K80X86X20
Zovala za singano zimagwiritsa ntchito ma cylindrical rollers okhala ndi chiyerekezo chautali ndi m'mimba mwake kuposa 4: 1. Geometry "yokhala ngati singano" iyi imathandizira kuti ma radial alemedwe modabwitsa mkati mwa magawo ophatikizika kwambiri, omwe amapereka malo abwino kwambiri poyerekeza ndi mipiringidzo yamiyendo yofanana.
Zovala za Needle Roller
| ISO | K80X86X20 | |
| Raceway m'mimba mwake mphete | Fw | 80 mm |
| M'mimba mwake | Ew | 86 mm pa |
| M'lifupi | Bc | 20 mm |
| Chiyerekezo champhamvu champhamvu | C | 18.5 kN |
| Chiyerekezo cha static load | C0 | 47kn pa |
| Kuchepetsa liwiro | 2900 r/mphindi | |

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 |

Mipira ya thrust ndi ma fani ogudubuza opangidwa kuti azitha kunyamula katundu wa axial mokha. Kapangidwe kake kamakhala ndi makina ochapira ma shaft (ring yolimba), chochapira nyumba (ringing yotayikira), ndi cholumikizira chotchingira mpira chokhala ndi mikwingwirima yopindika, zomwe zimathandiza kuti ma axial force azitha kutumizirana mwachangu popanda kugundana kochepa. Osayenera kunyamula ma radial.
