Mtengo wa 14X-27-11751COLLAR
Mu njira yotumizira, kuyenda, ndi kugwira ntchito kwa ma bulldozers, kolala ya shaft ndi gawo lokhazikika lomwe limayikidwa pazigawo za shaft. Amagwiritsidwa ntchito kwambiri pochepetsa kusamuka kwa axial kwa magawo ena pa shaft (monga magiya, mayendedwe, ndi ma hubs), kuwonetsetsa kuti gawo lililonse limagwira ntchito mokhazikika pamalo omwe adakhazikitsidwa. Ngakhale kuti dongosololi ndi losavuta, limagwira ntchito yosasinthika pakugwirizanitsa zida, kukhazikika kwa ntchito, ndi chitetezo cha zigawo.1, Basic Structure and Classification of CollarsStructural features: Collar nthawi zambiri imakhala mphete{3}}chigawo chachitsulo chooneka ngati chitsulo, chokwanira bwino pakati pa dzenje lamkati ndi m'mimba mwake. M'mimba mwake wakunja ndi wokulirapo pang'ono kuposa m'mimba mwake, ndipo m'lifupi mwake amapangidwa molingana ndi zofunikira za mphamvu (nthawi zambiri 1/3-1/2 ya m'mimba mwake). Mbali ina ya kolala imakhala ndi mabowo (poyikira zomangira zomangirira) kapena mipata yamakiyi (yolumikizidwa ndi shaft kudzera pa makiyi athyathyathya) kuti muwonjezere mphamvu yokonza ndi shaft; Pamwambapo nthawi zambiri amathandizidwa ndi kupewa dzimbiri (monga galvanizing, blackening) kuteteza dzimbiri m'malo a chinyezi.Magulu akuluakulu: Kolala yokhazikika: kapangidwe kamene kamapangidwa ndi shaft (yopangidwa ndi kupangira kapena kuwotcherera), yomwe imagwiritsidwa ntchito kwambiri m'zigawo zazikulu za shaft monga ma shafts opatsirana ndi ma axles oyendetsa, omwe ali ndi malo olondola kwambiri, oyenera kupirira ndi mphamvu zazikuluzikulu. anasonkhana chigawo chodziimira pa kutsinde, ogaŵikana: Kulimbitsa wononga kolala: Kukhazikika ndi kukanikiza 1-2 kumangitsa zomangira (ndi nsonga kapena lathyathyathya malekezero) pamwamba pa kutsinde, kapangidwe ndi losavuta komanso yosavuta disassemble, koma malo mphamvu ndi otsika, oyenera katundu wopepuka kapena malo osakhalitsa (monga gudumu lothandizira ndi theka la chiwongolero cha Clam). mphete zolumikizidwa ndi mabawuti, zokhala ndi dzenje lamkati ndi kusokoneza kwa shaft. Pambuyo pomanga, imapanga mphamvu yowunikira kuti ikhazikike, popanda kupanikizika (poyerekeza ndi zomangira zomangira). Ndioyenera pazambiri zapakatikati (monga kuyika kwa ma axles othandizira).
matekinoloje ofunikira
2. Dongosolo loyenda: Makolala omwe amatha kuchotsedwa pa ekisi ya gudumu loyendetsa, gudumu lothandizira, ndi gudumu lowongolera amagwiritsidwa ntchito kuti apeze mphete yamkati ya mayendedwe. Zida zake ndi 45 # zitsulo (zozimitsidwa ndi kupsya mtima), ndipo mitundu ina yolemera-yantchito imagwiritsa ntchito chitsulo cha 40Cr alloy (hardness HB220-250).
3. Chipangizo chogwirira ntchito: Mphete za shaft pa shaft ya ma hinge shaft ndi dothi lomasula mkono shaft nthawi zambiri zimakhala zamtundu wa clamping, womwe umagwiritsidwa ntchito molumikizana ndi ma bere olowa kuti ateteze kusuntha kwa axial kwa ma fani panthawi yokankha nthaka. Zinthuzo ndi zitsulo zotayidwa (ZG35), zomwe zimayendera mphamvu ndi kulimba.
2. M'kati mwa dzenje pamwamba pa kolala yotayika iyenera kukhala yosalala (ndi roughness ya Ra1.6 μ m kapena zochepa) kuteteza kukwapula pamwamba pa shaft pakuyika; Maboliti a kolala yotsekera akuyenera kugwiritsa ntchito-maboliti amphamvu kwambiri (giredi 8.8 kapena kupitilira apo) kuti atsimikizire kulimba kokhazikika.
