Kenyelletso ea Sehlahisoa
Sehlahisoa se tsoelang pele sa herringbone ntle le groove ke mofuta o khethehileng oa lisebelisoa tse nang le mela e 'meli ea meno a helical a kopanang ka ho toba bohareng, ntle le li-grooves bakeng sa sesebelisoa sa ho itšeha ho tsoa. Moralo ona o etsa hore sebopeho sa lisebelisoa se kopane le ho tsoela pele, se ntlafatsa haholo matla a motso oa leino le -matla a ho jara. Leha ho le joalo, mokhoa oa eona oa ho etsa o rarahane, 'me o hloka lisebelisoa tsa ho roala menoana kapa lisebelisoa tse khethehileng, le theknoloji ea CNC interpolation bakeng sa-ka{4}step precision milling. Mofuta ona oa lisebelisoa o sebelisoa haholo ho-matla a phahameng{7}}a lebelo le phahameng ka litlhokahalo tse phahameng haholo bakeng sa ho momahana ha sebopeho,{8}}bokhoni ba ho jara{8}, le boreleli ba phetisetso, joalo ka lisistimi tsa marine propulsion le li-gearbox tsa turbine.
Likarolo tsa Sehlahisoa
1. Moralo o ntlafalitsoeng:
Khetha ka nepo li-angle tsa helix le liparamente tsa profil ea leino, 'me u tsamaise matla le tlhahlobo ea ketsiso ea meshing.
2. Sesebediswa{1}}Se hodimo sa Motjhini o Nepahetseng:
Kgetha mochini o ikemiseditseng wa ho sila wa CNC o thata ho lekana, matla a phahameng a ho nepahala, le bokgoni ba kgokahanyo bo nepahetseng ba B-(tool oscillation axis) le C-(workpiece rotation axis).
3. Lisebelisoa tsa ho Seha ka nepo le Mananeo:
Sebelisa- lithulusi tsa coated carbide kapa CBN tsa ho itšeha tsa boleng bo holimo, 'me u etse ho sila le ho hlahloba ka nepo. Lenaneo le hloka lipalo tse nepahetseng tsa lithulusi, ketsiso ho qoba tšitiso, le ho ntlafatsa maemo a ho itšeha.
4. Taolo ea Ts'ebetso e thata:
Theha mokhoa oa tšebetso oa mahlale (mohlala, rough milling-semilling{3}finish milling-finish milling sequence), etsa bonnete ba hore ho kokota ho tsitsitseng, le ho qeta hantle sebakeng sa khokahanyo ea lisebelisoa.
5. Tlhahlobo e Felletseng{1}}Le Tokiso:
Sebelisa setsi sa ho lekanya lisebelisoa ho hlahloba ka nepo boemo ba leino, tataiso ea leino le helix, 'me u etse matšeliso le liphetoho tse ntle ho sesebelisoa sa mochine kapa lenaneo ho latela liphello. Qetellong, etsa liteko tsa ho kopana le meshing le liteko tsa lerata.
Tsebo ea Bafani ba Gear
Mefuta e fapaneng ea machining bakeng sa likere tsa spiral bevel ke 1600mm ka bophara, ka mojule o moholo oa 25mm; bophara ba machining bakeng sa likere tsa spur le helical spur ke 1250mm. Ka selemo sa 2019, k'hamphani e ile ea hlahisa mechine e silang ea CNC,-mechini e silang ea liboko e sebetsang hantle haholo, metjhini e silang ea spiral bevel gear, le setsi sa ho lekanya li-gear tsa 1000mm, e e nolofalletsang ho sebetsana le likere tse nang le lintlha tse nepahetseng tsa grade 5 le 6, e leng ho matlafatsang tlholisano ea lihlahisoa tsa eona.
Thepa e tsamaisanang le lisebelisoa tsa ho futhumatsa mocheso (normalizing, carburizing, desalination, quenching le tempering, high{0}}phekolo ea khafetsa) e tsoela pele ho u bolokela nako le matsapa, ho fana ka lits'ebeletso tse felletseng.
