Liboutu tse Matla a Phahameng bakeng sa Excavator/Bulldozer

Liboutu tse Matla a Phahameng bakeng sa Sefate sa Excavator/Bulldozer e Featured

Tlhaloso e Khutšoanyane:

Liboutu tsa rona tsa ho epolla le li-bulldozer li entsoe ka tšepe ea boleng bo holimo ea alloy (mohlala, 42CrMoA), e nang le matla a holimo (ho fihla ho 12.9) le ho tiea ho hoholo. E entsoe ka hlooho ea hexagonal le sebopeho sa khoele e mahoashe, liboutu tsena li netefatsa matla a ho tiisa le ho itšebetsa, tse loketseng lits'ebetso tse boima. Liphekolo tse ka holim'a metsi joalo ka galvanizing li matlafatsa ts'oaetso ea kutu, e netefatsa ho tšoarella maemong a thata. E fumaneha ka boholo bo fapaneng (M16×60mm ho M22×90mm), e loketse lieta tsa pina, mabili a sa sebetseng, le likarolo tse ling tsa bohlokoa tsa mochini oa kaho le oa merafo. Li-bolts tsena li fana ka ts'ebetso e ka tšeptjoang le nako e telele, e leng se etsang hore e be tsa bohlokoa bakeng sa ho boloka botsitso le katleho ea lisebelisoa tse boima.

Li-tag tsa Sehlahisoa

Likarolo tsa Sehlahisoa
(1) Lintho tse bonahalang le Matla
Ts'epe ea boleng bo holimo: E entsoe ka tšepe ea boleng bo holimo e kang 42CrMoA, ho netefatsa hore bolt e na le matla a holimo le boima bo botle ho mamella tšusumetso e matla le ho thothomela ha baepolli le li-bulldozers tlas'a maemo a thata a ho sebetsa.
Kereiti ea Matla a Phahameng: Limaraka tse tloaelehileng tsa matla li kenyelletsa 8.8, 10.9, le 12.9. Liboutu tsa sehlopha sa 10.9 li na le matla a 1000-1250MPa le matla a tlhahiso a 900MPa, a fihlelang litlhoko tsa ts'ebeliso ea mechini e mengata ea kaho; Liboutu tsa sehlopha sa 12.9 li na le matla a holimo, tse nang le matla a 1200-1400MPa le matla a tlhahiso a 1100MPa, a loketse likarolo tse khethehileng tse nang le litlhoko tse phahameng haholo tsa matla.
(2) Moralo le Sebopeho
Moqapi oa Hlooho: Hangata moqapi oa hlooho ea hexagonal, e fanang ka torque e kholo ea ho tiisa ho tiisa hore bolt e lula e tiisitsoe nakong ea tšebeliso 'me ha ho bonolo ho e lokolla. Ka nako e ts'oanang, moralo oa hlooho ea hexagonal o boetse o loketse ho kenya le ho qhaqha ka lisebelisoa tse tloaelehileng tse kang li-wrenches.
Moralo oa likhoele: Likhoele tse nepahetseng haholo, hangata li sebelisa likhoele tse mahoashe, li na le ts'ebetso e ntle ea ho koala. Sebaka sa khoele se sebetsoa hantle ho netefatsa botšepehi le ho nepahala ha likhoele, ho ntlafatsa matla a ho hokahanya le ho tšepahala ha bolt.
Moqapi o Sireletsang: Liboutu tse ling li na le kepisi e sireletsang hloohong. Sefahleho se ka holimo sa sekoahelo se sireletsang ke sebaka se kobehileng, se ka fokotsang khohlano pakeng tsa bolt le fatše nakong ea ts'ebetso, ho fokotsa ho hanyetsa, le ho ntlafatsa ts'ebetso ea ho sebetsa ha baepolli le li-bulldozers.
(3) Phekolo ea Bokaholimo
Kalafo ea Galvanizing: Ho ntlafatsa khanyetso ea kutu ea bolt, hangata e entsoe ka galvanized. Lera le nang le masenke le ka thibela mafome ka katleho le ho bola ha bolt libakeng tse mongobo le tse senyang, ho lelefatsa bophelo ba tšebeletso ea bolt.
Phekolo ea Phosphating: Liboutu tse ling le tsona li na le phosphated. Sekhahla sa phosphating se ka eketsa ho thatafala le ho roala ho hanyetsa ha bolt, ha se ntse se ntlafatsa ho hanyetsa ha kutu ea bolt.
