I-Sliding bearing iqonda intshukumo phakathi kweshaft kunye nokuthwala nge-Sliding friction, ngelixa i-rolling bearing iqonda intshukumo phakathi kwe-shaft kunye nokuthwala ngokusebenzisa ukungqubana okuqengqelekayo. Kwiibhola zebhola, ngenxa yeemeko zabo zokusebenza ezinzima kunye nesantya esiphezulu kunye neemfuno zomthwalo ophezulu, iibheringi eziqengqelekayo zikhethwa ngokubanzi.
Iibheringi eziqengqelekayo zineenzuzo ezininzi ezenza ukuba zilungele izicelo zokusila. Okokuqala, i-rolling friction incinci kune-Sliding friction, enokunciphisa ilahleko yamandla kunye nobushushu be-friction, kunye nokuphucula ukusebenza kakuhle komatshini. Okwesibini, ukunyakaza kweebheringi ezijikelezayo kuzinzile kwaye kunokumelana nomthwalo omkhulu we-radial kunye ne-axial, okwenza kube lula ukunyakaza okujikelezayo kwesantya esiphezulu. Ukongeza, iibheringi eziqengqelekayo nazo zineengenelo ezifana nobomi benkonzo ende kunye nolondolozo olufanelekileyo.
Kwiibhola zebhola, iibheringi eziqengqelekayo zidla ngokusetyenziselwa ukuxhasa iindawo ezithwele igubu kunye nesixhobo sokuhambisa. Bangakwazi ukumelana nokujikeleza kwesantya esiphezulu kunye nefuthe lempembelelo evela kwi-abrasives kunye nezixhobo zeendaba, ukuqinisekisa ukusebenza okuqhelekileyo kwezixhobo. Ngenxa yendawo enzima yokusebenza kweebhola zebhola, iibheringi zifunekayo ukuba zibe nokutywinwa okuphezulu kunye nobuchule bokukhusela uthuli ukukhusela i-abrasive kunye nemidiya ekungeneni ngaphakathi kweebheringi kunye nokuchaphazela ukusebenza kwazo.
Ngamafutshane, ukusetyenziswa kweebheringi ze-sliding kwi-rolling bearings kwii-mills zebhola kunokuphucula ukuthembeka kunye nokusebenza kakuhle kwezixhobo, ukwandisa ubomi benkonzo yeebheringi, kunye nokunciphisa iindleko zokugcina.
Ezi zilandelayo ziziphene eziphambili zeebheringi zokutyibilika:
1. I-Friction kunye nokunxiba: Iibheringi zokutyibilika zinciphisa uqhagamshelwano phakathi kwe-sliding kunye ne-rolling parts ngokusebenzisa i-friction, kodwa ukungqubuzana kunokukhokelela ekulahlekelweni kwamandla kunye nokunxiba kwecandelo, ngaloo ndlela kuncitshiswe ukuthwala ubomi kunye nokusebenza kakuhle.
2. Iimfuno eziphezulu zokuthambisa: Iibheringi ze-sliding kufuneka zigcine i-lubricant eyaneleyo yokunciphisa i-friction kunye nokugqoka, ngoko ke kuyimfuneko ukongeza rhoqo kunye nokutshintsha i-lubricants, okwandisa iindleko zokugcinwa kunye nomsebenzi.
3. Ubunzima bokuvelisa ubushushu kunye nokuchithwa: Ngenxa yokuxhatshazwa, iibheringi ezityibilikayo zivelisa ubushushu, kwaye ngenxa yendawo enkulu yokudibanisa, ukutshatyalaliswa kobushushu kuhamba ngokukhawuleza. Oku kunokubangela ukufudumala kweebheringi kunye namacandelo akufutshane, okuchaphazela ukuzinza kokusebenza kunye nobomi besixhobo.
4. Ayifanelekanga kwisantya esiphezulu sokusebenza: Ngenxa yokuxinwa kwendawo kunye nokuchithwa kwee-lubricants, ii-bearings ze-sliding zijongene nokungaphumeleli kwe-lubrication kwi-speed speed, echaphazela ukuzinza kwabo kunye nobomi benkonzo, kwaye ayifanelekanga kwizicelo ze-high-speed operation.
5. Ukungcangcazela kunye nengxolo: Ngethuba lokusebenza kweebheringi ze-sliding, i-vibration kunye nengxolo yenziwa ngokulula ngenxa yobukho be-friction, echaphazela ngakumbi ukuzinza kwezixhobo kunye nendawo yokusebenza.
6. Ubunzima ekugcinweni nasekulungiseni: Isakhiwo se-sliding bearings sinzima kwaye ngokuqhelekileyo sifuna ukugcinwa nokulungiswa, okudla ixesha elininzi kunye neendleko zomsebenzi.
Isishwankathelo, iziphene eziphambili zeebheringi ze-sliding ziquka ukungqubuzana kunye nokugqoka, iimfuno eziphezulu zokuthambisa, ubunzima bokuvelisa ukushisa kunye nokuchithwa, okungafanelekanga ekusebenzeni kwesantya esiphezulu, ukungcangcazela kunye nengxolo, kunye nobunzima bokugcinwa nokulungiswa.
Iingenelo eziphambili zokuqengqeleka kweebheringi zezi:
1. Ukusetyenziswa kwamandla aphantsi, ukusebenzisa ii-rolling bearings endaweni ye-sliding bearings kunciphisa ukusetyenziswa kwamandla kwebhola lebhola malunga ne-10%.
2. Kulula ukuqhaqha. Ukwamkela idizayini ekhethekileyo yomkhono we-cone, ukufakela kulula kakhulu, ukuphepha ukukrazula kunye nokusebenza kokugaya kweebheringi eziqengqelekayo, okwenza kube lula ukuyigcina.
3. Ubomi benkonzo ende. Ngenxa yokuba ukukhethwa kweebheringi kwiibhola zebhola kunokusekwa kuphela kumthamo wokucubungula okanye ukukhutshwa kwe-ore, iibheringi ezikhethiweyo zigqithisa kakhulu umthamo wazo owenziweyo. Ngoko ke, ubomi benkonzo yeebheringi ezijikelezayo kwiibhola zebhola zihlala zide kuneebhola zebhola, kwaye ukusebenza kwazo kuhle.
4. Indlela ye-lubrication ilula, kwaye ii-rolling bearings zixutywe nge-lubricating grease, efuna kuphela ukongeza rhoqo, ukuqinisekisa ukuthambisa okuthembekileyo.
Ngoko ke, ukusetyenziswa kweebheringi ezijikelezayo kwiibhola zebhola kuneenzuzo ezintle zoqoqosho. Akunakuphela nje ukuchasana kwe-friction ephantsi, ukusetyenziswa kwamandla aphantsi, ukusebenza okuphantsi kwangoku, ukuqala okuzinzile, kodwa kunemiphumo ebalulekileyo yokonga amandla, ukunciphisa izibonelelo ezixhasayo, kunye nokugcina iindleko.
