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

 

1. ʻO ka manaʻolana hoʻomohala o nā bea plastik

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

2.ʻO nā mea lawe palaki a me pono

TʻOi aku ka haʻahaʻa o ke kumu kūʻai o ka plastic ma mua o nā bearings metala, a ʻoi aku ka waiwai o nā ʻano mea plastik ahoʻohana ʻia ma nā ʻoihana he nui, nā mea plastik maʻamauhe nylon, polytetrafluoroethylene, polyethylene a me PEEK.

ʻO ka paʻa palaki is versatility, hoʻokele waiwai a me ka maʻemaʻe . Nui nā kumu kūʻai haʻahaʻa i loaʻa no nā noi like ʻole. Hoʻohana pinepine ʻia nā bearings plastik me nā mea hoʻohui thermoplastic me ka fiber matrix a me ka lubricant paʻa, nona ka ikaika maikaʻi a me ka coefficient friction haʻahaʻa mau.

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

(1) Lubrication pono'ī

ʻO ka plastic's nā hiʻohiʻona kūlohelohe, lubricates i nā bearings, hoʻemi i ka lohi o ka hoʻomaka ʻana a mālama i ka maʻemaʻe o ka wahi. Hoʻohana ʻia ka liʻiliʻi liʻiliʻi o ka bearing i ka hoʻomaka a hoʻokani i ka hana o ka lubricating i ka bearing, akā hiki ke nānā ʻole ʻia ka hoʻololi ʻana o ka bearing. ʻOi aku ka maikaʻi o kēia i nā bearings plastic no nā noi meaʻai, no ka mea, ua kaupalena ʻo FDA i ka hoʻohana ʻana i nā lubricants i nā mīkini hana meaʻai. Eia kekahi, ʻoiai e pili ana ka lepo a me nā mea ʻē aʻe i ka lubricant a hana i kahi papa lepo, no nā bearings plastic, e hoʻopili wale ʻia nā ʻāpana i loko o ka bearing a ʻaʻole e pili i ka hana.

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

Hiki ke hana mau nā bearings i kēlā me kēia mahana ma waena o -4° C a me 260° C a hiki ke pale i ka wela wela a hiki i 600° F. Hiki ke like ka ikaika o ka laau palaka e like me ka laau metala, aka, o ka hali lahilahi ka paia, maʻa mau 0.0468 "- 0.0625" mānoanoa. Hāʻawi nā paia ʻoi aku ka maikaʻi o ka hoʻokuʻu ʻana i ka wela, e hopena i ka nui o ka hana a me ka hoʻemi ʻana i ka lole. Eia kekahi, ʻoi aku ka māmā a me ka liʻiliʻi o ka deform o nā paia lahilahi, e kūpono ana i nā noi me nā pilikia kaumaha.

(3) Hana kaiapuni

Ma muli o ke kaumaha māmā o ka plastic, ʻoi aku ka maikaʻi o nā bea plastic. ʻAʻole koi nā bearing palaki i nā uhi hou a i ʻole nā ​​​​mea hoʻohui e hana i nā hopena like me nā ʻāpana metala i hoʻohui ʻia me nā mea ʻino. Eia kekahi, pono ka hana plastic ma kahi o 10-15% ka aila i hoʻohālikelike ʻia i ka nui o ka alumini a i ʻole ke kila.

(4) Kūʻē kemika maikaʻi

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

(5) Hāpai manuahi ʻole mālama

E koho i ka plastik pono e like me ka hoʻohana ʻana, a hiki i ka bearing ke pale i ka corrosion i ka manawa. Ma hope o ka hoʻokomo ʻana, he lōʻihi ke ola lawelawe o ka bearing plastic a ʻaʻole pono e hoʻololi. Hiki i ka corrosion ke hoʻokuʻu i nā bearings metala ma kahi, ʻaneʻane hiki ʻole ke wehe ʻia me ka ʻoki ʻole ʻana. He mea maʻalahi ka lawe ʻana i nā bearings plastik.

(6) Ke kumu kūʻai haʻahaʻa o nā plastic

ʻOi aku ka maikaʻi o nā plastics ma mua o nā metala. No laila hiki ke hoʻemi ʻia nā kumukūʻai i nā bearing plastik a me nā pahu plastik
