He aha nā koi kūikawā no nā bearings mīkini mokulele, a pehea e hoʻokō ai i ke kūpaʻa wela kiʻekiʻe a me ka lubrication?

 

ʻO ka mea mua, e hoʻomaopopo kākou i nā kūlana hana o nā mīkini mokulele:

 

1. Ka wikiwiki kiʻekiʻe, ʻoi aku ka wikiwiki o ka mīkini mokulele maʻamau ma mua o 18000 rpm, a kiʻekiʻe loa nā koi no nā mea hana i ia wikiwiki kiʻekiʻe.

 

2. Ke kiʻekiʻe o ka mahana, kiʻekiʻe loa ka mahana hana o ka ʻenekini, hiki i ka mahana hana o ka bearing ke piʻi i 300 °C, pono ka mea bearing e hiki ke kū i ka mahana kiʻekiʻe.

 

3. Hilinaʻi kiʻekiʻe, inā he mokulele kīwila a he mokulele kaua paha, kiʻekiʻe loa nā koi no ka hilinaʻi, a ʻo kahi ʻokoʻa iki i loko o ka waihona he mea ia e pili ana i ke ola kanaka.

 

Ma muli o keka mahana hana kiʻekiʻe o ka bearing, ua hana ʻia ke apo waho me ka mea AISI M50 me ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa wela kiʻekiʻe, hiki ke hiki i ka paʻakikī 58HRC ma 300°C.

Ke holo nei i ka wikiwiki kiʻekiʻe, no ka mea e wili ana ke apo o loko o ka bearing, nui loa ka ikaika centrifugal, a ʻo ka ʻāpana kea o ke apo o loko o ka bearing e hali ana i ke koʻikoʻi tensile hoop, no laila ʻaʻohe mau māwae microscopic ma ka ʻili o ke apo o loko e pale aku i ka laha ʻana o ka māwae ma lalo o ke koʻikoʻi tensile, no laila hoʻohana pinepine ʻia ka mea AISI M50NiL ma ke ʻano he apo o loko.

 

Ma muli o ka wikiwiki loa, i mea e hōʻemi ai i ke kaumaha hou i lawe ʻia mai e ka ikaika centrifugal o ka pōpō kila, ʻo ka mea keramika me ke kaumaha māmā a me ka paʻakikī kiʻekiʻe, e like me ka silicon nitride (Si3N4) a i ʻole titanium carbide (TiC), hoʻohana pinepine ʻia e like me ka mea pōpō kila, a i kekahi manawa i mea e hoʻonui ai i ke kūpaʻa ʻana o ke komo ʻana o nā apo o loko a me waho o ka bearing a hōʻemi i ka friction, ua pīpī ʻia hoʻi nā raceways apo o loko a me waho me nā keramika.

 

Hiki ke ʻoi aku ka mahana o ka mīkini ma mua o 300 °C, ʻoi aku ka kiʻekiʻe ma mua o 1500 °C, pehea e hali ai i ka mahana he 300 °C wale nō, ʻo ia ka hōʻaiʻē o ka ʻōnaehana lubrication, ʻoiai, ʻo ka ʻōnaehana lubrication bearing kekahi hana nui ʻo ia ka hoʻoluʻu.

ʻO ka ʻāpana o ia mea he lubrication, ʻo ka lubrication bearing engine e like me ka lubrication o nā bearings maʻamau, no ka mea, ua kiʻekiʻe loa ka wikiwiki o ka bearing, ʻaʻole hiki ke hoʻohana i ka sila hoʻopili, no laila he ʻano sila labyrinth ka bearing engine, akā ʻoi aku ka maikaʻi o ka ʻaila lubricating āna e hoʻohana ai, no ka mea, ua kiʻekiʻe loa ka mahana hana, maʻalahi ka oxidize a me ka deteriorate o ka ʻaila lubricating maʻamau, no laila hoʻohana maʻamau ʻia ka ʻaila synthetic MIL-PRF23699HTS.

 

Inā makemake ʻoe e ʻike i ka ʻike hou aku e pili ana i nā bearing, e ʻoluʻolu e leka uila mai iā mākou:
