Ndi zinthu ziti zomwe zimapangidwa ndi powder metallurgy?

Theufa zitsulo zigawoamagwiritsidwa ntchito pazida zapakhomo, zida zamagetsi ndi makina osokera ndizofala kwambiri. Ngatizitsulo zopangidwa ndi zitsuloakhoza kutchuka m'mafiriji, mafani a makina ochapira, ndi makina osokera, zopindulitsa zamakono ndi zachuma zidzakhala zazikulu kwambiri.

Mafiriji apanyumba, ma air conditioners, mafani amagetsi, ma ventilators, makina ochapira, zotsukira, makina ochapira chakudya, shavers zamagetsi, zowumitsira tsitsi, ma massager amagetsi, zojambulira matepi, zojambulira mavidiyo, zomvera zophatikizika, etc., ndizomwe zimagwiritsidwa ntchito kwambiri pazida zapakhomo ndipo ndizofunikira kwambiri zitsulo zokhala ndi mafutaufa zitsulozida zomangira zomwe zimagwiritsidwa ntchito pazinthu zingapo zoyimilira monga makina ochapira, ma compressor afiriji amafiriji apanyumba, ndi mafani amagetsi.

Kumayambiriro kwa zaka za m'ma 1970, General Electric Company ya ku United States inasintha zigawo ziwiri zazitsulo zodulira potumiza makina ochapira ochapira "oyambitsa" kukhala magawo opangidwanso ndi zitsulo za ufa. Magawo awiriwa ndi chubu lotsekera ndi chubu lozungulira.

The redesigned powder metallurgy spin chubu ndi gawo limodzi. Ngakhale kuti makulidwe onse a khoma kumapeto kwapansi amachepetsedwa, ali ndi mphamvu zokwanira zokwanira ndipo n'zosavuta kupanga.

Kuchuluka kwa khoma la sipinachi kumachepetsedwa, kotero kuti makulidwe a khoma la chubu lotsekedwa ndi kuwonjezeka, zomwe zimapangitsa kuti zitsulo zazitsulo zotsekedwa zikhale ndi mphamvu zofunikira.

A limodzi ufa zitsulo spin chubu amapangidwa ndi ufa zitsulo zitsulo F-0008-20, ndi kachulukidwe wa 5.9-6.1 pa lalikulu centimita. Ufa zitsulo zitsulo za kachulukidwe izi ali mokwanira mkulu structural mphamvu. The chibadidwe mbali ya ufa ndondomeko zitsulo ndi kuti mbali opangidwa ndi chofunika kukula ndi roughness kulondola kwa kubala pamwamba. Anzake atha kupereka mphamvu zolimbikitsira zopangira shaft yoyendetsa ndi chubu lotsekera. Chokhacho chotsatira ndikudula chamfer yaying'ono pamtunda waukulu wakunja.

Theufa zitsulo loko zigawochubu wokhala naye amapangidwa ndi ufa zitsulo zamkuwa FC-0205-40. Kachulukidwe wazinthu ndi 6.8-7.2g pa lalikulu centimita. Kuphatikiza kwa mkuwa ndi kachulukidwe kake ndi kokwera kuposa kwa chubu cha spin kuti malo a notch akhale ndi mphamvu zokwanira ndipo ali ndi kukana kwa abrasion ku clutch ya masika. The matekinoloje makhalidwe ufa zitsulo tolerances yeniyeni dimensional, yosalala pamwamba mbali, ndi flange incisions akhoza kupangidwa ndi kukanikiza popanda processing wotsatira.

The redesigned powder metallurgy loko chubu ndi spin chubu kusunga ndalama zoposa 250,000 US madola pachaka, amene kwambiri kusintha mlingo wa kufala.
