Crankshaft ndiye gawo lalikulu lozungulira la injini. Ndodo yolumikizira ikakhazikitsidwa, imatha kusuntha mokweza ndi pansi (kubwereza) kwa ndodo yolumikizira ndikuisintha kukhala yozungulira (yozungulira).
Ndi gawo lofunikira la injini. Zinthu zake zimapangidwa ndi chitsulo chopangidwa ndi mpweya kapena chitsulo cha ductile. Ili ndi magawo awiri ofunikira: magazini yayikulu, magazini yolumikizira ndodo (ndi ena). Magazini yayikulu imayikidwa pa cylinder block, magazini yolumikizira ndodo imalumikizidwa ndi dzenje lalikulu la ndodo yolumikizira, ndipo dzenje laling'ono la ndodo yolumikizira limalumikizidwa ndi cylinder piston, yomwe ndi njira yolumikizira. .
Crankshaft processing Technology
Ngakhale pali mitundu yambiri ya crankshafts ndipo zina mwamapangidwe ndizosiyana, ukadaulo wokonza ndi wofanana.
Main process chiyambi
(1) Kugaya kunja kwa crankshaft main magazine ndi kulumikiza ndodo magazini Pakukonza mbali za crankshaft, chifukwa cha kapangidwe ka mphero yodulira yokha, m'mphepete mwake ndi chogwirira ntchito nthawi zonse zimalumikizana pafupipafupi ndi chogwirira ntchito, ndipo pali chikoka. Choncho, kugwirizana chilolezo umalamuliridwa mu dongosolo lonse kudula wa chida makina, amene amachepetsa kugwedezeka chifukwa cha kayendedwe chilolezo pa ndondomeko Machining, potero kuwongolera Machining kulondola ndi moyo utumiki wa chida.
(2) Kugaya magazini yaikulu ya crankshaft ndi magazini ya ndodo yolumikizira Njira yoperayo imatenga mzere wapakati wa magazini yaikulu monga pakatikati pa kasinthasintha, ndipo imatsirizitsa kugaya magazini ya crankshaft yolumikizira ndodo imodzi (itha kugwiritsidwanso ntchito ngati mainchesi). kugaya magazini), kugaya Njira yodulira magazini olumikizira ndodo ndikuwongolera chakudya cha gudumu logayo ndi kulumikizana kwa ma axis awiri akuyenda mozungulira. za workpiece kudzera CNC kuti amalize chakudya cha crankshaft. Njira yotsatirira imatengera kukumbatira kumodzi ndikumaliza kugaya magazini yayikulu ya crankshaft ndi magazini yolumikizira ndodo ndikuyika makina opera a CNC, omwe amatha kuchepetsa mtengo wa zida, kuchepetsa mtengo wokonza, ndikuwongolera kulondola kwa kukonza ndi kupanga bwino.
(3) Chida chachikulu cha crankshaft ndi chida cholumikizira makina a rod journal fillet chimagwiritsidwa ntchito kupititsa patsogolo kutopa kwa crankshaft. Malinga ndi ziwerengero, moyo wa ductile chitsulo crankshaft pambuyo fillet anagubuduza akhoza ziwonjezeke ndi 120% mpaka 230%; moyo wa crankshafts zitsulo zopanga pambuyo kugubuduza fillet akhoza ziwonjezeke ndi 70% mpaka 130%. Mphamvu yozungulira yozungulira imachokera ku kuzungulira kwa crankshaft, yomwe imayendetsa ma rollers mumutu wozungulira kuti azungulira, ndipo kupanikizika kwa ma rollers kumayendetsedwa ndi silinda yamafuta.
