20Cr2Ni4A, e le ea boleng bo holimoTšepe e chitja ea motsoako, e na le matla a phahameng, ho tiea ho babatsehang, le ho tiea ho ikhethang. E sebelisoa haholo maemong a fapaneng a phetiso ea mojaro o boima, tšusumetso le ho nepahala. Ka mefuta e mengata ea litlhaloso tsa φ2 - φ500, ha e khone feela ho fihlela litlhoko tsa ts'ebetso ea likarolo tse nyane tse nepahetseng empa hape e ka phethahatsa litlhoko tsa ho jara mojaro tsa likarolo tse kholo tsa sebopeho.
I. Sistimi ea Phetiso ea Mechini e Boima
Likarolo tsa ts'ebeliso: Li-gear tse boima, li-gear tsa li-gearbox, li-gear tsa axle tse khannang, li-shaft tsa spline, li-shaft tsa transmission cross
Tlhaloso ea Sebaka: Mechining ea merafo, mechini ea kaho le literaka tse boima, likarolo tsa phetisetso li hloka ho mamella torque e phahameng haholo le moroalo oa tšusumetso. Kamora ho kenya ka har'a carburizing, lera la bokaholimo ba 20Cr2Ni4A le fumana boima bo phahameng, ha karolo ea mantlha e boloka matla a phahameng, a ka hanelang ho senyeha ha bokaholimo ba meno le ho robeha ha motso oa meno, e leng se eketsang bophelo ba ts'ebeletso ea lisebelisoa haholo.
II. Lifofane le Lisebelisoa tsa Sesole
Likarolo tsa ts'ebeliso: Likarolo tsa moqomo oa enjene ea lifofane, likarolo tsa lisebelisoa tsa ho lulisa, likarolo tsa sebopeho sa libetsa
Tlhaloso ea sebaka: Thepa ena e latela maemo a GB/T 3078-2008 bakeng sa tšepe ea alloy ea boleng bo holimo 'me e na le khanyetso e ntle ea mokhathala. E loketse libaka tsa lifofane le lisebelisoa tse khethehileng moo ho tšepahala ha thepa ho leng bohlokoa haholo.
III. Li-mold tse nepahetseng le li-jig tsa lisebelisoa
Likarolo tsa kopo: Cold heading die, foreimi ea hlobo e nepahetseng, sesebelisoa se matla haholo, phini ea ho fumana
Tlhaloso ea Sebaka: Tšepe e chitja ea boholo bo bonyenyane (φ2 - φ50) 20Cr2Ni4A e atisa ho sebelisoa ho etsa likarolo tsa hlobo tse thata le tse tšoarellang haholo le lisebelisoa tsa lisebelisoa. Botsitso ba eona bo botle ba tekanyo ea kalafo ea mocheso bo netefatsa ho nepahala ha ho beoa ha mokhoa oa ho pheta-pheta ts'ebetsong e nepahetseng.
IV. Ts'ebetso ea Oli le Merafo
Likarolo tsa ts'ebeliso: Sehokelo sa ho cheka, sleeve e sa tsofaleng, shaft e kholo ea crusher
Tlhaloso ea Sebaka: Libakeng tse thata tsa merafo le tsa ho cheka oli, lisebelisoa li tlameha ho mamella ho senyeha ho matla ho bakoang ke lehlabathe le khatello e boima. Ho tiea ho hoholo ha 20Cr2Ni4A ho netefatsa thepa e tšoanang ea mechini bohareng ba likarolo tse kholo (tse bophara ba 100mm kapa ho feta), ho fihlela litlhoko tsa maemo a feteletseng.
V. Lipalangoang tsa Terene le Kaho ea Likepe
Likarolo tsa ts'ebeliso: li-gear tsa ho hula tsa locomotive, li-shaft tsa bogie pin, lihokelo tsa molamu oa rudder
Tlhaloso ea Sebaka: Likarolo tsa lipalangoang tsa terene le likepe li lula li pepesehetse meroalo le ho thothomela ho fapanyetsanang. Motsoako oa matla le ho tiea ha thepa, hammoho le boemo ba khatello ea khatello ea lera la bokaholimo ka mor'a ho kenngoa ha carburizing, li ka liehisa ho qalisoa ha mapetso a mokhathala le ho netefatsa polokeho ea ts'ebetso.
