14X-27-11311GEAR

1. Kepo ea mobu:
Seteishene sa helical gearbox se hloka ho mamella litlamorao tse fetohang khafetsa mme se amohela carburizing e tebileng (botebo ba 1.2-1.8mm)
Case: Shantui SD32 final drive planetary gear e na le nako ea bophelo ea lihora tse 8000 maemong a thata a majoe.
2. Ts'ebetso ea merafo:
+ Thepa e fapaneng ea bevel e ntlafalitsoe hore e be lisebelisoa tsa 18CrNiMo7-6, e eketsang khanyetso ea eona ea ho senya ka makhetlo a mararo.
Sekema sa ho tlotsa: ho pholisa oli e qobelloang + oli ea gear ea khatello e feteletseng (sehlopha sa viscosity ISO VG320)
3. Kaho ea mekhoabo:
·Eketsa valve ea ho hema ka lebokoseng la gear ho thibela mouoane oa metsi ho kena le ho baka emulsification ea oli. Kalafo ea "nickel plating" (botenya ba 20-30 μm) holim'a lisebelisoa bakeng sa ho hanyetsa kutu.

1. Ho hola ha mokoti holim'a leino:
Motso oa sesosa: khatello ea maikutlo e feteletseng + mafura a fokolang
Tharollo: Sebelisa mafura a khatello e feteletseng e nang le MoS ₂+eketsa ho thatafala ha leino holim'a leino
2. Meno a robehileng:
Sesosa sa motso: boima ba tšusumetso + bofokoli ba lintho tse bonahalang
Tharollo: Ho hlahloba liphoso tsa Ultrasonic + ho ntlafatsa ts'ebetso ea kalafo ea mocheso
3. Ho kopanya leino holim'a metsi:
Motso oa sesosa: Ho phatloha ha filimi ea oli ho bakoang ke mocheso o phahameng
Tharollo: Eketsa sistimi ea ho futhumatsa oli (e nang le mocheso oa oli o laoloang ka tlase ho likhato tse 80)
Motso oa mokhathala o phatloha:
Sesosa sa ho qala; Ho fapanyetsana khatello ea maikutlo
Tharollo: Rot corner rolling+shot peening ho matlafatsa

1. Moralo oa ho fokotsa lerata:
· Ho poma likere (tse nang le maqeba a meno a chamfered le meno a sebopeho sa moropa) ho fokotsa lerata la meshing ka 15dB
Case: Komatsu D155AX-8 gearbox gear sete e fihlella phokotso ea lerata la 72 decibel ka phetoho.
2. Tlhokomelo e bohlale:
·Sensor e hokahaneng ea vibrate bakeng sa ho lekola-karolo ea nako ea 'nete ea hore na leino le ruruhile hakae
Tlhokomeliso e kholo ea data: Iketsetse litlhahiso tsa ho khutlisa ka boiketsetso ha tšenyo ea leino e feta 30%
3. Lisebelisoa tse tsoetseng pele:
·Lisebelisuoa tsa phofo ea metallurgy (tekanyo e kholo ho feta kapa e lekana le 7.4g/cm) e fokotsa boima ba 'mele ka 20% ha e ntse e boloka matla.
·Ho hanyetsa tšusumetso ea likere tsa bimetallic (meno a entsoeng ka tšepe e phahameng ea carbon le mantlha a entsoeng ka tšepe e tlaase ea carbon) e ntlafalitsoe ka 40%

1. Ikamahanya le meroalo e boima le litlamorao
Ha li-bulldozer li ntse li sebetsa (joalo ka ho sututsa mobu o thata kapa majoe), likere li tlameha ho mamella meroalo e mengata (torque e ka fihla ho makhetlo a 2-3 makhetlo a 3 ho feta boleng bo lekantsoeng), kahoo hoa hlokahala ho ntlafatsa ho hanyetsa ha fracture ka lisebelisoa tse matla haholo (joalo ka tšepe ea carburizing alloy) le ho matlafatsa profil ea meno (joalo ka ho matlafatsa metso).
2. Litlhoko tse phahameng tsa meshing tse nepahetseng
Phoso ea "gear mesh" le phoso ea profil ea leino (joalo ka ho kheloha ha molumo le phoso ea ho shebana le meno) li hloka ho laoloa ka thata (hangata ka phoso e ka tlase ho kapa e lekanang le 0.02mm), ho seng joalo e tla baka ho thothomela le lerata le eketsehang nakong ea meshing, mme e bile e lebisa ho "ho robeha ha leino" (ho phatloha ha leino) liphoso.
3. Apara ho hanyetsa le ho itšetleha ka lubrication
Khohlano ea nako e telele holim'a leino e atisa ho khathala, 'me hoa hlokahala ho ntlafatsa ho thatafala ha holim'a metsi (ho boloka boima bo bohareng) ka carburizing le ho tima, ha u ntse u itšetlehile ka setlolo sa oli ea gear (ho fokotsa khohlano le ho qhalana ha mocheso). Ka hona, ho tiisa le phetoho e tloaelehileng ea oli ea lebokose la li-gear ke tsa bohlokoa.
