Kodi chogwirira chophatikizana ndi chiyani?

Mabearing omwe amapangidwa ndi zigawo zosiyanasiyana (zitsulo, mapulasitiki, zinthu zolimba zopaka mafuta) amatchedwa mabearing a composite, omwe ndi mabearing osavuta, ndipo mabearing a composite, omwe amadziwikanso kuti bushings, pads kapena sleeve bearing, nthawi zambiri amakhala ozungulira ndipo alibe ziwalo zosuntha.

 

Makonzedwe wamba akuphatikizapo ma bearing a cylindrical a radial loads, ma flange bearing a radial ndi axial loads opepuka, ma spacers ndi ma turn-over gaskets a ma axial loads olemera, ndi ma sliding plates amitundu yosiyanasiyana. Mapangidwe apadera amapezekanso, kuphatikizapo mawonekedwe apadera, mawonekedwe (sump, mabowo, notches, tabs, ndi zina zotero) ndi kukula kwake.

 

Ma bereji ophatikizikaamagwiritsidwa ntchito poyenda mozungulira, mozungulira, mozungulira kapena mozungulira. Ntchito zosavuta nthawi zambiri zimagwiritsidwa ntchito ngati ma bearing osavuta, ma bearing gasket, ndi mbale zosweka. Malo otsetsereka nthawi zambiri amakhala athyathyathya, koma amathanso kukhala ozungulira ndipo nthawi zonse amayenda molunjika, osati mozungulira. Ntchito zozungulira zimaphatikizapo nkhope zozungulira ndi njira imodzi kapena ziwiri zoyendera. Ntchito zozungulira ndi zozungulira zimaphatikizapo malo athyathyathya kapena ozungulira omwe amayenda mbali zonse ziwiri.

 

Kapangidwe ka bere lopangidwa ndi composite kangakhale kolimba kapena kogawanika (bere lopindika) kuti kukhazikike kosavuta. Kugwirizanitsa bere ndi ntchito ndikofunikira kwambiri. Katundu wambiri amafunika mabere okhala ndi malo olumikizirana komanso mphamvu zambiri zonyamulira katundu. Mabere opaka mafuta olimba amapangidwa kuti azigwira ntchito kutentha kwambiri kuposa mafuta opaka mafuta ndi mabere opaka mafuta. Kugwiritsa ntchito kutentha kwambiri kumafuna njira zapadera zopaka mafuta kuti kuchepetse kukwera kwa kutentha ndi kukangana.

 

Ma bereji ophatikizikaamapangidwa m'njira zosiyanasiyana. Kusankha chinthu kumadalira momwe chimagwirira ntchito komanso zofunikira pakugwira ntchito.

 

Mitundu ya zipangizo zonyamula katundu zotsika mtengo

 

Maberiyani achitsulo opangidwa ndi zitsulo amakhala ndi kumbuyo kwachitsulo (nthawi zambiri chitsulo kapena mkuwa) komwe gawo la mkuwa lokhala ndi mapokoso limapakidwa, lodzazidwa ndi PTFE ndi zowonjezera kuti lipange malo othamanga okhala ndi mphamvu zotsutsana ndi kukangana komanso kuwononga kwambiri. Maberiyani awa amatha kugwiritsidwa ntchito owuma kapena opaka mafuta akunja.

 

Maberiyani opangidwa ndi zinthu zosiyanasiyana angapangidwenso ndi mapulasitiki aukadaulo, omwe ali ndi mphamvu zotha kusweka bwino komanso mphamvu zochepa zothina, ndipo amagwiritsidwa ntchito kwambiri pa ntchito youma komanso mafuta odzola. Amapangidwa ndi jekeseni, omwe angapangidwe kukhala mawonekedwe aliwonse ndipo amapangidwa kuchokera ku mitundu yosiyanasiyana ya utomoni wosakaniza ndi ulusi wolimbitsa ndi mafuta olimba. Maberiyani awa ali ndi kukhazikika kwabwino kwambiri, kusinthasintha kochepa komanso kutentha kwabwino.

 

Ma bearing a composite olimbikitsidwa ndi ulusi ndi mtundu wina wa ma bearing a composite, omwe amapangidwa ndi ma filament-wound, fiberglass-impregnated, epoxy wear-resistant low-friction bearing linings ndi ma backbacks osiyanasiyana. Kapangidwe kameneka kamalola bearing kupirira katundu wosasunthika komanso wosinthasintha, ndipo kusagwira bwino ntchito kwa chinthucho kumapangitsa kuti chikhale choyenera kugwiritsidwa ntchito m'malo owononga.

 

Mabearing a mkuwa opangidwa ndi monometal, bimetal, ndi sintered copper composite amapangidwira kugwiritsidwa ntchito m'mafakitale apansi pa nthaka ndi pansi pa madzi, komwe amayenda pang'onopang'ono pansi pa katundu wambiri. Mabearing a mkuwa olimba odzazidwa ndi mafuta amapereka magwiridwe antchito osasamalira m'mafakitale otentha kwambiri, pomwe mabearing a mono- ndi bimetal amapangidwira kugwiritsa ntchito mafuta.

 

Kusiyana pakati pamabearing ophatikizikandimabearing ozungulira ndi singano

 

Pali kusiyana kwakukulu pakati pa mabearings a composite ndi rolling, kotero sasinthasintha.

 

1. Ma rolling bearing, chifukwa cha kapangidwe kake kovuta ka zinthu zambiri, kapangidwe kolondola komanso kuyika kolondola, nthawi zambiri amakhala okwera mtengo kwambiri kuposa ma composite bearing.

2. Ma rolling bearing ndi oyenera kwambiri kugwiritsa ntchito zomwe zimafuna malo enieni a shaft ndi/kapena kukangana kochepa kwambiri.

3. Maberiyani ophatikizana, chifukwa cha malo awo akuluakulu olumikizirana komanso kusinthasintha kwawo, amatha kupereka mphamvu yonyamula katundu wambiri komanso kukana katundu wolemera kwambiri komanso katundu wolemera kumapeto.

4. Maberiyani ophatikizana amalipiritsa bwino kusalinganika bwino kuposa maberiyani ena ozungulira kuti achepetse mphamvu ya katundu wolemera kumapeto.

5. Chogwirira chophatikizana chimagwiritsa ntchito kapangidwe kowonda kwambiri ka chidutswa chimodzi, komwe kumatha kuchepetsa kukula kwa chipolopolo, kusunga malo ndi kulemera kwakukulu.

6. Chogwirira chophatikizana chimakhala ndi kukana kwakukulu ku kayendedwe kobwerezabwereza, zomwe zimatha kutalikitsa moyo wa chogwiriracho.

7. Chogwirira chophatikizana sichidzawonongeka ndi kuwonongeka komwe kumachitika chifukwa cha kutsetsereka kwa zinthu zozungulira zikayenda mwachangu komanso katundu wochepa kwambiri, ndipo chimakhala ndi ntchito yabwino kwambiri yochepetsera chinyezi.

8. Poyerekeza ndi ma bearing ozungulira, ma bearing ophatikizika alibe ziwalo zosuntha mkati, kotero amayenda mwakachetechete ndipo alibe malire pa liwiro pansi pa makina odzola bwino.

9. Kukhazikitsa mabearing a composite ndikosavuta, chipolopolo chopangira makina chokha ndichofunika, ndipo sichingawononge zowonjezera poyerekeza ndi mabearing ozungulira.

10. Poyerekeza ndi mabearing ozungulira wamba, mabearing ophatikizana osakhala achitsulo amakhala ndi kukana kwamphamvu kwa dzimbiri.

11. Chogwirira chophatikizana chikhoza kuuma popanda ndalama zowonjezera mafuta, mafuta odzola ndi nthawi yogwira ntchito ya zida panthawi yokonza.

12. Chogwirira chophatikizana chingagwiritsidwe ntchito chouma ngati kutentha kwambiri komanso zinthu zodetsa.
