Kodi kompositi ndi chiyani

Zinyalala zomwe zimapangidwa ndi zigawo zosiyanasiyana (zitsulo, mapulasitiki, zopangira mafuta olimba) zimatchedwa zitsulo zophatikizika, zomwe zimakhala zomveka bwino, ndi zitsulo zamagulu, zomwe zimatchedwanso bushings, pads kapena sleeve bearings, nthawi zambiri zimakhala za cylindrical ndipo zilibe zigawo zosuntha.

 

Kukonzekera kokhazikika kumaphatikizapo ma cylindrical bearings for radial loads, flange bearings for radial and light axial loads, spacers and turn-over gaskets for heavy axial loads, and sliding plates of different shapes. Mapangidwe achikhalidwe amapezekanso, kuphatikiza mawonekedwe apadera, mawonekedwe (sump, mabowo, notch, ma tabo, ndi zina) ndi makulidwe.

 

Mapiritsi a kompositiamagwiritsidwa ntchito poterera, kuzungulira, kuzungulira kapena kusuntha. Zovala zowoneka bwino zimagwiritsidwa ntchito ngati ma bearings osavuta, okhala ndi gaskets, ndi mbale zovala. Malo otsetsereka nthawi zambiri amakhala athyathyathya, koma amathanso kukhala acylindrical ndipo nthawi zonse amayenda molunjika, osati mozungulira. Ntchito zozungulira zimaphatikizapo nkhope zozungulira komanso njira imodzi kapena ziwiri zoyendera. Ntchito zoyenda mozungulira komanso zobwerezabwereza zimaphatikizapo malo athyathyathya kapena ma cylindrical omwe amayenda mbali zonse ziwiri.

 

Zomangamanga zokhala ndi zophatikiza zimatha kukhala zolimba kapena zogawanika (zokulungidwa) kuti zikhale zosavuta. Kufananiza mawonekedwe ndi ntchito ndikofunikira. Katundu wokwera amafunikira ma mayendedwe okhala ndi malo olumikizana nawo komanso kunyamula katundu wambiri. Zonyamula mafuta olimba amapangidwa kuti azigwira ntchito kutentha kwambiri kuposa mafuta opaka mafuta ndi mafuta opaka mafuta. Ntchito zotentha kwambiri zimafunikira njira zapadera zokometsera kuti muchepetse kutentha komanso kukangana.

 

Mapiritsi a kompositiamapangidwa m'magulu osiyanasiyana. Kusankhidwa kwa mankhwala kumadalira momwe ntchito ikugwiritsidwira ntchito komanso zofunikira zogwirira ntchito.

 

Mitundu ya zida zonyamula zotsika kwambiri

 

Zitsulo zopangidwa ndi zitsulo zimakhala ndi zitsulo zothandizira (nthawi zambiri zitsulo kapena mkuwa) zomwe porous copper interlayer imayikidwa, imayikidwa ndi PTFE ndi zowonjezera kuti zipeze malo othamanga ndi anti-friction ndi katundu wovala kwambiri. mayendedwe awa akhoza opareshoni youma kapena kunja mafuta.

 

Mapiritsi a kompositi amathanso kupangidwa ndi mapulasitiki a uinjiniya, omwe ali ndi kukana kwamphamvu kwambiri komanso kutsika kwamphamvu kwamphamvu, ndipo amagwiritsidwa ntchito kwambiri pakuwombana kowuma komanso kupangira mafuta. Jekeseni wowumbidwa, womwe ukhoza kupangidwa pafupifupi mawonekedwe aliwonse ndipo umapangidwa kuchokera ku utomoni wosiyanasiyana wosakanikirana ndi ulusi wolimbitsa komanso mafuta olimba. Ma faniwa ali ndi kukhazikika kwabwino kwambiri, kutsika kokwanira kwa kukangana ndi matenthedwe abwino.

 

Fiber-reinforced composite bearings ndi mtundu wina wa zitsulo zophatikizika, zomwe zimapangidwa ndi filament-bala, fiberglass-impregnated, epoxy wear-resistant low-friction linings ndi kumbuyo kosiyanasiyana. Kamangidwe kameneka kamapangitsa kuti chigawocho chizitha kupirira katundu wokhazikika komanso wosasunthika, ndipo kusakhazikika kwa zinthuzo kumapangitsa kukhala koyenera kugwiritsidwa ntchito m'malo owononga.

 

Monometal, bimetal, ndi sintered copper kompositi bearings amapangidwa kuti azigwiritsidwa ntchito pamtunda ndi pansi pa madzi, komwe amayenda pang'onopang'ono pansi pa katundu wambiri. Mafuta opangidwa ndi mkuwa olimba omwe ali ndi mkuwa amapereka ntchito yosamalidwa bwino muzotentha kwambiri, pamene ma mono- ndi bimetal-based bearings amapangidwa kuti azipaka mafuta.

 

Kusiyana pakatima fani a kompositindikugudubuza ndi singano wodzigudubuza fani

 

Pali kusiyana kwakukulu pakati pa ma fani a kompositi ndi ogudubuza, kotero iwo sasintha.

 

1. Mapiritsi ogubuduza, chifukwa cha mapangidwe awo amitundu yambiri, mawonekedwe olondola komanso kuyika kolondola, nthawi zambiri amakhala okwera mtengo kwambiri kuposa mayendedwe ophatikizika.

2. Mapiritsi odzigudubuza ndi abwino kwambiri kwa mapulogalamu omwe amafunikira malo enieni a shaft ndi / kapena kukangana kochepa kwambiri.

3. Mapiritsi ophatikizika, chifukwa cha malo awo akuluakulu okhudzana ndi kugwirizanitsa ndi kusinthasintha, amatha kupereka mphamvu zowonjezera zonyamula katundu ndi kukana katundu wokhudzidwa kwambiri ndi katundu wokhazikika pamapeto.

4. Mapiritsi ophatikizika amalipira kusalinganika bwino kuposa ma bereti ena ogubuduza kuti achepetse mphamvu ya katundu wokhazikika pamapeto.

5. Kuphatikizika kophatikizana kumatengera kapangidwe kakang'ono kakang'ono kakang'ono, komwe kumatha kuchepetsa kukula kwa chipolopolo, kusunga malo ndi kulemera kwakukulu.

6. Kuphatikizika kophatikizana kumatsutsana kwambiri ndi kayendedwe kobwerezabwereza, komwe kungathe kutalikitsa moyo wa kubereka.

7. Kuphatikizika kophatikizana sikudzawonongeka ndi kuvala komwe kumachitika chifukwa cha kutsetsereka kwa zinthu zogubuduza pothamanga kwambiri komanso kutsika kwambiri, ndipo kumakhala ndi ntchito yabwino kwambiri yonyowa.

8. Poyerekeza ndi mayendedwe ogubuduza, mayendedwe ophatikizika alibe magawo osuntha mkati, kotero amathamanga mwakachetechete ndipo alibe malire pa liwiro pansi pa dongosolo lopaka mafuta bwino.

9. Kuyika kwa ma bearings ophatikizika ndikosavuta, chipolopolo chokhacho chimafunikira, ndipo sichingawononge zidazo poyerekeza ndi mayendedwe ogubuduza.

.

11. Kuphatikizika kophatikizana kumatha kuyimitsidwa popanda mtengo wamafuta owonjezera, mafuta ndi nthawi yopumira pazida pakukonza.

12. Kunyamula kophatikizana kumatha kuyendetsedwa mouma pansi pa kutentha kwakukulu ndi zonyansa.
