Iimeko Zokusebenza Ezihambelana ngokuchanekileyo: Amaqhinga Aphambili kunye neSikhokelo Esisebenzayo Sokukhetha Iibhereyi Ezityibilikayo

 

Kwiinkqubo zothumelo loomatshini, ukutyibilika kwe-radialiibheringizizinto ezibalulekileyo ezixhasa imingxunya ejikelezayo. Ukuqonda kokukhethwa kwazo kuchaphazela ngokuthe ngqo uzinzo kunye nobomi bezixhobo. Xa sijongene neemeko ezahlukeneyo zokusebenza, singenza njani izigqibo ezinolwazi ukuze siphephe ukubulala kakhulu okanye ukubulala kakhulu?

 

Eli nqaku libonelela ngendlela yokukhetha ecwangcisiweyo ngokusekelwe kwiinkalo ezintathu: uhlobo lolwakhiwo, ukuhambelana kweeparameter zokusebenza, kunye neempawu zezinto.

 

1. Ukwahlulahlula ngokweSakhiwo ukuze kuhambelane neemfuno zoFakelo kunye noLondolozo

 

Ukutyibilikaiibheringizihlulwe kakhulu zibe ziindidi ezintathu:

 

Idibeneyo: Incinci kwaye ingabizi kakhulu, ifanelekile kwimithwalo elula, isantya esiphantsi, kunye nokusetyenziswa okufuna ukuhlanganiswa nokuqhaqhwa rhoqo, njengeemoto ezincinci kunye nezixhobo zasekhaya.

 

Ukwahlulahlula: Kulula ukuyifaka nokugcina indawo eyi-axial, esetyenziswa kakhulu kwizixhobo eziphakathi ukuya kwezinkulu, ezifana neebhokisi zegiya kunye neecompressor, ezifuna ukulungiswa rhoqo.

 

Ukuzilungelelanisa: Ixhotyiswe ngomsebenzi wokuzilungelelanisa ngokuzenzekelayo, ilungisa ukuphambuka kweshaft okanye ukuphambuka kokufakwa. Ifanelekile kwiishaft ezinde okanye izakhiwo ezibuthathaka kwaye ifumaneka rhoqo kwiimashini ezinzima nakwiinkqubo zokuqhuba zaselwandle.

 

2. Sebenzisa iigophe ezibonisa iimpawu ukuze uchonge ngokukhawulezaibhereyithaiintlobo

 

Kwimisebenzi yobunjineli, ijika elibonisa ukukhetha iibheringi lidla ngokusetyenziswa xa kujongwa kwangaphambili. Le tshati isebenzisa isantya sejenali njenge-axis ethe tye kunye nomthwalo ngokweyunithi nganye eqikelelweyo njengendawo ethe nkqo ukwahlulahlula uluhlu olufanelekileyo lweebheringi ezahlukeneyo. Umzekelo, kwisantya esiphantsi kunye nomthwalo onzima, iibheringi ezithanjiswe ngolwelo ziyathandwa; kwisantya esiphakathi kunye nomthwalo ophakathi, iibheringi eziqhekekileyo ezine-lubrication engaphelelanga lukhetho oluqhelekileyo; kwisantya esiphezulu kunye nomthwalo olula, iibheringi ezizithambisayo okanye zeplastiki zingasetyenziselwa ukunciphisa ukungqubana kunye nokunyuka kwamaqondo obushushu. Ngokujonga itafile (njengeetshathi zokukhetha kwimigangatho yoshishino), abayili banokususa ngokukhawuleza iintlobo ezingafanelekanga, bephucula ukusebenza kakuhle kokukhetha.

 

3. Uthelekiso lwentsebenzo yezinto ezibonakalayo lumisela ukuthembeka kokusebenza

 

YahlukileibhereyithaIzixhobo zifanelekile kwiindawo ezahlukeneyo zokusebenza: Iibheringi ze-powder metallurgy: Ziyazithambisa kwaye zifanelekile kwiindawo ezingena-oyile okanye ezine-oyile ephantsi, kodwa zinokumelana okubuthathaka kwaye zisetyenziswa kakhulu kwizixhobo ezinomthwalo omncinci, ezihlala ixesha elide. Iibheringi zeplastiki (ezifana neebheringi ezisekwe kwi-POM kunye ne-PTFE): Azinawo umhlwa, azinangxolo ingako, kwaye azidingi lubrication, kodwa zinozinzo olubi kubushushu kwaye zifanelekile kwiindawo ezifumileyo nezicocekileyo, okanye ekucutshungulweni kokutya. Iibheringi ezine-Babbitt: Zinika amandla omthwalo aqinileyo kunye nokuthobela okugqwesileyo, okwenza zibe lolona khetho lukhethwayo kwizixhobo ezinomthwalo onzima, ezikhawulezayo. Nangona kunjalo, zibiza kakhulu kwaye zifuna inkqubo yokugcoba.

 

UkutyibilikaibhereyithaUkukhetha akumiselwa yiparameter enye; lurhwebo olupheleleyo phakathi kohlobo lwesakhiwo, iimeko zokusebenza, kunye neempawu zezinto. Abayili bayacetyiswa ukuba basebenzise iitshathi zokukhetha ukwenza uvavanyo lokuqala olusekelwe kwisantya esithile, imithwalo, imida yendawo, kunye nemijikelo yokugcinwa. Emva koko, kufuneka bathelekise iimpawu zezinto ukuze ekugqibeleni bafumane isisombululo esifanelekileyo. Kwabaqalayo, ukuqonda le nkqubo icwangcisiweyo kunokuphucula kakhulu ukusebenza kakuhle kunye nokuthembeka koyilo.
