Kutheni ukusebenza kweplastiki yeplastiki kungcono kuneyokuthwala isinyithi

 

1. Ithemba lophuhliso lweebheringi zeplastiki

Okwangoku, uninzi lwabathengi zi nangoku ukulungele ukukhetha intsimbi yentsimbi izixhobo. Ngapha koko, xa iibheringi zeplastiki zingaveliswanga, iintsimbi zentsimbi zazisoloko zisetyenziswa njengezinto zemveli. Kodwa ukuza kuthi ga ngoku, ukusebenza kweebheringi zeplastiki kuya kuba ngcono kwaye kube ngcono kwixesha elizayo.

2.Izinto zokuthwala iplastiki kunye iingenelo

Tiindleko zokuvelisa zeplastiki ziphantsi kuneebheringi zentsimbi, kwaye iintlobo ngeentlobo zezinto zeplastiki ziya zisiba zizityebi kwayeisetyenziswa kumashishini amaninzi,izinto eziqhelekileyo zeplastikiyinayiloni, i-polytetrafluoroethylene, i-polyethylene kunye ne-PEEK.

I iibheringi zeplastiki is ukuguquguquka, uqoqosho kunye nococeko . Zininzi izinto ezixabisa ixabiso eliphantsi ezikhoyo kwizicelo ezahlukeneyo. Iibheringi zePlastiki zihlala zenziwe ngee-alloys ze-thermoplastic ezinefiber matrix kunye ne-lubricant eqinileyo, enamandla abalaseleyo kunye ne-coefficient ephantsi yokhuhlane.

3. Yintoni umsebenzi omhle weebheringi zeplastiki ?

(1) Ukuzithambisa

Iplastiki's iimpawu zendalo, ithambisa iibheringi, inciphisa ukulibaziseka kokuqalisa kwaye igcina indawo icocekile. Incinci encinci yokuthwala igqoke ekuqaleni kwaye idlala indima yokuthambisa i-bearing, kodwa utshintsho lwe-bearing ngokwayo lunokungahoywa. Oku kwenza ukuba iibheringi zeplastiki zilunge ngakumbi kwizicelo zokutya, kuba i-FDA ikuthintela ngokungqongqo ukusetyenziswa kwezithambiso koomatshini bokuvelisa ukutya. Ukongezelela, nangona uthuli kunye nezinye iinqununu ziya kubambelela kwi-lubricant kwaye zenze uluhlu lokungcola, kwiibherethi zeplastiki, naziphi na iinqununu ziya kufakwa nje kwi-bearing kwaye aziyi kuchaphazela ukusebenza.

(2) Ukusebenza kwiqondo lokushisa eliphantsi kunye eliphezulu

Iibheringi zeplastiki zinokusebenza ngokuqhubekayo kulo naliphi na iqondo lobushushu eliphakathi kwe -4° C kunye ne-260° C kwaye inokumelana nobushushu obuphezulu ukuya kuthi ga kwi-600° F. I-plastic bushing ingaba namandla njengentsimbi yentsimbi, kodwa i ukuzala udonga lubhityile, ludla ngokuba ngu-0.0468 "- 0.0625" ubukhulu. Iindonga ezincinci zibonelela ngokutshatyalaliswa kobushushu obungcono, okubangelwa uluhlu olukhulu lokusebenza kunye nokunciphisa ukugqoka. Ukongeza, iindonga ezibhityileyo zikhaphukhaphu kwaye azinakwenzeka ukuba zikhubazeke, zizenze zilungele izicelo ezineengxaki zobunzima.

(3) Ukusebenza kwendalo

Ngenxa yobunzima obulula beplastiki, iibheringi zeplastiki ziwonga kakhulu amafutha. Iiplastiki zeplastiki azidingi iingubo ezongezelelweyo okanye izongezo zokuvelisa iziphumo ezifanayo njengeengxenye zetsimbi eziqhelekileyo zongezwa ngezinto eziyingozi. Ukongezelela, ukuveliswa kweplastiki kufuna kuphela i-oyile ye-10-15% xa kuthelekiswa nomlinganiselo ofanayo we-aluminium okanye intsimbi.

(4) Ukumelana neekhemikhali ezilungileyo

Iibheringi zePlastiki zihlala zixhathisa ngakumbi kwiikhemikhali ezahlukeneyo kunye nezinto kuneebheringi zetsimbi, kwaye zixhathisa imikrwelo kunye nokunxiba kweebheringi zetsimbi. Oku kunceda ukugcina i-coefficient ephantsi ye-friction kunye nokuhamba kakuhle kunye nokuphazamiseka okuncinci.

(5) Ukugcinwa ngokukhululekileyo

Khetha iplastiki echanekileyo ngokwendawo yokusetyenziswa, kwaye ukuthwala kunokumelana nokubola ngokuhamba kwexesha. Emva kokufakela, ukuthwala iplastiki kunobomi obude benkonzo kwaye ayifuni ukutshintshwa. Ukonakala kunokubangela ukuba iibheringi zentsimbi zibe ngumkhenkce endaweni, nto leyo eyenza ukuba kube nzima ukuyisusa ngaphandle kokuyinqumla. Iibheringi zeplastiki kulula ukuzisusa.

(6) Ixabiso eliphantsi leeplastiki

Iiplastiki ezininzi zinexabiso eliphantsi kuneentsimbi. Ngoko iibheringi zeplastiki kunye namatyholo eplastiki anokunciphisa iindleko
