Hoʻokaʻawale ʻana

Hoʻokaʻawale ʻia nā bearings i ʻehā mau ʻāpana: nā bearings rolling, nā bearings plain, nā bearings contact angular, a me nā bearings balling balling self- Hoʻohana ʻia nā ʻāpana ʻōwili (e like me nā wili a me nā pōpō kila) no ka hoʻohaʻahaʻa ʻana i ka hakakā a kūpono i nā noi kiʻekiʻe -wikiwiki a kiʻekiʻe. No ka laʻana, hoʻohana ʻia nā bearings pōleʻa hohonu (me ka wikiwiki a hiki i 20,000 rpm) i nā kaʻa kaʻa, aʻo nā bearings roll tapered (me ka piʻi ʻana o 30% o ka hiki ke hoʻouka) kūpono i nā mīkini kaumaha. Ua hana 'ia nā bearings mai nā mea ha'aha'a -pilikia (e like me ke keleawe keleawe a me ka polytetrafluoroethylene). Hiki ke pale i ka wela ({11}}wela hana i emi iho a like paha me 500 degere ). Loaʻa i nā bearings lubricated wai ka -ʻoi loa ka haʻahaʻa haʻahaʻa (friction coefficient < 0.001) ma o ka hoʻohana ʻana i kahi kiʻiʻoniʻoni aila, no laila kūpono lākou i nā mea kani pololei. Hiki ke kū i nā haʻahaʻa radial a me ke axial (nā kihi pili o 15 degere -40 degere) a hoʻohana nui ʻia i nā milo mīkini. Hiki ke hoʻopololei i nā bearings pōpō ponoʻī i kahi hana hoʻopololei ponoʻī (me ka huina hoʻopaʻi deflection o 2 degere -3 degere) a kūpono no nā kaiapuni haʻalulu e like me ka mīkini ʻeli.
