No ke aha i ʻoi aku ka maikaʻi o nā bearings ball ma mua o nā bearings roller?

He mea nui nā bearings o nā mīkini a me nā lako he nui no ka mea e hōʻemi ana lākou i ka friction a hiki ke neʻe mālie o nā ʻāpana wili a me nā ʻāpana reciprocating. ʻElua mau ʻano nui o nā bearings: nā bearings ball a me nā bearings roller. Loaʻa lākou i nā ʻano like ʻole, nā nui a me nā waiwai, kūpono no nā noi like ʻole.

Hoʻohana nā bearings pōpō i nā pōpō hoʻonohonoho ponoʻī e like me nā mea ʻōwili, ʻoiai nā bearings wili e hoʻohana i nā wili cylindrical, conical a i ʻole spherical. ʻO ka ʻokoʻa nui ma waena o lākou ʻo ia ka wahi pili ma waena o nā mea ʻōwili a me nā apo. He pili kiko nā bearings pōpō, ʻo ia hoʻi he liʻiliʻi loa ka wahi pili. Loaʻa i nā bearings wili ka pilina laina, ʻo ia hoʻi he nui ka wahi pili.

Hoʻopilikia ka wahi pili i ka hana a me ka pono o ka bearing. ʻOi aku ka haʻahaʻa o ka friction a me ke kū'ē ʻana o nā bearings pōpō, ʻo ia hoʻi hiki iā lākou ke hana i nā wikiwiki kiʻekiʻe a me nā mahana haʻahaʻa. ʻOi aku ka kiʻekiʻe o ka hiki ke ukana a me ke kū'ē ʻana i ka haʻalulu o nā bearings wili, ʻo ia hoʻi hiki iā lākou ke kū i nā ukana haʻalulu kaumaha a nui.

No laila, ʻoi aku ka maikaʻi o nā bearings pōpō ma mua o nā bearings roller ma kekahi mau ʻano, e like me:

• Māmā: Hiki i nā bearings pōpō ke hoʻokō i nā wikiwiki wili kiʻekiʻe ma mua o nā bearings wili no ka mea he emi ko lākou friction a me ka inertia.

• Walaʻau: Hoʻopuka nā bearings pōpō i ka walaʻau a me ka haʻalulu liʻiliʻi ma mua o nā bearings wili no ka mea ʻoi aku ka maʻalahi a me ka pololei o kā lākou neʻe ʻana.

• Kaumaha: ʻOi aku ka māmā o nā bearings pōpō ma mua o nā bearings wili no ka mea he emi a he liʻiliʻi nā mea wili o nā bearings pōpō.

• Kumukūʻai: ʻOi aku ka liʻiliʻi o ke kumukūʻai o nā bearings pōpō ma mua o nā bearings wili no ka mea ʻoi aku ka maʻalahi o kā lākou hoʻolālā a me ka hana ʻana a ʻoi aku ka maʻamau.

Eia nō naʻe, ʻaʻole ʻoi aku ka maikaʻi o nā bearings pōpō ma mua o nā bearings roller. Loaʻa i nā bearings roller ko lākou mau pono ponoʻī, e like me:

• Hoʻouka ʻana: Hiki i nā bearings wili ke lawelawe i nā ukana radial a me axial kiʻekiʻe aʻe ma mua o nā bearings pōpō no ka mea he ʻoi aku ka nui o ko lākou wahi pili a ʻoi aku ka maikaʻi o ka hoʻolaha ʻana i nā ukana.

• ʻOʻoleʻa: ʻOi aku ka ikaika a me ke kūpaʻa o nā bearings wili ma mua o nā bearings pōpō no ka mea ʻoi aku ka liʻiliʻi o ko lākou hoʻololi ʻana a me ka hoʻohuli ʻana ma lalo o ke kaumaha.

• Hoʻonohonoho: Hiki i nā bearings wili ke hoʻokipa i kekahi kuhi hewa a me ka deflection o ke koʻokoʻo a me ka hale no ka mea he hiʻohiʻona hoʻonohonoho ponoʻī ko lākou.

I ka hōʻuluʻulu manaʻo, he ʻokoʻa nā pono a me nā hemahema o nā bearings pōpō a me nā bearings roller, a ʻo ke koho ʻana o ke bearing e pili ana i nā koi a me nā kūlana kikoʻī o ka noi.
