Qalabka noocan oo kale ah wuxuu leeyahay waxqabadka mashiinka wanaagsan. Codsiyada wax ku oolka ah, ma laha wax porosity ama cillado kale, sidaas darteed ma aha oo kaliya hubin muuqaal wanaagsan, laakiin sidoo kale waxay leedahay waxqabad aad u fiican.
Waxaa jira noocyo badan oo ka mid ah been-abuurista shaft-geerada. Qalabka been abuurka ee sida caadiga ah loo isticmaalo waxaa ka mid ah 40Cr, 42CrMo, 20CrMnMo, iyo 20CrMnTi. 42CrMo iyo 40Cr gears been-abuur ah ayaa u badan kuwa waaweyn oo lagu farsameeyo warshadaha wax-qaadista, halka 20CrMn molybdenum iyo 20CrMnTi inta badan loo isticmaalo qalabka been abuurka ah ee mashiinada gudbinta. Gearsyada intooda badani waxay u baahan yihiin qalabka wax lagu qaado. 38-42HRC, adkaanta daawaynta kulaylka ee qalabka ayaa gaadhay waxqabad wanaagsan. Iyadoo ay ugu wacan tahay adkaanta daaweynta kulaylka aadka u fiican ee hore, adkaanta 42CrMo aad ayey uga fiican tahay kan 40Cr, kaas oo si dhow ula xiriira alaabtiisa. Sidoo kale, isla adkaanta, xooggu aad buu u dhow yahay. Awoodda xajinta ee 40Cr waa 6 ~; Awooda xajinta ee 42CrMo waa 110kg/mm2, xooga waxsoosaarkuna waa 95kg/mm2. Waxqabadka ayaa aad uga wanaagsan 40Cr.
40Cr walxaha waxay leeyihiin adkeysi wanaagsan.
Deminta biyuhu waxay adkeyn karaan dhexroorka 28-60 millimitir, halka deminta saliidda ay adkeyn karaan dhexroorka 15-40 millimitir. Deminta iyo xanaaqa ka dib, maaddadu waxay soo bandhigaysaa sifooyin farsamo oo dhammaystiran oo heersare ah, dareen hoose oo hooseeya, iyo saamaynta heerkulka hoose. 40Cr gear forgings waxaa badanaa lagu sakhraa daminta damin-soo noqnoqda sare ee dusha sare ama daawaynta nitriding ka dib deminta iyo xanaaqa. Marka engegnaanta ay tahay 174-229HBS, waxay leedahay mashiin wanaagsan, oo leh mashiin qiyaas ah 60%. Maaddada kaarboonka ee 40Cr been-abuurka walxaha waxaa lagu hayaa qiyaastii 0.40%, sidaas darteed hubinta isku-darka wanaagsan ee xoogga iyo adkaanta birta. Ku dar curiyaha Cr (Cr, Fe) 3C. Heerkulka hore ee been-abuurka ah ee 40Cr waa 1100 ~ 1150 ℃, heerkulka foornadana waa 800 ℃. Ka dib been-abuurka, cabbirrada ka sarreeya 60 millimitir waxay u baahan yihiin qaboojin tartiib ah.
Soo saaraha usheeda dhexe ee Gear waxay xasuusineysaa in walxaha foornada qallafsanaanta qalabka ay tahay inay marka hore buuxiyaan shuruudaha shuruudaha shaqada. Markaad dooranayso qalabka been abuurka, waxa ugu horreeya ee la tixgeliyo waa shuruudaha xaaladaha shaqada. Birta daawaha ah waxaa caadi ahaan loo isticmaalaa soo saarista alwaaxyada marsho ee ka hoos shaqeeya xawaaraha sare, culeyska culus, iyo culeysyada saameynta leh. Kalsooni sare ayaa loo baahan yahay, waana lagama maarmaan in la doorto birta daawaha leh oo leh sifooyin farsamo oo sarreeya. Haddii cabbirka qalabka loo baahan yahay inuu ahaado sida ugu yar ee suurtogalka ah, birta aluminiumka ah ee xoogga badan ee leh daaweynta adagaanta dusha sare waa in la isticmaalaa. Gudbinta marsho ee mishiinada macdanta sida caadiga ah waxay leedahay awood sare, xawaaraha shaqada hoose, iyo content boorka sare ee deegaanka ku wareegsan. Sidaa darteed, alaabta sida birta la shubo ama birta la shubo ayaa badanaa la doortaa, laakiin gudbinta sanqadhku waa mid yar, iyo inta jeer ee shaqada ee mashiinnada xafiisku waa mid hooseeya. Qalabka noocan oo kale ah wuxuu leeyahay waxqabadka mashiinka wanaagsan. Codsiyada wax ku oolka ah, ma laha wax porosity ama cillado kale, sidaas darteed ma aha oo kaliya hubin muuqaal wanaagsan, laakiin sidoo kale waxay leedahay waxqabad aad u fiican.
