Sehlahla sa selemoke karolo e kopanyang e kopanyang mesebetsi ea li-elastic elements le bushings tsamaisong ea mechine. E sebelisoa haholo maemong a joalo ka ho monya ho ts'oenyeha, ho buffer, ho beha maemo le ho fokotsa likhohlano. Mesebetsi ea eona ea mantlha e ka akaretsoa ka tsela e latelang:
1. Ho monya ho ts'oenyehileng le ho thibela ts'ebetso
Lihlahla tsa selemo li monya ho sisinyeha ha mochini le matla a ts'usumetso hang hang ka lisebelisoa tse rekerehang (joalo karabara, polyurethane kapa mehaho ea tšepe ea tšepe). Ka mohlala, tsamaisong ea ho emisoa ha likoloi, lihlahla tsa selemo li kenngoa pakeng tsa letsoho la taolo le foreimi, e ka khonang ho fokotsa ho sisinyeha ho fetisetsoang 'meleng ka litsela le ho ntlafatsa boiketlo ba ho palama. Litšobotsi tsa eona tsa elasticity deformation li ka fetola li-vibrations tse phahameng-frequency ho senya matla a mocheso le ho fokotsa kotsi ea ho resonance ea tsamaiso.
2. Fokotsa likhohlano le ho khathala
Joalo ka sehokelo sa li-interface tsa likarolo tse tsamaeang, lihlahla tsa selemo li fokotsa khohlano ea likhohlano ka ho arola khokahano e tobileng lipakeng tsa litšepe. Ka mohlala, koloi ea koloiho hlatsae sebelisa lera la ho tlotsa ka hare kapa thepa ea ho itlotsa (e kang PTFE) ho fokotsa khanyetso ea potoloho, ha e ntse e sireletsa koranta ho tloha ho apara le ho lelefatsa bophelo ba karolo. Ka mekhoa ea ho khutlisetsa morao, elasticity ea eona e ka boela ea lefella ho kheloha ha axial le ho qoba ho apara ka mokhoa o sa tloaelehang o bakoang ke ho se lumellane.
3. Tšehetso le boemo
Lihlahla tsa selemo li fana ka tšehetso e feto-fetohang bakeng sa likarolo tse tsamaeang 'me li na le mesebetsi ea ho beha maemo. Likarolong tsa liroboto tsa indasteri, li ka mamella meroalo ea radial le ho lumella ho kheloha ha li-angle tse nyane, ho netefatsa ho sisinyeha ha letsoho la roboto ha li ntse li boloka botsitso ba sebopeho. Ho feta moo, moralo oa preload o ka fetola lekhalo lipakeng tsa likarolo ho thibela lerata kapa tahlehelo e nepahetseng e bakoang ke ho hlepha.
4. Ho laola lerata
Thepa e phahameng ea damping ea thepa ea rekere e ka thibela ho ata ha lerata la vibrate. Ka mohlala, tšebeliso ealihlahla tsa rabaramotheong oa li-motor tsa lisebelisoa tsa ntlo li ka fokotsa lerata le sebetsang ka li-decibel tse 10-15. Ka li-gearbox, lihlahla tsa selemo le tsona li ka thibela tsela ea phetisetso ea molumo oa sebopeho le ho ntlafatsa ts'ebetso ea NVH (lerata, vibrate le bohale).
5. Eketsa bophelo ba lisebelisoa
Ka ho monya ka botlalo ho ts'oenyeha, ho fokotsa lerata le ho fokotsa likhohlano, lihlahla tsa selemo li fokotsa haholo tšenyo ea mokhathala oa mochini. Lipalo-palo li bonts'a hore mochining oa boenjiniere, lihlahla tse ntlafalitsoeng li ka eketsa bophelo ba likarolo tsa bohlokoa ka ho feta 30%. Mokhoa oa eona oa ho hloleha hangata ke botsofali ba lintho tse bonahalang ho e-na le ho robeha ka tšohanyetso, ho leng bonolo bakeng sa tlhokomelo e boletsoeng esale pele.
Khetho ea thepa le moralo
- Rubber bushing: theko e tlase, ts'ebetso e ntle ea ho fokotsa mocheso, empa ho hanyetsa mocheso o phahameng (hangata <100 ℃).
- Polyurethane bushing: khanyetso e matla ea ho roala, e loketseng maemo a boima bo phahameng, empa ho bonolo ho brittle ka mocheso o tlase.
- Metal spring bushing: ho hanyetsa mocheso o phahameng, bophelo bo bolelele, bo sebelisoang haholo libakeng tse feteletseng tse kang sefofane, empa ho hloka tsamaiso ea lubrication.
Lisebelisoa tse tloaelehileng
- Sebaka sa likoloi: ho emisoa ha enjine, molamu o hokelang o emisitsoeng.
- Thepa ea indasteri: ts'ehetso ea lipeipi tsa valve ea pompo, sesebelisoa sa mochini oa setempe sa hlobo.
- Lisebelisoa tse nepahetseng: sethala sa optical seismic ho itšehla thajana, boemo ba lisebelisoa tsa semiconductor.
Lihlahla tsa selemo li fihlella ho leka-lekana lipakeng tsa tšehetso e thata le phetoho e feto-fetohang ka ho kopanya mechanics ea elastic le mahlale a lintho tse bonahalang. Moralo oa eona o hloka ho nahanela ka botlalo mofuta oa mojaro (static/dynamic), frequency range le maemo a tikoloho. Mokhoa oa ka moso o tla hola mabapi le lisebelisoa tse bohlale (tse kang magnetorheological elastomers) le modularization ho ikamahanya le litlhoko tse rarahaneng tsa boenjiniere.
