Kutheni ukusebenza kwe-plastic bearing kungcono kune-metal bearing

 

1. Uphuhliso olunokwenzeka lweebheringi zeplastiki

Okwangoku, uninzi lwabathengi zi nangoku uzimisele ukukhetha ibheyitha yesinyithi izixhobo. Kaloku, xa iibheringi zeplastiki zingenziwanga, iibheringi zesinyithi zazisoloko zisetyenziswa njengezinto zemveli. Kodwa ukuza kuthi ga ngoku, ukusebenza kweebheringi zeplastiki kuya kuba ngcono nangakumbi kwixesha elizayo.

2.Izixhobo zokuthwala iplastiki kunye iingenelo

TIindleko zemveliso yeplastiki ziphantsi kunezo zeebheringi zesinyithi, kwaye iintlobo ngeentlobo zezinto zeplastiki ziya zityeba ngakumbi. kwayeisetyenziswa kumashishini amaninzi, izinto zeplastiki eziqhelekileyozii-nylon, i-polytetrafluoroethylene, i-polyethylene kunye ne-PEEK.

I iibheringi zeplastiki is Ukuguquguquka, ukonga kunye nococeko. Kukho izinto ezininzi ezingabizi kakhulu ezifumanekayo kwiindlela ezahlukeneyo zokusetyenziswa. Iibheringi zeplastiki zihlala zenziwe ngee-alloys ze-thermoplastic ezine-fiber matrix kunye ne-lubricant eqinileyo, ezinamandla amahle kunye ne-coefficient ephantsi yokungqubana rhoqo.

3. Yintoni ukusebenza kakuhle kweebheringi zeplastiki ?

(1) Ukuzithambisa ngokwakho

Iplastiki's iimpawu zayo ezisisiseko, ithambisa iibheringi, inciphisa ukulibaziseka kokuqala kwaye igcina indawo icocekile. Inxalenye encinci yebheringi inxitywa ekuqaleni kwaye idlala indima yokuthambisa ibheringi, kodwa utshintsho lwebheringi ngokwalo lunokunganakwa. Oku kwenza iibheringi zeplastiki zifaneleke ngakumbi kwizicelo zokutya, kuba i-FDA ithintela ngokungqongqo ukusetyenziswa kwee-lubricants kumatshini wokuvelisa ukutya. Ukongeza, nangona uthuli kunye nezinye ii-particles ziya kunamathela kwi-lubricant kwaye zenze umaleko wokungcola, kwiibheringi zeplastiki, naziphi na ii-particles ziya kufakwa kwi-bearing kwaye aziyi kuchaphazela ukusebenza.

(2) Ukusebenza kubushushu obuphantsi nobuphezulu

Iibheringi zeplastiki zinokusebenza ngokuqhubekayo nakweyiphi na iqondo lobushushu eliphakathi kwe -4° C kunye ne-260° C kwaye inokumelana namaqondo obushushu aphezulu ukuya kuthi ga kwi-600° F. I-bushing yeplastiki inokuba namandla njenge-bushing yesinyithi, kodwa ibhereyitha Udonga lubhityile, ludla ngokuba nobukhulu obuyi-0.0468 "- 0.0625". Iindonga ezincinci zibonelela ngokusasazwa kobushushu okungcono, nto leyo ebangela ukuba kusebenze ixesha elide kwaye kunciphe ukuguguleka. Ukongeza, iindonga ezincinci zikhaphukhaphu kwaye azinakwenzeka ukuba ziguquguquke, nto leyo eyenza ukuba zifaneleke ukusetyenziswa ngabantu abaneengxaki zobunzima.

(3) Ukusebenza kokusingqongileyo

Ngenxa yobunzima obulula beplastiki, iibheringi zeplastiki zisebenza kakuhle kumafutha. Iibheringi zeplastiki azidingi zigqubuthelo ezongezelelweyo okanye izongezo ukuvelisa iziphumo ezifanayo nezeendawo zesinyithi ezihlala zincediswa zizinto eziyingozi. Ukongeza, imveliso yeplastiki ifuna ioyile eyi-10-15% kuphela xa kuthelekiswa nomlinganiselo ofanayo we-aluminium okanye intsimbi.

(4) Ukumelana kakuhle kweekhemikhali

Iibheringi zeplastiki zihlala zixhathisa ngakumbi kwiikhemikhali ezahlukeneyo kunye nezinto kuneebheringi zesinyithi, kwaye ziyamelana nemikrwelo kunye nokuguguleka kweebheringi zesinyithi. Oku kunceda ukugcina i-coefficient yazo ephantsi yokungqubana kwaye zihambe kakuhle ngaphandle kokuphazamiseka okukhulu.

(5) Ukulungiswa kwebheyari ekhululekileyo

Khetha iplastiki echanekileyo ngokwendawo esetyenziswa kuyo, kwaye i-bearing inokumelana nokugqwala ngokuhamba kwexesha. Emva kokufakwa, i-bearing yeplastiki inobomi obude benkonzo kwaye ayifuni ukutshintshwa. Ukugqwala kunokubangela ukuba ii-bearing zesinyithi ziqine endaweni yazo, nto leyo eyenza kube nzima ukuzisusa ngaphandle kokuzinqumla. Ii-bearing zeplastiki kulula ukuzisusa.

(6) Ixabiso eliphantsi leeplastiki

Iiplastiki ezininzi zibiza kancinci kuneentsimbi. Ngoko ke iibheringi zeplastiki kunye neebhushi zeplastiki zinokunciphisa iindleko
