Mofuta ona oa shaft o na le ts'ebetso e ntle ea machining. Lits'ebetsong tse sebetsang, ha e na porosity kapa liphoso tse ling, ka hona ha e na bonnete ba ponahalo e ntle feela, empa hape e na le ts'ebetso e ntle haholo.
Ho na le mefuta e mengata ea li-gear shaft forgings. Lisebelisoa tse sebelisoang ka tloaelo li kenyelletsa 40Cr, 42CrMo, 20CrMnMo, le 20CrMnTi. Li-gear tsa 42CrMo le 40Cr hangata ke li-gear tse kholo indastering ea ho phahamisa, ha 20CrMn molybdenum le 20CrMnTi li sebelisoa haholo bakeng sa ho etsa likere mochining oa phetisetso. Likarolo tse ngata li hloka lisebelisoa tsa ho phahamisa. Ka 38-42HRC, boima ba kalafo ea mocheso ea likere bo fihletse ts'ebetso e ntle. Ka lebaka la ho thatafala ha mocheso oa mocheso oa pele, boima ba 42CrMo bo molemo haholo ho feta 40Cr, e amanang haufi-ufi le thepa ea eona. Ka mokhoa o ts'oanang, ka boima bo ts'oanang, matla a haufi haholo. Matla a tsitsitseng a 40Cr ke 6 ~; Matla a tensile a 42CrMo ke 110kg/mm2, mme matla a tlhahiso ke 95kg/mm2. Ts'ebetso e ntle haholo ho feta 40Cr.
Lintho tse 40Cr li na le boima bo botle.
Ho tima metsi ho ka thatafala ho isa bophara ba limilimithara tse 28-60, ha ho tima oli ho ka thatafala ho fihlela bophara ba limilimithara tse 15-40. Kamora ho tima le ho halefa, thepa e bonts'a thepa e phethahetseng ea mochini, kutlo e tlase, le matla a matla a mocheso o tlase. Lisebelisoa tsa lisebelisoa tsa 40Cr hangata li ts'oaroa ka mokhoa o phahameng oa ho tima kapa kalafo ea nitriding kamora ho tima le ho halefa. Ha boima bo le 174-229HBS, bo na le machinability e ntle, ka machinability e lekanyelitsoeng ea 60%. Likahare tsa khabone tse entsoeng ka thepa ea 40Cr li bolokiloe hoo e ka bang 0.40%, ka hona ho netefatsa motsoako o motle oa matla le ho tiea ha tšepe. Kenya karolo ea Cr. (Cr, Fe) 3C. Mocheso oa pele oa ho forging oa 40Cr gear forgings ke 1100 ~ 1150 ℃, 'me mocheso oa ho forging ke 800 ℃. Kamora ho qhekella, litekanyo tse fetang limilimithara tse 60 li hloka ho pholisa butle.
Moetsi oa li-gear shaft o hopotsa hore thepa ea li-gear shaft forgings e tlameha ho qala ho fihlela litlhoko tsa maemo a ho sebetsa. Ha u khetha lisebelisoa tsa ho etsa lisebelisoa, ntho ea pele eo u lokelang ho nahana ka eona ke litlhoko tsa maemo a ho sebetsa. Tšepe ea alloy hangata e sebelisoa bakeng sa ho etsa li-gear forgings tse sebetsang tlas'a meroalo e lebelo, e boima le e nang le tšusumetso. Hoa hlokahala ho ts'epahala haholo, 'me ho bohlokoa ho khetha tšepe ea alloy e nang le thepa e phahameng ea mochini. Haeba boholo ba gear bo hlokeha hore bo be bonyenyane ka hohle kamoo ho ka khonehang, tšepe ea alloy e phahameng e nang le phekolo e thatafatsang holim'a metsi e lokela ho sebelisoa. Phetiso ea lisebelisoa mochining oa merafo hangata e na le matla a holimo, lebelo le tlase la ho sebetsa, le lerōle le phahameng tikolohong e haufi. Ka hona, hangata ho khethoa lisebelisoa tse kang tšepe e entsoeng ka tšepe kapa tšepe ea tšepe, empa phetisetso ea lerata e batla e le nyane, 'me nako ea ho sebetsa ea mechine ea ofisi e batla e le tlaase. Mofuta ona oa shaft o na le ts'ebetso e ntle ea machining. Lits'ebetsong tse sebetsang, ha e na porosity kapa liphoso tse ling, ka hona ha e na bonnete ba ponahalo e ntle feela, empa hape e na le ts'ebetso e ntle haholo.
