Iintlobo zeebheringi ezicacileyo

 

Umsantsa phakathi komngxuma kunyeibhereyithaidibana nomphezulu, obizwa ngokuba yi-plain bearing. Isetyenziswa kakhulu kuba yindlela edibana ngayo nomphezulu enokumelana namandla amakhulu angaphandle, ayitshisi, kwaye inesakhiwo esilula. Umzekelo, iindawo ezishukumayo ze-Excavator's Monster Hand.

 

Iibheringi ezityibilikayoinokwahlulwa ibe ziintlobo ezintathu ngokwendlela amandla asebenza ngayo, ezizezi:

 

1. Ibhereyitha yokutyibilika ye-radial

Icala lamandla leebheringi ezicacileyo ze-radial lithe nkqo kwi-axis ephakathi, enokwahlulwa ibe ziintlobo ezintathu ngokwemo:

 

1) I-Integral bearing: I-Integral sliding bearing yi-integral radial sliding bearing eqhelekileyo, eqhagamshelwe kwisakhelo ngeebholiti. Uxinzelelo lwangaphakathi lwe-bearing seat bore, indebe yeoyile ifakwe phezulu kwendlu ye-bearing, umngxuma wokungena kweoyile ukwisilingi se-shaft, kwaye umphezulu wangaphakathi uzaliswe yi-bearing (okanye i-shaft sleeve) eyenziwe ngezinto ezichasene nokungqubana ukuvula i-axial oil groove ukuze kusasazwe i-lubricating oil lubricating.

 

2) Ukulinganisa iibheringi: Olu hlobo lweebheringi kulula kakhulu ukulifaka nokuliqhaqha, kwaye ixabiso liphantsi, kwaye lisetyenziswa kakhulu ngoomatshini. Umzekelo, iibheringi kwii-cranks zeentlobo ezahlukeneyo zeenjini zomlilo zangaphakathi

 

3) Ibheriya enamacandelo amane: eyaziwa ngokuba yibheriya enamacandelo amane, esetyenziswa kwiimoto ezinkulu, ezifana neenjini zokungcangcazela, iinjini zokungcangcazela kunye nezinye iibheriya ze-spindle.

 

Izinto ezisetyenziswa kwiibheringi ezicacileyo ikakhulu ziintsimbi eziphosiweyo kunye nentsimbi ephosiweyo. Ngenxa yobunzima bokuthungwa kwayo, kulula ukubangela ukuguguleka kwejenali, ngoko ke i-bushing idla ngokongeza phakathi kwe-shaft kunye ne-bearing. Izinto ezisetyenziswa kule bushing ikakhulu ziibronze, i-alloy emhlophe kunye ne-barbit alloy.

 

2. Ibheyari yokutyhala etyibilikayo

 

Umthwalo we-plain thrust bearing uhambelana nolwalathiso lwe-axial, olungagcini nje ngokuxhasa ukujikeleza kwendlela, kodwa lukwathintela intshukumo ecaleni kwe-axis. Ingahlulwa ibe ziintlobo ezine:

 

1) Ibheri yokutyhala ngeringi: yahlulwe yaba:

 

(1) I-single-ring thrust bearing: I-single-ring thrust bearing, enokumelana ne-axial thrust kumacala omabini.

 

(2) I-Multi-ring thrust bearing: Olu hlobo lwe-shaft lunokuthwala i-axial thrust kuzo zombini iindlela, ngesantya esiphezulu nangomthwalo onzima.

 

2) I-Class bearing: ekwaziwa ngokuba yi-pivot bearing, yi-sliding thrust bearing efakwe ekupheleni kwe-shaft, ngoko ke ikwabizwa ngokuba yi-base column thrust bearing.

 

3) I-Hydrodynamic lubrication thrust bearing: umphezulu wokungqubana phakathi kwe-shaft kunye ne-bearing wenziwa ube ngumphezulu othambekileyo okanye ibhloko ethambekileyo. Umaleko we-hydrodynamic oil wenziwa kumphezulu ngamnye othambekileyo okanye ibhloko ethambekileyo ukuze i-shaft ingadibani ne-bearing.

 

4) I-Hydrostatic bearing: Xa umthwalo weyunithi ye-bearing umkhulu kakhulu, akunakwenzeka ukuseka ifilimu yeoyile ngokuqala ngokunganyakazi, ngoko ke i-hydrostatic bearing kufuneka isetyenziswe. Ulwelo (ioyile) lucinezelwa yipompo kwaye luthunyelwa phakathi kwamacandelo amabini ukugcina ukuthambisa ngexesha lokusebenza. Ngenxa yokuba ulwelo lubonelelwa lihlabathi langaphandle, lukwabizwa ngokuba yi-external pressure bearing. Ukuba uxinzelelo lweoyile yepompo lutshintshelwa kuxinzelelo lomoya, lubizwa ngokuba yi-hydrostatic air bearing.

 

3. Iibheringi ezikhethekileyo zokutyibilika

 

1) I-Porous bearing: ekwaziwa ngokuba yi-oil-inpregnated bearing, iqhekeka ngendlela yokuqhekeka kwe-powder metallurgy. Ifanelekile ngokubanzi kwii-radial bearings ezinemithwalo elula.

 

2)Iibheringi ezingenawo amafutha: zinokumelana nokuguguleka okugqwesileyo, zilungele oomatshini bokulungisa ukutya abalula kunye nabangcolisiyo, njengeebheringi zeNelong.
