Uthelekiso lweebheringi eziqengqelekayo kunye neebheringi ezicacileyo

Ukusetyenziswa kweiibheringi, iipropati zokungqubana kweebheringi zokufaka zingahlulwa zibe ziibheringi eziqengqelekayo kunye neebheringi ezityibilikayo, singakhetha iintlobo ezahlukeneyo zeebheringi ngokweemfuno ezithile zokusetyenziswa, iibheringi eziqengqelekayo kunye neebheringi ezityibilikayo zineempawu ezahlukeneyo zokusetyenziswa,

Iimpawu eziphambili zeiibheringi eziqengqelekayozezi:

1. Ukudambisa okuncinci kokungqubana (xa kuthelekiswa nokuthwala okungelulo ulwelo lokungqubana), ukuqala okuguquguqukayo;

2. Ingathwala imithwalo ye-radial kunye ne-axial ngaxeshanye, ilula isakhiwo esixhasayo;

3. Indawo yokungena kwe-radial incinci, kwaye indawo yokungena ingasuswa ngendlela yokulayisha kwangaphambili, ngoko ke ukuchaneka kokujikeleza kuphezulu;

4. Ukutshintshana kakuhle kunye nokugcinwa okulula.

 

Iimpawu eziphambili zeiibheringi ezingenantozezi:

1. Umsebenzi ozinzileyo kwaye akukho ngxolo;

2. Ukuchaneka okuphezulu kokujikeleza;

3. Ukulahleka okuncinci kokungqubana ngexesha lokuthambisa ulwelo;

4. Ubungakanani obuncinci be-radial;

5. Umthamo ophezulu wokuthwala.

 

Zithini iingenelo kunye neengxaki zeebhereyi eziqengqelekayo xa zithelekiswa neebhereyi ezingenanto? Uhlalutyo lulandelayo:

 

Xa kuthelekiswa neebheringi ezicacileyo, iibheringi eziqengqelekayo zinezibonelelo ezilandelayo:

1. I-coefficient ye-friction yee-rolling bearings incinci kuneye-sliding bearings, kwaye ukusebenza kakuhle kokudluliselwa kuphezulu. Ngokubanzi, i-coefficient ye-friction yee-sliding bearings yi-0.08-0.12, ngelixa i-coefficient ye-friction yee-rolling bearings yi-0.001-0.005 kuphela;

2. Iibheringi eziqengqelekayo ziye zalinganiswa, zahlulwahlulwa kwaye zaza zasetyenziswa ngokubanzi, zifanelekile kwimveliso enkulu kunye nobonelelo, kwaye zilula kakhulu ukuzisebenzisa nokuzigcina;

3. Iibheringi eziqengqelekayo zenziwe ngentsimbi yokuthwala kwaye zinyangwa ngobushushu, ngoko ke iibheringi eziqengqelekayo azinazo nje kuphela iimpawu eziphezulu zoomatshini kunye nobomi benkonzo ende, kodwa zinokusindisa neentsimbi ezingabizi kakhulu ezisetyenziswa ekwenzeni iibheringi ezityibilikayo;

4. Ukususwa kwangaphakathi kwebheriya yokuqengqeleka kuncinci kakhulu, kwaye ukuchaneka komatshini kwenxalenye nganye kuphezulu, ngoko ke ukuchaneka kokusebenza kuphezulu. Kwangaxeshanye, ukuqina kwebheriya kunokwandiswa ngokulayisha kwangaphambili. Oku kubaluleke kakhulu kumatshini ochanekileyo;

5. Ezinye iibheringi eziqengqelekayo zinokuthwala umthwalo we-radial kunye nomthwalo we-axial ngaxeshanye, ngoko ke ulwakhiwo lwebheringi lunokwenziwa lula;

6. Ngenxa yokusebenza kakuhle kokudlulisa kunye nokuveliswa kobushushu obuphantsi kweebheringi eziqengqelekayo, ukusetyenziswa kweoyile yokuthambisa kunokuncipha, kwaye ukuthambisa kunye nokugcinwa kulula ngakumbi;

7. Iibheringi eziqengqelekayo zingasetyenziswa ngokulula kwi-uranium nakweyiphi na indlela yesithuba.

 

 

Nangona kunjalo, yonke into yahlulwe kabini, kwaye iibheringi eziqengqelekayo nazo zineengxaki ezithile, ezona ziphambili zezi:

1. Umthamo wokuthwala umthwalo weebheringi eziqengqelekayo mncinci kakhulu kunoweebheringi eziqengqelekayo zomthamo ofanayo, ngoko ke, ubungakanani beradial beebheringi eziqengqelekayo bukhulu. Ke ngoko, kwimeko yokuthwala umthwalo omkhulu kunye nesiganeko esifuna ubungakanani beradingi encinci kunye nesakhiwo esincinci (njenge-crankshaft bearing yenjini yokutsha yangaphakathi), iibheringi eziqengqelekayo zisetyenziswa kakhulu;

2. Ukungcangcazela kunye nengxolo yeebheringi eziqengqelekayo zikhulu, ingakumbi kwinqanaba lokugqibela lokusetyenziswa, ngoko ke, xa iimfuno zokuchaneka ziphezulu kakhulu kwaye ukungcangcazela kungavumelekanga, iibheringi eziqengqelekayo kunzima ukuzenza kakuhle, kwaye isiphumo seebheringi ezityibilikayo ngokubanzi singcono;

3. Ii-rolling bearings zinovelwano kakhulu kwizinto zangaphandle ezifana neetships zesinyithi, kwaye xa izinto zangaphandle zingena kwi-bearings, ziya kuvelisa ukungcangcazela okukhulu kunye nengxolo eqhubekayo, eya kubangela nomonakalo kwangethuba. Ukongeza, ii-rolling bearings nazo zisengozini yomonakalo kwangethuba ngenxa yokufakwa kwesinyithi. Nokuba umonakalo wangethuba awukho, kukho umda wobomi bee-rolling bearings. Ngamafutshane, ii-rolling bearings zinobomi obufutshane benkonzo kunee-plain bearings.

 

Xa kuthelekiswa neebheringi eziqengqelekayo kunye neebheringi ezityibilikayo, nganye ineengenelo kunye neengxaki zayo, kwaye nganye ithatha ithuba elithile elifanelekileyo, ngoko ke, ezi zimbini azinakutshintshana ngokupheleleyo, kwaye nganye iphuhla kwicala elithile kwaye yandisa intsimi yayo. Nangona kunjalo, ngenxa yeengenelo ezibalaseleyo zeebheringi eziqengqelekayo, kukho umkhwa wokuba abantu abafika emva kwexesha baphumelele. Okwangoku, iibheringi eziqengqelekayo ziye zaphuhliswa zaba luhlobo oluphambili loomatshini abaxhasayo, kwaye zisetyenziswa kakhulu nangakumbi.
