushu.Ukuba idlula i-70% yesantya somda we-bearing, ibakala elichanekileyo lokuthwala kufuneka liphuculwe.Ngaphantsi kwe-radial clearance efanayo yantlandlolo, incinci isizukulwana sobushushu, ukuthambekela okuhlobene kweringi yangaphakathi kunye neringi yangaphandle.Uhlalutyo lwezinto ezibangela ukuthambekela okuhambelanayo kweringi yangaphakathi kunye neringi yangaphandle yokuthwala (njengokuphambuka kwe-shaft okubangelwa ngumthwalo, ukungachaneki kakuhle kwe-shaft kunye nezindlu) Okanye impazamo yofakelo), kwaye ukhethe uhlobo lokuthwala. enokuziqhelanisa nale meko yenkonzo.Ukuba ukuthambekela kwesihlobo phakathi kwendandatho yangaphakathi kunye nendandatho yangaphandle inkulu kakhulu, ukuthwala kuya konakala ngenxa yomthwalo wangaphakathi.Ngoko ke, i-self-aligning roller bearring enokumelana nolu tyekelo kufuneka ikhethwe.Ukuba ukuthambekela kuncinci, ezinye iintlobo zeebheringi zingakhethwa.Indlela yokukhethwa kwezinto zokuhlalutya I-shaft yokucwangcisa i-bearing ixhaswa ngamabhobho amabini kwi-radial kunye ne-axial directions, kwaye elinye icala liyi-fixed side side, ethwala imithwalo ye-radial kunye ne-axial., edlala indima kwintshukumo ye-axial ehambelanayo phakathi kwe-shaft esisigxina kunye nezindlu zokuthwala.Elinye icala licala elikhululekileyo, elithwala kuphela umthwalo we-radial kwaye likwazi ukuhamba ngokulinganayo kwi-axial direction, ukwenzela ukusombulula ingxaki yokwandiswa kunye nokunciphisa i-shaft ebangelwa utshintsho lweqondo lokushisa kunye nephutha lezithuba zeebheringi ezifakiwe.Kwii-shafts ezimfutshane, i-fixed side ayibonakali ukusuka kwicala lamahhala.

I-fixed-end bearing ikhethwa kwi-axial positioning kunye nokulungiswa komthwalo wokuthwala umthwalo we-axial we-bidirectional.Ngethuba lokufakela, amandla ahambelanayo kufuneka athathelwe ingqalelo ngokobukhulu bomthwalo we-axial.Ngokuqhelekileyo, iibhola zebhola zikhethwa njengesiphelo esisisigxina kunye neebheringi ezikhululekile zikhethwa ukuphepha.Ukwandiswa kunye nokucutheka kwe-shaft okubangelwa utshintsho lobushushu ngexesha lokusebenza, kunye nesikhundla se-axial esisetyenziselwa ukulungelelanisa ukuthwala kufuneka ithwale imithwalo ye-radial kuphela, kwaye i-ring yangaphandle kunye neqokobhe ngokubanzi zithatha indawo yokucima, ukuze i-shaft ibe ne-axially. kuphetshwa kunye nokuthwala xa i-shaft isanda., Ngamanye amaxesha ukuphepha kwe-axial kwenziwa ngokusebenzisa indawo ehambelanayo ye-shaft kunye nendandatho yangaphakathi.Ngokuqhelekileyo, ukuthwala i-cylindrical roller kukhethwe njengesiphelo samahhala kungakhathaliseki ukuba sisiphi na isiphelo esisisigxina kunye nesiphelo samahhala.Xa ukuthwala kukhethiweyo, xa umgama phakathi kweebheringi uncinci kwaye impembelelo yokwandiswa kwe-shaft incinci, sebenzisa amantongomane okanye ama-washers ukulungelelanisa i-axial clearance emva kokufakwa.Ngokuqhelekileyo, ezimbini zikhethwa.Iibhodi zebhola ze-groove ezinzulu okanye iibherethi ezimbini ze-spherical roller zingasetyenziselwa njengenkxaso yesiphelo esisisigxina kunye nesiphelo samahhala okanye xa kungekho mahluko phakathi kwesiphelo esisisigxina kunye nesiphelo samahhala.Ukunyuswa kunye nokwehliswa kwamatyeli kunye nendlela yokunyuswa kunye nokwehliswa, njengokuhlolwa rhoqo, izixhobo zokunyuswa kunye nokwehliswa ziyafuneka xa kunyuswa kunye nokwehliswa.Isantya kunye nomthwalo zizinto ezimbini ezibalulekileyo.Ngokuthelekisa phakathi kwesantya kunye nokujikeleza komda, kunye nokuthelekisa phakathi komthwalo ofunyenweyo kunye nomthwalo olinganisiweyo, oko kukuthi, ubomi bokukhathala obulinganisiweyo, ifom yesakhiwo sokuthwala inqunywe.Ezi zinto zimbini zibalaseliswe ngezantsi.
