4.14 ʻAʻole e ʻoi aku ka piʻi ʻana o ka mahana o ka bearing ma mua o ka mahana ambient e 35 °C, a ʻaʻole e ʻoi aku ka mahana kiʻekiʻe ma mua o 80 °C.

Nā hoʻoponopono wela o ke kaʻa a me nā kumu a me ka mālama ʻana

Ua ʻōlelo ʻia nā lula ʻaʻole ʻoi aku ka nui o ka mahana o nā bearings rolling ma mua o 95 °C, a ʻaʻole ʻoi aku ka nui o ka mahana o nā bearings sliding ma mua o 80 °C. A ʻaʻole ʻoi aku ka piʻi ʻana o ka mahana ma mua o 55 °C (ʻo ka piʻi ʻana o ka mahana ka wela o ka lawe ʻana i ka wela o ka ambient i ka wā o ka hoʻāʻo).

1. Ke kumu: Piʻo ke kumu a ʻaʻole ʻae ʻia ka laina waena. Kaʻina hana; kikowaena hou.

2. Ke kumu: Ua hemo nā wili kumu. Lapaʻau: E hoʻopaʻa i nā wili kumu.

3. Ke kumu: ʻAʻole maʻemaʻe ka ʻaila lubricating. Lapaʻau: hoʻololi i ka ʻaila lubricating.

4. Ke kumu: Ua hoʻohana lōʻihi ka ʻaila lubricating a ʻaʻole i hoʻololi ʻia. Lapaʻau: E hoʻomaʻemaʻe i nā bearings a hoʻololi i ka ʻaila lubricating.

5.Reason: Ua poino ka poepoe a wili paha i ka bearing.

Lapaʻau: hoʻololi i ka bearing hou. Wahi a ke kūlana aupuni, ka insulation F-class a me ka loiloi B-class, ka piʻi ʻana o ka wela o ka kaʻa e hoʻomalu ʻia ma 80K (kūʻai kūʻē), 90K (ʻano kumu). Ke noʻonoʻo nei i ka mahana ambient o 40 °C, ʻaʻole hiki ke kiʻekiʻe ka wela o ka hana o ka kaʻa ma mua o 120/130 °C. ʻO 95 °C ka wela wela loa. E hoʻohana i ka pū ʻike infrared e ana i ka mahana o ka ʻili o waho o ka bearing. Wahi a ka ʻike, ʻaʻole pono ke kiʻekiʻe kiʻekiʻe o ke kiʻekiʻe loa o ka mīkini 4-pole ma mua o 70 °C. No ke kino kaʻa, ʻaʻole pono ka nānā ʻana. Ma hope o ka hana ʻia ʻana o ka kaʻa, ma lalo o nā kūlana maʻamau, paʻa maoli ka piʻi ʻana o ka mahana, ʻaʻole e loli a hoʻonui mau ʻia me ka hana ʻana o ka kaʻa. He mau ʻāpana palupalu nā bearings a pono e hoʻāʻo ʻia.
