ʻO ke kumumanaʻo mōʻaukala o ka neʻe ʻana o ke hali

I ke ʻano mua o ka bearing neʻe linear, ua kau ʻia kahi lālani o nā koʻokoʻo lāʻau ma lalo o kahi lālani o nā papa skid. Hoʻohana nā bearings neʻe linear o kēia au i ke kumu hana like, koe wale nō i kekahi manawa hoʻohana ʻia nā pōpō ma kahi o nā wili. ʻO ka bearing rotary maʻalahi loa ʻo ia ka bearing sleeve shaft, ʻo ia wale nō kahi bushing i hoʻopaʻa ʻia ma waena o ka huila a me ka axle. Ua pani ʻia kēia hoʻolālā ma hope e nā bearings rolling, kahi i hoʻohana i nā wili cylindrical he nui e pani i ka bushing mua, a ua like kēlā me kēia mea wili me kahi huila kaʻawale.

Ua loaʻa kahi laʻana mua o kahi bearing pōpō ma kahi moku Roma kahiko i kūkulu ʻia i ka makahiki 40 BC ma Lake Naimi, Italia: ua hoʻohana ʻia kahi bearing pōpō lāʻau e kākoʻo i kahi papa ʻaina wili. Ua ʻōlelo ʻia ua wehewehe ʻo Leonardo da Vinci i kahi bearing pōpō ma kahi o 1500. Ma waena o nā kumu like ʻole o nā bearing pōpō, ʻo kahi mea nui loa, ʻo ia ka hoʻokuʻi ʻana o nā pōpō, e hana ana i ka friction hou aʻe. Akā hiki ke pale ʻia kēia ma ke kau ʻana i nā pōpō i loko o nā hale liʻiliʻi. I ke kenekulia 17, ua wehewehe mua ʻo Galileo i ka bearing pōpō o ka "cage ball". I ka hopena o ke kenekulia 17, ua hoʻolālā a hana ka poʻe Pelekane C. wallow i nā bearing pōpō, i hoʻokomo ʻia ma ke kaʻa leka no ka hoʻāʻo ʻana, a ua loaʻa iā P Worth Pelekane ka palapala Sila Nui o ka bearing pōpō. Ua hana ʻia ka bearing wili mua me ka hale e ka mea hana uaki ʻo John Harrison i ka makahiki 1760 e hana i ka uaki H3. I ka hopena o ke kenekulia 18, ua paʻi ʻo HR hertz o Kelemania i kahi pepa e pili ana i ke kaumaha pili o nā bearing pōpō. Ma ke kumu o nā hoʻokō a Hertz, ʻo ka r o Kelemania. Ua hana ʻo Stribeck lāua ʻo Sweden's a Palmgren a me nā mea ʻē aʻe i kahi nui o nā hoʻokolohua, i kōkua i ka hoʻomohala ʻana i ke kumumanaʻo hoʻolālā a me ka helu ʻana o ke ola luhi o nā bearings wili. Ma hope mai, ua hoʻopili ʻo NP Petrov o Rusia i ke kānāwai viscosity o Newton e helu i ka friction bearing. Ua loaʻa ka palapala Sila Nui mua ma ke kahawai pōpō e Philip Vaughn o camson i ka makahiki 1794.

I ka makahiki 1883, ua hāpai ʻo Friedrich Fisher i ka manaʻo o ka hoʻohana ʻana i nā mīkini hana kūpono e wili i nā pōpō kila me ka nui like a me ka poepoe pololei, kahi i hoʻokumu ai i ke kahua o ka ʻoihana bearing. Ua hana ʻo O Reynolds i kahi loiloi makemakika o ka ʻike a Thor a loaʻa i ka hoohalike Reynolds, kahi i hoʻokumu ai i ke kahua o ke kumumanaʻo lubrication hydrodynamic.
