Kungani ukusebenza kwe-plastic bearing kungcono kunokusebenza kwe-metal bearing

 

1. Amathemba okuthuthukiswa kwama-bearings epulasitiki

Njengamanje, iningi lamakhasimende kukhona namanje uzimisele ukukhetha i-bearing yensimbi ye- imishini. Phela, lapho ama-bearing epulasitiki engakhiqizwa, ama-bearing ensimbi ayesetshenziswa njalo njengezinto zendabuko. Kodwa kuze kube manje, ukusebenza kwama-bearings epulasitiki kuzoba ngcono futhi kube ngcono esikhathini esizayo.

2.Izinto zokuthwala ipulasitiki kanye izinzuzo

TIzindleko zokukhiqiza zepulasitiki ziphansi kunezamabhereli ensimbi, futhi izinhlobonhlobo zezinto zepulasitiki ziya ngokuya zicebile. futhiesetshenziswa ezimbonini eziningiizinto ezivamile zepulasitikiyi-nylon, i-polytetrafluoroethylene, i-polyethylene kanye ne-PEEK.

I amabheringi epulasitiki is Ukuguquguquka, ukonga kanye nokuhlanzeka. Kunezinhlobo eziningi zezinto ezishibhile ezitholakalayo zezinhlelo zokusebenza ezahlukahlukene. Ama-bearings epulasitiki ngokuvamile enziwa ngama-alloys e-thermoplastic ane-fiber matrix kanye ne-lubricant eqinile, enamandla amahle kakhulu kanye ne-coefficient ephansi yokungqubuzana njalo.

3. Iyini ukusebenza okuhle kwama-bearings epulasitiki? ?

(1) Ukuzigcoba ngokwakho

Ipulasitiki's izici ezingokwemvelo, zithambisa ama-bearings, zinciphisa ukubambezeleka kokuqala futhi zigcine indawo ihlanzekile. Ingxenye encane ye-bearings igqokwa ekuqaleni futhi idlala indima yokugcoba i-bearings, kodwa ushintsho lwe-bearings ngokwalo lunganganakwa. Lokhu kwenza nama-bearings epulasitiki afaneleke kakhulu ekusetshenzisweni kokudla, ngoba i-FDA ivimbela ngokuqinile ukusetshenziswa kwama-lubricants emishinini yokukhiqiza ukudla. Ngaphezu kwalokho, yize uthuli nezinye izinhlayiya zizonamathela ku-lubricant futhi zakhe ungqimba lokungcola, kuma-bearings epulasitiki, noma yiziphi izinhlayiya zizomane zifakwe ku-bearings futhi ngeke zithinte ukusebenza.

(2) Ukusebenza ekushiseni okuphansi nokuphezulu

Amabheringi epulasitiki angasebenza ngokuqhubekayo kunoma yiliphi izinga lokushisa eliphakathi kuka -4° C kanye no-260° C futhi ingamelana namazinga okushisa aphezulu afinyelela ku-600° F. I-bushing yepulasitiki ingaba namandla njenge-bushing yensimbi, kodwa ibhere Udonga luncane, ngokuvamile luyi-0.0468 "- 0.0625" ubukhulu. Izindonga ezincane zinikeza ukushabalalisa okungcono kokushisa, okuholela ekusebenzeni okukhulu kanye nokuguguleka okuncishisiwe. Ngaphezu kwalokho, izindonga ezincane zilula futhi cishe azikwazi ukuguguleka, okwenza zifanelekele ukusetshenziswa ngezinkinga zesisindo.

(3) Ukusebenza kwemvelo

Ngenxa yesisindo esincane sepulasitiki, ama-bearings epulasitiki asebenzisa kahle uphethiloli. Ama-bearings epulasitiki awadingi izembozo ezengeziwe noma izithasiselo ukuze akhiqize imiphumela efanayo nezingxenye zensimbi ezivame ukwenezelwa ngezinto eziyingozi. Ngaphezu kwalokho, ukukhiqizwa kwepulasitiki kudinga uwoyela ongaba ngu-10-15% kuphela uma kuqhathaniswa nenani elifanayo le-aluminium noma insimbi.

(4) Ukumelana okuhle kwamakhemikhali

Ama-bearings epulasitiki avame ukumelana kakhulu namakhemikhali nezinto ezahlukahlukene kune-bearings zensimbi, futhi amelana nokuklwebheka nokuguguleka kwama-bearings ensimbi. Lokhu kusiza ukugcina i-coefficient yawo ephansi yokungqubuzana futhi ahambe kahle ngaphandle kokuphazamiseka okuncane.

(5) Ukuthwala okungenakulungiswa

Khetha ipulasitiki efanele ngokwendawo esetshenziswayo, futhi i-bearing ingamelana nokugqwala ngokuhamba kwesikhathi. Ngemva kokufakwa, i-bearing yepulasitiki ihlala isikhathi eside futhi ayidingi ukushintshwa. Ukugqwala kungabangela ukuba ama-bearing ensimbi aqine endaweni yawo, okwenza kube nzima ukuwasusa ngaphandle kokuwasika. Ama-bearing epulasitiki kulula ukuwasusa.

(6) Intengo ephansi yepulasitiki

Amapulasitiki amaningi ashibhile kunezinsimbi. Ngakho-ke amabheringi epulasitiki kanye nama-bushing epulasitiki kunganciphisa izindleko
