Intshayelelo eneenkcukacha kwiintlobo zeebhearing ezityibilikayo

 

Ibheyari etyibilikayo yindawo apho umngxuma kunye nebheri zidibene nomphezulu. Ngenxa yokudibana komphezulu, inokumelana namandla amakhulu angaphandle, ayishukumi, kwaye inesakhiwo esilula, nto leyo eyenza ukuba isetyenziswe kakhulu. Umzekelo, amalungu ashukumayo engalo yomgubungeli.

 

Iibheringi ezityibilikayoinokwahlulwa ibe ziintlobo ezintathu ngokwendlela amandla asebenza ngayo:

 

1. Iibheringi ezityibilikayo zeRadial

Iibheringi ezityibilikayo ze-radial zinamandla angqamene ne-axis ephakathi. Zinokwahlulwa zibe ziintlobo ezintathu ngokusekelwe kwimo yazo:

 

1) Iibheringi Ezidibeneyo: Iibheringi ezidibeneyo luhlobo oluqhelekileyo lwebheringi edibeneyo yeradial sliding, eqhagamshelwe kwifreyimu ngeebholiti. Imbobo yendlu yebheringi icinezelwe, kwaye kufakwa indebe yeoyile phezulu kwendlu yebheringi. I-bushing inomngxuma wokungena kweoyile, kwaye umphezulu wangaphakathi we-bushing (okanye i-bushing) ufakwe izinto zokunciphisa ukungqubana kwaye unemijelo yeoyile ye-axial yokuthambisa.

 

2) Iibheringi Ezihambelanayo: Ezi bheringi kulula ukuzifaka nokuziqhekeza, kwaye azibizi kakhulu, nto leyo eyenza ukuba zisetyenziswe kakhulu koomatshini. Umzekelo, iibheringi ezikwii-crankshafts zeenjini ezahlukeneyo zokutsha kwangaphakathi.

 

3) I-bearing enamacandelo amane: Ikwabizwa ngokuba yi-bearing enamacandelo amane, isetyenziswa kwiimoto ezinkulu, njengee-shaft bearing eziphambili zeenjini ezingcangcazelayo kunye nezinye izixhobo ezifanayo.

 

Izinto ezisetyenziswa xa kutyibilika iibheringi zentsimbi ephothiweyo kunye nentsimbi ephothiweyo. Ngenxa yobunzima bazo, zidla ngokuguguleka kwijenali, ngoko ke i-bushing idla ngokufakwa phakathi kwe-shaft kunye ne-bearing. Izinto ezisetyenziswa xa kutyibilika olu hlobo lwe-bushing ikakhulu yi-bronze, i-alloy emhlophe, kunye ne-alloy ye-Babbitt.

 

2. Iibheringi zokutyhala ezityibilikayo

Umthwalo we-sliding thrust bearing uhambelana necala le-axial. Ukongeza ekuxhaseni ukujikeleza kweendawo zomatshini, unokuthintela intshukumo ecaleni kwecala le-axial. Unokwahlulwa ube ziintlobo ezine:

 

1) Iibheringi zokutyhala ngeringi: Zahlulwe ngakumbi zibe:

 

(1) Iibheringi zokutyhala ezineringi enye: Njengoko kubonisiwe kuMfanekiso 5(a), ibheringi yeringi. Njengoko kubonisiwe kuMfanekiso 5(b), ibheringi yokutyhala eneringi enye inokumelana nokutyhala okujikelezayo kumacala omabini.

 

(2) Iibheringi zokutyhala ezineendandatho ezininzi: Olu hlobo lwebheringi lunokumelana nokutyhala okujikelezayo kumacala omabini, ngesantya esiphezulu, naphantsi kwemithwalo enzima.

 

2) Iibheringi zePivot: Ezikwaziwa ngokuba ziibheringi zepivot, ziibheringi ze-sliding thrust ezifakwe ekupheleni kweshaft, ngoko ke zibizwa ngokuba ziibheringi ze-base-type thrust. 3) Iibheringi ze-Hydrodynamic Thrust: Iindawo zokungqubana phakathi kweshaft kunye ne-bearing zenziwa zibe ziindawo ezithambekileyo okanye iibhloko ezithambekileyo. Umaleko wefilimu yeoyile ye-hydrodynamic uyenziwa kumphezulu ngamnye othambekileyo okanye ibhloko ethambekileyo, ukuthintela ukudibana phakathi kweshaft kunye ne-bearing.

 

4) Iibheringi zeHydrostatic: Xa umthwalo weyunithi yebheringi umkhulu kakhulu, akunakwenzeka ukuba kusekwe ifilimu yeoyile ukusuka kwindawo emileyo, ngoko ke kufuneka kusetyenziswe iibheringi zehydrostatic. Ulwelo (ioyile) lucinezelwa yipompo kwaye luhanjiswe phakathi kwamacandelo amabini ukuze kugcinwe ukuthambisa ngexesha lokusebenza. Ngenxa yokuba ulwelo lunikezelwa luvela ngaphandle, lukwabizwa ngokuba yibheringi yoxinzelelo lwangaphandle. Ukuba uxinzelelo lweoyile yepompo lutshintshelwa kuxinzelelo lomoya, lubizwa ngokuba yibheringi yomoya yehydrostatic.

 

3. Iibheringi eziKhethekileyo zokutyibilika

 

1) Iibheringi Ezinemingxuma: Zikwaziwa ngokuba ziibheringi ezifakwe ioyile, zenziwe kusetyenziswa i-powder metallurgy. Ngokuqhelekileyo zifanelekile kwiibheringi zeradial ezinomthwalo olula.

 

2) Iibheringi ezingenaoyile: Zinokumelana nokuguguleka okuhle kwaye zifanelekile kwiimashini zokulungisa ukutya ezingenamthwalo ulula kwaye ezingenangcoliseko.
