Iibheringi eziqengqelekayo zizinto ezibalulekileyo kwizicelo ezahlukeneyo zoshishino, zibonelela ngenkxaso kwaye zinciphisa ukungqubana phakathi kweendawo ezihambayo. Kwiindawo apho kukho iigesi eziqhumayo okanye uthuli,iibheringi eziqengqelekayo ezingaqhumiyozibalulekile ukuqinisekisa ukhuseleko kunye nokuthintela iingozi ezinokubakho. Ezi bearing ezikhethekileyo zenzelwe ukumelana nemingeni ebangelwa yimozulu eqhumayo, nto leyo eyenza ukuba zibe yinto ebalulekileyo kumashishini afana neoyile negesi, ukucutshungulwa kweekhemikhali, ukumbiwa kwemigodi, nokunye.
Ingcamango yee-rolling bearings ezingakwaziyo ukuqhuma ijikeleza kubuchule bazo bokuthintela ukutsha kwezinto ezinokutsha emoyeni ojikelezileyo. Oku kufezekiswa ngokusebenzisa izinto eziqinileyo, iindawo zokukhusela, kunye nemigangatho yoyilo engqongqo enciphisa umngcipheko wokutsha okanye ukutshisa kakhulu. Nangona kunjalo, kubalulekile ukuqaphela ukuba nangona ii-motor ezingakwaziyo ukuqhuma zisetyenziswa kakhulu kwiindawo ezinobungozi, inqanaba elifanayo lokhuseleko alinakusetyenziswa kwii-rolling bearings. Oku kuphakamisa umbuzo: kutheni ii-motor ezinamandla aphezulu ezingakwaziyo ukuqhuma zingasetyenziswa njengee-rolling bearings?
Ukuze siqonde lo mda, kubalulekile ukuphonononga imingeni ethile kunye neemfuno ezinxulumene neebheringi eziqengqelekayo ezingaqhumiyo. Ngokungafaniyo neemoto, ezigxila kakhulu ekuqulatheni imithombo enokubakho yokutsha ngaphakathi kwiindawo zazo ezibiyelweyo, iibheringi eziqengqelekayo zijongene neemfuno ezizodwa zokusebenza ezenza ukuba ukufikelela kubuchule bokutshayeleka kube nzima ngakumbi.
Esinye sezizathu eziphambili zokuba iimoto ezinamandla aphezulu angenakusetyenziswa ngokuthe ngqo njengee-rolling bearings ngumahluko kwiimeko zazo zokusebenza kunye nohlobo lokunxibelelana kwazo nendawo engqongileyo. Iimoto ziinkqubo ezivaliweyo ezinokwenziwa ukuthintela ukukhutshwa kweentlantsi okanye iindawo ezishushu, ngaloo ndlela kunciphisa umngcipheko wokutshisa izinto ezinokutsha. Ngokwahlukileyo koko, ii-rolling bearings zichatshazelwa yimeko-bume yangaphandle kwaye kufuneka zilwe nokungena kweegesi ezinokuba yingozi okanye amasuntswana othuli.
Ngaphezu koko, iimfuno zoomatshini zeebheringi eziqengqelekayo, ezinje ngomthamo wokuthwala umthwalo, isantya sokujikeleza, kunye nokuthambisa, zifuna indlela eyahlukileyo yokufezekisa amandla okumelana nokuqhuma. Ngelixa iimoto zinokuxhomekeka kuyilo lwendawo ebiyelweyo kunye namanyathelo okukhusela angaphakathi, iibheringi eziqengqelekayo kufuneka zijongane nomngcipheko wokuqhuma okanye ukuveliswa kobushushu kwiindawo zoqhagamshelwano phakathi kwezinto eziqengqelekayo kunye neendlela zomdyarho, kunye nangaphakathi kwenkqubo yokuthambisa.
Enye into ebalulekileyo ekufuneka iqwalaselwe bubungakanani kunye nobunzima beebheringi eziqengqelekayo xa kuthelekiswa neemoto. Iibheringi eziqengqelekayo zihlala zizinto ezincinci, ezicwangciswe ngokuchanekileyo ezisebenza phantsi kwemithwalo ephezulu kunye nesantya sokujikeleza. Ukufezekisa iimpawu ezingenakugqabhuka kwindawo exineneyo ngelixa kugcinwa iimpawu zokusebenza ezifunekayo kuzisa umngeni omkhulu wobunjineli. Ngokwahlukileyo koko, iimoto zineendawo ezinkulu ezinokuthi zilungiselele amanyathelo okukhusela ngokufanelekileyo.
Ukongeza kumahluko osebenzayo, imigangatho kunye nemigaqo elawula izixhobo ezikhusela ukuqhumaiimotokwaye iibheringi eziqengqelekayo nazo ziyahluka. Iimoto zixhomekeke kwiimfuno ezithile zesatifikethi kunye neenkqubo zovavanyo ezenzelwe uyilo kunye nomsebenzi wazo. Kwelinye icala, iibheringi eziqengqelekayo ezingenakugqabhuka kufuneka zilandele imigangatho eyahlukileyo ejongene neemeko zazo zokusebenza ezizodwa kunye nemithombo enokubakho yokutsha.
Ngenxa yezi ngxaki kunye neemfuno ezahlukeneyo zokusebenza, kuyacaca ukuba uyilo kunye nokusetyenziswa kwezakhono zokumelana nokuqhuma kwee-rolling bearings akunakulinganiswa ngokuthe ngqo nezo zeemoto ezinamandla aphezulu. Endaweni yoko, kufuneka iindlela ezikhethekileyo kunye nobuchwepheshe ukuqinisekisa ukuba ii-rolling bearings zinokusebenza ngokukhuselekileyo nangokuthembekileyo kwiindawo eziqhumayo.
Ukujongana nemingeni enxulumene neebheringi eziqengqelekayo ezingaqhumiyo, abavelisi baphuhlise izisombululo ezintsha ezidibanisa izixhobo eziphambili, izinto zokukhusela, kunye neendlela ezikhethekileyo zokuvala. Olu phuculo lujolise ekunciphiseni umngcipheko wokutsha, ukunciphisa ubushushu obunokungqubana, kunye nokuthintela ukungena kwezinto ezinobungozi, ngaloo ndlela kuphucula ukhuseleko kunye nokusebenza kweebheringi eziqengqelekayo kwiindawo eziqhumayo.
Umzekelo, ukusetyenziswa kwezinto ezingatshisi i-spark, ezifana nezinto zokuqengqeleka ze-ceramic kunye neengubo, kunokunciphisa kakhulu amandla okutsha kwizicelo zeebhearing eziqengqelekayo. Ngokufanayo, iinkqubo zokuvala eziphambili, kuquka ii-labyrinth seals kunye neengubo zokuthintela, zinceda ukuthintela ukungena kweegesi ezivuthayo okanye uthuli ngelixa zigcina ukuthambisa okufunekayo ukuze kusebenze kakuhle.
Ngaphezu koko, uphuhliso lwezithambiso ezikhethekileyo ezivelisa ubushushu obuphantsi kunye nokuzinza kobushushu okuphuculweyo kube negalelo elikhulu ekuphuculeni ukhuseleko kunye nokuthembeka kwee-rolling bearings ezikwaziyo ukuqhuma. Ezi zithambiso zenzelwe ngokukodwa ukumelana nemingeni yemozulu eqhumayo, ukuqinisekisa ukuba ii-bearings zinokusebenza ngaphakathi kwemida yobushushu efunekayo ngaphandle kokubeka umngcipheko wokutsha.
Ukuqukumbela, nangona iimoto ezinamandla aphezulu ezikhusela ukuqhuma kunye neebheringi eziqengqelekayo zombini zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kwiindawo ezinobungozi, iimfuno zazo zokusebenza ezahlukeneyo kunye neengqwalasela zoyilo zithintela ukusetyenziswa ngokuthe ngqo kwezakhono ezikhusela ukuqhuma ukusuka kwenye ukuya kwenye. Imingeni eyahlukileyo enxulumene neebheringi eziqengqelekayo ifuna izisombululo ezikhethekileyo ezijongana nobunzima bokusebenza kwiindawo eziqhumayo ngelixa zigcina iimpawu zokusebenza ezifunekayo. Ngokusebenzisa izixhobo eziphambili, amanyathelo okukhusela, kunye nobuchwepheshe obutsha, abavelisi bayaqhubeka nokuphucula ukhuseleko kunye nokuthembeka kweebheringi eziqengqelekayo ezikhusela ukuqhuma, benegalelo kukhuseleko olupheleleyo kunye nokusebenza kakuhle kwemisebenzi yemizi-mveliso kwiindawo ezinobungozi.
