ʻO nā mea halihali i hoʻohana ʻia i nā pamu centrifugal ua māhele nui ʻia i ʻelua mau ʻāpana: nā mea metala a me nā mea non-metallic.

Mea Metala

ʻO nā mea metala i hoʻohana maʻamau ʻia no nā bearings sliding e komo pū me nā alloys bearing (i ʻike ʻia ʻo Babbitt alloys a i ʻole keʻokeʻo keʻokeʻo), hao hoʻoheheʻe kūʻokoʻa, kumu keleawe a me aluminika.

1. Alanui Hali

ʻO nā mea hoʻohui nui o ka lawe ʻana i nā ʻāpana (i ʻike ʻia ʻo Babbitt alloys a i ʻole nā ​​​​mea keʻokeʻo keʻokeʻo) he tin, lead, antimony, copper, antimony, a me ke keleawe, i hoʻohana ʻia no ka hoʻomaikaʻi ʻana i ka ikaika a me ka paʻakikī. ʻO ka hapa nui o nā mea hoʻoheheʻe e pili ana i nā mea hoʻoheheʻe haʻahaʻa, no laila kūpono lākou no nā kūlana hana ma lalo o 150 °C.

2. Copper-based Alloy

ʻOi aku ka maikaʻi o ka hoʻoheheʻe ʻana i ka wela a ʻoi aku ka maikaʻi o ke kūpaʻa ʻana ma mua o ke kila. A o ke keleawe-ma muli o ka hao he maikai machinability a me ka lubricity, a me kona paia i loko hiki ke hoʻopau, a me ka mea e pili ana me ka laumania ili o ke kumu. 

Mea Metala ʻole

1. PTFE

Loaʻa iā ia nā waiwai lubricating maikaʻi a me ke kūpaʻa wela kiʻekiʻe. He liʻiliʻi kona friction coefficient, ʻaʻole ia e komo i ka wai, ʻaʻole pili, ʻaʻole hiki ke hoʻohana ʻia ma lalo o ke kūlana o -180 ~ 250 ° C. Akā, aia kekahi mau hemahema e like me ka nui o ka hoʻonui ʻana i ka laina laina, ʻino ke ʻano kūpaʻa, a me ka conductivity thermal maikaʻi ʻole. I mea e hoʻomaikaʻi ai i kāna hana, hiki ke hoʻopiha ʻia a hoʻoikaika ʻia me nā ʻāpana metala, nā fibers, graphite a me nā mea inorganic.

2. Kipi

He mea pono pono'ī lubricating mea, a no ka mea, he oluolu i ka hana, a me ka oi ka lepo, o ka smoother ia mea, no laila, i ka mea o ke koho no bearings. Eia nō naʻe, ʻilihune kona mau ʻano mechanical, a ʻilihune kona kūʻē ʻana i ka hopena a me ka hiki ke halihali i ka ukana, no laila kūpono wale ia no nā manawa haʻahaʻa māmā. I mea e hoʻomaikaʻi ai i kona mau waiwai mechanical, hoʻokomo pinepine ʻia kekahi mau metala fusible me ke kūpaʻa ʻaʻahu maikaʻi. ʻO nā mea impregnation maʻamau i hoʻohana ʻia ʻo Babbitt alloy, copper alloy a me antimony alloy. 

3. Pāpale

He polymer i hana ʻia me ka elastomer, nona ka elasticity maikaʻi a me ka haʻalulu haʻalulu. Eia nō naʻe, maikaʻi ʻole kona conductivity thermal, paʻakikī ka hana ʻana, ʻo ka mahana hana ʻae ʻia ma lalo o 65 ° C, a pono ia i ka wai kahe e lubricate a hoʻomaha mau, no laila ʻaʻole hoʻohana ʻia.

4. Carbide

Loaʻa iā ia kahi moʻo o nā waiwai maikaʻi e like me ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻaʻahu, ka ikaika maikaʻi a me ka paʻakikī, ke kūpaʻa wela, a me ka pale ʻana i ka corrosion. No laila, ʻo nā bearings sliding i hana ʻia me ia he kiʻekiʻe kiʻekiʻe, paʻa ka hana, kiʻekiʻe paʻakikī, ikaika maikaʻi, a me ka lōʻihi, akā he kumukūʻai.

5. SiC

He ʻano hou ia o nā mea metala ʻole metala. Ua emi ka paakiki i ko daimana. Loaʻa iā ia ke kūpaʻa kino kino, ka pale ʻana, ke kūpaʻa wela kiʻekiʻe, ka ikaika mechanical kiʻekiʻe, ka hoʻomaʻamaʻa pilikino maikaʻi, ke kūpaʻa kiʻekiʻe o ka wela, ka mea liʻiliʻi liʻiliʻi, ka conductivity thermal kiʻekiʻe, a me ka coefficient hoʻonui haʻahaʻa. Hiki ke hoʻohana nui ʻia Hoʻohana ʻia i ka petroleum, metallurgy, ʻoihana kemika, mīkini, aerospace a me ka ikehu nuklea a me nā māla ʻē aʻe, hoʻohana pinepine ʻia e like me ka friction pair mea o nā sliding bearings a me nā sila mechanical.
