No ke aha i ʻoi aku ka maikaʻi o ka hana o ka bearing plastik ma mua o ka bearing metala

 

1. Ka manaʻolana hoʻomohala o nā bearings plastik

I kēia manawa, ʻo ka hapa nui o nā mea kūʻai aku ʻo mālie makemake e koho i ke kaula hao no ka nā lako. Ma hope o nā mea a pau, i ka wā i hana ʻole ʻia ai nā bearings plastik, ua hoʻohana mau ʻia nā bearings metala ma ke ʻano he mea kuʻuna. Akā i kēia manawa, e ʻoi aku ka maikaʻi o ka hana o nā bearings plastik i ka wā e hiki mai ana.

2.Nā mea halihali plastik a me nā pono

TʻOi aku ka haʻahaʻa o ke kumukūʻai hana o ka plastik ma mua o nā bearings metala, a ke waiwai nui nei nā ʻano mea plastik a mehoʻohana ʻia ma nā ʻoihana he nui,nā mea palaki maʻamauʻo ia hoʻi ka nylon, polytetrafluoroethylene, polyethylene a me PEEK.

ʻO ka nā mea hoʻopili palaki is ka versatility, ka hoʻokele waiwai a me ka maʻemaʻe. Nui nā mea hana haʻahaʻa haʻahaʻa i loaʻa no nā noi like ʻole. Hana pinepine ʻia nā bearings plastik me nā mea hoʻohuihui thermoplastic me kahi matrix fiber a me ka lubricant paʻa, nona ka ikaika maikaʻi loa a me ka coefficient friction haʻahaʻa mau.

3. He aha ka hana maikaʻi o nā bearings plastik ?

(1) Hoʻowali ponoʻī

ʻO ka palakiko's nā ʻano kūlohelohe, hoʻowali i nā bearings, hoʻemi i nā lohi hoʻomaka a mālama i ka wahi maʻemaʻe. ʻO ka ʻāpana liʻiliʻi o ka bearing ua ʻaʻahu ʻia i ka hoʻomaka a pāʻani i ke kuleana o ka lubricating i ka bearing, akā hiki ke hoʻowahāwahā ʻia ka hoʻololi ʻana o ka bearing ponoʻī. ʻOi aku ka kūpono o nā bearings plastik no nā noi meaʻai, no ka mea, ua kāohi paʻa ka FDA i ka hoʻohana ʻana i nā lubricants i nā mīkini hana meaʻai. Eia kekahi, ʻoiai e pipili ka lepo a me nā ʻāpana ʻē aʻe i ka lubricant a hana i kahi papa o ka lepo, no nā bearings plastik, e hoʻokomo wale ʻia nā ʻāpana i loko o ka bearing a ʻaʻole e hoʻopilikia i ka hana.

(2) Hana ma ka mahana haʻahaʻa a me ke kiʻekiʻe

Hiki i nā bearings plastik ke hana mau i kēlā me kēia mahana ma waena o - 4° C a me 260° C a hiki ke kū i nā mahana kiʻekiʻe a hiki i 600° F. Hiki i ka ʻūpā palakiko ke ikaika e like me ka ʻūpā metala, akā ʻo ka hāpai ʻana He lahilahi ka paia, ʻo ka maʻamau he 0.0468 "- 0.0625" ka mānoanoa. ʻOi aku ka maikaʻi o ka hoʻopuehu ʻana o nā paia lahilahi, e hopena ana i ka laulā hana nui a me ka hoʻemi ʻana i ke komo ʻana. Eia kekahi, ʻoi aku ka māmā o nā paia lahilahi a emi iki ka hiki ke hoʻololi, e kūpono ai no nā noi me nā pilikia kaumaha.

(3) Hana kaiapuni

Ma muli o ke kaumaha māmā o ka plastik, ʻoi aku ka mālama pono o nā bearings plastik i ka wahie. ʻAʻole pono nā bearings plastik i nā uhi hou a i ʻole nā ​​​​mea hoʻohui e hana i nā hopena like me nā ʻāpana metala i hoʻohui pinepine ʻia me nā mea ʻino. Eia kekahi, ʻo ka hana plastik e pono ai ma kahi o 10-15% aila wale nō i hoʻohālikelike ʻia me ka nui like o ka alumini a i ʻole ke kila.

(4) Ke kūpaʻa kemika maikaʻi

ʻOi aku ka paʻa o nā bearings plastik i nā kemika a me nā mea like ʻole ma mua o nā bearings metala, a kūpaʻa hoʻi i nā ʻōpala a me ke komo ʻana o nā bearings metala. Kōkua kēia i ka mālama ʻana i ko lākou coefficient haʻahaʻa o ka friction a neʻe mālie me ka liʻiliʻi o ka hoʻopilikia.

(5) Ka hali ʻana me ka mālama ʻole

E koho i ka palakiko kūpono e like me ke kaiapuni hoʻohana, a hiki i ka bearing ke kū i ka pala i ka hala ʻana o ka manawa. Ma hope o ke kau ʻana, he lōʻihi ke ola lawelawe o ka bearing palakiko a ʻaʻole pono e hoʻololi ʻia. Hiki i ka palakiko ke hoʻopaʻa i nā bearing metala ma kahi, e aneane hiki ʻole ke wehe me ka ʻoki ʻole ʻana iā lākou. He maʻalahi ka wehe ʻana i nā bearing palakiko.

(6) Ke kumukūʻai haʻahaʻa o nā palakiko

ʻOi aku ka liʻiliʻi o ke kumukūʻai o nā plastik ma mua o nā metala. No laila hiki i nā bearings plastik a me nā bushings plastik ke hōʻemi i nā kumukūʻai
