Ukuthelekiswa kweebheringi eziqengqelekayo kunye neebheringi ezicacileyo

Ukusetyenziswa kweiibheringi, iimpawu zokukhuhlana kweebheringi ezikhwelayo zinokwahlulwa zibe ziibheringi eziqengqelekayo kunye neebheringi ezityibilikayo, sinokukhetha iintlobo ezahlukeneyo zokuthwala ngokweemfuno ezithile zokusetyenziswa, iibheringi eziqengqelekayo kunye neebheringi ezityibilikayo zineempawu ezahlukeneyo zokusetyenziswa,

Iimpawu eziphambili zeiibheringi eziqengqelekayozezi:

1. Ukudambisa i-friction encinci (ngokunxulumene ne-non-liquid friction sliding bearing), ukuqalisa okuguquguqukayo;

2. Iyakwazi ukuthwala imithwalo ye-radial kunye ne-axial ngexesha elifanayo, ukwenza lula isakhiwo esixhasayo;

3. Ukukhutshwa kwe-radial kuncinci, kwaye ukukhutshwa kunokupheliswa kwakhona yindlela yokulayishwa kwangaphambili, ngoko ukuchaneka kokujikeleza kuphezulu;

4. Ukutshintshana okulungileyo kunye nokugcinwa lula.

 

Iimpawu eziphambili zeiibheringi ezicacileyozezi:

1. Umsebenzi ozinzileyo kwaye akukho ngxolo;

2. Ukuchaneka okuphezulu kokujikeleza;

3. Ilahleko encinci ye-friction ngexesha lokuthambisa ulwelo;

4. Ubungakanani obuncinci be-radial;

5. Umthamo ophezulu wokuthwala.

 

Ziziphi iingenelo kunye nokungalunganga kweebheringi eziqengqelekayo xa kuthelekiswa neebheringi ezithafa? Uhlalutyo luhamba ngolu hlobo lulandelayo:

 

Xa kuthelekiswa neebheringi ezicacileyo, iibheringi eziqengqelekayo zineenzuzo zilandelayo:

1. I-coefficient ye-friction ye-rolling bearings incinci kune-sliding bearings, kunye nokusebenza kakuhle kokuhanjiswa kuphezulu. Ngokuqhelekileyo, i-coefficient ye-friction ye-sliding bearings yi-0.08-0.12, ngelixa i-friction coefficient of rolling bearings yi-0.001-0.005 kuphela;

2. Iibheringi eziqengqelekayo zibekwe emgangathweni, zilungelelanisiwe kwaye zilungelelaniswe ngokubanzi, zilungele imveliso yobuninzi kunye nokubonelela, kwaye kulula kakhulu ukuyisebenzisa nokugcina;

3. Iibheringi eziqengqelekayo zenziwe ngentsimbi yokuthwala kwaye ziphantsi konyango lobushushu, ngoko ke iibheringi eziqengqelekayo azinayo nje iipropathi eziphakamileyo zoomatshini kunye nobomi obude benkonzo, kodwa kunokonga iintsimbi ezibiza kakhulu ezingezizo ezisetyenziselwa ukwenziwa kweebheringi zokutyibiliza;

4. Ukukhutshwa kwangaphakathi kwe-rolling bearing kuncinci kakhulu, kwaye ukuchaneka kwe-machining yecandelo ngalinye kuphezulu, ngoko ke ukuchaneka kokuhamba kuphezulu. Ngexesha elifanayo, ukuqina kokuthwala kunokunyuswa ngokulayishwa kwangaphambili. Oku kubaluleke kakhulu koomatshini abachanekileyo;

5. Ezinye iibheringi eziqengqelekayo zinokuthwala umthwalo we-radial kunye nomthwalo we-axial ngexesha elifanayo, ngoko ke ukwakhiwa kwe-bearing bearing kungenziwa lula;

6. Ngenxa yokuhanjiswa okuphezulu kunye nokuveliswa kobushushu obuphantsi beebheringi eziqengqelekayo, ukusetyenziswa kweoyile yokuthambisa kungancitshiswa, kwaye i-lubrication kunye nokugcinwa kulula ngakumbi;

7. Iibheringi eziqengqelekayo zinokufakwa lula kwiuranium nakweliphi na icala lendawo.

 

 

Nangona kunjalo, yonke into yahlulwe kabini, kwaye iibheringi eziqengqelekayo nazo zinento engalunganga, ezona ziphambili zezi:

1. Umthamo wokuthwala umthwalo we-rolling bearings uncinci kakhulu kuneebheringi ze-sliding zomthamo ofanayo, ngoko ke, ubukhulu be-radial of rolling bearings bukhulu. Ngoko ke, ngexesha lokuthwala umthwalo omkhulu kunye nesiganeko esifuna ubungakanani obuncinci be-radial kunye nesakhiwo esihlangeneyo (njenge-injini yokutshisa yangaphakathi ye-crankshaft bearing), ii-sliding bearings zisetyenziswa kakhulu;

2. I-vibration kunye nengxolo yeebheringi ezijikelezayo zinkulu, ngakumbi kwinqanaba lokugqibela lokusetyenziswa, ngoko ke, xa iimfuno ezichanekileyo ziphezulu kakhulu kwaye ukungcangcazela akuvumelekanga, iibheringi ezijikelezayo zinzima ukuba zikwazi ukufaneleka, kwaye umphumo we-sliding bearings. ngcono ngokubanzi;

3. Iibheringi eziqengqelekayo zinovelwano ngakumbi kwimizimba yangaphandle efana neetshiphu zetsimbi, kwaye nje ukuba izinto zangaphandle zingene kwibheringi, ziya kuvelisa ukungcangcazela okukhulu kunye nengxolo, okuya kubangela umonakalo kwangethuba. Ukongeza, iibheringi eziqengqelekayo nazo zichaphazeleka kumonakalo kwangethuba ngenxa yokufakwa kwentsimbi. Nokuba umonakalo wangaphambili ungenzeki, kukho umda kubomi bokuqengqeleka kweebheringi. Ngamafutshane, iibheringi eziqengqelekayo zinobomi obufutshane benkonzo kuneebheringi ezicacileyo.

 

Xa kuthelekiswa neebheringi eziqengqelekayo kunye neebheringi ezityibilikayo, nganye ineengenelo zayo kunye nezingeloncedo zayo, kwaye nganye ithatha isihlandlo esithile esisebenzayo, ke ngoko, ezi zimbini azinakutshintsha ngokupheleleyo, kwaye nganye iphuhlisa kwicala elithile kwaye yandise intsimi yayo. Nangona kunjalo, ngenxa yeenzuzo ezibalaseleyo zokuqengqeleka kweebheringi, kukho umkhwa wokuba abo bafika emva kwexesha baphumelele. Okwangoku, iibheringi eziqengqelekayo ziye zaphuhliswa zaba yeyona nto iphambili yokuxhasa oomatshini, kwaye isetyenziswa ngokubanzi.
