Iimpawu zesakhiwo seebheringi zethusi

Ukuthwala ubhedu yinxalenye ebalulekileyo esetyenziswa ngokubanzi kwisixhobo somatshini. Isetyenziselwa ikakhulu ukuthwala ukujikeleza kwe-shaft, ukunciphisa ukungqubuzana, ukubonelela nge-lubrication kunye nenkxaso. Ngokuqhelekileyo yenziwe nge-alloy yobhedu (efana ne-aluminium bronze, i-tin bronze, njl.), kunye nokumelana nokunxiba kakuhle, ukumelana nokugqwala kunye nomthamo omkhulu womthwalo. Iimpawu zesakhiwo sokuthwala ubhedu ziquka le miba ilandelayo:

1. Izinto eziphathekayo

Ukuthwala ubhedu ngokuqhelekileyo kwenziwa nge-alloy yobhedu, eziqhelekileyo zezi:

I-Aluminiyam yobhedu: inokumelana nokunxiba kakuhle, ukumelana nokugqwala kunye nokumelana nobushushu obuphezulu, ilungele iimeko zomthwalo ophezulu.

Ibronzi ye-tin: inokumelana nokunxiba kakuhle, ukumelana nokugqwala kunye namandla aqinileyo, ilungele iimeko zomthwalo ophakathi kunye nophezulu.

Ubhedu olukhokelayo: lufanelekile kwisantya esiphantsi, umthwalo onzima kunye nezihlandlo ezinkulu zokungcangcazela, kuba ine-self-lubrication.

2. Umaleko ongagugiyo kunye noyilo lwesakhiwo

Ukuthwala ubhedu ngokuqhelekileyo kubandakanya ulwakhiwo olunemigangatho emininzi, oluhlala lunobunzima obuphezulu obungagugiyo kunye nesiseko esithambileyo:

Umaleko okwaziyo ukunxiba: Lo maleko udla ngokuqulunqwa yingxubevange yobhedu ngokwawo okanye umaleko womphezulu onezinto ezidibanisayo, ezinokumelana nokunxiba okuqinileyo kunye nokumelana nokugqwala.

Umaleko we-matrix: I-matrix yokuthwala ubhedu yi-alloy yobhedu, eneplastiki elungileyo kunye ne-coefficient ephantsi yokukhuhlana.

3. Uyilo lwegroove yokuthambisa

Umphezulu wokuthwala ubhedu uhlala uyilwe ngeegrooves zokuthambisa (ezikwabizwa ngokuba zii-oil grooves okanye i-oyile channels) zokugcina nokusasaza ioyile yokuthambisa. Uyilo lwale grooves lunokunciphisa ngokufanelekileyo ukungqubana, ukunciphisa ubushushu, kunye nokuphucula isiphumo sokuthambisa, ukwandisa ubomi benkonzo yokuthwala.

4. Uyilo lokulwa nokuhlutha

Ukuthwala kudla ngokuyilwa kunye "ne-gap" ethile yokuqinisekisa ukuba kukho indawo eyaneleyo ngexesha lofakelo ukwenzela ukuba i-oyile yokuthambisa ikwazi ukungena phakathi kwe-bearing kunye ne-shaft ukwenza ifilimu yeoli yokuthintela ukudibanisa ngokuthe ngqo kwesinyithi, ngaloo ndlela kuncitshiswe ukunxiba kunye nokuhlutha.

5. Umthamo wokuthwala umthwalo kunye ne-elasticity

Izinto eziphathekayo zobhedu zinomthamo omhle wokuthwala kwaye zikwazi ukugcina i-elasticity eyaneleyo kunye nokuqina xa usebenza phantsi komthwalo ophezulu, obaluleke kakhulu kumthwalo we-shafts enkulu.

6. Umthamo wokutshatyalaliswa kobushushu

Izinto zobhedu zine-conductivity efanelekileyo ye-thermal, enceda ukuthwala ukukhupha ngokufanelekileyo ukushisa kunye nokugcina ubushushu obufanelekileyo xa usebenza ngesantya esiphezulu ukukhusela umonakalo kwi-bearing ngenxa yokushisa.

7. Ukumelana nokubola

I-alloys ye-Copper inokumelana ne-corrosion yendalo, ngokukodwa kumacandelo omatshini asetyenziswa emanzini okanye kwindawo yeekhemikhali. Ngenxa yokuzinza kweekhemikhali zobhedu, iibheringi ziyakwazi ukumelana neendawo zokusebenza ezinzima.

8. Ukuzithambisa (phantsi koyilo oluthile olukhethekileyo)

Ezinye iibheringi ze-alloy ze-copper nazo zenzelwe ukuba zi-self-lubricating, ngokuqulunqwa kwezinto ezikhethekileyo okanye ukongezwa kwamancinci amancinci okuthambisa ukuphumeza iziphumo zexesha elide zokuthambisa kunye nokunciphisa ukuxhomekeka kwii-lubricant zangaphandle.

Isishwankathelo

Iimpawu zesakhiwo seebheringi zethusi zibonakaliswa ngokukodwa kwizinto zabo (i-alloy yobhedu), ukuxhathisa ukunxiba, ukuthambisa okulungileyo, ukuyila okufanelekileyo kokushisa ubushushu kunye nokumelana nokugqwala. Ngolu yilo, inokunciphisa ukungqubana, ukwandisa ubomi benkonzo kunye nokubonelela ngokusebenza okuzinzileyo kwizixhobo ezahlukeneyo zoshishino.
