Kuwonongeka Kwamapangidwe
Zigawo zikuluzikulu zikuphatikizapo:
- mphete yakunja: Nthawi zambiri ndi msewu wothamanga (mitundu yopanda khola imasiya mphete yakunja)
- Zodzigudubuza za singano: Zodzigudubuza-pansi zodutsira katundu kudzera pa kukhudzana ndi mzere
- Khola: Zodzigudubuza za mkuwa / zitsulo / polima (mitundu yopanda khola imapatula khola)
- Mphete Yamkati: Chigawo chosankha (mwachitsanzo, mtundu wa NA wokhala ndi mphete yamkati, mtundu wa RNA wopanda)
Classification System
- Mwa Kupanga: Yokwanira (yokwera kwambiri), yotsekeredwa (yothamanga kwambiri)
- Mwa Ntchito: Radial, thrust, kuphatikiza ma bere
- Mitundu Yapadera: Flanged (axial positioning), kuyanjanitsa (malipiro olakwika)
Ubwino Waukadaulo
| Mbali | Phindu la Engineering |
| Gawo lochepa kwambiri | Imapulumutsa 60% malo ozungulira |
| Kuchuluka kwa katundu | 300% mphamvu yapamwamba vs. mipira |
| Kukana kugwedezeka | Kulumikizana kwa mzere kumagawa kupsinjika |
| Kulondola kozungulira | ± 0.03mm kwa machitidwe olondola |
| Chidziwitso: Kuchepetsa liwiro kumasiyanasiyana ndi zinthu za khola |
Ntchito Zamakampani
- Zagalimoto: Kutumiza (mwachitsanzo, JTEKT NK17/20), ndodo zolumikizira
- Maloboti: Malunjidwe opangidwa (mtundu wokwanira wokwanira)
- Zamlengalenga: APU rotor mayendedwe othandizira
- Zachipatala: CT scanner gantry rotation (matembenuzidwe otetezeka a MRI)
- Zomangamanga: Ma hydraulic pump drives (Timken TOR 47)
Kusintha Kwachilengedwe
| Mkhalidwe | Analimbikitsa Yankho |
| Kutentha kwakukulu | Zodzigudubuza zokutidwa ndi ceramic + makola apadera |
| Media zowononga | Chitsulo chosapanga dzimbiri (SS suffix) |
| Madera okhudzidwa | Zisindikizo za milomo iwiri (2RS) |
| Kuthamanga kwambiri | Makhola a polima + mafuta opaka mpweya |

Tapered roller bearing ndi njira yodzigudubuza yolondola yomwe idapangidwa kuti izitha kunyamula katundu wolumikizana ndi ma radial ndi heavy-direction axial panthawi imodzi. Dzina lake la conical geometry ndilofunika kwambiri, ndikupangitsa kuti lizitha kuyendetsa bwino ndikusamutsa katundu wophatikizidwa.
